Apache Announces First Canning Basin Oil Discovery Offshore Western Australia

HOUSTON, Aug. 18, 2014 /PRNewswire/ -- Apache Corporation (NYSE, Nasdaq: APA) today announced an oil discovery at the Phoenix South-1 well – the company's first discovery in Australia's offshore Canning Basin.

Wireline and formation pressure tools have confirmed at least four discrete oil columns ranging in thickness between 85 and 151 feet (26 to 46 meters) in the Triassic Lower Keraudren formation, within an overall, sand-rich section between 13,648 and 14,763 feet below sea level (4,160 to 4,500 meters).

Six light oil samples have been recovered from three intervals to date; permeability measurements from the sampled zones indicate a productive oil reservoir with preliminary estimates that there might be as much as 300 million barrels of oil in place.* Evaluation of the formation penetrated in the Phoenix South-1 is under way, and final calculation of hydrocarbon pay will depend on additional analysis.

The Phoenix South-1 well is located in permit WA-435-P,  offshore western Australia, 110 miles (180 km) north of Port Hedland in 435 feet (133 meters) of water. Apache has a 40-percent interest and operatorship of WA-435-P and the adjacent permit WA-437-P; co-venturers are Carnarvon Petroleum (20 percent), Finder Exploration (20 percent) and JX Nippon (20 percent).  Apache also has exercised its option to acquire 40-percent interest and operatorship of two additional adjacent permits (WA-436-P and WA-438-P) for a total position of more than 5 million acres (20,000 square kilometers).

The area includes a number of large, undrilled structures, including the Roc prospect on WA-437-P, with potential to be significant additional oil accumulations.  Further drilling and evaluation is planned for 2015.

"Although evaluation is at an early stage, Phoenix South-1 is an exciting result," said Thomas E. Voytovich, Apache's executive vice president and chief operating officer – International. "The oil and reservoir quality we have seen point to a commercial discovery.  If these results are borne out by further appraisal drilling, Phoenix South may represent a new oil province for Australia. We look forward to working with our partners to continue evaluation of the area."

While forward-looking statements are based on assumptions and analyses made by us that we believe to be reasonable under the circumstances, whether actual results and developments will meet our expectations and predictions depend on a number of risks and uncertainties which could cause our actual results, performance, and financial condition to differ materially from our expectations.

Cautionary Note to Investors
The United States Securities and Exchange Commission ("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. Apache may use certain terms in this press release, such as "preliminary estimate of oil in place," and other similar terms that the SEC guidelines strictly prohibit Apache from including in filings with the SEC. Such terms do not take into account the certainty of resource recovery, which is contingent on exploration success, technical improvements in drilling access, commerciality and other factors, and are therefore not indicative of expected future resource recovery and should not be relied upon. Investors are urged to consider carefully the disclosure in Apache's Annual Report on Form 10-K for the fiscal year ended December 31, 2013, available from Apache at www.apachecorp.com or by writing Apache at: 2000 Post Oak Blvd., Suite 100, Houston, Texas 77056 (Attn: Corporate Secretary).
