Located within the western central area of the Sebou Permit about 4km to the south of the main gas gathering station, the well has been drilled to a total depth of 1,232m.
The well encountered 9.7m of total net gas pay in a number of levels within the Hoot and Guebbas sands.
The well will now be completed by the company for future production.
Circle Oil CEO Chris Green said: "We are very pleased to have another successful discovery in our Sebou permit and have proven additional reserves for potential gas production. This is the second well of a six well programme to be drilled with our partner ONHYM in the Sebou permit and is coupled with another six well programme in the Lalla Mimouna permit."
The company will now move on to drill the KSR-12 well, which will be third in the Sebou program.
Circle Oil has assets in the Rharb Basin in Morocco, the Ras Marmour permit in southern Tunisia, the Mahdia permit offshore Tunisia and the Zeit Bay area of Egypt.
