Project Description: |
Co-injection of a mineral reactant slurry; either with the
CO2 or in separate; secondary injection wells; could provide a means to
enhance the natural reservoir seals by precipitation of mineral carbonates
along the periphery of the injection plume.
The proposed study evaluates the merit of several mineral slurry
co-injection strategies; by compilation of a current geochemical and
engineering literature review on saline aquifer injection; and conduct of a
limited number of proof-of-concept laboratory-scale pressure-leach
experiments. The resulting Final
Report will include the literature review; discussion of the merit of the
mineral slurry co-injection concept; and a path forward for any methodology
deemed worthy of further investigation. |

Project Background: |
: Geological sequestration of CO2; whether by
enhanced oil recovery (EOR); coal-bed methane (CBM) recovery; or saline
aquifer injection is a promising near-term sequestration methodology. While tremendous experience exists for EOR;
and CBM recovery has been demonstrated in several existing fields; saline
aquifer injection studies have only recently been initiated. Studies evaluating the availability of
saline aquifers suitable for CO2 injection show great potential; however; the
long-term fate of the CO2 injected into these ancient aqueous systems is
still uncertain. Migration of the CO2
beyond the natural reservoir seals could become problematic; thus the
identification of means to enhance the natural seals may have a significant
impact on the utilization of this sequestration methodology. Co-injection of a mineral reactant slurry;
either with the CO2 or in separate; secondary injection wells; could provide
a means to enhance the natural reservoir seals by precipitation of mineral
carbonates along the periphery of the injection plume. The proposed study evaluates the merit of
several mineral slurry co-injection strategies; by compilation of a current
geochemical and engineering literature review on saline aquifer injection;
and conduct of a limited number of proof-of-concept laboratory-scale pressure-leach
experiments. The resulting Final
Report will include the literature review; discussion of the merit of the
mineral slurry co-injection concept; and a path forward for any methodology
deemed worthy of further investigation. |
