Gulfsands strikes oil in Syria

Nov 19, 2008 01:00 AM

Gulfsands has announced an oil discovery at the Yousefieh-1 well in the Gulfsands' operated Block 26, Syria.
The Yousefieh-1 well, located approximately 3 km from the Khurbet East Early Production Facility in Block 26, Syria, has encountered 63 meters of net oil pay in the target Cretaceous reservoir system and flowed oil to surface under natural flow at approximately 900 barrels of oil per day (boepd).

Yousefieh-1 well was drilled to a total vertical depth of 2,139 meters and encountered the target Cretaceous reservoirs at a slightly shallower depth than the pre-drill prediction and based on preliminary wire-line log evaluation, the well encountered an oil column of approximately 64 meters, with approximately 63 meters of net oil pay and average porosity of 18.6 %.
A drill stem test (DST) was conducted over the top 19 meter interval, flowing oil to surface under natural flow and through a 48/64 inch choke, at an average rate of approximately 900 bpd over a 3 hour period with no water produced. While preparing for the main flow period of the DST, the well produced, with the assistance of gas lift, at an average rate of approximately 1,450 bpd through a 95/64 inch choke over a 3 hour period. The preliminary results of the test indicate very good reservoir permeability.

Preliminary well site analyses indicate the oil gravity is approximately 23 degrees API, similar to the on-site analysis carried out upon discovery of oil at KHE-1. Core recovery operations were successfully completed over the entire reservoir interval and the information obtained from these cores, together with the wire-line log information and results of the DST will provide valuable information for the further appraisal of this discovery.
The Yousefieh-1 well was an exploration well designed to evaluate a stratigraphic trap in this portion of Block 26 unlike the structural trap of the Khurbet East Field. The company is currently preparing plans to undertake an extensive 3D seismic data acquisition program to assist in the delineation of leads and prospects in the areas surrounding the Khurbet East Field and the Yousefieh-1 discovery.

The Yousefieh-1 well will now be suspended and the rig moved to the Khurbet East Field to drill a delineation well at the north end of the Khurbet East Field with the aim of establishing the oil water contact and also with the potential to be used later as a water disposal well. A more extensive production testing program over the reservoir section of the Yousefieh well is expected to commence in the next few weeks.
Gulfsands' CEO, Ric Malcolm, commented, "The discovery of oil at Yousefieh-1 in a new play-type is an exciting and significant outcome for the company and provides strong encouragement for future exploration."

"This is the second oil discovery to be made in Block 26 within two years and demonstrates it's very prospective nature. The first discovery at Khurbet East is consistently producing at high rates through the early production facility and we are proud of our achievement in having produced more than one mm barrels of oil since production commenced back in July."
"The close proximity of the Yousefieh oil discovery to Khurbet East, together with the high quality reservoir encountered, provides encouragement for an early declaration of commerciality on this discovery."
