SAN DIEGO, CA - June 20, 2011 (Investorideas.com energy stocks newswire) - Osage Exploration and Development, Inc. (OTCBB: OEDV), an independent exploration and production company, reports it continues to expand the Nemaha Ridge Mississippian prospect and has reached 11,000 net mineral acres across 40 sections in Logan County, Oklahoma. Partners in the project include Slawson Exploration Company as the Operator of the project, owning 45%, US Energy Development Corporation with 30%, and Osage Exploration has 25%.

"As we move forward in developing this project, we remain committed to expanding our footprint. While our Colombian assets continue to perform well, it is fair to say that we are very focused on building our Oklahoma exposure for the immediate future.

"It is a rare opportunity that we have with this Mississippian project. It is a tremendously economic target in its own right, and additionally this area has multiple formations that have historically produced oil and gas such as the Cherokee sands, Layton, Cleveland, Hunton Lime, Viola, Woodford Shale, and Oswego. It is anticipated that many of these formations may be found productive over the prospect acreage as development and analysis progresses," stated Kim Bradford, Chairman and CEO.

"We absolutely believe that we have years of drilling ahead of us because of the stacked-payzones, and our continually expanding acreage. We have acquired excellent leasehold interest and have joined forces with two of the most established, long-term successful drillers in the country. That is a formula for success, and we are genuinely excited about the near term prospects for our company," stated Greg Franklin, VP Exploration.
