Large Cris R Massive gas find indicated in Vermilion

By OGJ editors
HOUSTON, July 19
-- A group led by PetroQuest Energy Inc., Lafayette, has made a large indicated gas discovery in the primary Cris R Massive objective in Vermilion Parish, La., just southwest of Tigre Lagoon field.

Due to the projected size of the reservoir, PetroQuest said, it is evaluating a multiwell delineation program to accelerate development of the discovery. The company said it should exhibit a stable production profile analogous to PetroQuest’s 2008 Pelican Point gas-condensate discovery farther east.

Petroquest said the well on the La Cantera prospect reached a depth of 18,550 ft and logged 176 ft of highly resistive sand in Cris R. As a result of stuck pipe in the bottom 550 ft of the well, the company was only able to obtain porosity information in the upper part of the logged sands that confirmed 37 ft of net commercial pay.

The company is preparing to sidetrack the well in to evaluate the entire sand package and test other objectives as deep as its proposed true vertical depth of 19,300 ft.

PetroQuest has a 16% net revenue interest, and Stone Energy Corp., Lafayette, has a 33% working interest in the well, also called LaPosada. The companies expect to be able to start production around yearend or in early 2012.

The well represents the second discovery Stone has made in the South Louisiana deep gas play following South Erath 5 miles northwest of La Cantera. Stone is participating in another onshore deep gas exploratory test at Lighthouse Bayou in Cameron Parish, La., that is drilling at 20,000 ft enroute to 25,000 ft.

Stone has also identified deep gas prospects on the Gulf of Mexico shelf, where the company is the third largest lease owner, and is maturing the prospects for its 2012 and 2013 drilling programs.
