Energy XXI to boost Main Pass 61 oil output

By OGJ editors
HOUSTON, Oct. 13
-- Three development wells, one of which found a new oil pay zone, are to be completed shortly in Main Pass 61 oil and gas field in the Gulf of Mexico off Louisiana, said Energy XXI (Bermuda) Ltd., Houston.

Energy XXI, field operator with 50% working interest, said an exploration tail for the CY-2 horizon at the MP 61 C-9 well cut 10 net ft of high quality oil below 8,000 ft true vertical depth, proving the existence and trapping of hydrocarbons below the main field pays. It plans to pursue the CY-2 and other deeper horizons with future drilling.

Logs at the C-9 well also indicate a greater-than-expected 122 net ft of oil pay in the BA-4AA1, BA-4AA2, BA-4AA2B, and J-6 sands at 7,145-7,810 ft TVD. TD is 9,000 ft TVD. The company plans to complete the J-6 sand in November. The other three sands represent proved reserve bookings and recompletion opportunities after J-6 depletes.

Logs at the A-11 well indicate 61 net ft of J-6 oil pay, also for completion in November. TD is 7,386 ft TVD.

Logs at the A-10 well indicate 45 net ft of hydrocarbon pay in J-6 in an updip attic area and with a gas-oil contact near the top of the sand. The company sidetracked A-10 away from the gas, drilled to 7,187 ft TVD, and found the J-6 full to base with 73 net ft of oil pay. It is to be completed by November.

Meanwhile, the South Timbalier Block 21 No. 128 well was reconditioned in the D-7 sand at 11,400 ft TVD and went on production Sept. 13 at a net 1,400 boe/d, 75% oil. Energy XXI is operator with 100% working interest, 83.3% net revenue interest.

The company recompleted the No. 75 well in the Rob E sand at 9,300 ft, and it came on line Oct. 6 at 700 boe/d net.
