Oasis Petroleum Inc. Announces Quarter and Year Ending December 31, 2017 Earnings and Provides an Operational Update and 2018 Outlook

HOUSTON, Feb. 27, 2018 /PRNewswire/ -- Oasis Petroleum Inc. (NYSE: OAS) ("Oasis" or the "Company") today announced financial and operational results for the quarter and year ended December 31, 2017 and provided its 2018 outlook.

Highlights

    --  Exceeded average daily production exit target for 2017 with 73,207
        barrels of oil equivalent per day ("Boepd") in the fourth quarter of
        2017 and produced 66,144 Boepd for the year ended December 31, 2017.
    --  Decreased lease operating expenses per Boe to $6.42 per Boe for the
        quarter ended December 31, 2017.
    --  Completed and placed on production 88 gross (58.3 net) operated wells
        while investing $517.3 million of E&P capital expenditures ("E&P
        CapEx"), which excludes acquisitions, other capital and midstream
        capital, during 2017.
    --  Acquired approximately 22,000 net acres in the over-pressured oil window
        of the Delaware Basin. The acquisition was announced in late 2017 and
        subsequently closed on February 14, 2018.
    --  More than doubled core net inventory from 483 net undeveloped locations
        at December 31, 2016 to 1,092 net undeveloped locations at December 31,
        2017, due to the expansion of the Company's core footprint in the
        Williston Basin into much of Painted Woods and its entry in the Delaware
        Basin.
    --  Oasis Midstream Partners LP ("OMP") completed its initial public
        offering resulting in net proceeds distributed to Oasis of $132.1
        million.
    --  Commenced investment in second Wild Basin gas plant with a total
        capacity of 200 million standard cubic feet per day to service gas
        production from its highly economic inventory. OMP invested $94.7
        million of capital in the second gas plant and $105.6 million of total
        capital expenditures in 2017. The Company invested $235.1 million in
        capital expenditures in midstream assets ("Midstream CapEx") in 2017,
        including the $105.6 million attributable to OMP.
    --  Successfully launched operations with second Oasis Well Services
        fracturing crew.
    --  Net cash provided by operating activities was $507.9 million for the
        year ended December 31, 2017 and $209.1 million for the fourth quarter
        of 2017. Adjusted EBITDA, a non-GAAP financial measure, was $707.7
        million for the year ended December 31, 2017 and $236.2 million for the
        fourth quarter of 2017. For a definition of Adjusted EBITDA and a
        reconciliation of Adjusted EBITDA to net income (loss) including
        non-controlling interests and net cash provided by operating activities,
        see "Non-GAAP Financial Measures" below.

"2017 was a tremendous year for Oasis. We successfully grew production 31% while spending within cash flow on the E&P side of the business," said Thomas B. Nusz, Oasis' Chairman and Chief Executive Officer. "Our Williston Basin position continues to generate top-in-class cash margins, which drives strong corporate level returns. We have supplemented our highly economic Williston Basin asset with the Forge acquisition located in the best part of the Delaware Basin. The depth of our core inventory increased organically in the Bakken and through our accretive Permian acquisition. We now have approximately 18 years of core and extended core inventory at our 2018 completion pace, which is economic at or below a $45 WTI oil price. In 2018 and 2019, we expect this capital efficient inventory to drive 15-20% production growth within cash flow on the E&P business."

"Our well services and midstream businesses continue to be critical complements of our E&P operations. We introduced a second fracturing crew midyear 2017 and successfully completed the IPO of OMP in September," added Nusz. "Oasis funded its Midstream CapEx in 2017 through OMP IPO proceeds of $132.1 million distributed to Oasis and capital spent at OMP of $105.6 million. Our midstream business has numerous highly attractive midstream investment opportunities in 2018, both in the Williston and potentially in the Delaware, all of which we expect will generate strong returns and will be built within 4-5x EBITDA multiples. Oasis plans to invest $235 million to $275 million in Midstream CapEx in 2018, of which $72 million to $90 million will be funded by OMP in 2018, and the balance is expected to be funded over time through OMP via drops."

Inventory and Leasehold Update

Oasis' total inventory increased to 2,578 net locations, of which 1,092 net locations are considered core. Core net undeveloped locations increased by 126%, from 483 net undeveloped locations at December 31, 2016 to 1,092 net undeveloped locations currently. Of the Company's 1,092 core net locations, 585 are in the Williston Basin and 507 are in the Delaware Basin.

