Charles D. Davidson, Noble Energy's Chairman and CEO, commented, “The strong first quarter was an excellent start to 2013 and positions us to deliver on full year expectations.  The Tamar project in Israel has begun production and is experiencing significant market demand with our primary customer already exercising an option for increased supply.  Our second major project for this year, Alen in Equatorial





---




Guinea, is on track for first production in the third quarter.  Domestically, the DJ Basin continues to set production records driven by our horizontal drilling program.  In addition, we continue with our exploration program and have several significant opportunities before us.”





VOLUMES AND PRICES


First quarter 2013 sales volumes from continuing operations averaged 245 MBoe/d, an increase of


9 percent compared to the first quarter 2012, after adjusting for assets divested in 2012.  Production volumes were 249 MBoe/d with the difference attributable to the timing of crude oil liftings in Equatorial Guinea.  The sales volume split for the quarter was 48 percent liquids, 24 percent international natural gas, and 28 percent U.S. natural gas.





U.S. volumes totaled 146 MBoe/d for the first quarter 2013, an increase of 23 percent compared to the same quarter last year excluding volumes from divested assets.  The increase was attributed to growth from the horizontal plays in the DJ Basin and Marcellus Shale, and from the Gulf of Mexico largely due to the addition of Galapagos.  Natural production declines affected the remaining non-core U.S. assets.





Sales volumes from international assets were 99 MBoe/d for the first quarter of 2013, a decrease of


6 percent compared to the first quarter of 2012, excluding volumes from discontinued operations in the UK.  The decrease was due to reduced sales volumes offshore Equatorial Guinea resulting from the scheduled underliftings of crude oil.





Crude oil prices in the U.S. and international averaged $95.70 and $111.42 per barrel respectively, each down approximately five percent versus the first quarter 2012.  Natural gas realizations in the U.S. averaged $3.31 per thousand cubic feet (Mcf), up 26 percent from the first quarter of 2012, and averaged $5.15 per Mcf in Israel.  Natural gas liquid pricing in the U.S. averaged $39.19 per barrel for the quarter and represented 41 percent of the Company's average U.S. crude oil realization.





OPERATING EXPENSES


Total production costs per barrel of oil equivalent (Boe), including lease operating expense (LOE), production and ad valorem taxes, and transportation were $8.45 per Boe, up 4 percent from the first quarter of 2012.  LOE and depreciation, depletion, and amortization (DD&A) per Boe were $5.28 and $16.53, respectively.  The DD&A rates were influenced primarily by increased liquids production from the DJ Basin and Gulf of Mexico, and the continued natural gas production from the Noa and Pinnacles fields offshore Israel.  General and administrative expenses increased during the first quarter due to increased staffing for major development and exploration activities.  The adjusted effective tax rate for the first quarter 2013 was 28 percent with 69 percent deferred.

OPERATIONS UPDATE


In the DJ Basin, production averaged 92 MBoe/d for the first quarter, a 7 percent increase over last quarter.  The horizontal program accounted for 45 MBoe/d of production compared to 39 MBoe/d last quarter.  Crude oil and other liquid sales rose to 63 percent of total production.  Adding a rig in the first quarter, the Company now operates three rigs in Northern Colorado and six in the greater Wattenberg area.  During the quarter, 56 wells were drilled and 44 wells were completed.  Ten of the wells drilled during the quarter were extended-reach lateral wells.  The extended-reach lateral program continues to deliver superior results and returns.  Currently, 13 wells are on line with lateral lengths ranging from 6,500 to over 9,000 feet.  Early production from the 15 wells in our 40-acre spacing pilot program indicates that production from the B bench performs as expected and does not appear to be impacted by tightly spaced A bench and Codell wells.  This result confirmed that a minimum of 16 wells per section is required throughout the Company's acreage in the oil window.  Wells in the A bench, C bench, and Codell indicate recoveries that are economic and will be required to adequately drain the entire 300 foot vertical section.





