Title: Basic data report for borehole Cabin Baby-1 deepening and hydrologic testing. Waste Isolation Pilot Plant (WIPP) project, southeastern New Mexico

Technical Report ·
OSTI ID:6319208

Borehole Cabin Baby-1 was originally drilled to a depth of 4159.0 feet below kelly bushing (8.0 feet above ground surface) in 1974 and 1975 as a ''wildcat'' hydrocarbon exploratory well. Control of the borehole was given to the US Department of Energy (DOE) after it was found to be a ''dry hole''. Cabin Baby-1 was reentered, deepened, and hydrologically tested in August and September 1983. The well is located in Section 5, T23S, R31E, just outside the limit of WIPP Zone III, approximately 2.5 miles south of the WIPP exploratory shaft. The deepening and testing of Cabin Baby-1 was undertaken for several reasons: to provide data on the hydrologic properties, including hydrostatic head potential of selected permeable zones in the Bell Canyon Formation; to provide representative fluid samples from selected permeable zones in the Bell Canyon Formation for determination of fluid composition and density; and to define further the stratigraphy of the upper Bell Canyon Formation at the Cabin Baby-1 location. The borehole was deepened from the previous total depth to a new depth of 4298.6 feet below kelly bushing by continuous coring. Field operations related to deepening and logging of the borehole began August 12, 1983 and were completed August 30, 1983. Hydrologic testing activities began August 30, 1983 and were completed September 29, 1983. Drill-stem tests were conducted in four zones in the Bell Canyon Formation, and one test of the Salado Formation was performed. Fluid samples were collected from the Hays and Olds sandstones of the Bell Canyon Formation.
