Abstract
Summary
We have developed an optimization methodology to consistently integrate petrophysical evaluations and the construction of rock physics models using multiple wells. This approach allows exploring the different parameters/coefficients used both for the evaluation and rock physics model, while ensuring complete repeatability and traceability of results. It has been used to build a rock physics model for the Chalk member in the Danish North Sea area, allowing us to cover the transition from clean limestone in the upper-Cretaceous to the shale-rich lower-Cretaceous limestone. During this process, some of the initial petrophysical evaluations were also updated.
