Pore Scale Observations of Trapped CO2 in Mixed-Wet Carbonate Rock: Applications to Storage in Oil Field

We investigated the physical basis of this weakened trapping using pore scale observations of supercritical CO2 in mixed-wet carbonates. The wetting alteration induced by oil provided CO2-wet surfaces that served as conduits to flow. In situ measurements of contact angles showed that CO2 varied from nonwetting to wetting throughout the pore space, with contact angles ranging 25° <θ< 127°; in contrast, an inert gas, N2, was nonwetting with a smaller range of contact angle 24° <θ< 68 °. Observations of trapped ganglia morphology showed that this wettability allowed CO2 to create large, connected, ganglia by inhabiting small pores in mixed-wet rocks. The connected ganglia persisted after three pore volumes of brine injection, facilitating the desaturation that leads to decreased trapping relative to water-wet systems.

Statement

All core-flooding experiments were performed at 10 MPa pore pressure. Observations were made with either CO2 and water or N2 and water as the two fluid phases. The CO2 experiments were performed at a temperature of 50 °C, while N2 experiments were performed at 25 °C. Observations were made of the ganglion distribution of N2brine or CO2-brine systems after an initial supercritical (sc)CO2 or N2 flooding stage, partially saturating the core with the nonaqueous phase, and again after waterflooding, where the remaining gas ganglia were imaged.
