The game is a turn-based strategic game, aiming to imitate reality as much as possible. However it still

contains several simplifications to make the game easier to understand and more entertaining to play.

You are the managers of a well-established oil company with a diversified upstream and downstream

portfolio continuously seeking new upstream opportunities to replace the reserves and the production,

as well as to improve the efficiency of your refineries.

Freshhhfield had decided to open its oil industry to international players recently, due to a lack of

funds for putting into production the sizeable discoveries made by the National Oil Company of

Freshhhfield. Several companies entered the First International Bidround of Freshhhfield which

resulted in a significant increase of production and oil export levels of the country. Your company owns

four oil fields in Freshhhfield. Thanks to the success of the international bid round, Freshhhfields two

neighbouring countries, Freshhhia and Freshhhrock have also opened up and the three countries

formed the Oil Producer Fresshian Countries OPFC Area. Thanks to your long-lasting successful

international track record and your presence in Freshhhfield you are one of the few companies invited

to operate in the OPFC Area. The upstream industry has a long history in Freshhhia and Freshhhrock

as well, however most discovered fields could not be developed due to the lack of funds in these

closed economies in recent decades. The primary objective of OPFC countries is to find operators

who commit themselves to efficiently developing and producing the already discovered hydrocarbon

fields. Therefore no exploration licenses will be granted, and you can only bid for discovered fields.

You are delegated exclusively to the management of the OPFC Area portfolio, and you dont have to

deal with other assets of the company. Nevertheless you have access only to the free funds of your

own portfolio to acquire new opportunities here.

Your aim is to prove that you are the best managers by maximizing the cash generation of your

companys Freshhhian upstream portfolio by creating value added with both upstream and

downstream operations.

You start the upstream game with 500 million F$ (Freshhh Dollar) of cash at hand. You will also

receive 5500 million F$ for downstream operations.

Contestants are going to play for 18 turns. 1 turn in the game means 24 (or 8 in the Test Rounds)

hours in the real world, so in every 24 (or 8 in the Test Rounds) hours, there is going to be a turn

change.

(the next rounds results financial accounting and the effects of decision-making - only show when a

turn change occurs)

You start the game with a separate Upstream and Downstream budget with 500 million F$ in

Upstream and 5500 million F$ for Downstream.

You have a revolving credit of 5000 million F$ total at 10% interest rate. You can use this credit facility

to finance up to 60% of your investments (Downstream and Upstream too). In the meantime you

cannot use the credit to acquire new fields. If you exceed the 60% limit on any of your investments, the

penalty interest will be 30%.

In each turn you will be offered the chance to acquire oil fields in the OPFC Area (5 fields per turn until

turn 10, 7 fields in turn eleven and 0 fields thereafter). Each license will be offered only once. Specific

geological, fiscal and economic data and the price of the fields will also be rendered. With the help of

this information you will have to evaluate the fields and purchase them if you have sufficient amount of

funds and of course the opportunity is prospective enough. Your funds are scarce so dont waste

them on low return projects. If the IRR of a project is just a few percents, it might be better to wait for

more suitable opportunities.

After the purchase your task will be to work out and fulfil a field development program on the

field.

Your performance and the final scoring is based on the cash generated your companys

Freshhhian portfolio. We will also take into consideration and evaluate the effects of your decisions

made in the final turn. (By running a 19th turn automatically without the opportunity to make any

decisions right at the end of the game.)

You can see country specific information or elect the lincenses in the Locator. By selecting an active

license area a list of input data will appear (for details see Inputs section) and you can also acquire or

go to the selected field.

When you successfully sign an agreement, you will be navigated to another screen where the map of

the license area will appear. Here you will find 4 panels/ buttons:

Crude oil

The oil quantity that leaves the license area is sold on the average international market price at the

end of the year. Note that there can be several bottlenecks of oil sales. (See the facilities section for

details.)

Natural gas

The associated natural gas is used for power generation, or transferred to the government for free,

according to the license agreements in force in the OPFC area. (This is done automatically; the teams

do not have to deal with gas at all.)

