Abstract:
A stabilizer (36) mounted on a mandrel (14) of a workstring (12) within a casing (10) of a well bore hole. The stabilizer (36) has an upper carrier (38) fixed to the mandrel (14) and a lower carrier (40) mounted on the mandrel (14) for relative sliding movement. Shoes (70) are mounted by links or arms (64, 74) to bearing housing (50, 80) on the carriers (38, 40). The bearing housings (50, 80) are mounted for relative rotation on the carriers (38, 40) and permit the mandrel (14) and workstring (12) to rotate relative to the shoes (70) upon fluid actuation of lower carrier (40) and engagement of the casing (10) by the shoes (70).
Abstract:
A debris removal tool has a lower end pickup hose into which debris laden fluid is pulled when there is circulation through the debris removal tool from the surface. An anchor near the open end of the hose stabilizes the lower end near a recess or groove from which debris is to be removed. Once the anchor is set the hose can be extended or retracted as well as rotated on its axis to pick up debris. A camera can be located in or near the hose opening to be able to see where the debris is located and for confirmation that the debris is being removed and that the debris has fully been removed.
Abstract:
A debris removal device features structural support from an exterior housing that allows more space for debris collection. The debris enters the collection volume from the top to eliminate debris from having to go through a valve. The screen in the device is disposed internally to protect it during handling and running. A variety of external flow diverters are used to direct debris laden fluid into the tool and to keep debris out of an annular space around the tool that could interfere with its removal. The diverters can be actuated by relative movement in the tool or applied pressure to a piston which can inflate a sleeve or orient or misalign paths through brushes for selective bypassing of fluid exterior to the tool.
Abstract:
In one aspect, a method of method of performing a wellbore operation is disclosed that in one embodiment may include: providing a device that includes a non-explosive energetic material configured to disintegrate when subjected to a selected energy; placing the device at a selected location in the wellbore to perform a selected function; and subjecting the device to the selected energy to disintegrate the device in the wellbore after the device has performed the selected function. In another aspect an apparatus for use in a wellbore is disclosed that in one embodiment may include a device placed in the wellbore at a selected location, wherein the device includes a non-explosive energetic material configured to disintegrate when subjected to a selected energy, and a source of the selected energy configured to subject the device to the selected energy in the wellbore to disintegrate the device.
Abstract:
A downhole cutting tool includes a base including a first consolidated powder; and at least one cutting feature affixed to the base, the at least one cutting feature including a cutting material suspended in a second consolidated powder, wherein the base and the at least one cutting feature are both consolidated and bonded together simultaneously. Also included is a method of manufacturing a cutting tool.
Abstract:
An apparatus for verifying cement arrival at a target location includes a liner. A sensory structure radially outwardly disposed of the liner at a target arrival location of cement from a cementing operation. The sensory structure configured to sense arrival of cement. A seal configuration automatically responsive to the sensed arrival of cement. Also included is a method for addressing micro annulus formation in a down hole cementing operation.
Abstract:
The disclosure, in on aspect, provides a method for performing a laser operation in a wellbore that includes displacing a wellbore fluid with a laser-compatible medium proximate a location in the wellbore where a work is desired to be performed; positioning a laser head proximate the laser-compatible medium; and passing a laser beam via the laser-compatible medium to the location for performing the laser operation. In another aspect, the disclosure provides a laser apparatus for performing a laser operation at a worksite having a fluid that includes a laser power unit that supplies laser energy to a laser head placed proximate the worksite; a fluid displacement unit that displaces at least a portion of the fluid adjacent the worksite with a laser-compatible medium; and a controller that operates the laser head to pass the laser beam to the worksite through the laser-compatible medium. In another aspect, the disclosure provides an imager associated with the laser apparatus that provides images of the worksite.
Abstract:
A debris cleanup tool uses an eductor principle to induce flow into a lower end to bring debris into a housing where the debris will either settle out or be screened out and the remaining fluid drawn up into the eductor with motive force for the eductor coming from clean fluid pumped down a tubular string from the surface. The eductor performance is enhanced with a surrounding sleeve on the eductor outlet that directs eductor exhaust flow into an annular passage oriented in a downhole direction. The exterior of the sleeve has passages to allow some of the flow to go uphole while the sleeve wall has ports through it to allow flow in the annular passage to cut through to outside the sleeve for passage uphole or downhole.
Abstract:
A downhole tubular scraper is run in on slickline with an on board power supply. It features counter-rotating scrapers without an anchor in one embodiment or an anchor with single rotating scrapers. The scraper is selectively operated to conserve power in the power supply. A drive system uses a single driver to obtain counter-rotating motion in the scrapers.
Abstract:
An anchoring system including a housing; a chamber defined by the housing; and one or more telescopic assemblies disposed in contact with a wall of the housing and responsive to pressure within the chamber and a method for anchoring a tool in a wellbore.
