MIDLAND, Texas, Feb. 14, 2017 (GLOBE NEWSWIRE) -- Diamondback Energy, Inc. (NASDAQ:FANG) ("Diamondback" or the "Company") today announced financial and operating results for the fourth quarter ended December 31, 2016.

HIGHLIGHTS

• Q4 2016 production of 51.9 Mboe/d (73% oil), up 16% over Q3 2016 and 38% year over year
• Full year 2016 production of 43.0 Mboe/d (73% oil), up 30% year over year
• Q4 2016 average realized prices were $46.72 per barrel of oil, $2.53 per Mcf of natural gas and $17.70 per barrel of natural gas liquids, resulting in a total equivalent price of $38.72/boe, up 13% from the Q3 2016 total equivalent price of $34.39/boe
• Q4 2016 cash operating costs of $8.48/boe, including LOE of $4.89/boe and cash G&A of $0.92/boe
• Proved reserves as of December 31, 2016 of 205.5 MMboe (68% oil), up 31% year over year; proved developed finding and development ("PD F&D") costs of $7.26/boe
• Previously announced pending acquisition of Brigham Resources expected to close at the end of February 2017
• Increasing pro forma full year 2017 production guidance to 69.0 to 76.0 Mboe/d, up from 64.0 to 73.0 Mboe/d
• Operating six horizontal rigs, including first operated rig in the Southern Delaware Basin, with plans to add two additional rigs after the closing of the pending Brigham Resources acquisition

"Diamondback achieved over 40% production growth in the second half of 2016 by showcasing our ability to respond quickly to a rising commodity price environment. We ended the year operating five rigs, and as I said in November, we are just beginning to bear the fruit of our activity ramp. We recently added a sixth operated rig, our first in the Southern Delaware Basin, and plan to add two more rigs to the Delaware Basin following the closing of the pending Brigham transaction at the end of February," stated Travis Stice, Chief Executive Officer of Diamondback.

Mr. Stice continued, "After doubling our Tier 1 acreage in the second half of 2016, our focus now shifts to execution. Diamondback's success has and continues to be driven by our ability to identify accretive opportunities, integrate these efficiently into operations and convert resource into cash flow. Our resource expansion into the Southern Delaware Basin marks another opportunity to expand our operational leadership in regards to low cost operations, best in class well productivity and, above all, creating shareholder value. Our updated 2017 guidance implies over 65% production growth at the midpoint, while conservatively preparing for potential service cost inflation with respect to capital guidance. Our pro forma balanced footprint secures Diamondback's ability to generate leading growth rates within cash flow for years to come."

OPERATIONAL HIGHLIGHTS

Diamondback's Q4 2016 production was 51.9 Mboe/d (73% oil), up 38% year over year from 37.6 Mboe/d in Q4 2015, and up 16% quarter over quarter from 44.9 Mboe/d in Q3 2016. Average daily production for the full year 2016 was 43.0 Mboe/d (73% oil), exceeding the high end of its guidance range of 41.0 to 42.0 Mboe/d and up 30% year over year from 33.1 Mboe/d in 2015.

During the fourth quarter of 2016, Diamondback averaged five operated rigs, drilled 25 gross horizontal wells and completed 23 operated horizontal wells with an average of two completion crews. Operated completions consisted of 14 Lower Spraberry wells, six Wolfcamp A wells, two Middle Spraberry wells and one Wolfcamp B well. In January 2017, Diamondback added a sixth operated horizontal rig to begin development on the Company's previously acquired Southern Delaware Basin acreage. The Company anticipates closing its previously announced acquisition of leasehold interests and related assets from Brigham Resources at the end of February. Subsequent to the transaction close, Diamondback plans to operate two additional rigs in the Southern Delaware Basin.

Diamondback continues to decrease drilling times, lower costs and achieve new Company records. During the fourth quarter of 2016, Diamondback drilled an 8,200 foot lateral well in Glasscock County in less than nine days from spud to total depth, a new record for the Company. Diamondback also drilled a 13,500 foot lateral in Midland County in 20.3 days, a new record for the Company.

Diamondback is increasing its pro forma full year 2017 production guidance to 69.0 to 76.0 Mboe/d, the midpoint of which is up over 65% from 2016 average daily production. The Company expects to complete 130 to 165 gross wells with an average lateral length of approximately 8,500 feet.

MIDLAND BASIN WELL RESULTS

In Howard County, Diamondback continues to see strong extended performance from its latest pad using a high-density near-wellbore completion design. These wells targeted the Lower Spraberry, Wolfcamp A and Wolfcamp B with an average completed lateral length of 9,725 feet. The Reed 1A 1WA and the Reed 1A 1WB achieved respective peak 30-day 2-stream initial production ("IP") rates of 1,978 boe/d (89% oil) and 1,605 boe/d (90% oil). After producing over 100,000 boe in 125 days, the Reed 1A 1LS well continues to produce over 1,100 boe/d (89% oil).

In Glasscock County, Diamondback recently completed a two-well Wolfcamp A pad with an average lateral of 10,660 feet. The Ray 3427 A 4WA and Ray 3427 B 5WA achieved an average 30-day IP rate of 1,378 boe/d (85% oil) per well. After producing an average of 85 Mboe in 80 days, both wells are now producing over 1,400 boe/d (83% oil) on pump. Additionally, the Company recently completed its second and third Lower Spraberry wells in Glasscock County. These wells were completed with an average lateral of 10,423 feet and are currently in the early stages of flowback.

