Portrush said that current production from the field is 1.6 million cubic feet of gas and 50 barrels of condensate per day.

Preparations are being finalized for the Mission River summer drilling program. Wells drilled to the Vicksburg formation will be drilled to approximately 8,700 feet. It is considered best to drill to the deeper formations, as the potential new reserves to be captured at depth reportedly exceed the potential reserves in the shallower formations.

The Mission River lease is being developed by McAlester Oil and Gas, and is located at the south-end of the town of Refugio, Texas. The field has multiple pays at depths ranging from 2,000 feet to 8,800 feet. Portrush has a 10% working interest in the field. To date ten wells have been drilled to varying depths and all ten wells have been productive.
