Feasibility and Project Development Expertise
MHA has expertise in projects which involve investigating the feasibility of developing new gas storage projects, as well as the evaluation of the critical operating parameters necessary to optimize field performance of existing underground gas storage reservoirs. We are experienced in follow-up projects which take design specifications from feasibility studies, reservoir simulation models, and surface facility evaluations for implementation in field operations.
Detailed examples of MHA experience:
- PG&E Compressed Air Energy Storage Project (CAES), Sacramento Basin, California: MHA built, calibrated, and utilized reservoir simulation models to support a feasibility study to repurpose a depleted natural gas reservoir for air storage in a CAES application. The results of the project helped in developing best practices and accelerate the market readiness of the technology in the United States. The project was funded by the United States Department of Energy (DOE), the California Public Utilities Commission (CPUC), and the California Energy Commission (CEC).
- Dötlingen Field, Germany: The Dötlingen gas storage field is located in northern Germany and contains approximately 240 Bcf of gas. Field performance had been deteriorating over the previous decade due to hysteresis and gas losses as a result of natural fractures and faults. MHA conducted detailed geologic and reservoir simulation studies, coupled with a 3D seismic volume, which identified the position of the lost gas, allowing us to characterize the field performance and outline intervention strategies to prevent further deterioration of field performance.
