\nExecutive Summary
\nThis report summarizes a reservoir simulation study on the CarbonSAFE Project ECO2S Kemper Regional Storage Complex to understand how it can be developed and operated to accept a yearly volume of 22.5 million metric tons of carbon dioxide, captured and transported from three power plants. These sources are the gas-filled units of Plant Ratcliffe (with 0.7 MMmt of annual carbon dioxide emissions) and Plant Daniel (3.0 MMmt\/yr), and the coal-fired units of Plant Miller (18.8 MMmt\/yr), totaling 22.5 MMmt\/yr of carbon dioxide or 675 MMmt over 30 years.
\nWith such a significant volume of CO2, this effort centered on how the plume would develop and how it may migrate, based on the current geological understanding. Of further interest was whether the plume size and direction could be minimized and\/or more quickly immobilized through active plume management using water cycling techniques. A base simulation model was developed utilizing the latest geological interpretation of the saline storage formations, the Lower Tuscaloosa Massive sand, the WashitaFredericksburg Dantzler and \u2018Big Fred\u2019 intervals, and the Paluxy. The data collected from the three Phase II wells were incorporated in the geological model for further refinement within the project site. Porosity-permeability transform functions were developed for these groups of reservoirs using log and core data.
\nThe base model contains 21 carbon dioxide injection wells, located on seven well pads. Each well on a given pad is perforated in only one reservoir group, Massive sand\/Dantzler (combined), Big Fred, or Paluxy zones. In other words, each reservoir group receives carbon dioxide through seven injection wells. If the total carbon dioxide daily injection rate were uniformly distributed among the three reservoir groups, the resulting carbon dioxide plume would be vastly different due to differences in rock properties, salinity, reservoir temperature and pressure. To get similar plume extents, different injection volumes were selected for each reservoir group. This arrangement resulted in the Massive sand formation getting the least and the Paluxy formations the most injection volume. The final carbon dioxide plume extent was approximately 55 square miles,
\nSensitivity analysis on horizontal permeability anisotropy and hysteresis trapping gas saturation shows their impact on the plume size, changing it by as much as 27% over the base model assumptions, 30 years after the end of CO2 injection. Water cycling was also studied in this model to see its impact on controlling the plume migration. Placement of water injection and production wells at a distance from the carbon dioxide injection wells and at different sides of the site were tested. Twelve water production wells (four assigned to each reservoir group) placed on four well pads would each extract 20,000 bbl\/day of water. Twelve injection wells then re-inject the produced water through another part of the reservoir. A water cycling scenario, with the injectors on the up-dip of the formation and producers on the down-dip, that starts at the same time as the carbon dioxide injection and continues 30 years after the end of carbon dioxide injection could reduce the plume size by 18%.
