The new discovery Ozoris-4 well encountered a 90-foot gross sand column with 67 net feet of pay in the Jurassic Upper Safa formation, testing at a daily rate of 29.4 million cubic feet (MMcf) of gas and 1,775 barrels of condensate on a one-inch choke. Perforations were in two zones between 12,828 feet and 12,860 feet and between 12,896 feet and 12,912 feet.
"This is the first productive Upper Safa sand encountered on the west side of the Khalda ridge," said G. Steven Farris, Apache's president and chief executive officer. "The discovery of stratigraphically trapped gas-condensate in Upper Safa sands in the Ozoris-4 opens up a large new play in the Shushan Basin, north of the Qasr high and west of the Khalda Ridge fields."
Ozoris-4 also encountered 171 net feet of oil and gas-condensate pay uphole in the Cretaceous Kharita and Alam El Bueib sands. In addition, the well penetrated approximately 100 feet of poorly developed Lower Safa reservoir, confirming the seismically defined northeastern limits of the Qasr field.
Ozoris-4 has been temporarily shut in to allow production of oil encountered in the Alam El Bueib and Kharita reservoirs. The Upper Safa will be appraised by future Ozoris wells.
Ozoris-4 is located on the flank of the Qasr structure, 1.4 miles north of the Qasr-1X discovery well. Apache operates the Khalda Concession with a 100% contractor-interest.
Total revenue to both parties under the 25-year Qasr field agreement is approximately $5.5 billion. Apache owns a 100% contractor interest in the Khalda Concession.
"The Qasr-1X discovery was completed in July 2003 after Apache logged 606 feet of net pay in a 670-foot gross hydrocarbon column. Two appraisal wells, the Qasr-2X and Qasr-3X, add to our confidence regarding the ultimate size of the structure," Farris said.
"Principal terms include supplying 300 million cubic feet (MMcf) of gas per day to the Egyptian market, which more than doubles our current production of 275 MMcf per day," said G. Steven Farris, Apache president, chief executive officer and chief operating officer. "All told, Apache has a market for 650 MMcf of gas per day in Egypt.
