“…1B;Fassett and Hinds, 1971;Fassett , 2009). The Kirtland For-mation is divided into upper and lower shale (i.e., mudstone rich) members and a middle sandstone-rich member, the Farmington Sandstone (Bauer, 1917;Fassett and Hinds, 1971;Stone et al, 1983;Molenaar and Baird, 1992). Throughout most of the basin the Kirtland Formation conformably overlies the coal-bearing Fruitland Formation (Fassett and Hinds, 1971), which contains the world's most prolifi c coalbed methane play (Ayers, 2003).…”

Pore networks in continental and marine mudstones: Characteristics and controls on sealing behavior

Mudstone pore networks are strong modifi ers of sedimentary basin fl uid dynamics and have a critical role in the distribution of hydrocarbons and containment of injected fl uids. Using core samples from continental and marine mudstones, we investigate properties of pore types and networks from a variety of geologic environments, together with estimates of capillary breakthrough pressures by mercury intrusion porosimetry. Analysis and interpretation of quantitative and qualitative three-dimensional (3D) observations, obtained by dual focused ion beamscanning electron microscopy, suggest seven dominant mudstone pore types distinguished by geometry and connectivity. A dominant planar pore type occurs in all investigated mudstones and generally has high coordination numbers (i.e., number of neighboring connected pores). Connected networks of pores of this type contribute to high mercury capillary pressures due to small pore throats at the junctions of connected pores and likely control most matrix transport in these mudstones . Other pore types are related to authigenic (e.g., replacement or pore-lining precipitation) clay minerals and pyrite nodules; pores in clay packets adjacent to larger, more competent clastic grains; pores in organic phases; and stylolitic and microfracture-related pores. Pores within regions of authigenic clay minerals often form small isolated networks (<3 μm). Pores in stringers of organic phases occur as tubular pores or slit-and/or sheet-like pores. These form short, connected lengths in 3D reconstructions, but appear to form networks no larger than a few microns in size. Sealing effi ciency of the studied mudstones increases with greater distal depositional environments and greater maximum depth of burial.

“…They are based on published and unpublished information as follows, from southwest to northeast. The data for east-central Arizona and the southern part of the Zuni basin were obtained mostly from Wolfe (1989); data for the Zuni basin and the southern flank of the San Juan basin were derived from the work of Hook and others (1983) and Molenaar (1983); data for the subsurface of the San Juan basin were supplied by Molenaar and Baird (1992); and data for the panhandle of Oklahoma and northeasternmost New Mexico area were obtained partly from a publication by Holbrook (1992). Stratigraphic nomenclature proposed for the area of Pagosa Springs by Leckie and others (1997) The distance along Transect D-D'' is about 615 mi (990 km).…”

“…The basal Mesaverde is gradational with the underlying marine Mancos Shale, whereas the upper contact intertongues with the overlying marine Lewis Shale ( fig. 11) (Molenaar and Baird, 1992). Potential storage units within the Mesaverde Group include, in ascending stratigraphic order, the Point Lookout Sandstone, sandstones of the Menefee Formation, and the Cliff House Sandstone.…”

“…IHS Energy Group (2010) data indicate the most likely range of the total thickness of the SAU is from 1,800 to 2,200 ft, with 2,000 ft being the regional mean thickness. Data of Reneau and Harris (1957), Arnold (1974), Molenaar and Baird (1992), and Whitehead (1993) were employed for net-to-gross ratio determination of the thickness of potential storage formation intervals within the SAU. The resulting 0.08 net-to-gross ratio proportion was applied to the gross thickness values, yielding minimum, maximum, and most likely net-porous thicknesses of 120, 200, and 160 ft, respectively.…”

The U.S. Geological Survey has completed an assessment of the potential geologic carbon dioxide storage resources in the onshore areas of the United States. To provide geological context and input data sources for the resources numbers, framework documents are being prepared for all areas that were investigated as part of the national assessment. This report is the geologic framework document for the Uinta and Piceance, San Juan, Paradox, Raton, Eastern Great, and Black Mesa Basins, and subbasins therein of Arizona, Colorado, Idaho, Nevada, New Mexico, and Utah. In addition to a summary of the geology and petroleum resources of studied basins, the individual storage assessment units (SAUs) within the basins are described and explanations for their selection are presented. Although appendixes in the national assessment publications include the input values used to calculate the available storage resource, this framework document provides only the context and source of the input values selected by the assessment geologists. Spatial-data files of the boundaries for the SAUs, and the well-penetration density of known well bores that penetrate the SAU seal, are available for download with the release of this report.
