Oilfield Chemistry Rock-Fluid Interaction Lab

The work in the Oilfield Chemistry Rock-Fluid Interaction Lab is focused towards characterizing interactions of injection/stimulation fluids such as brines and surfactants with reservoir rock and oil that directly affect well performance and oil recovery. The objective of such studies is to formulate affordable injection fluids that ensure high performance while favorably altering rock properties for secondary and tertiary modes of recovery.

Research Capabilities:

  • Contact angle, IFT, and zeta potential measurements at reservoir temperature.
  • Micro and nano-scale investigation of unconventional rock samples using CT scan technology and image processing techniques.
  • Spontaneous imbibition and core flooding experiments in controlled conditions in conjunction with CT scan technology.

Research Activities:

  • Investigating the effect of various surfactants on altering the wettability and interfacial tension of ULR core.
  • Conducting zeta potential measurements to evaluate further wettability alteration and stability of surfactant solution films on the shale rock surface.
  • Conducting spontaneous imbibition experiments with tested surfactants to measure oil expulsion volumes and hence, recovery as a function of time.
  • Implementing forced imbibition using surfactant solutions to recover additional oil and test the penetration of various surfactants.
