BRIDGE PLUG<br />

NOT TO SCALE<br />

In September 1986, Cabin Baby-I was recompleted<br />

as a Culebra observation well. The PIP at the base <strong>of</strong><br />

the Castile was replaced by a retrievable bridge plug,<br />

and another retrievable bridge plug was set in the<br />

well casing from about 585.4 to 588.4 ft deep. The<br />

casing was perforated between the depths <strong>of</strong> 503<br />

and 529 ft, which coincides with the Culebra interval<br />

identified from a gamma-ray log run immediately<br />

before perforation (all Cabin Baby-I stratigraphic<br />

depths above the Salado reported in <strong>Beauheim</strong> et al.<br />

(1983) are incorrect). Following the recompletion,<br />

the well was developed between September 23 and<br />

October 3, 1986 by repeatedly pumping most <strong>of</strong> the<br />

water from the well and allowing the water level to<br />

recover. Additional recompletion and welldevelopment<br />

information is contained in Stensrud et<br />

al. (<strong>1987</strong>). To facilitate the <strong>1987</strong> slug testing, a PIP<br />

DOE-1 was drilled in July 1982 to investigate a<br />

structural anomaly in the Castile Formation inferred<br />

from seismic-reflection surveys, The well was drilled<br />

at a 14.75-inch diameter to a depth <strong>of</strong> 1122.5 ft, and<br />

10.75-inch casing was set and cemented from about<br />

11 18 ft to the surface. A 7.875-inch hole was then<br />

drilled to a total depth <strong>of</strong> about 4057 fi (Freeland,<br />

1982). In March 1983, a retrievable bridge plug was<br />

set in the casing at a depth <strong>of</strong> about 858 ft, and an<br />

interval encompassing the Culebra from 820 to 843 ft<br />

deep was shot-perforated using 4 shotsfft<br />

(HydroGeoChem, 1985). The well was developed<br />
