Abstract
The optimization of a hydrocarbon reservoir performance depends on having an accurate characteristic map of the reservoir. This map’s construction requires a reasonably accurate match to the historical reservoir performance, such as pressure and production rate. However, matching the historical data is a costly process that will most likely lead to a non-unique reservoir model. This article developed an algorithm that jointly inverts for the reservoir (permeability) and seismic velocity simultaneously using a cross-gradient method. The results are a more accurate reservoir model and an improved seismic image. Enforcing the structure constraint through the cross-gradient approach allowed the inversion to converge fast.
