Unconventional hydrocarbon reserves substantially surpass those of conventional resources and therefore are extremely economically attractive. However, exploration and production of unconventional reserves is challenging. This paper demonstrates that one can observe significant induced polarization effects in shale reservoir rocks, which can be used in exploration for unconventional reserves. T...

Ensemble Kalman Filter (EnKF) uses a randomized ensemble of subsurface models for performance estimation. However, the complexity of geological models and the requirement of a large number of simulation runs make routine applications extremely difficult due to expensive computation cost. Grid computing technologies provide a cost-efficient way to combine geographically distributed computing res...

Currently economic growth in a New York City watershed is limited due to phosphorus concentrations exceeding standards. The phosphorus concentration in the Cannonsville reservoir in New York State must be reduced to safeguard New York City’s drinking water supply, and to enable economic growth to continue in the reservoir’s watershed. In Delaware County, where the reservoir is located, the prob...

We quantify natural methane hydrate reservoirs by generating synthetic seismic traces and comparing them to real seismic data: if the synthetic matches the observed data, then the reservoir properties and conditions used in synthetic modeling might be the same as the actual, in-situ reservoir conditions. This approach is model-based: it uses rock physics equations that link the porosity and min...

Large-Scale Three-Dimensional Geomechanical Modeling of Reservoirs: Examples from California and the Deepwater Gulf of Mexico — Cost-effective improvements in the technology needed to develop and manage reservoirs in challenging environments require an increase in our understanding of geomechanical behavior. The local stresses relevant to reservoir-scale processes are strongly affected by strat...
