OGIS FloridaBob Watson, President and CEO of Abraxas, will be presenting at the IPAA OGIS conference in Fort Lauderdale Florida on February 13, 2013 at 11:25AM EST. An updated presentation and webcast will be available at http://www.investorcalendar.com/CEPage.asp?ID=170412 and on Abraxas’ website, www.abraxaspetroleum.com. Bob Watson, President and CEO of Abraxas, commented, “We are quite pleased with the early performance of the Mustang 1H. This is our third well in the WyCross area, and materially outperformed our previous best well the Cobra 1H. In the Bakken, we elected to complete the Ravin 2H and 3H simultaneously in February opposed to individual completions a month apart, which should lead to reasonable cost savings. We look forward to updating the market post our upcoming Bakken and Eagle Ford completions.” Abraxas Petroleum Corporation is a San Antonio based crude oil and natural gas exploration and production company with operations across the Rocky Mountain, Mid-Continent, Permian Basin and onshore Gulf Coast regions of the United States and in the province of Alberta, Canada.