If the teams want to plan their revenues precisely, they have to model the fiscal regime of the license

agreements as well. Each country has its own tax regime but they are quite similar. The OPFC

countries use simple royalty system. According to the regulations a single tax is levied on the oil

revenue of the company. For the tax rates of the countries please see the table below.

Oil price varies throughout the game. In the first period the price is F$ (Freshhh Dollar) 100 /bbl.

Before purchasing a development concession you will need to evaluate it. To do this, you have to

calculate the oil in place, the recoverable reserves and finally the production profile while also

considering the necessary investment, operating costs and taxes. The recoverable reserve size (i.e.

the recovery ratio) and the production profile are dependent on your field development scheme.

(Please see next section for detailed information on field development.) Note that the fields are

developed with pressure maintenance technology and ESPs (electronic submersible pumps) are used

at each production wells.

With the above specified data set and with the use of the Vasquez and Beggs (1980) formula, you cancalculate - the Bubble point pressure, the Oil formation volume factor, and the Original reserve for

undersaturated reservoir.

Following that, OOIP Original Oil In Place can be calculated

During the Recoverable Reserve calculation, use

Beggs and Robinson (1975) for the oil viscosity calculation

McCain (1991) for the water viscosity calculation. The water is assumed to be freshhh water without

any salt content.

For estimation of the recovery factor with pressure maintenance technology please use the correlation

issued in API Bulletin D14 (1967)

The production is separated into two phases, waterless production and production with water. The

total liquid (water+oil) production level of a field with a given well network is constant in the entire life

of a field (without taking into consideration the bottlenecks of the surface infrastructure) but watercut of

the production changes in time. For the calculation of the production profile you may use the followingformulas:


12/50

12

For waterless production portion(from sensitivity calculation made by numerical simulation)

Wlp= waterless (till 1% of water contain) production portion of the total production

Wlp=0.6047-0.035*log(o/w)+0.02861*log(Wd)-0.0342*log(h)+0.06*(heff/h)-0.0067*log(k)

where;

(Wd) Well distance interval = 2000 < distance between the injectors and producers < 10000 [ft]

Reservoir total thickness interval (h) = 40 < thickness < 300 [ft]

Permeability interval = 1 < k < 1000 [mD]

Over (or below) the limits the maximal (minimal) limit value has to be used

Distance between injectors and producers = 2*(A/(n+m)/3.14)^0.5

where:

A: field area [sq ft]

n: number of producers

m: number of injectors

ROOIP in the waterless production phase =ROOIP*Wlp* Sp, where

Sp= Scheme parameter, a correction factor depending on the injection well pattern:

At five point system (producer -injector ratio = 1) Sp=1

At seven or four point system (producer -injector ratio = 2) Sp=0.9

At nine point system (producer -injector ratio = 3) Sp=0.8

Sp can be calculated directly from the final producer-injector rate for a middle point


13/50

13

When the produced oil amount in the waterless production phase exceeds ROOIP*Wlp* Sp, the

waterless phase alters to production with water phase.

In production with water phase

For Field level Water Oil Ratio prediction use Timmermann (1971) formula, where;

Np= cumulative oil production [bbl], its domain: ROOIPWlp < Np < ROOIP

a, b = reservoir specific constants, can be determined from the first and last point of the curve

1st point (starting of the water production) WC=1%, Np=ROOIPWlp

2nd point (end of potential production) WC=99%, Np= ROOIP

For well level estimations you may use the following equations

Average producer productivity equation:

where:

qf = qo+qw[bbl/d]

re=drainage radius [ft]

rw= wellbore radius [ft]

re = (A/n/3.14)^0.5




14/50

14

Estimationof the average injector final productivity:

where

iw[bbl/d]

Kw= average water permeability (assumed to be equal to k)

rei = middle distances between the injectors and producers

rei= (A/(n+m)/3.14)^0.5

where:



m: number of injectors

As the game itself, the model for the estimation of the production of a field should also be built using 1

year long periods.

,

To bring up the precious oil from the depths of the earth, you will need to develop the field. For this

purpose, producer and injector wells are needed as well as a well-designed surface facility. The

design of the transportation capability is also your task.

