Scottish oil and gas exploration and production company Cairn Energy has confirmed heavy oil from its Juby Maritime-1 (JM-1) well offshore Morocco.

Cairn operates the JM-1 well and has a working interest of 37.5%.
The company drilled the well, which reached a total depth of 3,711m TVDSS, to evaluate Upper Jurassic and Middle Jurassic objectives, then plugged the well and abandoned it without testing.
Over a gross interval of 110m as originally tested in the 1968 MO-2 well, located some 2km from JM-1, the well has confirmed the presence of heavy oil in the Upper Jurassic section.

By GlobalDataIn order to correlate the core and log data from JM-1 with other wells on Cap Juby, work is underway to evaluate the extent of moveable hydrocarbons and the method to further conduct assessment.
According to the company, the Middle Jurassic objective was encountered with limited primary porosity, while well logs and side wall core assessments will continue.
Located in the Sangomar, Sangomar Deep and Rufisque blocks, offshore Senegal, the next well in the company’s planned exploration programme will be ‘FAN-1’.
The well will target multiple stacked structural and stratigraphic fan closures that are interpreted as trapping various thick and quality clastic reservoirs.
