4D Technology

Our 4D seimic monitoring technique gives a volumetric 3D view of the drainage within each reservoir over time. In the L sand for example, red in the 1988 difference image (left) indicates gas is present. Blue in 1992 (right) records the drainage of the gas and its replacement by water in the reservoir. Bypassed oil (in the green) is predicted to be along the property line between the blocks where operators do not yet have wells placed.
