FORT WORTH, Texas, Oct 18, 2010 (BUSINESS WIRE) --

Approach Resources Inc. (NASDAQ: AREX) today announced highlights from its investor and analyst meeting held on October 18, 2010, in New York City. Key highlights from the meeting include:

• A detailed, technical discussion of the Wolfcamp Shale, Dean and Clearfork (the "Wolffork") resource play in the Permian Basin
• An estimated 119 to 182 MMBoe of oil and gas in place per 640 acres based on whole core and petrophysical analyses
• Increased Permian Basin acreage position to over 93,000 net acres
• Plans to drill and recomplete additional Wolffork pilot wells during the fourth quarter of 2010, including a horizontal well targeting the Wolfcamp Shale
• Borrowing base increase to $150 million, providing $99 million in liquidity at September 30, 2010

J. Ross Craft, Approach's President and Chief Executive Officer said, "During the investor and analyst meeting today, we provided a summary of our detailed geological and petrophysical study of the Wolfcamp and Clearfork formations across our West Texas acreage position. We expect that the Wolffork play will significantly enhance our opportunities in Permian. We believe we are uniquely positioned with a large, primarily contiguous block of acreage, extensive data, excellent team of geoscientists and engineers and strong financial position to capitalize on these opportunities. As with any new shale play, there is room for improvement in cost and completion technique. We have drilled over 400 wellbores with the Wolffork behind pipe and have an extensive inventory of multiple-pay locations across our 93,000 net acres. Given these opportunities, I believe we have exceptional resource potential that highlights our commitment to delivering long-term stockholder value."

Wolffork Shale Oil Resource Play

Approach identified the Wolffork through extensive regional mapping, using 3-D seismic data from over 135,000 acres and well data from over 400 wellbores that we have drilled and completed while targeting the deeper Canyon, Strawn and Ellenburger zones. The Wolffork is comprised of three stacked pay zones, the Clearfork, Dean and Wolfcamp Shale formations. Petrophysical analyses indicate more than 2,500 feet of gross pay from the Wolffork.

Based on log data and whole-core analyses, we believe that the Wolfcamp Shale has total organic carbon content ranging from 2.2% to 7.2%, porosity ranging from 4% to 11% (density porosity ranges from 8% to 15%) and high concentration of natural fractures.

Wolffork Reserve Potential

Approach estimates that, based on whole-core and detailed petrophysical analyses, there is significant potential oil and gas in place attributable to the Wolffork.

Formation				Estimated Oil and Gas In Place / 640 Acres (MMBoe)
Wolfcamp				118.9
Wolfcamp, Dean				125.6
Wolfcamp, Dean, Clearfork				181.7

The Wolfcamp Shale is over 1,000 feet thick and heavily fractured, ideal for horizontal drilling. We estimate 343 MBoe of potential recoverable reserves for a horizontal well targeting the Wolfcamp.

Results from Wolfcamp Shale Pilot Program and Estimated Ultimate Recovery ("EUR")

To date, we have recompleted four wells in the Wolfcamp Shale. All four pilot wells became producers. Based on our regional study, production data from our pilot wells and from adjacent operators, we estimate EURs ranging from 55 MBoe to 83 MBoe for a Wolfcamp recompletion, 90 MBoe to 135 MBoe for a Wolffork recompletion, 204 MBoe to 306 MBoe for a Canyon Wolffork new drill and 354 MBoe to 530 MBoe for a Wolfcamp horizontal well.

Fourth Quarter 2010 Plans

During the fourth quarter of 2010, we plan to further delineate the Wolffork trend across our acreage position. Our Wolffork pilot program for the fourth quarter of 2010 is outlined below.

• Drill one horizontal well, the Cinco Terry "M" 901-H, targeting the Wolfcamp Shale at the end of October 2010. Approach expects to complete the horizontal well during the first quarter of 2011.
• Recomplete the Cinco Terry 1601, targeting the Wolfcamp Shale zone.
• Recomplete two wells in Ozona Northeast, targeting the Wolffork.
• Complete the Baker "C" 1201, targeting the Wolffork and Canyon Sands zones.

Liquidity Update

We have a $200 million revolving credit agreement with a $115 million borrowing base, of which $51.1 million was drawn at September 30, 2010. At September 30, 2010, our liquidity was $64 million. We expect our borrowing base will increase by $35 million to $150 million by November 2010. Including the borrowing base increase, our liquidity was $99 million at September 30, 2010. See "Supplemental Financial Measure - Liquidity" below for our definition of "liquidity."

Supplemental Financial Measure - Liquidity

Liquidity is calculated by adding the net funds available under our revolving credit facility and cash and cash equivalents. We use liquidity as an indicator of the Company's ability to fund development and exploration activities. However, this measurement has limitations. This measurement can vary from year to year for the Company and can vary among companies based on what is or is not included in the measurement on a company's financial statements. This measurement is provided in addition to, and not as an alternative for, and should be read in conjunction with, the information contained in our financial statements prepared in accordance with GAAP (including the notes), included in our Securities and Exchange Commission ("SEC") filings and posted on our website at www.approachresources.com.

Without limiting the generality of the foregoing, forward-looking statements contained in this press release specifically include the expectations of management regarding plans, strategies, objectives, anticipated financial and operating results of the Company, including as to the Company's Wolffork shale resource play, estimated oil and gas in place and recoverability of the oil and gas, estimated reserves and drilling locations, capital expenditures, typical well results and well profiles, internal rates of return and future production included in the press release. These statements are based on certain assumptions made by the Company based on management's experience and technical analyses, current conditions, anticipated future developments and other factors believed to be appropriate and believed to be reasonable by management. When used in this press release, the words "will," "potential," "believe," "intend," "expect," "may," "should," "anticipate," "could," "estimate," "plan," "predict," "project," "profile," "model," or their negatives, other similar expressions or the statements that include those words, are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. Such statements are subject to a number of assumptions, risks and uncertainties, many of which are beyond the control of the Company, which may cause actual results to differ materially from those implied or expressed by the forward-looking statements.

Cautionary Statements Regarding Oil and Gas Quantities

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, and price and cost sensitivities for such reserves, and prohibits disclosure of resources that do not constitute such reserves. The Company uses the terms "estimated ultimate recovery" or "EUR," reserve "potential," "upside," "oil and gas in place" or "OGIP," "OIP," "OOIP" or "GIP," and other descriptions of volumes of reserves potentially recoverable through additional drilling or recovery techniques that the SEC's rules may prohibit the Company from including in filings with the SEC. These estimates are by their nature more speculative than estimates of proved, probable and possible reserves and accordingly are subject to substantially greater risk of being actually realized by the Company.

EUR estimates, drilling locations and OGIP estimates have not been risked by the Company. Actual locations drilled and quantities that may be ultimately recovered from the Company's interest will differ substantially. There is no commitment by the Company to drill all of the drilling locations that have been attributed these quantities. Factors affecting ultimate recovery include the scope of the Company's ongoing drilling program, which will be directly affected by the availability of capital, drilling and production costs, availability of drilling and completion services and equipment, drilling results, leases expirations, regulatory approval and actual drilling results, including geological and mechanical factors affecting recovery rates. Estimates of unproved reserves, per well EUR, OGIP and upside potential may change significantly as development of the Company's oil and gas assets provides additional data.
