Part I An Overview Frequently overlooked, the midstream industry is
a critical link to turn raw natural gas into usableproducts.
Natural gas is comprised of two parts - a light gascomponent and a heavier liquids component. Thelight gas consists of methane, while the liquidsconsist of ethane, propane, n-butane, iso-butaneand natural gasoline. These natural gas liquids(NGLs) are used in the petrochemical industry, asrefinery blend-stock, in home heating, and inmany other common applications.
Most wellhead gas does not meet the qualitystandards required by interstate pipelines, so itmust be processed, removing contaminates andthe heavier components (propane+).
After the NGLs and contaminants are removed,whats left is marketable gas (or dry gas),consisting of methane with some ethane. Thatgas is then ready to be delivered to interstate gaspipelines.
The raw NGLs are then sent to large fractionators
to break the stream into usable components(ethane, propane, etc.).

NGL Removal is Non-Discretionary
The typical NGL barrel looks like this: We stress: propanes and heavier components(propanes+), make up ~60% of the NGL stream, andhave to come out of the wet gas produced from the
wellhead. Pipeline specs mandate it. Ethane is discretionary, meaning
producers/processors can opt to keep it in thestream or remove it, depending on economics.
Keeping ethane in the steam is called ethanerejection (we know, it is the opposite of what isintuitive, but think of it from the processors
standpoint). The amount of Btus is always thesame - its just the state of matter thats different.
Ethane rejection = more gas, fewer NGLs
Normal processing = less gas, more NGLs10% Isobutane
25-30% Propane
40-45% Ethane
5-10% Normal Butane
10-15% Natural Gasoline

There are lots of ways to make moneythrough the midstream value chain.While most are fee-based, processing is
usually commodity sensitive.
Since processing involves convertingMMBtus from a gaseous form to a comboof liquids and gas, non fee-basedprocessing economics are dictated by thespread between the price of gas and the
price of NGLs (the frac spread).
Low gas prices/High NGL prices =Favorable processing economics(Btus worth more taken out of gas stream)
High gas prices/Low NGL prices =Unfavorable processing economics(Btus worth more in gaseous form)

Frac spreads, like refiners crackspreads or power producers sparkspreads, are a measure of gross margin.It is the delta between the cost of gas
(processing input) and its value in NGLform (processing output).
Frac spread = NGL Value Cost of Gas
These spreads are an industrybellweather when watching processingeconomics.
If frac spreads are positive, the MMBtusare more valuable in NGL form. Ifspreads are negative, the MMBtus aremore valuable in gaseous form.

Ethane Production Monthly Average Frac Spread
If frac spreads go negative,processors will reject ethane (~35-
45% of stream) keeping it in thegas.
Gas supply then increases, gasprices go down, feedstock becomescheaper, and markets correct.
If frac spreads go negative, mostprocessors have conditioninglanguage, which allows them to atleast cover costs.

Major U.S. Gas Processors The table to the left shows the major U.S. gas
processors. Gas processing represents only onesegment of the midstream value chain.
E&P companies used to be the primary ownersof gas processing plants, in order to supporttheir E&P operations. In the 1990s, companiesbegan selling off midstream assets to focus ontheir core E&P business.
The industry consolidated further as puremidstream plays developed. In 2008, thetop ten gas processors held two-thirds of U.S.processing capacity (excluding Alaska).
MLPs now dominate the space, as midstreamearnings are perceived to provide a certaindegree of stable, reliable cash flows,especially when exposure to the frac spread isminimized.

Gas processors describe natural gasas rich (wet) or lean (dry),depending on the amount of heavyrecoverable components contained.
A very rich gas may contain 5-6gallons of recoverable liquids permcf (gpm). A lean gas usuallycontains 1 gpm or less.
Deepwater Gulf of Mexico (GoM) gascan have 4+ gpm, compared with 1-1.5 gpm for the GoM shelf and 2-3gpm on the Texas Gulf Coast. WestTexas gas is also very rich.
Coal bed methane gas is essentiallyfree of NGLs and is comprised of onlymethane, water and sometimes CO2.

