Abstract
The primary goal of the present work is evaluation and comparison of vertical and horizontal well placements and their impact on the power output of a CPG (CO2 Plume Geothermal) system. Performances of vertical and horizontal wells are evaluated for a repeated five-spot pattern. Six numerical models were developed in MOOSE (Multiphysics Object Oriented Simulation Environment), tested and compared against each other and a benchmark study. Simulations show that the reservoir will respond differently to different well configurations, with buoyancy playing a major role in its response. The study concludes with recommendations on ways to improve the accuracy of present models and directions for future research on optimal well placement for CPG systems
