Nexen Inc. (TSX, NYSE: NXY) today reported 2011 fourth quarter and annual operating and financial results, and provided a progress update on its strategic priorities for 2012.

In the fourth quarter, we generated cash flow from operations of $585 million ($1.11/share), reflecting a 12% increase in production over the third quarter to 208,000 boe/d (193,000 boe/d after royalties), and cash netbacks from oil and gas operations of $42.85/boe (after-tax).

Net income was $43 million ($0.08/share), reflecting one-time, after-tax charges of $190 million ($0.36/share) related to previous costs associated with our shift away from large, integrated upgrading projects in our future oil sands development strategy, and $127 million after-tax ($0.24/share) for impairments related to our gas assets in Canada and the United States, due to low gas prices.

For the full year, cash flow was $2.4 billion ($4.49/share), net income was $697 million ($1.32/share) and production averaged 207,000 boe/d (186,000 boe/d after royalties). Cash netbacks from oil and gas operations were $40.20/boe (after-tax) in 2011.

The annual results met our expectations for cash flow ($2.1-$2.8 billion) and our revised expectations for production (200,000-215,000 boe/d). Total 2011 capital expenditures of $2.6 billion were also within our expected range of $2.4-$2.7 billion.

"Nexen delivered solid results in the fourth quarter," said Kevin Reinhart, Nexen's interim President & CEO. "Production met expectations, Long Lake generated positive cash flow, and we entered into two joint ventures in the Gulf of Mexico and shale gas with strong partners.

"I'm pleased with the commitment our employees have made to delivering on our strategic priorities for 2012 and beyond," continued Reinhart. "2012 has started off strong. Long Lake production continues to grow and Buzzard is back to operating normally. We advanced our near term production growth projects including Usan, our UK tiebacks and Long Lake pads 12 and 13. We are also excited about our second drilling success on the Appomattox field in the Gulf of Mexico."

1.  Cash netback is defined as our corporate average cash netback from oil
    and gas operations, after-tax. 
2.  For reconciliation of this non-GAAP measure, see Cash Flow from
    Operations on pg. 13 
3.  Includes geological and geophysical expenditures. 
4.  Net debt is defined as long-term debt and short-term borrowings less
    cash and cash equivalents. 

Fourth quarter cash flow from operations increased 13% over the third quarter primarily due to increased production and our rising cash netbacks. Annual cash flow from operations was the highest since 2008 as our weighting to unhedged, Brent-priced oil allowed us to realize premium pricing throughout the year. Brent averaged US$111 in 2011; this represented a $16 premium to WTI.

Net income declined quarter-over-quarter and year-over-year as a result of several items. It reflects a one-time charge of $190 million (after-tax) related to changes in our future oil sands development strategy. Our original strategy was to build duplicates of the existing Long Lake SAGD facilities and upgrader. We now expect to pursue smaller, phased, SAGD-only projects and will consider adding upgrading capacity once we are bitumen-long and economic conditions are favourable. As a result, previously capitalized design and engineering work done on the future phases has been expensed.

Lower annual net income also reflects impairments, primarily on our gas assets, in the third and fourth quarters of 2011, and gains on the sale of our heavy oil properties which increased net income in the third quarter of 2010.

Net debt has declined 13% in the past year and 36% over the past two years based on the success of our non-core asset disposition program.

Fourth quarter production increased 12% over the third quarter, primarily due to higher production from Buzzard and Long Lake.

Reliability at Buzzard significantly improved following completion of the commissioning of the fourth platform; our production efficiency rate was 86%. For 2012, we are targeting 85% before planned shutdowns (78% including scheduled downtime).

In the North Sea, the Blackbird tieback to Ettrick came on-stream in November, seven weeks ahead of schedule, and is currently producing to expectations; production in the fourth quarter was approximately 5,000 boe/d (gross). Severe weather resulted in longer than expected downtime to complete the Telford TAC tieback, which was finished in early February.

Long Lake bitumen production averaged 31,500 bbls/d (gross). This represents a 7% increase over the third quarter as production from the first 11 pads continues to increase and facility turnarounds were completed in the third quarter. At Syncrude, production was lower as a result of unscheduled maintenance on a hydrogen plant.

