Shale Exploration by Chevron
Chevron won approval to drill exploration wells for shale gas in three areas in eastern Romania, local news agency Mediafax reported recently. Chevron holds more than 2 million acres in Romania, including a 1.6-million-acre concession in the Barlad Shale. We plan to drill an exploration well in 2013. We hold three additional concession agreements covering 670,000 acres in southeast Romania. Acquisition of 2-D seismic data across these concessions is expected to begin in 2013.

Chevron holds about 250,000 net acres in western Alberta’s Duvernay Shale formation and approximately 200,000 overlying acres in the Montney tight rock formation. In 2012, we conducted a multiwell drilling program. Initial production to permanent facilities was achieved in late 2012. Chevron also has a 50 percent nonoperated working interest in 644,000 acres in the Horn River and Liard shale gas basins in British Columbia.

Chevron holds four shale concessions in Poland—Frampol, Grabowiec, Krasnik and Zwierzyniec—which total approximately one million acres. In the Grabowiec concession, drilling of the first well was completed in March 2012, followed by a diagnostic fracture integrity test in December 2012. A first well also was drilled in the Frampol concession in 2012. In the Zwierzyniec concession, drilling began in December 2012. Continued exploration drilling is planned for 2013.
Chevron successfully bid for the right to exclusively negotiate with the government of Ukraine for the Oleska Block. The company is expected to operate and hold a 50 percent interest in the 1.6 million-acre concession.
During 2012, Chevron drilled an initial exploratory well for shale gas in China’s Qiannan Basin, in the southwestern province of Guizhou. In 2013, we continue to evaluate the well and plan additional drilling.
In 2012, Chevron drilled two exploratory wells in the Vaca Muerta formation in Argentina’s El Trapial crude oil field. We are evaluating the results. We began drilling a third exploratory well in 2013 and are planning three additional appraisal wells. We have been producing oil at El Trapial for many years, but the concession now also has potential for shale gas production.