For a well-functioning field development program you need to focus on the produced amount, the

capacities of the equipment (bottleneck effect) and the timing of your development. Both the

production and injection capacity, as well as the surface processing or transportation capacity can be

the bottleneck in the system. Also, according to the rules of OPFC, the daily oil production of a field

cannot be greater than one third of its storage capacity. It is important to optimise the number of wells

and capacity of the surface infrastructure to make the operation of the field as efficient as possible.

Before starting the field development you have to take into account that


15/50

15

the granted concession rights are valid for 20 years or turns.

All fields need to be developed with pressure maintenance technology.

For security reasons the maximal drawdown pressure at water injector wells is 1500 psia.

Minimal bottom hole pressure at producer wells is 50% of reservoir pressure. Pressure build-

up follows hydrostatic tendency. g is 10 m/s2.

In the Development panel you will find the facilities that can be constructed (Producer well, Injector

well, Oil processing train, Storage tanker, Road, Rail and Pipeline transportation units). By clicking on

Investmentbutton, you can see the CAPEX of the units to be construced.

You can select the number of units (in case of wells), or the capacity (in case of other facilities). When

you have set the desired number or capacity of all the facilities, you may select Accept. Keep in mindthat there are certain limitations for the construction of production facilities.

Note that in one turn you are only able to access the build panel once. That means that you have one

opportunity in each turn to decide what facilities are to be constructed.

* Note: The number of units is maximised not the capacity.

It can happen that the revenues of a field will not cover the OPEX and the taxes payable for the given

field. In this case you can abandon the field at zero charge in each period. However, you cannot

abandon a field if there are ongoing construction works within its perimeters.

Below you will find a summary of the different equipment and facilities that could be developed and the

cost-functions of the CAPEX and OPEX related to them.

CAPEX is charged when the construction order is given (except for Oil Processing train). When the

Processing train is being constructed the first part of the CAPEX is charged on the spot while the

remaining parts are charged at the beginning of the following turns.Facilities start the operation in the


16/50

16

turn following the construction except for the Processing train that is in operation from the 3rd

year

following the start of construction.

Production wells are the elemental tools of oil mining. CAPEX of one unit depends on the depth to be

drilled and geological factors. The construction costs contain the installation of ESP (Electrical

Submersible Pump), pipelines connecting to the CPU (Central Processing Station) and other well site

infrastructure. As pressure maintenance technology is used for field development, injector wells must

also be drilled Injector wells are fed by the water of nearby rivers and lakes. Significant part of

operational costs of wells connected to the amount of liquid produced, however the regular

maintenance of wells requires notable financials as well. Capital and operational costs for producer

and injector wells for can be calculated as follows:.

Wells

CAPEX - fix Production or injector wells drilled in period [#] * F$ 5 mln/well

CAPEX - variableProduction or injector wells drilled in period [#] * F$ 0.3 mln/1000 ft * Reservoir

OPEX - fix Production or injector wells in operation [#] * F$ 0.25 mln/well/year

OPEX - variable Produced or injected liquid amount [MMbbl/year]^0.8 * F$ 0.3 mln/MMbbl

Oil processing train or CPU is the heart of each oil field. Their main task is to transform the produced

raw oil into a transportable and marketable quality product. The construction of an oil processing train

takes 3 years. CAPEX emerges as follows: in the first year 30%, in the second year 50%, in the third

year 20% of total cost. As evident as it is the construction cost depends on the capacity of the unit,

with significant initial investment. The OPEX of the unit is also related to the maximal capacity. One

processing train can be built in each period (until reaching 4 trains) of which the minimal capacity is

1,000 bbl/day while the maximal capacity is 50,000 bbl/day.

OPEX - fix Processing trains in opearation [#] * F$ 0.5 mln/train/year

OPEX - variable Processing train capacity [MMbbl/year] ^0.8 * F$ 2 mln/MMbbl

Storage tankers are required for temporary oil storage, as in some cases the transportation is not

possible immediately. CAPEX of these facilities are proportional to the size and capacity of the unit.

