About this file
This is a cost estimation worksheet for well plugging and abandonment activities across multiple sites. The document contains two primary tables detailing deep monitoring wells and skewed reservoir wells, along with associated costs for materials and services.
Table 1 lists 17 deep monitoring wells at various sites including Kingsbury, Napier, Durham Ranch, Remington, Sasquatch, Carr Draw, Timar Stockwell, Coal Gulch, Petrified Tree, and Ford Ranch. For each well, the worksheet tracks production casing specifications (setting depth, outer diameter, weight, inner diameter), cement requirements (total length and number of sacks with 10% excess), bentonite usage, casing volume calculations, and cost components including cement ($-/sack), bentonite ($-/bag), CIBP (Cement In-Between Plugs), mobilization/demobilization, rig time, and reclamation costs. Production casing depths range from 100 feet to 1,970 feet. Table 2 documents 20 skewed reservoir wells (SK1 through SK18) with total depths ranging from 22.4 to 124.34 feet, calculating bentonite requirements and associated costs at $17 per bag. Both tables include line items for mobilization/demobilization, steel casing removal, and reclamation activities. All cost columns currently display "$-" placeholders, indicating the worksheet is configured for cost data entry. Summary rows at the bottom aggregate costs for each well category and provide a total project cost line.
