Midfields State #1 WBD.xlsx

This is a Well Bore Diagram (WBD) for Midfields State #1, an oil and gas well located in Yuma County, Colorado, operated under API No. 125-05051 in the Beecher Island Field. The document outlines the well construction specifications, including multiple casing strings set at progressively deeper intervals: a 16-inch casing at 120 feet, a 12.5-inch casing at 1,002 feet, a 10-inch casing at 1,582 feet, and an 8.5-inch casing at 2,530 feet, with a total depth of 3,650 feet. The well includes a 16-inch PVC pipe with a 16-foot section inside the surface casing with a PVC cap. Cement plugs are proposed at 1,000 feet (50 sacks), 1,400 feet (50 sacks), and 1,500 feet (50 sacks), with additional cement placed at the surface and at various top-of-cement (TOC) locations throughout the wellbore. The surface location features a 100-sack cement placement at a 4-foot depth below ground level with a weld plate and no marker.

The diagram indicates both current and proposed configurations for the well construction, with cement volumes and plug placements noted throughout the wellbore. Top-of-cement locations for several casing strings are marked as unknown, suggesting ongoing evaluation or remedial work may be necessary. The specifications provided represent standard oil and gas well abandonment or remedial cementing procedures consistent with Colorado Department of Natural Resources regulations for well integrity and environmental protection.
