Characterization of Natural Fractures in Mesaverde Core from the Multiwell Experiment SAND 88-1800.pdf
This report lists and characterizes 1900 natural fractures found in 4200 feet of 4-inch diameter Mesaverde core, much of it oriented, from the MWX site in the Piceance basin of northwestern Colorado. The different types of fractures are analyzed and the data synthesized to explain the fracture origins, the tectonic history recorded by the fractures, and the reservoir plumbing system that fractures create. A second dimension characterizing the spacing of these fractures from deviated core taken from a slant/horizontal hole at this site is described in Lorenz, J.C., and Hill, R.E., 1994, Subsurface fracture spacing: Comparison of inferences from slant/horizontal and vertical cores: SPE Formation Evaluation, v. 9, p. 66-72.

Teapot Dome and Spraberry Formation:
Papers published in the American Association of Petroleum Geologists Bulletin on fractures at Teapot Dome (Wyoming) and in the Spraberry Formation (Midland basin, Texas) are provided as locked PDFs courtesy of AAPG. Additional publications are available through the AAPG at www.aapg.org.

The Teapot Dome Fracture Project data are utilized as the basic fracture database in fracture modeling classes.

Coring-Induced Fractures:
Recognition and Use of Induced Fractures, and Other Features in Core Produced by the Coring Process SAND 95-1482C.pdf
This report lists and describes several types of induced fractures and artifacts,created by the coring/drilling process, providing a basis for separating induced from natural fractures in core. The described structures include petal, centerline, scribe-knife, torque, and saddle fractures, as well as natural fractures in horizontal core modified by the coring process.

Department of Energy Reports:
Many of our publications with the Department of Energy are available through the DOE's Information Bridge website at www.osti.gov. This site provides free public access to all of the DOE's Scientific and Technical publications, search by author, title or area of interest.
