Geophysics has become an integral part of field production activities. Geophysical data frequently are used to solve specific reservoir problems, to monitor saturation and pressure changes, and to create and adjust reservoir models. That situation represents a significant change in the past decade. Prior to that, geophysical operations typically were completed before any significant production activity occurred. Furthermore, as development wells were drilled, the exploration teams dispersed to new projects. The increase in geophysical applications during production has been brought on by the aging of the existing inventory of oil fields and the volatility of oil prices. The petroleum industry recognizes the need for a dramatic improvement in its ability to characterize the distribution of reserves and the flow paths that choke hydrocarbon recovery rates or lead to early water breakthrough.
