DNO updates drilling operations

The Tawke # 12 well was previously drilled to the top of the Cretaceous reservoir section using one of the larger drilling rigs, and thereafter temporarily abandoned. The well was re-entered by the new carrier rig and the Cretaceous reservoir section has been now been penetrated. A total of 131 meters of cores were taken in the Cretaceous and the observations while drilling and coring confirm oil in the reservoir as expected.

The well has now been deepened into the top of the Jurassic section and oil shows have been observed while drilling. The Jurassic section represents another reservoir target which will be further evaluated within the Tawke area as well as in the other areas of the PSA’s.

The Yaalen # 1 exploration well commenced drilling on 4 January 2008 and is the first exploration well drilled by DNO on this license. The well has been drilled to a depth of approximately 2,550 meters. Oil has been observed while drilling through several intervals, and oil was also retrieved from wire line fluid sampling both in the Qishn sandstone as well as in the Kohlan sandstone immediately above the Basement.

The forward plan is to drill a Basement section before temporarily abandon the well. The rig will thereafter move to Block 32 to drill one exploration well and a Godah development well before returning to Block 47.
