Houston American Energy Updates Drilling Plans HOUSTON, Oct. 3, 2013 — Houston American Energy Corp. (NYSE MKT: HUSA) today provided an update with respect to its near term drilling plans. In addition to previously announced plans to participate in drilling a 10,000′ test well in Pecos County, Texas, Houston American announced that it has agreed to participate in the drilling of test wells on three prospects, each of which is presently anticipated to occur before year-end 2013. The planned wells, and Houston American’s interest in the prospects, are as follows: * In South Texas, a 4,000′ test of the Lower Hockley Sand is planned targeting potential oil pay. The prospect is within a 179 acre lease block supported by 3-D seismic and is a look-a-like to a successful well nearby. A second similar prospect has been identified on the lease block. Houston American will own a 7.2% working interest in the well and acreage. * In Jefferson Davis Parish, Louisiana, a 7,000′ test of the Cris H stringer and Cris H sand is planned with the objective of gaining structure on existing productive oil wells. Houston American will own a 10.9% working interest in the well before payout and a 9.375% working interest after payout. * In Iberville Parish, Louisiana, a 13,500′ test of the Cib Haz Sands is planned. Successful wells in surrounding acreage have come on production at rates averaging approximately 800 barrels of oil per day with associated gas production. Houston American will own a 3% working interest in the well and 618 acre lease block. Houston American has budgeted approximately $700,000 for these prospects to be funded from its existing working capital John F. Terwilliger, Chairman and CEO of Houston American Energy stated: “We have been actively searching for domestic opportunities and have found a number of interesting conventional exploration prospects that we believe have been overlooked while other operators are focused on shale plays. A number of other prospect opportunities are in our project pipeline and we hope to finalize arrangements to participate in one or more of those prospects in the near future. We are excited about these prospects and look forward to getting active with the drill bit here in the U.S.” About Houston American Energy Corp.
