International Classification:

E21B033/127
E21B023/00

US Classification:

166387, 166187, 166206, 166382, 277333

Abstract:

The present disclosure addressed apparatus and methods for forming an annular isolator in a borehole after installation of production tubing. Annular seal means are carried in or on production tubing as it is run into a borehole. In conjunction with expansion of the tubing, the seal is deployed to form an annular isolator. An inflatable element carried on the tubing may be inflated with a fluid carried in the tubing and forced into the inflatable element during expansion of the tubing. Reactive chemicals may be carried in the tubing and injected into the annulus to react with each other and ambient fluids to increase in volume and harden into an annular seal. An elastomeric sleeve, ring or band carried on the tubing may be expanded into contact with a borehole wall and may have its radial dimension increased in conjunction with tubing expansion to form an annular isolator.

Assignee:

Halliburton Energy Services, Inc. - Houston TX

International Classification:

E21B 10/22

US Classification:

175371, 175372

Abstract:

A drill bit () for drilling a wellbore that traverses subterranean formations includes a drill bit body () having a plurality of journal pins (), each having a bearing surface (), and a rotary cutter () rotatably mounted on each journal pin (), each rotary cutter () including a bearing surface (). A pressure-compensated reservoir () is in fluid communication with the bearing surfaces () and has a lubricant therein. A seal element () is positioned between each journal pin () and rotary cutter () and retains the lubricant in the bearing surfaces (). The seal element () is formed from a nanocomposite material including a polymer host material and a plurality of nanostructures.
