CO2 EOR Coreflood, Swelling and MMP Experiments

CO2 EOR Coreflood, Swelling and MMP Experiments

  Carbon dioxide (CO2) injection for enhanced oil recovery is a proven technology. It is also considered as one of the most promising methods for carbon sequestration in geologic formations. CO2 injections are normally operated at a pressure above the minimum miscibility pressure (MMP), which is affected by crude oil composition and reservoir conditions. TORP has completed several DOE funded project in CO2 miscible, near miscible and immiscible flooding application. The laboratory is well equipped to conduct phase behavior study relevant to gas injection and core flooding experiment with CO2 and other type of gas.

  In-house swelling test apparatus can measure the swelling factor of swollen oil mixture with the injection of carbon dioxide or other gas of interest and determine saturation pressure as well as gas solubility. The slim tube apparatus can measure the minimum miscible pressure (MMP) of carbon dioxide or other gas of interest with crude oil by conducting 4 to 6 pressure tests.

  • Slim tube : 40-foot glass bead packed column, permeability of 4.9 Darcy and porosity of 36.7%
  • Core dimension for displacement test: 1, 1.5, and 2 inch ID and maximum 12 inch in length
  • Temperature: 68-400 °F
  • Pressure: up to 5,000 psi
  • Gas type: Carbon dioxide, Nitrogen, methane, ethane, propane, and natural gas
