Tethys Oil says that a gravity-magnetic survey, and geology field work have started on its Bouanane reconnaissance license in Morocco. Tethys, as the license operator, has contracted a geophysical survey of gravity and magnetic data acquisition over a 1,536 square kilometer area. In addition, Tethys personnel along with ONHYM (Office National des Hydrocarbures et des Mines) geologists have started re-examining the geology at the surface, and collecting rock samples for source rock and reservoir properties.
The Department of Mining Exploration of the Morocco government's ONHYM is the contractor for the gravity-magnetic survey. The gravity data acquisition is carried out at two kilometer intervals along lines that traverse the license. Every 500 meters along these lines magnetometer measurements are taken. Over the coming six weeks the crew will make 429 gravity measurements and over 1,700 magnetic measurements, to cover the 1,500 square kilometer survey area.
The purpose of this survey in the Bouanane license is to further help in defining the extent of the Tafejjart prospect/structure, and the depth of the deepest possible reservoir targets. This survey will complement the existing seismic data over the main prospect of Tafejjart, especially to the northeast where there is a lack of seismic lines. Additionally there are other parts of the license without sufficient seismic coverage and where other prospects are expected.