Production in Yemen and the Gulf of Mexico continued to experience natural declines; Yemen production was further reduced with the expiry of our contract for the Masila block in mid-December.

1.  2010 includes production before royalties of 9 mboe/d and production
    after royalties of 7 mboe/d from discontinued operations. 

Production in 2011 was lower than 2010, primarily as a result of the sale of our heavy oil properties in the third quarter of 2010, natural declines, and production interruptions at Buzzard due to unplanned maintenance, third-party pipeline restrictions, and delays in commissioning the fourth platform.

We met our revised fourth quarter and annual production guidance.

Guidance Update

We are on track to achieve 2012 first quarter production guidance. Year-to-date production volumes are a little over 190,000 boe/d compared to our first quarter guidance range of 180,000-220,000 boe/d.

Buzzard has averaged approximately 185,000 boe/d (gross) so far this year, reflecting our operating efficiency of 85%. At Long Lake, bitumen production has increased to recent 7-day rates of approximately 35,000 bbls/d as pad 11 production continues to grow and we focus on production optimization from all wells.

At Long Lake, we have rescheduled the planned maintenance turnaround to take advantage of better labour availability. As a result, the three-week SAGD turnaround and six-week upgrader outage will now take place in the third quarter; they were previously scheduled for the second quarter. We have updated our second and third quarter guidance to reflect this change in timing.

Operational Update

Conventional

Offshore West Africa - Development of the Usan field remains on schedule; the project is our largest source of new production in 2012 and is expected to contribute to significantly stronger corporate cash netbacks this year. Final commissioning activities are in progress and first production is expected in the next month or two. Development activities were not affected by earlier civil unrest in Nigeria.

Usan's facility capacity is 36,000 bbls/d net to Nexen; actual production rates will vary based on well performance, pace of ramp-up and facility uptime.

"First production from Usan will be a major achievement," commented Reinhart. "The project is our newest legacy asset, and will generate significant cash flow for Nexen for many years. It also significantly strengthens our corporate netback, as the margin it generates is higher than our already strong corporate average."

We expect to drill an exploration well at Owowo West in 2012. This well is targeted to follow-up on our earlier success at Owowo South B.

UK North Sea - Following final regulatory approval of the Golden Eagle development early in the fourth quarter, we began work on the fabrication of the facilities, utilizing many of the same teams that oversaw the successful construction of the Buzzard platforms. The work is proceeding on-time and on-budget, and we expect first production in late 2014. The facility will have a capacity of 70,000 boe/d (26,000 boe/d net to Nexen).

We also continue to progress our tieback projects in the North Sea. Blackbird came on-stream through the Ettrick facility in November and is currently producing to expectations. Telford TAC came on-stream in February; Rochelle is proceeding as planned and first production is expected around the end of 2012.

We have an active UK exploration program planned, including the North Uist exploration well west of the Shetland Islands, where drilling is expected to begin late in the first quarter.

Gulf of Mexico - At Appomattox, we followed-up our successful 2010 exploration well in the south fault block with another success in the northeast fault block. The well encountered approximately 150 feet of net oil pay; we are currently completing an evaluation to determine the size of the discovery. Resource on the northeast block would be in addition to the 65 million boe of probable reserves we booked on the south block.

We plan to continue drilling at Appomattox with an appraisal well on the south fault block and a sidetrack into the northwest fault block to test the third major part of the Appomattox structure. We have a 20% interest in Appomattox, the remaining interest is held by Shell Offshore Inc., who is the operator.

At Kakuna, we expect to reach target depth around the end of the first quarter. We expect to drill our next operated exploration well in the Gulf, at Angel Fire, later this year.

Oil Sands

Long Lake - At Long Lake, our focus is on advancing the 60 additional wells to fill the upgrader.

In the fourth quarter, Long Lake showed strong progress. Total production increased 7% over the prior quarter to 31,500 bbls/d of gross bitumen at a steam oil ratio (SOR) of 4.8.

