Key Messages

NYSE: DVN www.devonenergy.com

a. Different operators have different philosophies, e.g. exhaustivestudies before sanction, OR, less study and adjust as well results are seen.

b. It’s all about eye on the prize, risks and NPV!

c. GoM Ultra Deep Water (UDW) stretches drillers and calls for field development strategies like never before;

d. Increasing lag, UDW discovery to development;

e. One more time: the easy oil has been found!

f. Hubs & spoke tradition may continue, export a bigger consideration than before;

g. FPSOs different for today’s GoM, more of them possible, flexibility critical.

www.devonenergy.com 4 of 55

Today’s Agenda

1. Focus on production from remote prospects;

2. High stakes frontier: extreme physical, risk and financial challenges;

3. Highly prospective but risks slow sanction;

4. Huge drilling investments affecting facility choice;

5. Export issues – the coming shootout: pipelines and shuttle tankers;

6. Projecting what lies ahead for FPSOs in UDW GoM.

History in GoM

MMS/USCG approval in principle achieved in Record of Decision in December 2001 for FPSOs and shuttle tankers in US waters;

For service in US waters FPSOs can be built anywhere. In contrastshuttle tankers must be owned, built and crewed in US;

For the record, the first two FPSOs in GoM were in Mexican waters:1st FPSO 1989 Owned by Pemex1st FSO 1998 Charter from Modec2nd FPSO 2007 Charter from BW Offshore

Third FPSO in GoM - and first on US side - was contracted in 2007 toenter service in 2010.

Industry Pressures

• The US government for about two years has seen the slowdown in translating discoveries into booked reserves and royalty producing production;

• The industry sees the slow down too – planning is difficult, cannot take these risks without exhaustive work, witness Jack St. Malo;

• The US public presses for reduction of dependence on foreign oil(witness the election!);

• Devon like many operators in GoM has used various types of floaters in the past in different parts of the world;

• For the development choice to be an FPSO for GoM it has to be proven the optimum business choice.

Devon is an Independent on Facility & Transportation

• Devon is an E&P company, i.e. has no refineries to feed;

• Devon owns neither an offshore pipeline company nor a shipping company;

• Every incentive therefore exists to objectively seek out the most cost efficient facility & transportation solution for Devon’s prospective developments in the ultra deep remote waters of the GoM!

• Rigorous internal debate, little/no bias pro/con FPSOs & shuttle tankers;

• Concept selection process slow and deliberate with Devon and itsPartners.

NYSE: DVN www.devonenergy.com

Stating the Obvious?

• Some may feel GoM is prejudiced against FPSOs;

• But just like the rest of the world, the production solution is tailored to suit profitable production of oil and gas!

• Just happens to be difficult to arrive at the right economic technical and minimal risk choice in GoM for Lower Tertiary;

• Takes an unusually intense and protracted decision making process!!!

• Framing of Development Options: Characterizing risks & uncertainties for “Difficult-to-Choose” options to lead to THE development option, so the TEAM, as a group, can:

– Clearly defines the decision problem;– Choose the options they would like to consider, and– Establish the means and measures (metrics i.e. ROR, NPV, etc)

they will consider when it comes time to make that choice.

• Reveals the sensitivities of the different options to the risks and uncertainties characterized above;

• Understanding & quantifying the impact of “More Information” (VOI – Value of Information exercise). Results not always intuitive!

• Same practical reasons hold today, looking ahead, may see sharedfacilities, profit motive for all;

• FSOG: Devon developed concept for hub storage in remote ultra deep waters of Walker Ridge and Keathley Canyon, ability to collect and process gas on deck;

• FPSO: Ability to serve as a hub may be a priority in FPSO capabilities, similar to FSOG.

Separate fields using Devon operated FSOG with shuttle tankers to Gulf Coast refineries: typically use a standard VLCC with 2,000,000 bbl storage capacity US patent pending, inventors:

Dave Bozeman & Steve Seat

Capacity 300,000 – 500,000 bopd

www.devonenergy.com 38 of 55

Features of the FSOG

• Common infrastructure for storage and transportation of crude;

• Provides for collection, processing & compression of commercialgas volumes in low GOR region;

• Provides marketing hub for tie in of future fields;

• Devon has a patent pending for the FSOG: “Method and System for Gathering, Transporting and Marketing of Offshore Oil and Gas”;

• Practically: FSOG is an assembly of proven components: double hull VLCC, low pressure risers, disconnectable turret mooring;

• Could work with any non disconnectable option (e.g. spar etc.);

• Would mean an extra tariff to add to the shuttle tanker tariff.

