The results of Circle Oil’s KAB-1bis well on Morocco’s Sebou are in and unfortunately for the company the well was not as successful as it had been hoping for. The well was targeting the Miocene Guebbas sands from the KAB-1 well, however they were absent in this well.
The 2010 KAB-1 well had encountered gas shows in the target Miocene Guebbas sands, but problematic swelling clays created borehole instability and the well could not be logged or tested. KAB-1bis had the same target sands and was drilled with an adapted mud system to minimize drilling problems in a slightly more updip location. The primary target Guebbas sands were absent down to a TD of 1,410 meters MD and Circle decided to plug and abandon the well.
The lack of Guebbas sands in the KAB-1bis indicate the gas shows encountered in the Guebbas sands in the KAB-1 well were of a very limited extent.
The rig has been released to complete and test the SAH-W1 well on the western area of the Sebou Permit. The SAH-W1 well encountered three gas bearing Guebbas sands, but could not be completed as a non-standard 4.5 inch liner was needed. It is planned to produce the three zones sequentially from the bottom up, where the highest pressure is present.
Commenting on the results of the KAB-1bis well Steve Jenkins, Chairman, said: “Although the result of the KAB-1bis well is disappointing, the well was targeting a smaller incremental accumulation. We look forward to the results of testing of the SAH-W1 well and continuation of the drilling campaign on the Sebou and LallaMimouna Nord Blocks.”
