Filed:

Dec 27, 2016

Appl. No.:

15/563445

Inventors:

- Houston TX, US
Gregory William GARRISON - Dallas TX, US

Assignee:

Halliburton Energy Services ,Inc. - Houston TX

International Classification:

E21B 34/06
E21B 33/12

Abstract:

A system for use in completing a wellbore includes a portion of a workstring extending into the wellbore such that a first annulus is created between the workstring and a portion of the wellbore. The portion of the workstring is inserted to a depth corresponding to a base, such as a sump packer that defines a lower boundary of the completion zone. The zone of deployment may be sealed uphole by a second packer included in the workstring. A service tool having an inner sleeve, an outer sleeve, and a rotating mandrel positioned therebetween is provided to deliver fluids and execute completion operations as facilitated by rotation of the mandrel. Rotation of the mandrel allows for control of multiple fluid flow paths, each of which may correspond to a completion process within the zone, without displacement of the service tool in an uphole or downhole direction.

Abstract:

A method and apparatus that includes an elongated base pipe having an external surface at least partially defining an external region and an internal surface at least partially defining an internal region; and a pressure maintenance device disposed in the base pipe and comprising: a flow path that extends between the internal region and the external region; and a valve having a gas charged chamber, the valve allowing the flow of a fluid from the internal region to the external region through the first flow path when a pressure differential between a pressure associated with the internal region and a pressure associated with the gas charged chamber is less than a maximum pressure threshold and when a pressure differential between the external region and the pressure associated with the gas charged chamber is greater than a minimum pressure threshold.

E21B 43/12

Abstract:

A method and apparatus that includes positioning a completion string that has an internal passageway and that has an external surface that at least partially defines an external region within a wellbore; isolating a zone of the external region from a wellbore hydrostatic pressure; measuring a pressure within the external region of the isolated zone; determining whether the pressure within the external region of the isolated zone is within a predetermined pressure range; and operating a valve that controls a flow of a fluid through a flow path from the internal region to the external region of the isolated zone when the pressure within the external region is outside of the predetermined pressure range.

International Classification:

E21B 34/10
E21B 33/12
E21B 47/06
E21B 34/14

Abstract:

An exemplary downhole system includes a completion string positioned within a wellbore and providing at least an upper seal bore and a downhole device that includes a sliding sleeve. A service tool is extendable within the completion string and includes a shifting tool assembly and provides a mandrel, a shifting tool coupled to the mandrel, and upper equalization seals arranged on the mandrel and sealingly engageable with the upper seal bore. The shifting tool is engageable with the sliding sleeve to move the downhole device at least partially between a closed position, where a pressure differential between a subterranean formation and an interior of the completion string is assumed by primary sealing elements of the downhole device, and an open position, where the pressure differential is assumed by at least the upper equalization seals.

Abstract:

A method and apparatus that includes an elongated base pipe having an external surface at least partially defining an external region and an internal surface at least partially defining an internal region; and a pressure maintenance device disposed in the base pipe and includes a first flow path that extends between an opening in the external surface and an opening in the internal surface; a first valve that controls the flow of a first fluid through the first flow path; a first pressure differential sensor that controls the actuation of the first valve and is in fluid communication with the external region; and a pressurized fluid source in fluid communication with the first pressure differential sensor; wherein a first pressure differential threshold associated with the first pressure differential sensor is the difference between a pressure within the external region and the pressurized fluid source.
