Tanganyika Reaches Final Depth on Syrian Well

Tanganyika Oil Company reports on the progress of its horizontal drilling program on the Oudeh Field in Syria. The OD #136 horizontal well reached its final drilled depth of 2,842 meters on May 24, 2004 and will now undergo an extensive testing program with results expected in mid-June. Drilling went smoothly and according to schedule.

The second horizontal well (OD #137) has spudded from the same drill pad in the opposite (westerly) direction from OD #136, utilizing the same drill rig. The well is currently drilling ahead in surface basalt. The first casing point is scheduled at 450 meters. As with the first well, the OD #137 well will be drilled vertically to a depth of 1,100 meters at which point it will be kicked off horizontally for around 1,200 to 1,500 meters with a total drilled length of up to 3,000 meters. The well is expected to take 35 to 45 days for drilling and completion.

The initial program has scheduled two wells to be drilled into the top section of the Shiranish reservoir. However, a multiple well drilling pad has been constructed which has the capacity to accommodate the drilling of six wells, which should allow for efficient reserves recovery in this sector of the field.

Horizontal drilling technology offers the potential to significantly increase well productivity and reserve recovery by increasing the volume of the reservoir exposed for production from each well. Upon full development of the Oudeh Field, production levels are expected to reach 30,000 bopd.