Oasis ended the year with a leasehold position of approximately 503,000 net acres in the Williston Basin, and, as of February 14, 2018, with a leasehold position in the Delaware Basin of approximately 22,000 net acres.

2018 Plan

Highlights for 2018 include:

    --  Total E&P CapEx plan of approximately $815 million to $855 million,
        excluding acquisitions.
        --  Williston Basin - $700 million to $730 million
        --  Delaware Basin - $115 million to $125 million
    --  Completing approximately 100 to 110 gross operated wells with a working
        interest of approximately 73% in the Williston Basin and approximately
        six to eight gross operated wells with high working interest in the
        Delaware Basin in 2018.

Estimated Net Proved Reserves

The Company's estimated net proved reserves and related PV-10 are based on reports prepared by DeGolyer and MacNaughton, independent reserve engineers. The table below summarizes the Company's estimated net proved reserves and related PV-10 at December 31, 2017:

             (1)    PV-10 is a non-GAAP financial
                     measure and generally differs
                     from Standardized Measure, the
                     most directly comparable GAAP
                     financial measure, because it
                     does not include the effect of
                     income taxes on discounted
                     future net cash flows.

Liquidity and Balance Sheet

Non-GAAP Financial Measures

Cash Interest Reconciliation

Cash Interest is a supplemental non-GAAP financial measure that is used by management and external users of the Company's financial statements, such as industry analysts, investors, lenders and rating agencies. The Company defines Cash Interest as interest expense plus capitalized interest less amortization and write-offs of deferred financing costs and debt discounts included in interest expense. Cash Interest is not a measure of interest expense as determined by United States generally accepted accounting principles, or GAAP.

The following table presents a reconciliation of the GAAP financial measure of interest expense to the non-GAAP financial measure of Cash Interest for the periods presented:

Adjusted EBITDA and Free Cash Flow Reconciliations

Adjusted EBITDA and Free Cash Flow are supplemental non-GAAP financial measures that are used by management and external users of the Company's financial statements, such as industry analysts, investors, lenders and rating agencies. The Company defines Adjusted EBITDA as earnings before interest expense, income taxes, depreciation, depletion, amortization, exploration expenses and other similar non-cash or non-recurring charges. The Company defines Free Cash Flow as Adjusted EBITDA less Cash Interest and CapEx, excluding capitalized interest. Adjusted EBITDA and Free Cash Flow are not measures of net income (loss) or cash flows as determined by GAAP.

The following table presents reconciliations of the GAAP financial measures of net income (loss) including non-controlling interests and net cash provided by (used in) operating activities to the non-GAAP financial measures of Adjusted EBITDA and Free Cash Flow for the periods presented:

Adjusted Net Income (Loss) Attributable to Oasis and Adjusted Diluted Earnings (Loss) Attributable to Oasis Per Share

Adjusted Net Income (Loss) Attributable to Oasis and Adjusted Diluted Earnings (Loss) Attributable to Oasis Per Share are supplemental non-GAAP financial measures that are used by management and external users of the Company's financial statements, such as industry analysts, investors, lenders and rating agencies. The Company defines Adjusted Net Income (Loss) Attributable to Oasis as net income (loss) after adjusting for (1) the impact of certain non-cash and non-recurring items, including non-cash changes in the fair value of derivative instruments, impairment, and other similar non-cash and non-recurring charges, (2) the impact of net income attributable to non-controlling interests and (3) the non-cash and non-recurring items' impact on taxes based on the Company's effective tax rate applicable to those adjusting items, excluding net income attributable to non-controlling interests, in the same period. Adjusted Net Income (Loss) Attributable to Oasis is not a measure of net income (loss) as determined by GAAP. The Company defines Adjusted Diluted Earnings (Loss) Attributable to Oasis Per Share as Adjusted Net Income (Loss) Attributable to Oasis divided by diluted weighted average shares outstanding.

The following table presents reconciliations of the GAAP financial measure of net income (loss) attributable to Oasis to the non-GAAP financial measure of Adjusted Net Income (Loss) Attributable to Oasis and the GAAP financial measure of diluted earnings (loss) attributable to Oasis per share to the non-GAAP financial measure of Adjusted Diluted Earnings (Loss) Attributable to Oasis Per Share for the periods presented:

             (3)    The tax impact is computed
                     utilizing the Company's

                     non-cash and non-recurring
                     items. The tax impact was not
                     computed for the tax reform
                     rate change adjustments.