Processing Plants Follow Major Producing Areas
Source: EIA/DOE
U.S. Gas Processing Plants There were 539 gas processing plants and32 fractionators operating in the U.S. as ofJanuary 1st, 2008.
About 33% of U.S. gas processing capacity islocated along the Gulf Coast. But the bulkof new adds are planned for the Rockies(currently 11% of capacity) and Ark/La/TX(20% of current capacity).
About 80-85% of fractionation takes place
along the Gulf Coast; the NGLs areproduced close to the primary end-users petrochemical companies.
The average gas processing plant is gettinglarger and more efficient.

Getting NGLs to Market
Source: Canadian NEB, edited for changing ownership & new pipelines proposed
There are 2 major U.S NGLtrading hubs and 2 Canadianhubs: Mont Belvieu, TX;Conway, KS; Edmonton/FortSaskatchewan, Alberta; and
Sarnia, Ontario. NGL pipelines transport NGLs
from producing fields to thesehubs, where they are stored,fractionated, and/or distributedfor end use.
Mont Belvieu, the largest ofthese hubs, is located on theTexas Gulf Coast where there isthe highest concentration ofpetrochemical, storage,pipeline, fractionation, andrefinery infrastructure.
Given its strategic location,Mont Belvieu is considered theprice setter for North AmericanNGL markets.

Part II Summary and Historic Trends
The first section of this primer discussed four drivers of Midstream profitability:
U.S. gas production
NGL supply
NGL demand
Relationship between price of gas, crude oil, and NGLs
This section reviews the historic trends of each of these drivers. With the recent collapse in commodity prices andeconomic conditions, everything has been turned on its head. While historic trends arent always indicative ofwhere things are headed, the perspective should be helpful. Part III of this primer (p. 25) tackles where we thinkthings are headed.
In the meantime, a brief summary of historical trends:
U.S. gas production: On the rise, +9% ytd after years of stagnant production. But, rig count is falling (andwith it, we hope, production).
NGL supply: Also on the rise, albeit at a slower pace than gas production as NGL yields have fallen(movement to leaner onshore gas production from richer offshore).
NGL demand: Until quite recently, on the rise amid strong worldwide economies and a weak U.S. dollar.Recentlyin the tank.
Relationship between gas, crude oil and NGLs: Midstream economics are most favorable when gas trades ata discount to crude oil on a mmbtu basis and when NGLs trade at a high percent of crude oil price.Historically NGLs have traded at 65-70% of crude oil, but the recent economic turmoil has pushed NGLsdown to ~45% of crude oil. Historically natural gas has traded at a 6:1 ratio (crude:gas). Over the pastcouple of years, with the spike in crude, that ratio expanded to as high as 14:1. With the recent decline incrude, the ratio is back to ~10:1.

Since early 2001, U.S. gas production is+0.2%/yr on average.
During the same period, NGL
production is -0.9%/yr on average. The slower pace of growth of NGLs is
due to periods of ethane rejection(ethane kept in gas stream, resulting inless NGLs processed out) as well aslower NGL yields (leaner gas).
More recently, with the surge in U.S.
drilling, natural gas production is +9.0%while NGL production is +5.2% (year-to-date vs. 07).

Ethylene is the simplest alkene and the most widely produced organic compound in the world. 97% ofethane is used for ethylene production.
About 50% of ethylene is polymerized into polyethylene. This polymer is used most commonly to formlightweight packaging products (i.e. shopping bags) from low-density polyethylene (LDPE) and as a mediumfor injection molding (to make products like plastic containers) from high-density polyethylene (HDPE).

This polymer is most commonly used as a medium forinjection molding (for plastic products like containers) and in the fibers market (i.e. carpeting, textiles).
Propane demand has two seasonal offsets. Residential/commercial demand (40% of total) peaks during the winterheating season and troughs in the summer. Petrochemical demand (49%) peaks during the summer when propaneprices are lower, as the petrochemical industry switches between feedstocks depending upon price.

