AB: A pilot sequestration test has recently been performed in a depleted oil reservoir near Hobbs, NM. About 2,100 tons of CO$_{2}$ were injected into the West Pearl Queen reservoir. The site has been characterized geologically by information from well logs. Additionally, as potential CO$_{2}$ leakage pathways are a concern, a lineament analysis and ground-penetration radar (GPR) study have been performed to help understand better the near-surface geology. As part of the MM&V study, three perfluorocarbon tracers (PFTs) were injected for three twelve-hour periods with the carbon dioxide. Capillary absorption tube samplers (CATS), used to detect the presence of PFTs in small quantities, were located near the surface in a circular pattern stretching about 300m from the injection well. The CATS were sampled at different times to determine if any changes would be seen as injection progressed. From the geologic data that has been collected, a geomechanical model and a flow model have been developed for the site. The geomechanical model has been used to help predict the deformations caused in the reservoir and surrounding rock and identify potential fracture zones. The flow of CO$_{2}$ and tracer has been modeled at the site to help identify potential leakage pathways. Near the surface, in the vadose zone, the fluids are modeled by diffusion in one model, and by a combination of advection and diffusion in another. A reservoir simulator has been used to model flow of the carbon dioxide in the reservoir and overburden strata. The presentation will contain lessons learned from this MM&V study.