GoM Export: Factors to be WeighedInfluence of pipe or tanker on facility choice

1 Quality Bank Can exist in pipelines on shorter term and be of similar magintude as transportation tariff.. Unknown is its potential for the Lower Tertiary grades of crude in entering common carrier pipeline segments over the life of field. Objective: determine a $/bbl indication for QB over LOF

2 Optionality Weighing of risks of "2005 all over again" and what to do about it so major loss of revenue risk is mitigated, e.g. six (6) or more months loss of production. Determination of optionality necessary to achieve an accceptable risk, e.g. is 2 pipeline destinations from SS 332 adequate? What consequent costs may be involved in assuring this?

3 Upside on marketing to a wider range of destinations

A determination of the possible enhanced margin from being able to deliver to many more destinations via tankers over the life of the field, e.g. a projection of probable increase in margin, $/bbl

4 Guaranteed future access throughout field life

Determination that it is feasible to have a pipeline contract for the life of field with no risk of curtailment of capacity by pipeline owner or any regulator at some future date.

5 Determining the preferred development solution for LT

Establishing the practical need in field development solutions for storage or not, weighing viability of a regional storage hub, i.e. influence of the development option on export system. Attempts are underway to isolate the Transportation choice from the field development choice.

More on GoM Export FactorsGets complicated and controversial!

6 Making a start on discussions with pipeline and tanker providers

Experience indicates the cycle time from expression of interest to firm contract may be long and arduous for a remote ultra deepwater export system for a precedent breaking system like this. Desirable to shorten this to fit probable development plans for Devon to "accelerate through the value chain".

7 Reconcile conflicting pipeline indications

Available documents from contractor inputs indicate a larger range on economics. Are volumes, terms, commitments comparable? Is one more willing to absorb more risk upfront than the other?

8 Make production profiles practical

Drillling may take five years so the production profile may be spread out more than the ideal from our reservoir calculations: how does this affect our economics, plans and risks for export?

9 Sensitivities to changes in volumes as production proceeds

Oilfields rarely produce exactly as the production profiles here predict! Changes are likely, up or down, and forward or backward in time. Means of dealing with this are desired.

10 Other key risks, commercial considerations identifed by contractors

Examples may be delivery schedules for tankers, long lead item commitments, other risks Devon had not thought of.

NYSE: DVN www.devonenergy.com

Arriving at Economic Projections for Both Export Modes: Needs Care!

Factor Economic Projection Explanation

Transportation Tariff

Firm: generally set at transportation

contract time

Total transportation cost from production flange on platform cellar deck to the refinery's storage tank. Needs to allow for ALL export system components, e.g. multiple segments (new and existing) for pipeline delivery, export pumps and riser or hose system costs on the producing platform, platform space and services contributions

Quality Bank Fuzzy: may change with time over LOF

Loss of value when one grade of crude is commingled with a common stream in a pipeline. A poorer grade means a deduct and then the higher quality stream leaving the pipeline means an adder. However the deduct is usually seriously more than the adder, meaning a net cost element in the overall transportation economics!

Reliability Optionality

Fuzzy: management's best

calculation

The value of being able to redirect production from one destination to another in the event of hurricane or other damage. Well known examples would be the BP Texas City Refinery explosion - or the damage suffered in various pipelines and shore stations after the Katrina and Rita hurricanes in 2005

Market Optionality Fuzzy: can vary with time

The value to a producer of being able to play the market in selling its production, whether by pipelines to multiple sales points or via tankers that can be redirected at will to different ports for sale.

Key factors in weighing transportation economics: the fuzzy components can easily add up to be as large or larger than the the firm component!

