Flatrock field in Gulf of Mexico has potential to grow
The Flatrock field in the Gulf of Mexico shelf is producing 200 mm cfpd of gas from four wells, has more than 350 bn
cf of proved reserves by independent estimate, and has the potential to grow, said McMoRan Exploration, New
Orleans.
Individual well rates vary depending on porosity, permeability, pressures, and hydrocarbon column, but the primary
Miocene Rob-L reservoir has achieved the highest output at more than 100 mm cfpd.
The No. 4 well, which tested at 124 mm cfpd in October 2008, is making 60 mm cfpd with a targeted gross rate of 90 mm
cfpd. The field's Operc section is producing in two wells and being completed in a third well, and the No. 6 well
might penetrate the upper Gyro section sands.
The No. 5 development well logged 155 net ft of Rob-L and Operc pay, is being completed in Operc, and is due on line
in this year's first quarter.
The No. 6 delineation well on SMI 217 is drilling below 16,000 ft towards 19,700 ft. It logged 40 net ft of Rob-L
pay.
The field was a July2007 discovery in 10 ft of water on South Marsh Island Block 212.
