FORT WORTH, Texas, Feb. 6, 2019 /PRNewswire/ -- Lonestar Resources US Inc. (NASDAQ: LONE) announced that its proved reserves at December 31, 2018 increased 27% to 93.3 million barrels of oil equivalent ("MMBOE") calculated using SEC guidelines.  All of the Company's proved reserves are located in the Eagle Ford Shale.

Lonestar's proved reserves at December 31, 2018 are comprised of 53.4 million barrels of crude oil and condensate, 19.9 million barrels of natural gas liquids ("NGL's"), and 120.2 billion cubic feet of natural gas.  By energy content, Lonestar's proved reserves are weighted 79% to crude oil, condensate and NGL's.  See Table 1 for details. 

• In 2018, Lonestar added a total of 23.8 MMBOE, which consisted of 11.3 MMBOE through acquisitions, 8.3 MMBOE through extensions and discoveries, and 4.3 MMBOE through positive reserve revisions. These reserve additions were equivalent to 586% of Lonestar's 2018 production.
• Lonestar's Proved Developed reserves increased 47% to 26.8 MMBOE and the PV-10 associated with its Proved Developed reserves increased 81% to $464.9 million using SEC guidelines.
• Lonestar's capital expenditures totaled $209.9 million for the year ended December 31, 2018. Lonestar's all-sources finding and development costs were $8.80 per BOE. Drillbit-only finding and developing costs averaged $12.58 per BOE.
• Including 2018 results, Lonestar's five-year reserves replacement ratio has been 716% and the five-year all-sources F&D cost averages $8.94 per BOE.
• In 2018, Lonestar's Proved & Probable reserves increased 31% to 121.5 MMBOE, which is comprised of 67.4 million barrels of crude oil and condensate, 27.0 million barrels of natural gas liquids, and 162.7 billion cubic feet of natural gas. Using SEC guidelines, PV-10 for Proved & Probable reserves exceeds $1.3 billion.
• Lonestar's Proved & Probable reserves included 261 drilling locations which were assigned reserves by the Company's independent petroleum engineers, equating to approximately 15 years of drilling activity at Lonestar's current rate of drilling.

Lonestar has also calculated reserves information at an alternate price deck of $55.00/bbl for West Texas Intermediate crude oil and $2.75/MMBTU for Henry Hub natural gas ("$55 Flat Price Deck"), which closely mirrors current forward benchmark prices.  On this basis, the PV-10 associated with Lonestar's Proved reserves was $782.5 million and the PV-10 associated with the Company's Proved & Probable reserves was $919.9 million.

Lonestar's Chief Executive Officer, Frank D. Bracken, III commented, "2018 was another year of tremendous growth for Lonestar, coming from a balanced program of drilling and acquisitions.  We extended our track-record of low-cost reserve growth, registering exceptional all-sources finding and development costs of $8.80 per BOE while increasing our Proved reserves by 27%.  This reserve growth, which was prudently financed, positions Lonestar to significantly increase shareholder value in 2019 and beyond." 

Bracken added, "At Lonestar, our objective is to deliver demonstrable growth in the value of our reserves on a per-share basis, while continually improving our balance sheet and financial flexibility.  In 2018, we have delivered on that objective again.  Our internal value benchmark, which is $55 Flat Price Deck PV-10, net of debt, increased 20% to $8.89 per fully diluted share based on Proved reserves and increased 22% to $12.33 per fully diluted share based on Proved & Probable reserves.  I believe our growth in per-share value is even more impactful when we consider the fact that in the same time period, Lonestar reduced its Debt/EBITDAX ratio from 3.6x to 2.6x at year-end 2018."

The table below summarizes Lonestar's year-end proved reserves and PV-10 by region as determined by the Company's independent petroleum engineers, W.D. Von Gonten & Co. Petroleum Engineers. Based on rules of the U.S. Securities and Exchange Commission, for the year ended December 31, 2018, Lonestar's proved reserves were estimated using the 12-month average price calculated as the unweighted arithmetic average of the spot price on the first day of each month preceding the 12 months prior to the end of the reporting period. This methodology resulted in an average oil price of $65.56 per barrel and an average natural gas price of $3.10 per million British Thermal Units ("MMBTU"), an increase of 28% for crude oil and  an increase of 5% for natural gas, as compared to an average of oil price of $51.34 per barrel and an average natural gas price of $2.96 per MMBTU used to estimate Lonestar's proved reserves for the year ended December 31, 2017.

Table 4: Proved & Probable Reserves and PV-10 at SEC Pricing
(As of December 31, 2018)

Because the pricing utilized in the SEC methodology is higher than current benchmark market prices for crude oil, NGL's and natural gas, Lonestar has also calculated the PV-10 of its Proved reserves at a flat pricing deck of $55.00 for crude oil and $2.75 for natural gas (as described below, "$55 flat deck pricing").  On this basis, the Company's proved reserves were 92.0 MMBOE and PV-10 was $782.5 million. See Table 5 for details.
