Filed:

Jul 2, 2021

Appl. No.:

17/366183

Inventors:

- Houston TX, US
Peter Reid Maher - Lafayette LA, US

Assignee:

Halliburton Energy Services, Inc. - Houston TX

International Classification:

E21B 37/10
E21B 37/08
E21B 31/06

Abstract:

A variety of systems and methods are disclosed for cleaning a wellbore ahead of a well tool. The well tool is deployed on a tubular conveyance to a depth into a well. An interior surface of the well is wiped ahead of the well tool to dislodge debris from the interior surface of the well as the tubular conveyance advances downhole. The debris is filtered ahead of the well tool as the tubular conveyance advances downhole to keep the filtered debris away from the well tool. The well tool may then be used to perform a tool function when the tubular conveyance has reached the depth, without being affected by the filtered debris.

E21B 27/00

Abstract:

This disclosure provides a downhole debris removal apparatus, a method for assembling a downhole debris removal apparatus, and a well system including the same. The downhole debris removal apparatus, in one aspect, includes a crossover sub, the crossover sub having a first sub end with one of a sub pin thread or sub box thread, a second sub end with the other of the sub box thread or sub pin thread, and a fluid passageway extending from the first sub end to the second sub end. The downhole debris removal apparatus, according to this aspect, further includes a debris removal tube having a first tube end and a second tube end, the first tube end removably engaged with the crossover sub between the first sub end and the second end.

Alan Pace - Inverbervie, GB
Gavin Munro - Allen TX, US

International Classification:

E21B 37/02

Abstract:

A downhole tool for cleaning a wellbore includes a tool body having a passage therein. A liquid is to flow through the passage of the tool body and have an intermittent flow pattern. An inner sleeve positioned within the tool body includes a recess having a recess pattern. In response to the intermittent flow pattern of the flow of fluid, a shift pin positioned in the recess of the inner sleeve is to traverse through the recess pattern. The downhole tool includes at least one scraper blade. The scraper blade is movable between a retracted position and a radially expanded position. In response to the shift pin traversing the recess pattern of the recess, the scraper blade can be expanded radially outward toward a wall of the wellbore from the retracted position to the expanded position and/or retracted inward away from the wall of the wellbore from the expanded position to the retracted position.

International Classification:

E21B 37/08
E21B 23/02
E21B 33/129

Abstract:

A system and method for deployment of an isolation seal assembly wherein an isolation seal assembly is releasably attached to a reverse circulation debris removal tool. The system includes a debris removal tool having a head with an elongated snorkel extending from the head; and an isolation seal assembly attached to the head with a shear device so that the snorkel protrudes past the end of the isolation seal assembly. The isolation seal assembly further includes a tubular with a latch adjacent a first end, an external seal below the latch, and openings formed along tubular between latch and the seal. The debris removal tool is used to engage the isolation seal assembly with a lower completion assembly. The openings in the isolation seal assembly permit the debris removal tool to continue to function after the isolation seal assembly is engaged with the lower completion assembly.
