Lonestar Announces 30-Day Rate Of 2,123 BOEPD For Brazos County Well

FORT WORTH, Texas, June 21, 2017 /PRNewswire/ -- Lonestar Resources US Inc. (NASDAQ: LONE) (together with its subsidiaries, "Lonestar") provided an update on its Wildcat B #1H well located in Brazos County, Texas.  The well was drilled and completed to a total measured depth of 19,800 feet (approximately 11,000 feet true vertical depth).  Lonestar owns a 50% working interest in the Wildcat B #1H well.  The well was fracture stimulated with a total of 16.6 million pounds of proppant over a perforated interval of 8,166 feet (2,028 pounds per foot) in 41 stages.  Previously, Lonestar announced initial test rates of 1,475 BOE per day.  The Wildcat B1H has now been on production for 40 days. 

Today, the Company announced that the Wildcat B1H well has established a 30-day production rate of 2,123 barrels of oil equivalent per day (Boe/d), consisting of 890 barrels of oil per day (42%), 764 barrels of natural gas liquids (36%) and 2,815 Mcf per day of natural gas (22%).  These rates were achieved on a 20/64-inch choke. Lonestar has leases covering 9,555 gross / 6,420 net acres in the Wildcat area, which holds 46 drilling locations, based on 800-foot spacing. At year-end 2016, Lonestar had not recorded any proved reserves to this area.

Lonestar's Chief Executive Officer, Frank D. Bracken, III, commented, "The early results of our first well in the Brazos Deep portion of the Eagle Ford Shale play are extremely encouraging.  The rates achieved thus far are considerably higher than the average for the area. I believe this a testament to the quality of our technical team.  We are currently interpreting our 3-D seismic over our leasehold.  Thereafter, we will formulate our development plan for this area, which holds significant production and reserve potential for our Company." 

Cautionary & Forward Looking Statements

Lonestar Resources US, Inc. cautions that this press release contains forward-looking statements, including, but not limited to, statements about the new chairman's expertise, ability and anticipated contributions to Lonestar; Lonestar's execution of its growth strategies; growth in Lonestar's leasehold, reserves and asset value; and Lonestar's ability to create shareholder value. These statements involve substantial known and unknown risks, uncertainties and other important factors that may cause our actual results, levels of activity, performance or achievements to be materially different from the information expressed or implied by these forward-looking statements. These risks and uncertainties include, but are not limited to, the following:  volatility of oil, natural gas and NGL prices, and potential write-down of the carrying values of crude oil and natural gas properties; inability to successfully replace proved producing reserves; substantial capital expenditures required for exploration, development and exploitation projects; potential liabilities resulting from operating hazards, natural disasters or other interruptions; risks related using the latest available horizontal drilling and completion techniques; uncertainties tied to lengthy period of development of identified drilling locations; unexpected delays and cost overrun related to the development of estimated proved undeveloped reserves; concentration risk related to properties, which are located primarily in the Eagle Ford Shale of South Texas; loss of lease on undeveloped leasehold acreage that may result from lack of development or commercialization; inaccuracies in assumptions made in estimating proved reserves; our limited control over activities in properties Lonestar does not operate; potential inconsistency between the present value of future net revenues from our proved reserves and the current market value of our estimated oil and natural gas reserves; risks related to derivative activities; losses resulting from title deficiencies; risks related to health, safety and environmental laws and regulations; additional regulation of hydraulic fracturing; reduced demand for crude oil, natural gas and NGLs resulting from conservation measures and technological advances; inability to acquire adequate supplies of water for our drilling operations or to dispose of or recycle the used water economically and in an environmentally safe manner; climate change laws and regulations restricting emissions of "greenhouse gases" that may increase operating costs and reduce demand for the crude oil and natural gas; fluctuations in the differential between benchmark prices of crude oil and natural gas and the reference or regional index price used to price actual crude oil and natural gas sales; and the other important factors discussed under the caption "Risk Factors" in our Registration Statement on Form 10, as amended and filed with the Securities and Exchange Commission, or the SEC, on June 9, 2016, our Quarterly Reports on Form 10-Q filed with the SEC, as well as other documents that we may file from time to time with the SEC. We may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements, and you should not place undue reliance on our forward-looking statements. Actual results or events could differ materially from the plans, intentions and expectations disclosed in the forward-looking statements we make. The forward-looking statements in this presentation represent our views as of the date of this presentation. We anticipate that subsequent events and developments will cause our views to change. However, while we may elect to update these forward-looking statements at some point in the future, we have no current intention of doing so except to the extent required by applicable law.

The SEC permits oil and gas companies, in their filings with the SEC, to disclose only proved, probable and possible reserves that meet the SEC's definitions for such terms. Estimates of reserves in this press release are based on economic assumptions with regard to commodity prices that differ from the prices required by the SEC (historical 12 month average) to be used in calculating reserves estimates prepared in accordance with SEC definitions and guidelines. In addition, reserve engineering is a complex and subjective process of estimating underground accumulations of oil and natural gas that cannot be measured in an exact way and the accuracy of any reserve estimate is a function of the quality of available data and of engineering and geological interpretation and judgment. The estimates of reserves in this press release were prepared by the Company's internal reserve engineers and are based on various assumptions, including assumptions related to oil and natural gas prices as discussed above, drilling and operating expenses, capital expenditures, taxes and availability of funds and are subject to confirmation and revision from the Company's independent reserve engineering firm. The Company's internal estimates of reserves may not be indicative of or may differ materially from the year-end estimates of the Company's reserves prepared by a third party as a result of the SEC pricing and other assumptions employed by an independent reserve engineering firm. Investors are urged to consider closely the disclosure in the Company's filings with the SEC, which you can obtain from the SEC's website at www.sec.gov.
