Block S-1 (25.0% working interest) An Nagyah #17, which commenced drilling on August 28, 2005, reached a total depth of 2,066 meters and was completed as a producing oil well after flowing at a stabilized rate of 3,250 barrels of light (43 degree API) oil per day and 1.8 million cubic feet of gas per day on a 48/64 inch choke. The An Nagyah #17 well encountered the Lam A sandstone reservoir and was completed in a 575 meter horizontal section. The well is now being pipeline connected to the An Nagyah facilities.

The drilling rig is preparing to move to the next drilling location at An Nagyah #18. The An Nagyah #18 well is planned as an 800 meter horizontal well in the Lam B sandstone of the An Nagyah field, adjacent to An Nagyah #3. The Lam B sandstones were initially discovered in the An Nagyah #3 vertical well where they had a net pay of 5.0 meters and a tested oil column of more than 50 meters. The An Nagyah #3 Lam B zone tested at a rate of 240 barrels of light, sweet (42 degree API) oil per day. The core and test data indicate the Lam B reservoir has less porosity and permeability than the Lam A reservoir therefore a horizontal well is being drilled at An Nagyah #18 to enhance production.

Block 32 (13.81% working interest) The Balan #1 exploration well commenced drilling on October 1. The well is located approximately 11 kilometers north of the Tasour field. Balan #1 will test for three potential oil accumulations, the Qishn sandstone, the Saar carbonate and the fractured Basement. The well is expected to finish drilling by mid November.

A second rig is planned to start drilling on another exploration location at North Hemiar by the end of October. The North Hemiar well location is approximately 7 kilometers east of the Tasour field and will test for a potential oil accumulation in the Qishn sandstone.

Block 72 (33% working interest) A seismic acquisition program consisting of 255 km of 2-D data has commenced on Block 72. The acquisition and processing of the data is anticipated to be completed in early 2006. A two well exploration drilling program is planned for late 2006.
