WlPP site. The aggregate thickness of the Fortyniner varies between 55 (DOE-1) and 76 ft (P-18). All of the Rustler members are believed to be saturated. The Culebra dolomite is the most transmissive member, and is considered to be the most important potential groundwater-transport pathway for radionuclides which may escape from the WlPP facility to reach the accessible environment. Hence, the vast majority of hydrologic tests performed at the WlPP site have examined the hydraulic properties of the Culebra. The Magenta dolomite is generally considered to be the secondmost transmissive Rustler member, and has been tested at numerous locations by the US. Geological Survey (Mercer, 1983). Magenta hydraulic heads are generally higher than those of the Culebra. The other members of the Rustler are believed to have low permeabilities; few hydraulic tests have beenperformed on them and little is known about their hydraulic properties. The Dewey Lake Red Beds consist of siltstone with claystone and sandstone interbeds. Numerous bedding-plane breaks and fractures at various angles to the bedding are filled with secondary selenite. A well H-14, the Dewey Lake Red Beds are 320 ft thick, lying from 40 to 360 ft below ground surface. Continuous zones of saturation have not been observed within the Dewey Lake where it overlies the underground WlPP facility, although some minor, possibly perched, moist zones have been noted (Mercer, 1983). The Dewey Lake does provide small quantities of water to wells south and southwest of the WlPP site (Mercer, 1983). Cenozoic alluvium forms aquifers in much of the Delaware Basin, particularly in northern Texas. The alluvium consists of fluvial deposits, caliche, gypsite, conglomerates, aeolian sands, terrace deposits, and playa deposits (Richey et al., 1985). The alluvium is thickest in depressions caused by dissolution of the Salado. In southeastern Eddy County, the alluvium occurs past the erosional limit of the Dewey Lake Red Beds, and rests on an erosional/dissolution surface that moves progressively downsection from east to west from the Rustler to the Castile (Bachman, 1984). 20
3. TEST WELLS Most of the wells discussed in this report were drilled from 1974 to 1987 for a variety of purposes. Many of them have been recompleted one or more times since the original drilling. Some of the wells are, or were, open holes through the strata tested, while others are cased and perforated to the tested intervals. The following sections contain brief histories of the wells, along with descriptions of their configurations at the times of testing. Unless otherwise indicated, all depths listed below are referenced to ground surface. 3397.90 It 7-inch. 26 Ib/ft ~ WELL CASING 9.87Clnch REAMED BOREHOLE- 3199. m n / I I I MAGENTA DOLOMITE sas n - m 397.7 n- 34w 18 n 2 375-Inch TUBING TRANSDUCER 3.1 H-1 Well H-1 was drilled in May and June 1976 as the first hydrologic test hole for the Rustler Formation at the WlPP site. After drilling, selected coring, and openhole testing, the well was reamed to a diameter of 9.875 inches to a total depth of 856 ft (Mercer and Orr, 1979). Seven-inch casing was installed and cemented from 848 ft to the surface, and a cement plug was left in the casing at a depth of 831 ft. Three sections of the casing were subsequently perforated using jet shots: the Rustler/Salado contact zone between 803 and 827 ft; the interval between 675 and 703 ft, including the Culebra from 676 to 699 ft; and the interval between 562 and 590 ft, including the Magenta from 563 to 589 ft. Following testing in 1977, a retrievable bridge plug was set in the casing at about 790 ft, and a production-injection packer (PIP) was set on 2.375-inch tubing at about 651 ft. This configuration allowed monitoring of the Culebra water level through the 2.375-inch tubing, and monitoring of the Magenta water level in the annulus between the well casing and the tubing. The PIP was replaced with a similar PIP in July 1987 set from 645.0 to 649.4 ft on 2.375-inch tubing. The Culebra interval was developed by bailing on August 27, September 1, and September 15,1987 in preparation for slug testing (Stensrud et al., 1988). A smalldiameter minipacker was set in the tubing temporarily at about 600 ft for use in the slug testing. The configuration of H-1 at the time of the 1987 testing is shown in Figure 3-1. wen 1//1 CULEBRA DOLOMITE #@@e- TSOW- ALL DEPTHS BELOW GROUND SURFACE Figure 3-1. Well Configuration for H-1 Slug Tests 3.2 H-4~ NOT TO SCALE Well H-4c was originally drilled in April and May 1978 to serve as a Rustler-Salad0 contact monitoring well. A 7.875-inch hole was drilled and reamed to a depth of 609.5 ft, and 5.5-inch casing was cemented from that depth to the surface. A 4.75-inch hole was then cored to a total depth of 661 ft, about 35 ft into the Salado Formation (Mercer et al., 1981). In February 1981, a retrievable bridge plug was set in the casing at a depth of about 530 ft. The depth interval from 494 to 520 ft was then shot-perforated to provide access to the Culebra. Mercer et al. (1981) report the Culebra at H-4c as lying between 490 and 516 ft 21