Upgrader yield (PSC(TM) barrels per barrel of bitumen) was 76% and facility on-stream time was 78%. Per barrel operating costs were lower than previous quarters, primarily due to the increased production and the higher yield.

These factors contributed to positive cash flow from operations of $22 million in the quarter and $5 million for the full year.

1. Unit operating costs and realized prices are based on PSC(TM) and bitumen volumes sold and exclude activities related to third-party bitumen purchased, processed and sold. Unit operating cost includes energy cost.

Over the past few weeks, production at Long Lake has increased to approximately 35,000 bbls/d. This reflects successful and ongoing well optimization initiatives and the growth in pad 11 production. Pad 11 is currently producing approximately 4,500 bbls/d and is continuing to ramp-up. The expected production range for this pad is 4,000 to 8,000 bbls/d.

We are making steady progress on our plans to fill the upgrader. Drilling has concluded on pads 12 and 13, and well completion activities are underway. We remain on track to begin steaming pad 12 in the spring; pad 13 is expected to follow sometime in the late summer or early fall. Production from both pads is expected before the end of the year. These pads specifically targeted higher-quality resource; our drilling results confirm that the resource quality is as we expected.

The regulatory approvals for pads 14, 15 and K1A are progressing. We are awaiting approvals for one or both projects this spring, which would enable us to begin drilling next winter. These wells have geological characteristics similar to our current best-producing wells.

In aggregate, we anticipate these wells will allow us to fill the upgrader over the next several years:


                                         Number of Wells      Expected Rates
                                                                      bbls/d

Pads 12 & 13                                          18     11,000 - 17,000
Pads 14 & 15                                       10-12       6,000 - 9,000
Kinosis K1A                                        25-30     15,000 - 25,000

"I am pleased with the progress we are making on our action plan to fill the upgrader," said Reinhart. "We continue to increase production from our existing wells, and are on track to bring on-stream additional wells in the high-quality resource areas."

We are also continuing work on a non-operated SAGD project at Hangingstone, of which we own 25%. The operator has delayed sanctioning of the project until late this year in order to complete the regulatory approval process. We expect the project to come on-stream in 2016 and our share of production at full rates will be about 6,000 bbls/d.

Shale Gas

Northeast British Columbia - We continued our strong execution on our Horn River shale gas program during the quarter. Our 9-well pad started up ahead of schedule and early production results are meeting expectations. Preliminary results indicate initial rates up to 18 mmcf/d per well. We are currently producing at our facility capacity of 50 mmcf/d.

Work continues on our 18-well pad and we remain on-time and on-budget. We anticipate production from this pad will begin in the fourth quarter, in conjunction with an increase in our facility capacity. This is expected to bring our total gross production capacity to 175 mmcf/d.

Our previously announced JV agreement with INPEX CORPORATION and JGC Corporation is expected to close in the second quarter 2012.

2011 Capital Investment and Reserves

In 2011, we invested $2.5 billion in oil and gas activities and added 73 million boe of proved reserves. These reserve additions replaced 96% of our production. On a proved plus probable basis, reserves increased 8%. Detailed tables outlining changes to reserves can be found on page 12 of this release.

The proved reserve additions relate primarily to the following areas:


--  Northeast British Columbia shale gas (30 million boe). 
--  Buzzard (15 million boe). 
--  Long Lake/Kinosis K1A (10 million boe), reflecting a reduction relating
    to the lower resource quality areas on Long Lake (84 million boe) more
    than offset by additions from the high-quality resource in the K1A area
    (94 million boe). 
--  Scott/Telford, including the Telford TAC tieback (9 million boe). 
--  Syncrude (8 million boe). 

We have 1 billion boe of proved reserves and 2.3 billion boe of proved plus probable reserves, representing reserve life indices of 13 years on a proved basis and 30 years on a proved plus probable basis. As previously disclosed, we also have a large inventory of attractive exploration prospects and billions of barrels of oil equivalent in contingent oil sands and shale gas resources. This provides a significant resource base for future growth.

