Provide FE support for latest FE tools such as: –Image logs derived whilst drilling, pressure testing while drilling, azimuthal measurements while drilling. Providing wireline replacement in a real time environment. Aim is to develop greater FE competency and work more closely with client petrotechnical staff onshore
