SBL is a new and expanding exploration technique with the potential of acting as a direct hydrocarbon indicator. This technique was pioneered by Statoil in close collaboration with NGI. The technology was later transferred to the commercial company EMGS, run by former members of Statoil's scientific staff. EMGS now plays a very active role in this rapidly growing market as a contractor. SBL is still a very new technique. The continuing success of the technique relies on an improved understanding of the el ectric earth model combined with the development of optimized and cost-effective exploration procedures.
The main activities of the project are:
(i) Efficient-medium representation
Develop an efficient-medium representation of a complex reservoir zo ne. The theoretical study will be supplemented by medium-scale (meter range) laboratory model tests at NGI's own test facility.
(ii) Design and development of modeling algorithm
Develop a 2.5D PDE (partial differential equation) solver that integrates the efficient-medium representation of the reservoir zone. We will focus on the dispersed-clay, structural-clay and laminar-shale cases. Hence, the modeling software must handle the special case of anisotropy denoted transverse-isotropy (TI).
(iii) Impl ementation and test of modeling tool
Numerical implementation of the complete system, including the efficient-medium builder and the modeling algorithm (PDE solver).
The feasibility of the complete modeling tool will be tested in collaboration with th e Norwegian oil industry, employing EM-wave and logging data from a North Sea reservoir.
We will, during the course of the project, arrange two workshops with participants from oil companies, international research institutions, and Norwegian research au thorities.
