Thermal Recovery Studies

Combustion set up featuring heavy framework holding large metal tube nearly upright and attached to monitoring equipment

In-situ combustion (ISC): One-dimensional combustion tube set-up consists of combustion tube assembly, pressure, temperature and flow monitoring system, and a gas analyzer. The experimental results obtained from combustion tube experiments are used to calculate the most important design parameters (air requirements, pump selection, well configuration, etc.) to field-scale implementation of ISC. 

 

 

 

Steam flooding set-up featuring large metal tube in horizontal position attached to steam generator and monitoring equipment

Steam Flooding (SF): One-dimensional steam flooding experimental set-up consists of one-dimensional stainless steel tube, steam generator, pressure, temperature and flow monitoring system, and a gas chromatogram. The experimental results obtained from steam flooding experiments are used to calculate some important design parameters (SOR, Energy input, GHG emissions, etc.) for the field-scale application.

Steam Assisted Gravity Drainage (SAGD): Two-dimensional SAGD consists of two stainless steel concentric cylinders, steam generator, pressure, temperature and flow monitoring system, and a gas chromatogram. The experimental results obtained from SAGD experiments are used to calculate some important design parameters (steam chamber development SOR, Energy input, GHG emissions, etc.) for the field-scale application.

 

 

 

Electromagnetic and Electrical Heating: One-dimensional experimental set-ups consist of one-dimentional core holders, pressure, temperature and flow monitoring system, and a gas chromatogram.

Heavy metal box approximately one foot tall two feet wide and three feet long bolted on end seams and enforced with three metal tubing clamps around box and one down length shown on table with monitoring equipment attached in center at one end

Three-dimensional experimental set-up for thermal recovery application: This set-up is designed to simulate the quarter of a reservoir for any thermal recovery application in a three-dimensional setting.

Zeta Potential Measurement: Zeta Potential measures the potential difference between the surface charge of colloids and the suspending liquid. The electrostatic forces acting on the reservoir rocks and fluids are observed to determine wettability change, asphaltene precipitation mechanism, and emulsion formation mechanism.