Ideally, we would have outlinedethylene and propyleneconsumption, but we just couldntfind any good source (if you haveone, please tell us!) However, we
feel that chemical rail car loadingsare a good proxy for petrochemdemand/NGL demand.
2007 and 2008 saw a big pick-up inloadings, driven by strong world-wide economies and a weak U.S.dollar.
The sharp fall-off in 2H08 reflectsthe immediate impact of HurricaneIke, which slammed into the heart ofpart of the Gulf Coast petrochemicalsector. But more than a monthlater, railcar loadings are still at 10-year lows as a weak economy takesits toll.

NGL Composite (% C rude) WTI ($/Bbl)
From a price standpoint, midstream economics aredictated by 2 key factors: 1) the relationshipbetween crude oil and natural gas; and 2) theprice of NGLs relative to crude oil.
The crude oil/gas relationship is importantbecause gas needs to trade at a discount tocrude/NGLs in order to have an economic
incentive to convert the btus from a gaseous formto a liquid form. Generally, crude forms theceiling while natural gas forms the floor.
Processing economics have directionally improvedover the past 10 years, as crude traded at higherand higher premiums to nat gas.
NGL prices are mainly influenced by the price ofcrude oil, as NGL feedstocks compete mostdirectly with crude oil-based feedstocks such as
naphtha and heating oil. NGLs trade near parity with oil on a heat content,
or Btu basis. However, on a volume basis, theyhave historically traded at about 65-70% of crudeoil.
More recently, with the decline in crude oil pricesand softening chemical demand, NGLs have tradedat closer to 45% of crude oil on a volumetric basis.
Part of the reason for the declining relationshipbetween NGLs and crude oil is that NGLs arealmost purely a physical commodity influenced byend-user supply/demand. Crude is influencedmuch more significantly by financial markets.

Ethane/Crude The Critical NGL Component
Since ethane is the largest component ofthe NGL stream and is the onlydiscretionary NGL, its price andrelationship to crude is the most volatileand closely watched.
The ethane market is domestic, with verylittle storage (30mmbbls or ~40 days ofsupply). Most ethane is used real-time inthe petrochemical industry, so pricesreflect real demand.

Part III What is Changing?
What a difference a few months make! This summer, the midstream industry was experiencing record frac spreads,rig count was at record highs, and massive investment was planned to increase ethylene and propylene capacity.
There was mounting concern that the U.S. would not be able to absorb the incremental ethane coming on as aresult of the surge in drilling and de-bottlenecking of NGLs via new pipelines. But there were also a number ofpetrochemicals looking to expand, driven by a weak U.S. dollar and strong worldwide economies.
Slam on the brakes and put it in reverse. Fracs spreads have fallen from $10+ to negative; ethane is trading at 25%of crude and NGLs 45%; petrochemical plants are idling across the globe; ethylene prices have fallen belowUS$350/MT in Asia from highs of US$1,650 this summer; and while we havent seen it in scale yet, we expect to seemajor projects cancelled/postponed. Its about as ugly as it gets.
Fortunately, as we discussed earlier, this business is cyclical, which means rig count/gas production will fall.Processors will reject ethane. Ethane, ethlyene and propylene inventories will fall. And well start the up cycleagain.
This downcycle may last a little longer than others because of the potential depth of this recession and the amountof new NGLs coming online the result of both higher production and NGL debottlenecking due to the completion of
NGL take-away pipelines.
As a result, for our Midstream companies, for the next couple of years we are modeling that NGLs trade at ~50% ofcrude oil (vs. historic 65-70% and 45% currently).
When we first looked at the amount of new ethylene and propylene capacity coming online, it was worrisome (39%increase if everything done, but almost all outside the U.S.). Were now assuming that only plants currently underconstruction are completed, resulting in 3.5%/yr average growth in ethylene/propylene capacity worldwide through2012.

