Research

As a brief introduction, my current research is using a new hybrid inverse modeling method to solve a real project. Below is the description of the research. Problems: The Cheyenne Board of Public Utilities is planning to develop the Casper Aquifer in Belvoir Ranch as a sustainable groundwater resource. Based on the previously obtained geological and geophysical data, the Casper Aquifer has the potential to become the water supply resource if the uncertainties can be better understood, and these uncertainties include conductivity, location and rate of recharge, and aquifer boundary conditions. The purpose of this study is to solve the uncertainties in the project, identify the location of target drilling program, and apply the method to other project if it is efficient. Scopes: To accomplish this project, the study is divided to three stages, and each stage will cost approximately one year. The first stage is static model integration with Petrel which includes hydrostratigraphy, faults, and fractures. The second stage is dynamic integration and model calibration using hybrid inverse. The third stage is post-audit and captures zone analysis. In the last stage, a new set of dynamic data will be obtained, and by comparing the calibrated models and the new data, the feasibility of the calibrated model is tested. Then, the highest ranking calibrated models will be used for well capture zone analysis. The budget will be split to two parts: one part goes to the exploration and development of the Casper Aquifer, and the other part goes to the PhD student who will build the model for the project. Target: The study will finally lead to a new sustainable groundwater supply in Cheyenne area, and the successful model can be used to evaluate other hydrogeological environments in the States.