However the operational costs are unit based. One tanker can be built in each period (until reaching 6

tanker units) of which the minimal capacity is 1,000 bbl/day while the maximal capacity is 150,000

bbl/day.

OPEX - variable N/A

Players may choose between three different means of transportation. One transportation system can

be built in each period from all types of transportation infrastructures.

For road transportation a road connecting to the main system must be built together with truck filling

heads. Road CAPEX must be paid in the first year road is constructed and only have to be paid.

Whereas filling station CAPEX must be paid each time additional road transport capacity is

constructed. OPEX of road has fix part due after a road is constructed and a variable part depending

on the length of the road. Fix filling station OPEX must be paid based on the number of filling stations

in operation. The external transportation costin case of road transport is 7 F$/bbl(in excess of the

CAPEX and OPEX of the facilities). One road transportation unit can be built in each period (until

reaching the total road transportation capacity of 50,000 bbl/d) of which the minimal capacity is 1,000

bbl/day while the maximal capacity is 50,000 bbl/day.

CAPEX - variable Truck filling capacity built in period [Mbbl/d]^0.8 * F$ 0.5 mln/(Mbbl/d)

OPEX fix Truck filling stations in operation [#] * F$ 1 mln/#/year

OPEX - variable N/A

For transportation with train a pipeline to and a filling station at the nearest rail line must be

constructed. Pipeline CAPEX has a notable large fix part and a variable part dependent of the length

and the capacity of the pipe. CAPEX of filling station follows the same logic, self-evidently without

taking into consideration the distance. Note that each time a new pipeline is constructed a new filling

station must also be built. Fix OPEX of both units is based on the number of facilities built whilevariable OPEX of the pipeline depends on its capacity. The external transportation cost in case of


18/50

18

rail transport is 5 F$/bbl(in excess of the CAPEX and OPEX of the facilities). One rail transportation

unit can be built in each period (until reaching the total rail transportation capacity of 100,000 bbl/d) of

which the minimal capacity is 1,000 bbl/day while the maximal capacity is 100,000 bbl/day.

The third mean of transporting the crude oil to the international market is using an pipeline. In this case

a pipeline to the nearest international transportation pipeline and a connection point must also be

constructed. If pipeline capacity has to be increased, a new pipeline and a separate connection point

has to be built. The CAPEX and OPEX functions of these facilities are quite similar to that of the

railway units, however they have significantly higher initial costs. Meanwhile the external

transportation cost in case of pipeline transport is 3 F$/bbl(in excess of the CAPEX and OPEX of

the facilities). One pipeline transportation unit can be built in each period (until reaching the total road

transportation capacity of 500,000 bbl/d) of which the minimal capacity is 1,000 bbl/day while the

maximal capacity is 500,000 bbl/day.

OPEX - variable N/A

OPEX is incurred from the year the facility is in operation. OPEX is charged at the end of each turn.

Parts of OPEX that not depend on the actual throughput of a unit are paid for all the commissioned

infrastructure irrespective of their utilisation.

It is important to note that:

All costs are multiplied by a Country factor representing the price differences of different countries.

Construction of facilities takes 1 year (except for Oil processing trains). The operation begins in the

year following the construction year.

Facilities operate 300 days a year, taking into consideration the time spent on repair, adjustment and

maintenance.

In case more than one means of transportation is available, oil is transported via the cheapest way. If

the capacity is not enough the rest of the production is transported via other existing means.

A regional company sold its refinery construction. Your company has bought it, and it is your task to

make it as profitable as possible.

Gasoline and diesel product lines have already been built. The refinery will be operational from the

start.

Units available from the start:

Crude Distillation Unit (CDU)

Heavy Naphtha Hydrotreater

Light Naphtha Isomerisation Unit

CCR Reformer Unit

Gasoil Hydrotreater

The refinery will use crude bought from the market. The utilization rate can be set by adjusting the

imported crude volume.

