MetalSkin® Monobore Open-Hole Liner System
Weatherford’s MetalSkin® monobore open-hole liner system reduces installation risks, minimizes well construction costs, and mitigates drilling hazards. The system eliminates the slimming of a well profile during well construction to improve well productivity and reservoir recovery. An oversized shoe is run into the hole with the previous string of casing. After it is installed at the bottom of the previous casing string, the oversized shoe can be drilled out with conventional bottomhole drilling assemblies.
Once the next hole section is drilled, the expandable liner extension is run to total depth of the well and expanded back into the oversized shoe. This technique provides an expanded string of casing with the same drift as the previous casing string; therefore, a string of casing is gained with no loss of hole size.
The design provides a full bore in the overlap between the monobore open-hole liner system and the parent casing string, reducing operational risk by eliminating the need to over-expand the shoe track to receive the expanding MetalSkin system.
Weatherford’s full suite of new-generation solid expandable systems significantly reduces installation risks. In addition to the monobore open-hole liner system, this offering includes the MetalSkin open-hole liner, cased-hole liner, and monobore open-hole clad systems.