In the Marcellus Shale, the Company operated three rigs in the wet gas area and anticipates adding a fourth rig during the second quarter.  Two of the rigs were located in the Majorsville area and the final rig was in Normantown.  Drilling was concluded on the 11-well Web 4 pad and is expected to be in production by the end of the second quarter.  Other wells drilled include seven on the 11-well SHL 8 pad and four on the 7-well WFN 1 pad.  In Normantown, drilling operations were initiated on a 6-well pad.  Consol, the joint venture partner, operated two rigs in the dry gas area.  Production for the quarter averaged 104 MMcfe/d net.





In the Eastern Mediterranean, natural gas sales were initiated from the Tamar field in just over four years from discovery with a peak capacity of 1 Bcf/d.  Each of the five subsea wells was tested to its maximum deliverability of 250 MMcf/d.  Gross sales reached an hourly rate equivalent to 950 MMcf/d during testing.  The gross mean resource estimates were raised to 10 Tcf at Tamar and 18 Tcf at Leviathan resulting in 37 Tcf of total gross resources discovered in the Levant Basin.





UPDATED GUIDANCE


The full year volume guidance range for 2013 remains unchanged at 270 to 282 MBoe/d.  Second quarter 2013 volumes are expected to average 254 to 260 MBoe/d.  The increase in the second quarter volume forecast is largely attributable to a full quarter of production from Tamar.  Also impacting the quarter are planned facility downtimes in the Gulf of Mexico and Equatorial Guinea, adverse weather conditions in Colorado, and the sale of certain non-core assets, which in aggregate total approximately 12 MBoe/d.  Volumes for the second half of the year are anticipated to average around 300 MBoe/d with

initial production at Alen, additional sales from Tamar and the continued acceleration of activity in the DJ Basin and the Marcellus Shale wet gas area.





All other annual guidance ranges remain unchanged.

The Securities and Exchange Commission requires oil and gas companies, in their filings with the SEC, to disclose proved reserves that a company has demonstrated by actual production or conclusive formation tests to be economically and legally producible under existing economic and operating conditions. The SEC permits the optional disclosure of probable and possible reserves, however, we have not disclosed the Company's probable and possible reserves in our filings with the SEC. We use certain terms in this news release, such as "gross mean resource estimate". These estimates are by their nature more speculative than estimates of proved, probable and possible reserves and accordingly are subject to substantially greater risk of being actually realized. The SEC guidelines strictly prohibit us from including these estimates in filings with the SEC. Investors are urged to consider closely the disclosures and risk factors in our most recent annual report on Form 10-K and in other reports on file with the SEC, available from Noble Energy's offices or website, http://www.nobleenergyinc.com .

NOTE:Adjusted net income from continuing operations should not be considered a substitute for net income as reported in accordance with GAAP. Adjusted net income from continuing operations is provided for comparison to earnings forecasts prepared by analysts and other third parties. Our management believes, and certain investors may find, that adjusted net income from continuing operations is beneficial in evaluating our financial performance as it excludes the impact of significant non-cash items. We believe such measures can facilitate comparisons of operating performance between periods and with our peers. See Schedule 2: Summary Statement of Operations





[1]During the first quarter of 2013, we completed the sale of certain non-core onshore U.S. properties.


[2]The net tax effects of adjusting items for 2013 and 2012 are determined by applying the statutory tax rate to each adjusting item. Prior to first quarter 2013, the net tax effects were determined by calculating the tax provision for GAAP net income from continuing operations, which included the adjusting items, and comparing the results to the tax provision for adjusted earnings from continuing operations, which excluded the adjusting items. The difference in the tax provision calculations represented the tax impact of the adjusting items. The effect of our change in method for calculating the net tax effect was de minimis for all periods presented.

While discretionary cash flow from continuing operations is not a GAAP measure of financial performance, our management believes it is a useful tool for evaluating our overall financial performance. Among our management, research analysts, portfolio managers and investors, discretionary cash flow from continuing operations is broadly used as an indicator of a company’s ability to fund exploration and production activities and meet financial obligations. Discretionary cash flow from continuing operations is also commonly used as a basis to value and compare companies in the oil and gas industry.
