Title: Surface and Subsurface Characterization of a Carbon Sequestration Pilot Site: San Juan Basin, NM

Abstract

Successful sequestration of CO2 requires that the majority of injected CO2 remain underground for hundreds to thousands of years. Evaluation of site integrity is important in the design and implementation stages of the sequestration effort. This study presents some of the background evaluation undertaken of a Fruitland coal pilot sequestration site located in the San Juan basin. The study includes comparison of fracture traces measured in the field and in high resolution QuickBird satellite imagery, along with multi-frequency terrain conductivity surveys and subsurface maps of the surrounding area. Prominent fracture systems are exposed along the edges of mesas formed in the nearly flat-lying Eocene age San Jose Formation. Fracture trend varies considerably, however, rose diagrams reveal two prominent fracture sets: one trending ~N30E and the other ~N45W. Analysis of the QuickBird image reveals similar variability along with two prominent sets: one trending N35E and another smaller set trending N50W. Previous studies in the area suggest that the face cleat orientation and direction of preferential flow during CO2 injection will follow this NE trend. The site lies in the "High Rate Fairway" near a structural low in the Fruitland Formation. Subsurface maps will help determine whether smaller scale folds and faultsmore » similar to those observed to the northwest in the Cedar Hill area exist. If present, they may exert additional control on CO2 flow patterns and serve as potential avenues for CO2 escape. The study will help National Energy Technology Laboratory scientists position tracer and soil monitors at the site.« less

  • Three wedges of transgressive marine Mancos Shale, deposited off-shore, intertongue with four Dakota Sandstone units, largely shoreface deposits. Contacts between shoreface and offshore lithologies trend approximately north-south, with nonmarine Dakota main body sandstones to the west. Submarine bar sandstones trending northwest-southeast are locally developed near the shoreface-offshore transition. This succession was deposited during approximately 4 m.y. of the transgressive phase of the Greenhorn cyclothem. Each Dakota-Mancos sandstone-shale pair may represent (1) a fourth-order eustatic cycle or (2) regional tectonic and local sedimentologic overprints of two third-order Vail cycles. Detailed analyses of trace elements within shales and primary sedimentary structures andmore » trace fossils of sandstones, combined with geophysical logs and regional paleontologic control, were invaluable in this first, basin-wide, surface and subsurface paleoenvironmental study of these complex strata. Dakota main body and basal fluvial sandstones were deposited by easterly flowing, meandering stream system. Overlying sets of extensively burrowed shoreface sandstones were deposited under prevailing southerly paleocurrents. The uppermost Dakota tongue (Twowells Sandstone) illustrates a dominant, but complex, regressive character and a seaward pinch-out, as well as a thin, upper transgressive phase in nearshore locations. Significant petroleum accumulations are contained in this sandstone.« less

  • Near-surface monitoring and subsurface characterization activities were undertaken in collaboration with the Southwest Regional Carbon Sequestration Partnership on their San Juan Basin coal-bed methane pilot test site near Navajo City, New Mexico. Nearly 18,407 short tons (1.670 × 107 kg) of CO{sub 2} were injected into 3 seams of the Fruitland coal between July 2008 and April 2009. Between September 18 and October 30, 2008, two additions of approximately 20 L each of perfluorocarbon (PFC) tracers were mixed with the CO{sub 2} at the injection wellhead. PFC tracers in soil-gas and in the atmosphere were monitored over a period ofmore » 2 years using a rectangular array of permanent installations. Additional monitors were placed near existing well bores and at other locations of potential leakage identified during the pre-injection site survey. Monitoring was conducted using sorbent containing tubes to collect any released PFC tracer from soil-gas or the atmosphere. Near-surface monitoring activities also included CO{sub 2} surface flux and carbon isotopes, soil-gas hydrocarbon levels, and electrical conductivity in the soil. The value of the PFC tracers was demonstrated when a significant leakage event was detected near an offset production well. Subsurface characterization activities, including 3D seismic interpretation and attribute analysis, were conducted to evaluate reservoir integrity and the potential that leakage of injected CO{sub 2} might occur. Leakage from the injection reservoir was not detected. PFC tracers made breakthroughs at 2 of 3 offset wells which were not otherwise directly observable in produced gases containing 20–30% CO{sub 2}. These results have aided reservoir geophysical and simulation investigations to track the underground movement of CO{sub 2}. 3D seismic analysis provided a possible interpretation for the order of appearance of tracers at production wells.« less
