Our activity in Egypt began in 1994 with our first Qarun discovery well, and today we are one of the largest acreage holders in Egypt’s Western Desert. At year-end, we held 9.8 million gross acres, with gross oil production of 198,000 barrels per day and gross natural gas production of 912 million cubic feet (MMcf) per day in 2013, or 90,000 barrels per day and 356 MMcf per day net to Apache’s consolidated holdings. Although 3 million gross undeveloped acres expired in January 2014, we continue to pursue longer term extensions on areas we believe provide attractive growth opportunities. Of our remaining acreage, 72 percent is undeveloped, providing us with considerable exploration and development opportunities for the future.
A significant discovery was made by the Ptah-1X in the Shushan Basin that targeted a separate culmination along the same Berenice fault block. The well encountered significant pay in the AEB-3E and Paleozoic Shifah formations. The Ptah-1X began producing from the Paleozoic on a restricted choke at a rate of over 2,100 Bo/d.
