Stone Energy Corporation Announces 2017 Year-end Reserves, Production Update and 2018 Preliminary Capital Budget

LAFAYETTE, La., Jan. 30, 2018 /PRNewswire/ -- Stone Energy Corporation (NYSE: SGY) ("Stone" or the "Company") today announced its estimated proved reserves, production volumes, and liquidity for year-end December 31, 2017, its capital expenditure budget for 2018, and production guidance for the first quarter of 2018.  Some highlights include:

• Estimated proved reserves totaled approximately 32.5 million barrels of oil equivalent ("Boe") at December 31, 2017
• Production volumes averaged approximately 17.6 thousand Boe per day for the three months ended December 31, 2017
• The Board of Directors authorized a 2018 capital expenditure budget of up to $212 million
• Cash totaled approximately $282.2 million at December 31, 2017

Interim Chief Executive Officer and President James M. Trimble stated, "We exited 2017 with solid operational results and a strong financial position, and with several prospective near-term, deep water drilling opportunities.  We drilled a successful development well at Mt. Providence in December 2017 and expect it to be tied into our Pompano facility by the third quarter of 2018.  We currently expect to spud the Stone-generated Derbio exploration prospect in late-February 2018 and could have another non-operated drilling opportunity in the first half of 2018.  Our strong liquidity position provides us with financial flexibility for 2018.  In addition, we continue to advance the previously announced combination of Stone with Talos Energy LLC, which we believe will create incremental long-term value for our shareholders."

Year-End 2017 Estimated Proved Reserves

Estimated proved reserves as of December 31, 2017 totaled approximately 32.5 million barrels of oil equivalent ("MMBoe"), compared to approximately 35.4 MMBoe of estimated proved reserves for the Gulf of Mexico ("GOM") at year-end 2016, which excludes reserves from the Appalachia properties that Stone sold on February 27, 2017.  The year-end 2017 estimated proved reserves were 67% oil, 26% natural gas, and 7% natural gas liquids ("NGLs"), on an equivalent basis. The changes in GOM estimated proved reserves from year-end 2016 to year-end 2017 included production of approximately 7.0 MMBoe, net upward performance revisions of approximately 4.0 MMBoe, and pricing-related revisions of approximately 0.1 MMBoe.  In the GOM, due primarily to the upward revisions of previous estimates, Stone replaced approximately 59% of 2017 production.

The year-end 2017 estimated proved reserves included proved developed reserves of approximately 28.3 MMBoe and proved undeveloped reserves of approximately 4.2 MMBoe.  In addition to proved reserves, estimated probable reserves totaled approximately 20.8 MMBoe and estimated possible reserves totaled approximately 35.4 MMBoe at December 31, 2017.

All of Stone's year-end 2017 estimated proved, probable, and possible reserves were independently engineered by Netherland, Sewell & Associates, Inc.

2017 Production Results and First Quarter 2018 Production Guidance

Net daily production during the fourth quarter of 2017 averaged approximately 17.6 thousand barrels of oil equivalent ("MBoe") per day, compared to net daily production of approximately 19.2 MBoe per day for the quarter ended September 30, 2017.  Fourth quarter 2017 volumes included five full days of downtime from Hurricane Nate and a ten day planned shut-in of the Pompano platform in November to replace a compressor engine.  The production mix for the fourth quarter of 2017 was approximately 72% oil, 21% natural gas, and 7% NGLs.  Net daily production volumes from the GOM for full year 2017 averaged 19.2 MBoe per day, which excludes production from the Appalachia properties that Stone sold on February 27, 2017.  We expect production rates to range from 17.5 MBoe per day to 18.0 MBoe per day for the first quarter of 2018.

2018 Capital Expenditure Budget

Stone's Board of Directors has authorized a full-year 2018 capital expenditure budget of up to $212 million, which excludes acquisitions and capitalized SG&A and interest, and does not give effect to the potential Talos combination.  The budget is spread across Stone's major areas of investment with approximately 36% allocated to exploration, 27% to development, and 37% to P&A expenditures. The allocation of capital across the various areas is subject to change based on several factors, including permitting times, rig availability, non-operator decisions, farm-in opportunities, and commodity pricing.

Liquidity Update

As of December 31, 2017, Stone's liquidity approximated $369.6 million, which included approximately $87.4 million of undrawn capacity under the Company's revolving credit facility plus approximately $263.5 million in cash on hand and approximately $18.7 million in cash being held in a restricted account to satisfy near-term plugging and abandonment activities.

As of December 31, 2017, Stone's outstanding debt totaled approximately $235.5 million, consisting of $225.0 million of 7.50% Senior Second Lien Notes due 2022 and approximately $10.5 million outstanding under a building loan.  Further, the Company had no outstanding borrowings and outstanding letters of credit of approximately $12.6 million under its $100 million borrowing base. 

We expect that cash flows from operating activities, cash on hand, and availability under our revolving credit facility will be adequate to meet the current 2018 operating and capital expenditure needs of the Company.
