Release Notes for MRST 2021b
Highlights of MRST 2021b
The new release comes with some improvements in functionality and minor bug fixes. In particular we would like to highlight the following:
With the new network-models module you can create reduced simulation models that represent the reservoir as a network of 1D flow paths connecting wells. The resulting network model can subsequently be calibrated to match observed or simulated well responses using an adjoint-based or ensemble-based method. The interwell connections can be set up in different ways: all-to-all, injectors to producers, user prescribed, or identified by flow diagnostics pre- or postprocessing of an underlying simulation model. The functionality of the module is demonstrated on the Egg, Norne, and SAIGUP cases.
The ad-micp module has been contributed by David Landa-Marbán and co-authors at NORCE. It extends the solvers found in ad-core and ad-blackoil with capability for simulating microbially induced calcite precipitation (MICP) applications. MICP is a new and sustainable technology which utilizes biochemical processes to create barriers by calcium carbonate cementation; therefore, this technology has a potential to be used for sealing leakage zones in geological formations. The main mechanisms in the conceptual model are as follow: microbial solution is injected which results in microbes attaching themselves to the pore walls to form biofilm, growth solution is injected to stimulate the development of biofilm, cementation solution is injected which is used by the biofilm for production of calcite, and the calcite reduce the pore space which in turn decreases the rock permeability.
