International oil exploration company Circle Oil has completed drilling at its CGD-10 exploration in the Sebou permit, Morocco.

The company confirms a discovery in the lower Guebbas sequence with the well testing gas at a sustained rate of 3.9MMscfd from the primary target using a 24/64in choke. The perforated interval of 889.3m to 897m has a calculated net gas pay of 3.3m.

The secondary target of between 847.5m and 854.5m has a calculated net gas pay of 2m and testing of this interval will be carried out at a later date. The well is being completed as a potential producer.

A full technical evaluation of all the results of the well is underway. This will allow for forward planning as a precursor to further assessment of the resource, including conducting an extended well test to give a more complete estimation of the reserves, Circle Oil said.

The drilling rig will move to start drilling the final well of the planned six-well drilling programme in the area.

The Sebou permit lies to the north-east of Rabat in the Rharb basin in Morocco. The Rharb basin is located in the external zone of the Rif Folded belt.
