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.
