Joint Geophysical Imaging

Research Objectives
The objective of the Joint Geophysical Imaging project is to ultimately
develop formal joint geophysical imaging algorithms for simultaneously
inverting different types of geophysical data—to find a common,
self-consistent earth model. The initial stages of this work have
concentrated on demonstrating a methodology for combining time-lapse
changes in electric conductivity and compressional- and shear-wave
velocity with a detailed rock-properties model, to produce quantitative
estimates of the change in reservoir pressure and fluid saturations.