In Andrews County, Diamondback recently completed two Lower Spraberry wells with an average lateral of 10,000 feet and a high-density near-wellbore design. These wells have achieved an average peak 15-day IP rate of 1,564 boe/d (89% oil) per well.

RESERVES

Ryder Scott Company, L.P. prepared estimates of Diamondback's proved reserves as of December 31, 2016. Reference prices of $42.75 per barrel of oil, $2.49 per MMbtu of natural gas and $19.97 per barrel of natural gas liquids were used in accordance with applicable rules of the Securities and Exchange Commission. Realized prices with applicable differentials were $39.94 per barrel of oil, $1.36 per Mcf of natural gas and $12.91 per barrel of natural gas liquids.

Proved reserves at year-end 2016 of 205.5 MMboe represent a 31% increase over year-end 2015 reserves.  Proved developed reserves increased by 29% to 119.1 MMboe (58% of total proved reserves) as of  December 31, 2016, reflecting the continued development of the Company's horizontal well inventory. Crude oil represents 68% of Diamondback's total proved reserves.

Net proved reserve additions of 64.3 MMboe resulted in a reserve replacement ratio of 409% (defined as the sum of extensions, discoveries, revisions and purchases, divided by annual production). The organic reserve replacement ratio was 380% (defined as the sum of extensions, discoveries and revisions, divided by annual production).

Purchases of reserves came primarily from the acquisition of working interest acreage in Reeves and Ward counties, which contributed 56% of the total purchased reserves. Mineral interest purchases by Viper contributed 37% of the total and the remaining purchases were bolt on acquisitions of working interest acreage. Extensions totaling 79.8 MMboe of reserves occurred from continued development of the Company's properties in the northwest Midland Basin and the initial development of Diamondback's properties in Howard and Glasscock counties. Development occurred in the Middle Spraberry, Lower Spraberry, Wolfcamp A and Wolfcamp B horizons. Proved developed producing extensions accounted for approximately 50% of the extension reserves and were the result of 59 wells in which the Company also owns a working interest. It also includes Diamondback's mineral interests in 33 wells, 30 of which Diamondback has a working interest. Approximately 50% of the extension reserves are from 51 proved undeveloped locations in which the Company has a working interest. Reserves also include Diamondback's mineral interests in 32 locations, 30 of which the Company also owns a working interest. Total downward revisions of 20.1 MMboe include 11.2 MMboe of pricing related revisions.

NON-GAAP FINANCIAL MEASURES

Adjusted EBITDA is a supplemental non-GAAP financial measure that is used by management and external users of our financial statements, such as industry analysts, investors, lenders and rating agencies. The Company defines Adjusted EBITDA as net income (loss) plus non-cash loss on derivative instruments, interest expense, depreciation, depletion and amortization, impairment of oil and gas properties, non-cash equity-based compensation expense, capitalized equity-based compensation expense, asset retirement obligation accretion expense, loss on extinguishment of debt and income tax (benefit) provision. Adjusted EBITDA is not a measure of net income (loss) as determined by United States' generally accepted accounting principles ("GAAP"). Management believes Adjusted EBITDA is useful because it allows it to more effectively evaluate the Company's operating performance and compare the results of its operations from period to period without regard to its financing methods or capital structure. The Company adds the items listed above to net income (loss) in arriving at Adjusted EBITDA because these amounts can vary substantially from company to company within its industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. Adjusted EBITDA should not be considered as an alternative to, or more meaningful than, net income (loss) as determined in accordance with GAAP or as an indicator of the Company's operating performance or liquidity. Certain items excluded from Adjusted EBITDA are significant components in understanding and assessing a company's financial performance, such as a company's cost of capital and tax structure, as well as the historic costs of depreciable assets, none of which are components of Adjusted EBITDA. Adjusted net income is a non-GAAP financial measure equal to net income (loss) attributable to Diamondback Energy, Inc. plus non-cash (gain) loss on derivative instruments, net, (gain) loss on the sale of assets, net, impairment of oil and gas properties, loss on extinguishment of debt and related income tax adjustments. The Company's computations of Adjusted EBITDA and adjusted net income may not be comparable to other similarly titled measures of other companies or to such measure in our credit facility or any of our other contracts.

The following tables present a reconciliation of the non-GAAP financial measure of Adjusted EBITDA to the GAAP financial measure of net income.

PV-10

PV-10 is the Company's estimate of the present value of the future net revenues from proved oil and gas reserves after deducting estimated production and ad valorem taxes, future capital costs and operating expenses, but before deducting any estimates of future income taxes.  The estimated future net revenues are discounted at an annual rate of 10% to determine their "present value."  The Company believes PV-10 to be an important measure for evaluating the relative significance of its oil and gas properties and that the presentation of the non-GAAP financial measure of PV-10 provides useful information to investors because it is widely used by professional analysts and investors in evaluating oil and gas companies.  Because there are many unique factors that can impact an individual company when estimating the amount of future income taxes to be paid, the Company believes the use of a pre-tax measure is valuable for evaluating the Company.  The Company believes that PV-10 is a financial measure routinely used and calculated similarly by other companies in the oil and gas industry.

The following table reconciles PV-10 to the Company's standardized measure of discounted future net cash flows, the most directly comparable measure calculated and presented in accordance with GAAP.  PV-10 should not be considered as an alternative to the standardized measure as computed under GAAP.
