Buoyancy Technology Used Effectively in Casing Running Operations: Case History of Record Length Two-Stage Production Casing String

摘要

Operators today are tasked with locating ever more commercial reserves and producing those reserves with attention to lowering exploration and development costs. In addition to basic financial pressures, operators also face the need to reduce the environmental impact of well construction and production operations. Extended reach drilling technology allows operators to reach recoverable reserves that were unreachable in the past. Specifically, extended reach drilling from a multipad well site allows significant portions of the well construction costs to be spread over multiple wells, rather than being carried by an individual wellbore. Also, the ability to drill multiple wells from a single pad helps reduce the environmental impact of the drilling operation.
