Abstract:

Adaptive multiscale estimation of a spatially dependent diffusion function is considered. When utilizing pressure data, the method has been successful in identifying coarse-scale structures of the diffusion function. In this article the method is used with pressure and fluid rate data as information sources. The estimate is expected to be improved when additional data are included. However, this expectation is not always met, and in some cases the simultaneous use of these data types in the estimation might even cause problems. The reason for the lack of improvement is investigated together with methods for successful estimation utilizing pressure and fluid rates.
