WBD Newman 1-7.pdf

This is a well documentation file related to an oil and gas well operation in Baca County, Colorado, specifically detailing the wellbore schematic and construction history for the Newman #1-7 well (API No. 009-05175) operated by Wallace Oil and Gas, Inc. The document presents both current and proposed well configurations, including detailed specifications for casing, cementing operations, and perforations at multiple geological formations. Key construction elements include 15 sacks of cement at the surface with a 4-foot below-ground-level cut and weld ID plate; 630 sacks of cement assumed to surface; a 7-inch, 23-pound J-55 casing set at 1,266 feet 7 inches in a 12-1/4-inch hole with 40 sacks of cement; and a 4-1/2-inch, 9.5-pound J-55 casing set at 3,250 feet total depth in a 6-1/4-inch hole. The well intersects multiple stratigraphic formations including Stone Corral (top at 1,478 feet), Neva (top at 2,612-2,618 feet), and Topeka (top at 2,980-2,987 feet), with perforations conducted at depths between 3,161 and 3,181 feet.

The document indicates this is associated with a bond claim by Wallace Oil and Gas, Inc., suggesting potential compliance or financial security matters related to well operations. Specific cementing calculations are documented with assumed volumes of 1.18 cubic feet per sack and 1.5-fold hole volume factors for top-of-cement calculations. The wellbore construction specifications reflect standard industry practices for onshore conventional oil and gas development in the Rocky Mountain region, with detailed attention to casing grades, weights, and cement volumes necessary for well integrity across multiple pay zones.
