From 2006 through 2014 the CGS participated in the Southwest Regional Partnership (SWP) on Carbon Sequestration project whose primary goal was to determine an optimum strategy for minimizing greenhouse gas levels in the southwestern United States. The SWP was led by the New Mexico Institute of Mining and Technology and comprised a large, diverse group of expert organizations and individuals specializing in carbon sequestration science and engineering, as well as public policy and outreach. The project is sponsored by the Department of Energy’s National Energy Technology Laboratory.

This is the final report from Phase II of the SWP project covering the period 2006-2009. Digital PDF download. ENE-2010-02D

From the Executive Summary:

Within the SWP, three demonstrations of geologic CO2 sequestration are being performed – one in an oilfield (the SACROC Unit in the Permian basin of west Texas), one in a deep, unmineable coalbed (the Pump Canyon site in the San Juan basin of northern New Mexico), and one in a deep, saline reservoir (underlying the Aneth oilfield in the Paradox basin of southeast Utah). The Pump Canyon CO2-enhanced coalbed methane (CO2/ECBM) sequestration demonstration project plans to demonstrate the effectiveness of CO2 sequestration in deep, unmineable coal seams via a small-scale geologic sequestration project. The site is located in San Juan County, northern New Mexico, just within the limits of the high-permeability fairway of prolific coalbed methane production. The study area for the SWP project consists of 31 coalbed methane production wells located in a nine section area.

CO2 was injected continuously for a year and different monitoring, verification and accounting (MVA) techniques were implemented to track the CO2 movement inside and outside the reservoir. A total of 256 MMscf of CO2 (or 14,885 tons) were injected over a 12-month period (July 30st, 2008 to August 12th, 2009); primarily due to highly permeable coal. However, as expected, the CO2 injectivity dramatically decreased over the injection period. This was mainly due to matrix swelling and permeability reduction, as a result of the CO2 being adsorbed onto the coal, while displacing methane, as well as increasing reservoir pressure. It was also determined that injection was predominately into the basal coal, reducing injectivity by 20%.
