Matagorda Island is located in Calhoun County, Texas. In past years, the island has not been explored and drilled for oil and gas because the surface had been purchased by the federal government in 1941 and converted to a military reservation.
Several gas fields that are productive from the Miocene formation surround the island. Because gas has been produced from these fields, it was assumed that gas would be trapped in appropriate structures on the island. However, the results of drilling for oil and gas on Matagorda Island have been nonproductive and disappointing. Potential reservoir sandstones in the middle Miocene and the top of the massive Miocene sandstone section offer the best possibility for future gas production from stratigraphic-structural traps on the island.
