Practical Applications of Time-lapse Seismic Data

“…With the expectation of continuous data being available through permanent downhole sensors and surface or seabed seismic, the workflow becomes one based on process control -repeated measurement, prediction, and verification (Figure 2b), with a focus on relative changes rather than on absolute values of saturation, pressure, and other reservoir properties Mochizuki et al, 2006). Combined with smart wells, such a workflow can result in faster feedback and tighter control, which mean optimization in real time.…”
