Lateral wells, Peabody Mine
NOVAFAST PRODUCT
Novafast supplied its 7-inch NovaBore™ GRE casing to Lucas Drilling for 12 lateral wells on the Peabody 2025 Campaign at Centurion North Mine, Queensland. Deployed to 420m TVD/745m MD, NovaBore™ effectively isolated unconsolidated coal seam roofs and kept steel over 3m from the mining horizon. Its slim design allowed drilling an 8.5-inch hole instead of 9-7/8-inch, significantly reducing drilling costs for Peabody and enabling a smaller surface casing.
The challenge
Isolate unconsolidated coal seam roofs and maintain a >3m steel-free zone from the mining horizon during 12 lateral well drillings at Peabody’s Centurion North Mine. Traditional methods meant larger, costlier drill holes.
The solution
Novafast’s 7-inch non-conductive NovaBore™ GRE casing. Its composite material inherently met the steel-free zone requirement and stabilised the coal seam. Critically, its slim, 7-inch BTC geometrical design allowed Lucas Drilling to use a smaller 8.5-inch drill hole.
Execution
NovaBore™ casing was successfully run to 420m TVD/745m MD across all wells, contributing to efficient well construction. Smaller 8.5-inch drill holes directly saved Peabody substantial drilling costs.
