This document is a technical well completion schematic and history for the Watkins #1 "A" oil and gas well located in Baca County, Colorado, involving Wallace Oil and Gas, Inc. in relation to a bond claim (API No. 009-05147). The well is situated in the SENW section of Township 32S, Range 41W. The document outlines the well's construction specifications, including surface casing cemented at 4 feet below ground level with 15 sacks of cement, intermediate casing cemented at 1470 feet in an assumed 12-1/4" hole with 40 sacks of cement, and production casing set at 3267 feet in an assumed 6-3/4" hole. The well reaches a total depth of 3350 feet and includes multiple cement jobs across various geological formations including Stone Corral, Neva, Topeka, and Lansing intervals.

The well completion details specify multiple casing strings and cement quantities designed to ensure proper well integrity across different depths and formations. Perforations are noted at 3156 feet to 3139 feet for production purposes, with the final cement job calculated at 2750 feet using 100 sacks with assumed specifications of 1.18 cubic feet per sack and a 1.5 hole volume factor. The document indicates this is a historical well record associated with a bond claim, providing technical specifications necessary for well abandonment, remediation, or regulatory compliance purposes in Colorado's oil and gas operations.
