Blank Casing: TABLE 4 WELL CONSTRUCTION INFORMATION Well Drilling Method: Borehole Diameter: Annulus Size: I am uncertain if a pitless adaptor will be installed on the well Well Screen: Well Seals: Legend Well - Grout Seal Certification Description of Well Sealing Process: On August 4, 2022, Lang Equipment (Lang) sealed the 14-inch diameter surface casing for the Legend Well from a depth of 114 feet up to ground surface with neat cement grout. Each neat cement grout batch was prepared in a 500-gallon mixer and grout pump and installed in the borehole through a 2.3-inch diameter (BQ) tremie pipe. Each neat cement grout batch was prepared by mixing a supersack (approximately 2500 pounds) of Type I/II Portland cement with approximately 145 gallons (gals) of water. The first (hot) batch was prepared by also mixing 50 pounds (lbs) of calcium chloride into the grout batch. A total of 17 batches (547 cubic feet) were mixed and installed in the borehole and each batch was installed immediately after mixing and measuring the grout density. Grout Material:Neat cement grout Grout Volume:The theoretical volume of the annular space between the 14-inch diameter surface casing and the borehole wall from ground surface to a depth of 114 feet is 103 cubic feet. Lang installed approximately 547 cubic feet of neat cement grout around the surface casing. The discrepancy between the theoretical volume and the installed volume is due to large washouts in the borehole and grout flowing out into the very permeable formation. Grout Density:The grout density was measured to be between 16.5 and 15.2 pounds per gallon (lbs/gal) prior to installation in the borehole. The average density was 15.4 lbs/gal. Method of Placement: Tremie pipe and grout pump. Depth from Surface: The certified cement grout well seal extends from ground surface to a depth of 114 feet. Did Grout Come to the Surface? Yes grout came to the surface. Length of Tremie Pipe: The bottom of the tremie pipe was set to a depth of approximately 110 feet for the first (hot) batch of neat cement grout. The tremie was then set to a depth of 110 feet and 14 batches were installed. The tremie was then set to a depth of 60 feet and 2 more batches were installed. The tremie was then removed from the borehole after grout returns at the surface. Issues Observed During Well Sealing: No issues were observed during the installation of the neat cement grout seal for the Legend Well.
