Calvalley Petroleum Spuds Hiswah-3 Appraisal Well



Calvalley Petroleum reports that the modifications to the drilling rig have now been completed and it has spudded the Hiswah-3 appraisal well in Yemen. Hiswah-3 is the first of three planned appraisal wells. Each well will be comprised of a vertical wellbore to gather reservoir data, and a horizontal sidetrack to test the productive capability of the fractured limestone reservoirs of the Saar Formation. It is expected that this first well will take approximately one month to drill and test.

Calvalley Petroleum is operator of Block 9 in Yemen.
