Cairn Energy PLC reported that its JM-1 well offshore Morocco has been plugged and abandoned without testing. The well commenced drilling in January and reached a total depth of 3,711 m. The stated objectives of Upper and Middle Jurassic were reached, the company said.
The JM-1 well confirmed the presence of heavy oil within a gross interval of 110 m in the Upper Jurassic section. This interval was originally tested in 1968 at the MO-2 well, which is 2 km from the JM-1 well. Cairn reported that reservoir quality and oil gravity in the Upper Jurassic across the Cap Juby structure will require further evaluation.
The company holds a 37.5% working interest in the JM-1 along with its joint venture partners, the Office National Des Hydrocarbures et Des Mines and Genel Energy. According to the company, work is continuing to correlate core and log data with other wells on Cap Juby to evaluate the extent of moveable hydrocarbons. Primary porosity and evaluation of well logs and side wall cores is ongoing for the Middle Jurassic section as well.
