26th July 2022 for Immediate Release<\/strong><\/p>\n

SALT LAKE CITY, UTAH<\/p>\n

Cementation Americas (Cementation) a le plaisir d’annoncer l’ach\u00e8vement de l’\u00e9l\u00e9vation du puits #5 de Solvay Chemicals \u00e0 Green River, Wyoming.<\/p>\n

Project requirements were to complete a 22 ft. diameter shaft, complete with concrete liner, from surface to a depth of 1,506 ft. Concrete liner thickness increased as the depth of the shaft increased, so the initial concept was to complete a pilot slash raise with a raise bore drill and then slash from the top down to achieve the differing diameters to accommodate concrete liner thickness.<\/p>\n

Cementation Au lieu de cela, nous avons propos\u00e9 une solution de puits for\u00e9 sur toute la surface avec des diam\u00e8tres variables pour chaque section. We worked closely with Sandvik to design, engineer and manufacture a reaming head that could be diminished in diameter rather than manufacturing different diameters of outside wings. Final design allowed for five diameter options; maximum of 26.67 ft., down to 24.48 ft, in increments of 6.6 inches. The 26.67 ft. diameter reamer consisted of 12 individual sections, 46 cutters and weighed 136,000 lbs.<\/p>\n

Apr\u00e8s l’ach\u00e8vement de l’excavation et du rev\u00eatement du collier de 68 pieds de profondeur, la foreuse \u00e0 \u00e9l\u00e9vation Strata 950 de Cementationa \u00e9t\u00e9 install\u00e9e au-dessus du collier et un trou pilote de 16 pouces de diam\u00e8tre a \u00e9t\u00e9 for\u00e9 \u00e0 l’aide du syst\u00e8me de forage vertical rotatif (RVDS) de Micon. When the completed pilot hole was surveyed, the total deviation from vertical was found to be less than 4 inches over entire length of pilot hole.<\/p>\n

Based on the pilot hole survey it was determined that the first leg of the shaft would be reamed to 26.13 ft. diameter for 588 ft. of shaft, followed by 25.02 ft. diameter for the next 285 ft. of shaft and 24.47 ft. diameter for the final 535 ft. of shaft to surface.<\/p>\n

L’al\u00e9sage du puits a \u00e9t\u00e9 achev\u00e9 le 24 avril et les \u00e9quipes du puits Cementation sont en train d’achever le rev\u00eatement du puits. This raise was one of the largest ever pulled in the America\u2019s and was completed without incident. Its<\/p>\n

success was the result of a collaborative effort by all parties involved by providing the best technical solution for the Solvay Chemicals #5 Shaft.<\/p>\n\n\t\t