Note to Investors on Reserves

The reserves estimates in this disclosure were prepared in February 2012 with an effective date of December 31, 2011. The estimates of reserves and future net revenue and have been internally prepared by an internal qualified reserves evaluator in accordance with National Instrument 51-101 Standards of Disclosure for Oil and Gas Activities ("NI 51-101") and the Canadian Oil and Gas Evaluation Handbook ("COGE Handbook"). Nexen's estimates of reserves prepared in accordance with SEC requirements are attached to its 2011 Annual Information Form.

Investors should note the following fundamental differences between reserves estimates and related disclosures prepared in accordance with NI 51-101 and those prepared in accordance with SEC requirements:


--  SEC reserves estimates are based upon different reserves definitions and
    are prepared in accordance with generally recognized industry practices
    in the U.S. whereas NI 51-101 reserves are based on definitions and
    standards promulgated by the COGE Handbook and generally recognized
    industry practices in Canada;
--  SEC reserves definitions differ from NI 51-101 in areas such as the use
    of reliable technology, areal extent around a drilled location,
    quantities below the lowest known oil and quantities across an undrilled
    fault block;
--  the SEC mandates disclosure of proved reserves and the Standardized
    Measure of Discounted Future Net Cash Flows and Changes Therein
    calculated using the year's monthly average prices and costs held
    constant whereas NI 51-101 requires disclosure of reserves and related
    future net revenues using forecast prices and costs;
--  the SEC mandates disclosure of reserves by geographic area whereas NI
    51-101 requires disclosure of reserves by additional categories and
    product types;
--  the SEC does not require the disclosure of future net revenue of proved
    and proved plus probable reserves using forecast pricing at various
    discount rates;
--  the SEC requires future development costs to be estimated using existing
    conditions held constant, whereas NI 51-101 requires estimation using
    forecast conditions;
--  the SEC does not require the validation of reserves estimates by
    independent qualified reserves evaluators or auditors, whereas, without
    an exemption noted below, NI 51-101 requires issuers to engage such
    evaluators or auditors to evaluate, audit or review reserves and related
    future net revenue attributable to those reserves; and
--  the SEC does not allow proved and probable reserves to be aggregated
    whereas NI 51-101 requires issuers to make such aggregation.

The foregoing is a general description of the principal differences only. The differences between SEC requirements and NI 51-101 may be material for certain properties. Please also note:


--  we use oil equivalents (boe) to express quantities of natural gas and
    crude oil in a common unit. A conversion ratio of 6 mcf of natural gas
    to 1 barrel of oil is used. Boe may be misleading, particularly if used
    in isolation. The conversion ratio is based on an energy equivalency
    conversion method primarily applicable at the burner tip and does not
    represent a value equivalency at the wellhead. Using the forecast prices
    applied to our reserves estimates, the boe conversion ratio based on
    wellhead value is approximately 30 mcf: 1 bbl; and
--  because reserves data are based on judgments regarding future events
    actual results will vary and the variations may be material. Variations
    as a result of future events are expected to be consistent with the fact
    that reserves are categorized according to the probability of their
    recovery.

Nexen has received an exemption from NI 51-101 that permits us to forego the requirement to have our NI 51-101 reserves and related future net revenue attributable to our reserves evaluated, audited or reviewed by an independent qualified reserves evaluator or auditor. Accordingly, our future net revenue and reserves estimates are based on internal evaluations. Due to the extent and expertise of our internal reserves evaluation resources, our staff's familiarity with our properties and the controls applied to the evaluation process, we believe the reliability of our internally generated reserves estimates is not materially less than would be generated by an independent reserves evaluator.

1.  Defined as cash flow from operating activities before changes in non-
    cash working capital and other. We evaluate our performance and that of
    our business segments based on earnings and cash flow from operations.
    Cash flow from operations is a non-GAAP term that represents cash
    generated from operating activities before changes in non-cash working
    capital and other. We consider it a key measure as it demonstrates our
    ability to generate the cash flow necessary to fund future growth
    through capital investment. Cash flow from operations may not be
    comparable with the calculation of similar measures for other companies.
