Schlumberger has introduced its GeoSphere reservoir mapping-while-drilling service. The new technology reveals features in subsurface beddings, and fluid contacts at the reservoir scale, to optimize well landing operations, steering capabilities and mapping of multiple boundaries, using new deep-directional resistivity measurements enabled by proprietary real-time interpretation techniques. With a deep range of investigation that extends more than 100 ft from the wellbore, drilling teams can use the GeoSphere service to reduce drilling risk and accurately land wells, resulting in the elimination of pilot holes. The real-time reservoir mapping-while-drilling service also enables the positioning of wells within target reservoirs, away from fluid boundaries, leading to increased reservoir exposure, as well as allowing geoscientists to refine their seismic interpretation, and geological and structural models.