Source: Canadian NEB, edited for changing ownership & new pipelines proposed
The U.S. NGL system has been, and willbe, further de-bottlenecked via the
completion of several key NGLpipelines.
EPDs MAPL line was completed earlier
this year and OKS Overland Pass linebegan ramping up in early October.Arbuckle (also OKS) should becompleted by Q109.
All the pipes wont be full from the
beginning. Overland Pass will somewhatcannibalize MAPL, but that simply
relieves MAPLs fully utilized facility.
All told, these pipelines have thecapacity to allow an increase in NGL
supply by 18%.
Further expansion is possible. OKS hasbeen planning to expand Overland Pass
by 145,000 bpd by 2010, but we wouldnot be surprised to see that pushed outa little. Arbuckle is expandable by50,000 bpd with additional pump

Changing Dynamics: Ethylene & Propylene
Currently, the U.S. has the most ethyleneand propylene processing capacity in theworld, at 22% and 27%, respectively. China
is second, with 8% of both ethylene andpropylene capacity.
Prior to the financial meltdown, there wasmounting concern that a massive amount ofplanned new international ethylene andpropylene capacity would flood the market,eventually resulting in the U.S. becoming anet importer, thus backing off demand for
domestic NGLs. The vast majority of the adds are in the
Middle East, where theyll use cheap gas tomake NGLs to feed the new petrochemicalplants.
Given the economic slowdown, we are nowassuming that only the plants currentlyunder construction will be built. In total,these add 15% to existing capacity, or3.5%/yr growth not helpful in a weakeconomy, but not the onerous 39% additionif everything was built.

NGL Supply Outlook
There are two ways to look at NGL supply domestically and on a global basis
In the U.S., while gas production is +9% year-to-date, NGL production is up a more modest 5%.Going back to 2001, the trend has been declining
NGL production as the overall gas stream becomesdrier. We think the recent surge in NGLproduction is driven, in part, by incredible NGLprocessing economics, which incent companies tomaximize NGL extraction. More recent processingeconomics (negative-to-breakeven frac spreads)should stem the rate of NGL production growth.
On a global basis, NGL production is clearly on therise, growing at a CAGR of 5% since 2000
(excluding North America) and 3% including NorthAmerica. Going forward, most of the incrementalproduction is destined for in-country use, primarilypetrochemical, to feed new plants.
The risk to the U.S. NGL industry is over-buildingof worldwide ethylene and propylene plants,resulting in cheap exports, and a decline in theU.S. petrochemical industry. With the recenteconomic meltdown, the risk of overbuilding hasbeen greatly reduced.

There are four primarysegments within the Midstreambusiness:
1. Gathering transports andoften compresses naturalgas and removes water andother contaminants;
2. Processing extracts NGLs,resulting in dry/marketable
natural gas and a raw NGLstream
3. Fractionation splits rawNGLs into finished product

Step 1: Gas Gathering
Gas gathering systems simply transports gasfrom the well-head to the processingfacilities.
Gathering lines typically operate at relativelylow pressures (just below wellhead pressure)and utilize pipe diameters of less of than12. Lower pressure systems reduce theneed to install field compression andgenerally allow for greater production.
At this stage, the gas is usually treated toremove natural gas condensates, water andother contaminants to prevent thecomponents from obstructing flow in ordestroying the integrity of the gatheringsystem. Small-scale gas-oil separators,condensate separators, and dehydration units
are typical treating equipment.

Step 2: Plant Processing
Plant processing takes wet gas from the fieldand removes the heavier, more liquidcomponents (NGLs) and other contaminants(water, hydrogen sulfide, etc) to create
marketable gas also known as dry orpipeline quality gas.
For safety and integrity reasons, pipelinesimpose restrictions on the composition of gasallowed to enter the line. Gas composition ismeasured in terms of dew point (the
temperature at which vaporized liquid willcondense at pipeline pressure) and the heat, orBTU content of the gas. A higher BTU contentmeans more liquids in the stream.
Processing economics depend, in part, on theprice of the liquids removed vs. their equivalent
BTU content if left in the original gas. Thedifference between the price of the liquidsremoved vs. their value in gaseous form iscalled a frac spread.

