摘要

Drilling through complex reservoirs can be extremely challenging, since pre-well geological models are often limited to the resolution of seismic data. Even with nearby offset wells against which to correlate, complex geology by definition has significant variations that cannot be fully anticipated before drilling. Advances in directional LWD resistivity measurements have compensated for these pre-well limitations through improved real-time geosteering, by providing discrete measurements and distance to the formations above, below and to the sides of the sensor while drilling horizontally or at high-inclination angles through the reservoir.
