NEW ORLEANS -- McMoran's Flatrock discovery intersected three additional hydrocarbon bearing zones in the Operc section while deepening the well to 18,100 ft (5,517 m), according to the company.
Wireline logs indicated 30 net ft (9 net m) of sands over a 120-ft (37-m) gross interval in one sand and log-while-drilling tools found 41 net ft (12 net m) over a 153-ft (47-m) gross interval in two sands.
McMoran says these three zones are deeper than the five zones previously announced in July, which contained 189 net ft (58 net m) of hydrocarbon bearing sands over a combined 364-ft (111-m) gross interval above 16,500 ft (5,029 m) in the Rob-L section as indicated by wireline logs.
In total, the well has encountered eight zones with 260 net ft (79 net m) of hydrocarbon bearing sands over a combined 637-ft (194-m) gross interval. McMoran plans to deepen the well to 19,000 ft (5,791 m) to evaluate additional targets in the Operc section.
The Flatrock discovery well is on OCS block 310 at South Marsh Island block 212 in 10 ft (3 m) of water. McMoRan operates the well with a 25.0% working interest.