Due to the limitations of technical processes, the annual refinery (CDU) utilization rate can not be less

than 60%. As a simplification, this restriction does not apply for other refinery units. The minimumimported crude volume is always set automatically to match the minimum utilization rate. Some units


22/50

22

have a maximum capacity specified. For the other plants, where it is not specified, there is no

maximum throughput limit.

The company will be able to convert the products into money at market prices.

During the game, you have to make several decisions to operate and expand your refinery in an

optimal way. The goal is to achieve maximum amount of money at the end of the defined period.

The aim of the programmers was to create a game as realistic as possible, but it still contains several

simplifications to make the game easier to understand and more entertaining to play.

Here you can find a long term prognosis about the changes in refinery product prices.( . $, , $ .

Each turn you have to make different decisions to optimize the efficiency of your refinery.

There will be operational decisions. You can:

Alter the path of different refinery streams by splitters

Choose catalyst for HDS/MHC Unit

Along the way, you can construct new facilities to keep up the competitiveness of your company and

to fulfill the environmental regulations and product qualities. Not all technologies are available from the

start. You can see your opportunities in the following table:

from 2013 from 2015 from 2017 from 2019

Plant availability for construction

Fuel:the energy consumed in the process to heat up the materials to the required temperature. Some

units produce fuel gas, but that is not sufficient for the refinery. Excess fuel is bought from the market

as natural gas. Natural gas is also the feed of the Hydrogen Plant. The heating value is the same for

the produced fuel gas from all refinery units and the natural gas: 50 GJ/t. If more fuel is produced in

the refinery units, than consumed, the excess fuel gas is burnt on the refinery flares.


25/50

25

Electricity:mainly intended to propel the pumps and move the feed and products, but used also for

light and for supplying control systems.

Cooling water:used in cooling processes for condensation and temperature control.

Steam: used for technological processes, heating and stripping. Some units produce more steam,

than the amount necessary for operation. This is indicated with a negative value in steam

consumption. If a unit produces steam then the excess steam is redirected to other units for usage but

it can not be sold on the market. If the amount of produced steam is not sufficient, the necessary

amount is bought from the market.

Hydrogen:Hydrogen is used in hydrotreater and isomerisation units. The price of the hydrogen varies

in time. Hydrogen can be produced or bought from the market. In the first part of the game external

hydrogen is purchased for 5000 F$/t, but starting from 2021 the hydrogen price increases dramatically

to 20000 F$/t (due to the availability from a different supplier). In case of more hydrogen is produced in

Reformer unit, than needed for refinery processes, the excess of hydrogen is burnt on the refinery

flares.

Catalyst: As a simplification, catalyst expenses are calculated as utility, except the HDS/MHC unit, in

which it is your task to change the catalyst every two years. Catalyst price is specified for each unit.

Fuel (F$/GJ) 12.4Electricity (F$/MWh) 106

Cooling water (F$/1000 m) 112

Steam (F$/GJ) 10.4

Utility prices

For all refinery units utilities are calculated proportional to the feed. Consumed hydrogen is not

calculated in the feed, but it appears in the product. That is why hydrogen consuming units have an

overall yield over 100%.

PROCESSES IN THE REFINERY

()

The first step in a refinery is the distillation of crude into different fractions. Lighter compounds are

separated in the predistillation and main (atmospheric) distillation columns. Heavy compounds have to

be distilled in a vacuum distillation column. The products of CDU are further processed in different

refinery units. Capacity of the CDU is 10000 kt/year. We would like to lay emphasis on the fact that


26/50

26

Fuelgas is used by the refinery for heating, and it does not show in the final product summary (the final

()Desulphurized naphtha is not good enough for motor gasoline (mogas). This fuel cut contains mostly

pentanes and hexanes. Research octane number (RON) of light naphtha is around 70. Isomerization

of this constituent can improve its octane number, reaching a good MON without olefinic and

aromatics content.

