Highlights

·                  Third quarter 2017 net production significantly exceeded guidance expectations.

·                  Domestic net production was 159,000 BOEPD (41% oil and 64% liquids), exceeding the mid-point guidance by approximately 4,650 BOEPD. The better than expected results during the quarter were primarily related to higher volumes in STACK.

·                  Consolidated net production was approximately 161,700 BOEPD (42% oil and 64% liquids). In China, the Company lifted approximately 239,000 barrels of remaining oil from the damaged storage vessel during the quarter. Oil liftings in China are expected to resume in the first half of 2018 following repairs to the third-party storage vessel.

·                  Newfield’s Anadarko Basin production increased approximately 20% quarter-over-quarter (3Q17 vs 2Q17), averaging approximately 105,000 BOEPD during the third quarter. The Anadarko Basin now comprises approximately two-thirds of total domestic production.

·                  Anadarko Basin net oil production grew more than 25% quarter-over-quarter (3Q17 vs 2Q17) to achieve a record average quarterly output of 37,000 BOPD.

·                  Based on state records, Newfield is now the largest gross oil producer in the State of Oklahoma.

·                  Realized oil prices in STACK continue to improve, averaging $48.04 per barrel, or approximately 99% of NYMEX WTI during the quarter.

·                  Anadarko Basin lease operating expenses averaged $1.69 per BOE during the quarter, the lowest LOE within the Company’s operating regions.

·                  Newfield’s production in the Williston Basin increased during the third quarter, averaging nearly 22,000 BOEPD. Approximately 65% of the production was oil and the average sales price during the quarter was $45.21 per barrel.

·                  The Company today increased the mid-point of its full-year 2017 production outlook.

·                  For the fourth quarter of 2017, Newfield expects its net domestic production to average approximately 168,000 BOEPD.

·                  The mid-point for 2017 domestic guidance was raised to approximately 152,000 BOEPD (previous guidance: 149,600 BOEPD). The Company now estimates that its year-over-year domestic production growth, adjusted for prior-year asset sales, will be approximately 9 - 10%.

·                  The mid-point estimate for 2017 total company production was increased to approximately 156,700 BOEPD (previous guidance was 153,600 BOEPD).

·                  At the end of the third quarter, the Company had approximately $428 million of cash on hand.

·                  Recent Anadarko Basin operational highlights include:

·                  In STACK, Newfield has now completed the Company’s fourth operated pilot on increased density spacing. The Freeman development pad initiated production early in the third quarter from nine SXL infill wells in the Meramec. The wells were completed with Newfield’s GEN17 completion design of 2,100 pounds of proppant per foot and 2,100 gallons of liquid per foot. Although early, cumulative average production, both oil and barrels of oil equivalent, after 60 days is outperforming the Company’s 1.1 MMBOE gross type curve.

·                  After more than 120 days, production from nine Meramec infill wells (both oil and barrels of oil equivalent) on the Stark pad continues to exceed the Company’s 1.1 MMBOE gross type curve. Newfield estimates that this development is generating a before tax internal rate of return of more than 50% at a flat price of $50 per barrel (NYMEX WTI).

·                  Newfield today provided data on eight recent HBP wells in STACK, including the play’s “record setting” Hoile well, which had the play’s highest oil production per 1,000’ of lateral over a 24-hour period. The Hoile recently commenced production with a 24-hr initial production rate of 5,100 BOEPD (67% oil) from 7,140’ lateral. Thirty-day production data is not yet available.  A comprehensive list of recent STACK completions can be found in @NFX.

·                  In SCOOP, two developments were brought on-line during the third quarter. The McClelland pad was our first development with eight infill wells drilled in the Woodford. The average 30-day rate for the eight infill wells was 1,966 BOEPD (36% oil). The McClelland infill wells are performing in-line with Newfield’s recent Tina development (2Q17 completions), where production per well has averaged 1,465 BOEPD (41% oil) over the first 120 days. Complete details on both pads referenced above can be found in @NFX.

·                  The Holinsworth development pad, also located in SCOOP, commenced production late in the third quarter from seven infill wells drilled in the Woodford. Initial 24-hour production per well averaged 3,193 BOEPD (33% oil). Thirty day production data is not yet available. In addition, a non-operated SCOOP development was recently completed and is currently producing at high rates from the condensate window of the play. Newfield’s net share is more than 10,000 BOEPD, of which only 11% is black oil. The company expects that the rich gas will lead to higher natural gas volumes in the fourth quarter — see fourth quarter guidance in this news release.

Third Quarter 2017 Financial and Production Summary

For the third quarter, the Company recorded net income of $87 million, or $0.44 per diluted share (all per share amounts are on a diluted basis).

After adjusting for the effect of the tax benefit and unrealized derivative loss during the period, net income would have been $104 million, or $0.52 per share.

Explanation and Reconciliation of Non-GAAP Financial Measures

Adjusted Net Income (Earnings Stated Without the Effect of Certain Items)

Earnings stated without the effect of certain items is a non-GAAP financial measure. Earnings without the effect of these items are presented because they affect the comparability of operating results from period to period. In addition, earnings without the effect of these items are more comparable to earnings estimates provided by securities analysts. This measure should not be considered an alternative to net income (loss) as defined by generally accepted accounting principles.

A reconciliation of earnings for the third quarter of 2017 stated without the effect of certain items to net income (loss) is shown below (in millions, except per share data):

Discretionary Cash Flow from Operations

Discretionary cash flow from operations represents net cash provided by operating activities before changes in operating assets and liabilities and is presented because of its acceptance as an indicator of an oil and gas exploration and production company’s ability to internally fund exploration and development activities and to service or incur additional debt. This measure should not be considered an alternative to net cash provided by operating activities as defined by generally accepted accounting principles.
