THIN-WALLED LINER EQUIPMENT CUTS COSTS ON WELL DEEPENING PROJECT
Thin-walled, slim hole liner equipment can save $3-4 million per well in deep reentry applications by allowing existing wells to be deepened or sidetracked rather than drilling new wells from surface. The design makes it possible to reenter existing wells, successfully isolate depleted zones, and deepen the well into virgin-pressured reservoirs. The design includes thin-walled, close-tolerance liner hangers, liner top packers, tieback seal assemblies, and liner setting sleeves that provide reasonable burst and collapse resistance while maintaining an inside diameter to facilitate drilling a deep, deviated 4 and 3/4-inch hole with a tapered 2 and 7/8 inch X 3 and 1/2 inch drillstring.