A Sound Business Case Does Exist for FPSOs & Shuttle Tankers

• Shuttle tankers may indeed offer an economic benefit over pipelines for a large field in the Lower Tertiary: could amount to about a $Billion saving over field life;

• Aggregation of large enough volumes to enable an economic pipeline is more difficult in Lower Tertiary than closer to shore. Very difficult indeed for early production. Risks and economicscan favor tankers;

• Tankers offer future flexibility in changing destinations for maximum margin from production - and in event of hurricane damage can be directed to alternate delivery points;

• In the event of a field being a bust, tankers being redeployablemitigate risk on export service commitments. Pipelines are not good at being reeled up and redeployed!

6. Projecting what May Lie Aheadfor FPSOs in UDW GoM

Compared to a year ago, it’s starting to come into focus

www.devonenergy.com 45 of 55

Early Well Testing (EWT) ? And/or Early Production Systems (EPS) ?

• Gas cannot be flared in GoM – makes shorter term operations more difficult than in countries where there is some regulatory latitude for trials in new areas;

• Desirable to test wells for longer durations but assembling the spread is difficult and costly ;

• Smaller shorter term EPS, possibly on DP, has been debated in GoM but true added value to a field development often not there - or not conclusive;

• Dilemma of equipment being built if several multi-month (or one or two year) long commitments were available. The trick is stitching together enough of these to enable vessel construction;

• In spite of much discussion, no definitive EWT solution for GoMyet selected!

NYSE: DVN www.devonenergy.com

www.devonenergy.com 46 of 55

Is There Really a Case for an FPSOfor Full Field Development?

• Simultaneous with reserves that are deeper, higher pressured, more remote, requiring bigger CAPEX, the corporate need in these megaprojects intensifies to maintain capital discipline and project management discipline;

• So we could study it to death to mitigate risks - or take some risks with future flexibility at a premium;

• How to forge ahead? How to apply Devon’s mantra “accelerate through the value chain”?

• More GOM acceptance of FPSOs: the rise of the independents, plus arrival of serious non GoM experience (Petrobras, StatoilHydro);

• Conclusion: Circumstances now more favorable today for FPSOs in GoM than before, if they can be more flexible in capability & business basis;

NYSE: DVN www.devonenergy.com

Putting it Together . . .Devon’s Perspective (1 of 3)

a. For locations a long way out, over mountainous seabeds, pipeline routes much longer, more circuitous and more expensive than hitherto. Export economics thus may favor FPSOs;

b. Pressure to cut the cycle time to improve economics is counteredby risks of reservoirs performing differently from expectations;

c. Corporate goals of large independents may favor FPSOs: proving as they go along, e.g. EPS morphing into FFD;

d. Commitments on export pipelines are huge, tanker export easier to start quickly for remote areas and grow incrementally – again export system selection may favor FPSOs;

e. Drilling, well access, available technologies affect facility choice (e.g. dry trees and/or DVA, hence no FPSO);

f. Not conclusive that there must be a future for FPSOs for FFD in ultra deep in GoM;

NYSE: DVN www.devonenergy.com

www.devonenergy.com 48 of 55

Putting it Together . . .Devon’s Perspective (2 of 3)

g. Logic of Real Option Value decision process expedites steering acourse in uncertain waters (pun intended);

h. Rigorous internal debate, little/no bias pro/con FPSOs;

i. No export legacy of pipeline operation, shuttle tanker v. pipeline, relatively open competition;

j. Concept selection process slow and deliberate with Devon and itspartners;

k. Projecting the future fleet size of FPSOs for US GoM would require truly remarkable use of crystal balls on a biblical scale!!!

l. Would not expect a flood of FPSO orders for GoM.

Putting it Together . . .Devon’s Perspective (3 of 3)

m. For Devon’s 2008 portfolio of Lower Tertiary prospects in the UDW GoM, we can confirm considering FPSOs along the lines of:Technically: + EPS expandable to FFD

+ Suezmax newbuild;+ Disconnectable;

Commercially: + Studies on FPSOs for GoM underway;+ Early talks with contractors;+ Firm commitment dependent on well results;+ Premium on flexibility and speed;+ Bid process could proceed – or negotiation on hull

under construction – depending on progress;+ Linked to availability of shuttle tankers.

n. We do encourage exchange of ideas with contractors, expect them to make a reasonable profit, and understand paying for successful performance!
