f Production Characteristics of Sheet and Channelized Turbidite Reservoirs, Garden Banks 236 Field, Gulf of Mexico

The Garden Banks 236 Field is located in 700 feet (213 m) water depth in the northern Gulf of Mexico, and is situated about 150 miles (240 km) from Lafayette, Louisiana (U.S.A.). Dry gas is produced from middle Pleistocene (lllinoian) turbidites situated on two separate present-day geologic structures. This paper will address the production characteristics of the Block 191 structure which began producing in 1993 and has produced over 210 BCF cumulative gas to date from turbidite sheet (4500' Sand) and channel (8500' Sand) sand reservoirs. Understanding the distribution of shale breaks within both reservoir types is critical to managing the reservoirs because the shales compartmentalize gas production and control water encroachment through the gas reservoirs.
