The geology of Saudi Arabia is covered by variable and complex overburden, which makes it difficult to image subsurface reservoirs in some areas. Therefore, novel processing and Previous HitdataNext Hit Previous HitacquisitionNext Hit methods need to be developed that yield improvements to Previous HitseismicNext Hit images, while maintaining a cost-effective approach. Constructing scaled physical models, with the expected geological and geophysical characteristics of the problem areas, provides a low-cost means for testing and evaluating different Previous HitseismicNext Hit Previous HitacquisitionNext Hit and processing techniques. In 2006, Saudi Aramco commissioned the building of a physical modeling system in order to develop a capability to simulate the Previous HitseismicNext Hit Previous HitdataNext Hit Previous HitacquisitionNext Hit in various oil field and exploration target areas. This, in turn, would allow the Previous HitdataNext Hit, acquired with an emphasis on representing a complex overburden, to be processed with knowledge of ground-truth geology and geophysics. The system uses ultrasonic sources and receivers to simulate Previous HitseismicNext Hit Previous HitdataNext Hit Previous HitacquisitionNext Hit. The modeling system can record 16 receiver channels and is probably the most advanced automated recording system in the world. Land surveys are simulated by the receivers being in direct contact with the surface so that statics and other near-surface anomalies can be investigated. Previous HitMarineNext Hit surveys are simulated by adding water and moving submerged sources and receivers above the model. It is capable of simulating a wide range of vibrator and explosive source signatures with any receiver array configuration. Conventional 2-D, 3-D, 3C, walk-away VSP, cross-well tomography, and micro-seismicity can all be simulated. This presentation will discuss the unique recording capabilities offered by this physical modeling system, and review Previous HitdataNext Hit recorded to simulate Previous HitseismicNext Hit Previous HitacquisitionTop conditions over a typical Arabian Peninsula subsurface geology overlain by a complex overburden.