Catalytic reforming is a chemical process used to convert petroleum refinery naphthas, typically having

low octane ratings, into high-octane liquid products called reformates which are components of high-

octane motor gasoline. Basically, the process re-arranges or re-structures the hydrocarbon molecules

in the naphtha feedstock into aromatic components as well as breaking some of the molecules into

smaller molecules. The overall effect is that the product reformate contains hydrocarbons with more

complex molecular shapes having higher octane values than the hydrocarbons in the naphtha

feedstock. In so doing, the process separates hydrogen atoms from the hydrocarbon molecules and

produces very significant amounts of byproduct hydrogen gas for use in a number of the other

processes involved in a modern petroleum refinery.

The aim of an HDS Unit is to pretreat the feed of the FCC Unit. It is similar to hydrotreating, but

operates on higher pressure and temperature. With the proper selection on HDS/MHC catalyst

moderate flexibility can be achieved in the refinerys product slate.

Two catalyst packages are available to choose from:

HDS catalyst: Removes significant amount of sulphur with low hydrocarbon conversion.

HDS/MHC catalyst: Removes significant amount of sulphur and converts a larger amount of heavy

components into more valuable light hydrocarbons, mainly gasoil.

*Both catalyst types lifetime is 2 years, after this period the catalyst has to be changed, otherwise the

unit stops operating. Catalysts have to be ordered a year prior to the change! The construction cost of

the newly built HDS/MHC unit involves a HDS catalyst, with which the unit can start its operation in the

first 2 years. You do not have to wait 2 years if you would like to change the catalyst, you can do that

each year but of course ordering has to be done one year prior to change too.

Total Investment Cost:

Before constructing the unit, you can choose among three maximum capacities. If necessary, the unit

can be revamped to higher capacity later in the game. Until the revamp is complete, the unit operates

at the original, lower capacity.

Fluid catalytic cracking (FCC) is a conversion process used in refineries. It is widely used to convert

the high molecular weight hydrocarbon fractions of crude oils to more valuable gasoline, olefinic gases

and other products.

The FCC process vaporizes and breaks the long-chain molecules of the high-boiling hydrocarbon

liquids into much shorter molecules by contacting the feedstock, at high temperature and moderate

pressure, with a fluidized powdered catalyst.

In effect, refineries use fluid catalytic cracking to correct the imbalance between the market demand

for gasoline and the excess of heavy, high boiling range products resulting from the distillation of crude

oil.

()Delayed coking is a thermal process in which the vacuum residue from crude distillation is converted

into lighter components and coke. The feed is heated in a furnace then confined in a reaction zone or

coke drum under proper operating conditions of temperature and pressure until the unvaporized

portion of the furnace effluent is converted to vapor and coke. Vapor is fractionated into different

products.

Hydrogen is required in refineries for hydrotreating processes, to remove sulfur, nitrogen and other

impurities from hydrotreater feed. A limited quantity of hydrogen is produced in the catalytic reforming

of naphthas, but generally the quantity is insufficient to meet the requirements of the refinery.

Hydrogen is produced by the steam reforming of natural gas, which is bought from the market or

consumed from the refinery fuel gas pool (simplification).

The throughput of HPP is always determined by the demand of hydrotreaters. If maximum capacity is

reached, excess hydrogen is automatically bought from the market.

Most crude oil contains varying amounts of sulfur. Hydrotreating various distillates from these crudes

generate hydrogen sulfide (H2S), which is converted to elemental sulfur in the Claus Unit to minimize

atmospheric pollution. In the absence of sulfur recovery, the only option would be to burn this gas in

refinery furnaces, releasing huge amounts of sulfur dioxide into the atmosphere. A new government

law will come into force in 2021 imposing a serious penalty on H2S burning: 30000 F$/t.

The throughput of the Claus Unit is always determined by the H2S production of the hydrotreaters.

The properties of blended gasolines are calculated from the weighted average of the blending

component properties. The calculation is volume based (in V/V%). Refinery splitters related to

Gasoline blending can be adjusted with 0.1% units with the help of little +/- signs next to the splitter for

finetuning the gasoline recipes to satisfy the strict specifications.

Example for calculation:

70%(V/V) FCC naphtha + 15%(V/V) Reformate + 15%(V/V) Isomerate

RON = 0.7 * 93.5 + 0.15 * 103 + 0.15 * 90 = 94.4
