In deep water, the objective is to maximize prospect knowledge and reduce technical and economic variables. Deeper waters are often accompanied by deeper prospects, often hidden below complex and seismically opaque geological structures. Innovative acquisition techniques and new workflows enable geophysicists to better characterize the uncertainty based on better images of the subsurface.
Acquiring high-quality seismic and well data is the starting point for all reservoir simulations. Complementary data conditioning, processing, and workflows are critical for obtaining optimal results from subsequent reservoir modeling and forecasting.
In deep water, it is necessary to identify as much detail as possible below overlying geology such as carbonate rocks or laminated sands below salt, and basalt formations. The best seismic acquisition geometry needs to be chosen to deliver the highest quality image.
Data from all disciplines need to be assembled to optimize predictions. A multidisciplinary software platform provides an interpretation environment unified with geology, reservoir modeling, and reservoir engineering domains.
High-quality seismic data enable early planning using techniques based on acoustic and elastic inversion, rock physics analysis, and property modeling.
Pore pressures that may be encountered during drilling can be assessed early with seismic data. Plan wells based on pore pressure prediction using fit-for-purpose seismic velocities.
