Tethys Oil: Kunooz-1 exploration well drills to final depth

The exploration well Kunooz-1 on Block 58 onshore Sultanate of Oman has drilled to its final depth of 3,923 m. The well targeted the Buah and Khufai formations as its primary targets with the Birba formation as its secondary target.

Wireline logging of the Birba and Buah formations indicated an approximately 500 me gross thickness of fractured dolomitic limestone and low matrix porosity. The reservoir section was drilled with total drilling fluid losses with no cuttings to surface. It indicates high reservoir permeability but provided limited data availability for while-drilling evaluation of hydrocarbon potential. A flow test is required to confirm a possible hydrocarbon potential in the Birba and Buah formations. No sufficient data was collected from the deeper Khufai formation due to operational challenges.

Further well completion and testing will commence to evaluate the well’s flow performance. The well testing program includes an open hole completion of the Birba and Buah formations, alongside further analysis of collected data. The well testing program is expected to be completed in approximately four weeks.
