DEVELOPMENT PRACTICES FOR OPTIMIZED MEOR IN SHALLOW HEAVY OIL RESERVOIRS
The objective of this research project is to demonstrate an economically viable and sustainable method of producing shallow heavy oil reserves in western Missouri and southeastern Kansas, using an integrated approach including surface geochemical surveys, conventional MEOR treatments, horizontal fracturing in vertical wells, electrical resistivity tomography (ERT), and reservoir simulation to optimize the recovery process. The objective also includes transferring the knowledge gained from the project to other local landowners, to demonstrate how they may identify and develop their own heavy oil resources with minimal capital investment. In the twelve to eighteen-month project period, three wells were equipped with ERT arrays. Electrical resistivity tomography (ERT) background measurements were taken in the three ERT equipped wells. Pumping equipment was installed on the two fracture stimulated wells and pumping tests were conducted following the hydraulic fracture treatments. All wells were treated monthly with microbes, by adding a commercially available microbial mixture to wellbore fluids. ERT surveys were taken on a monthly basis, following microbial treatments. Worked performed to date demonstrates that resistivity changes are occurring in the subsurface, with resistivity increasing slightly. Pumping results for the hydraulically fractured wells were disappointing, with only a show of oil recovered and an increase in well shut-in pressure.