Fractionation is the process ofturning the raw NGL stream intomarketable products.
One-by-one, the hydrocarbons areboiled off, moving lightest (ethane)to heaviest (natural gasolines).
Fractionators are much larger scalethan gas processing plants, handlingthe output from multiple processing
plants. They are usually locatedclose to the petrochemical end-users.
Raw NGL pipelines transport NGLsfrom processing plants tofractionators. Finished NGLs

NGL marketers match up sellers (E&P andMidstream companies) with buyers petrochemicals, industrials, farmers, propanecompanies, etc.
Services include NGL transportation, storageand risk management services.
NGL marketing is primarily a physical business,with limited liquidity on financial hedging ofindividual NGL components much beyond 6-12months. Beware companies with dirtyhedges NYMEX crude as proxy for regional

Gas Processing: Three Major Contract Structures
Keepwhole (KH)
St ructure: Processorcompensates (keeps whole)the producer for the amount ofgas removed from theprocessing stream. Processorgets paid in NGLs, but
compensates producer basedon gas prices.
Commodit y Exposure: LongNGLs, short gas. So twosources of exposure relativegas/NGL prices and absoluteNGL prices.
Volati l i ty: High. Frac spreads
can and do move wildly andseasonally. Becausemidstream assets are heldmore by MLPs who do not likethat exposure, the trend hasbeen to negotiate away fromkeep whole contracts and toinsert, conditioning language,which provides minimum feesif fracs go negative.
Percent of Proceeds (POP)
St ructure: Processor is paid byretaining a percent of theoutlet stream, either NGLs,gas or a combination.
Commodit y Exposure: Long
liquids and/or natural gas,depending on contractstructure.
Volati l i ty: Moderate. Highercommodity prices = higher POPproceeds.
Fee-Based
St ruct ure: Fixed fee, eithervolumetric or a demandpayment.
Commodit y Exposure: None.
Volati l i ty: If volumetricpayment, only volatility isthroughput based.
Keepwhole Margin =
NGLs Removed (MMBtu) x FracSpread ($/MMBtu)
Percent of Proceeds Margin =
[NGLs Removed (MMBtu) xNGL Price ($/MMBtu) x % ofNGLs Retained] +[Gas Remaining (MMBtu) xGas Price ($/MMBtu) x % of GasRetained]

Step 1: Calculate the NGL value ($/MMBtu). Multiply component prices bythe heat content and composition of the gas. Frac spread is the difference
between the value of theprocessed NGLs and the value ofthe equivalent btus of gas inputinto the processing plant.
Frac spreads are negatively
correlated with gas prices (gasgoes up, fracs go down) andpositively correlated with NGLprices (NGLs go up, fracs go up).
Frac spreads are volatile andusually seasonal narrowing withhigher gas prices during thewinter.

Appendix Midstream Terminology
Conditioning mode Processing mode when NGL economics are unfavorable whereby the processor removesonly the minimal amount of NGLs, saving on fuel and other operating expenses. Most keep whole contractsnow contain conditioning language in the event frac spreads go negative.
Ethane rejection mode Process of keeping ethane in the gas stream (rejecting it from processing) becauseeconomics dictate the btus will receive a higher price for gas than liquids.
Fee Based Midstream contract gathering, processing, fractionation, etc. where services are conducted ona fee/unit basis.
Frac spread - Value of natural gas liquids after they are processed out of natural gas, in excess of the price ofthe gas itself (i.e. gross margin on NGLs).
Fractionation process of splitting the raw NGLs into marketable products.
Keepwhole Contract type whereby processor keeps 100% of the liquids and keeps the producer whole bycompensating them for the btus on a gas-equivalent basis.
Naphtha - a distillation product from petroleum or coal tar containing certain hydrocarbons. Naphtha is usedprimarily as feedstock for producing a high octane gasoline component (via catalytic reforming). It is also usedin the petrochemical industry to produce olefins in steam crackers and in the chemical industry for solvent(cleaning) applications.
Natural gas condensate Output of the processing of wellhead gas.
NGLs (Natural Gas Liquids) Portions of natural gas that are liquefied via gas processing. They include ethane,
propane, butane, and natural gasoline. NGL shrink Reduction in gas available for sale as a result of removing NGLs from the gas stream.
Percent of proceeds Processing contract where processor receives a percent of the outlet stream eithergas, NGLs, or a combination.
