MIOGYP DEVELOPMENT WELLS, DEEP TEST FOLLOW AT CHALKLEY

The Chalkley deep discovery well has been successfully offset with four development wells, each capable of producing at sustained rates of 40 MMcfd. In addition, a deeper Miogyp reservoir was opened by the Transco Exploration Co. 1 TXP well. Drilled on a farmout from Exxon Co., U.S.A. about 2,500 ft southeast of the discovery well, it was completed in August 1991.
