HOUSTON, Aug. 27, 2012 /PRNewswire/ -- Rio Bravo Oil, Inc. (OTCBB: RIOB) (" Rio Bravo" or the "Company"), a domestic oil company based in Houston, TX, announced today that it has begun drilling operations on its leasehold in Luling, Texas. The Company recently completed a lease trade with Eagle Energy Trust (EGL-Un.TO) which allows for the extension of a horizontal well across the front of its D.G. Tiller leasehold, located on the Salt Flat Field. The Company then filed for and has received a permit to drill the D.G. Tiller 4H well into the Edwards formation. Drilling on the well is scheduled to commence in October 2012. In addition to the horizontal well, the Company has also begun recompletion of four of its existing Austin Chalk wells. The Company's plan is to drill several new wells on its acreage in close proximity to existing Edwards production, and then to evaluate the results. The work on the D.G. Tiller 4H well is consistent with the Company's business plan. The Company believes this approach may provide valuable information that may enable Rio Bravo to access significant proved oil reserves associated with its leasehold. Additionally, Company management believes the results from this initial drilling program may provide the basis for guiding the Company's future development plans. Rio Bravo hopes to report initial results from this drilling program in the early part of the 4 th quarter. Management CommentsRio Bravo's CEO, Tom Bowman, commented, "Development of the Edwards formation has continued with strong results in the Luling Area. Rio Bravo is now positioned to potentially realize value by demonstrating results on the DG Tiller 4H. We continue to define new locations, and will initiate new well permits to expand the drilling program upon completion of the DG Tiller 4H." About Rio Bravo Oil, Inc.
