Patent number: 10648287Abstract: A downhole tool, configured to receive a milling tool or other forcing tool, includes: a tubular mandrel; an adapter housing coupled to the mandrel; a guide sleeve disposed within the adapter housing; a movable sleeve configured for sliding movement within the guide sleeve; and a retainer positioned uphole of the movable sleeve. The retainer includes an upper annular portion, a lower annular portion, an annular void between the upper and lower annular portions, and a bridge portion extending between the upper and lower annular portions. The upper annular portion is initially fixed to the guide sleeve. The lower annular portion is configured such that downward movement of the lower annular portion causes the movable sleeve to move downward within the guide sleeve. The bridge portion comprises a through-passage and a thin walled segment adjacent to the void. Milling or otherwise disconnecting the bridge portion permits the lower annular portion to move the moveable sleeve.Type: GrantFiled: September 26, 2017Date of Patent: May 12, 2020Assignee: DRECO ENERGY SERVICES ULCInventors: Graham S.

Patent number: 10590705Abstract: A downhole motor has a bearing mandrel rotatably disposed within a housing, plus an impact adapter disposed above and connected to the bearing mandrel and rotatable therewith. The impact adapter has upwardly-projecting teeth engageable with downwardly-projecting teeth on a drive mandrel disposed above and coaxially aligned with the impact adapter. The drive mandrel is both rotatable and axially movable within the housing, and relative to the impact adapter. By means of a cam assembly and a helical spring (or other energy storage means) associated with the drive mandrel, rotation of the drive mandrel causes upward movement of the drive mandrel within the housing, thus compressing the spring. Further rotation causes instantaneous dropping of the drive mandrel, releasing energy stored in the spring, and causing the application of rotational and/or axial impacts to the bearing mandrel, and thus to a drill bit connected to the bearing mandrel.Type: GrantFiled: March 24, 2016Date of Patent: March 17, 2020Assignee: Dreco Energy Services ULCInventors: Mark Sheehan, Jonathan Prill

The tool comprises a mandrel connected to the conveyance string; an actuation housing slidably shiftable axially along the mandrel between an uphole position, at least one intermediate position and a downhole position; an uphole device operable between an activated position when the actuation housing is in the uphole position, and a deactivated position; and a downhole device operable between an activated position when the actuation housing is in the downhole position, and a deactivated position. Both the uphole and downhole devices are in their deactivated positions when the actuation housing is in the at least one intermediate position. The tool has a J-slot mechanism operable between the actuator housing and the mandrel for shifting the actuator housing between the uphole, at least one intermediate, and downhole positions.Type: GrantFiled: June 10, 2016Date of Patent: January 28, 2020Assignee: Dreco Energy Services ULCInventor: Graham Styler

Patent number: 10358894Abstract: It has been found that in many instances it is desirable to be able to determine where fluid in a well originates. To that end a tracer assembly is provided where the tracer assembly becomes a portion of the tubular that is run into the wellbore. Preferably the tracer assembly provides an exterior barrier whether permanent or temporary to fluid flow outside of the tubular and also provides an interior barrier to fluid flow as it passes through the inner bore of the tubular. The interior barrier is adjustable so that upon command it provides access from the interior of the tubular to at least a portion of a cavity within the tracer assembly. The cavity is provided with a tracer or tracers so that as fluid is allowed within the interior cavity portion of the tracer is eroded, dissolved, or otherwise mixed with the fluid and the tracer that is now mixed with the fluid is transported to the surface.Type: GrantFiled: December 11, 2015Date of Patent: July 23, 2019Assignee: DRECO ENERGY SERVICES ULCInventor: Vincenzo Barbato

Patent number: 10323482Abstract: A flow-actuated pressure equalization valve, for use with a downhole tool such as a treatment tool, for use in stimulating a subterranean formation. The equalization valve allows the pressure of treatment fluid above and below an isolation device to be equalized so the treatment tool can be moved. The valve can be closed when fluid flow exceeds a certain threshold and the treatment tool is set in the wellbore. While running in or pulling out of hole, the valve will not close regardless of the rate of fluid flow. The valve can be opened by stopping fluid flow and then bleeding off pressure above the isolation device, or by pulling up on the treatment tool.Type: GrantFiled: March 31, 2015Date of Patent: June 18, 2019Assignee: DRECO ENERGY SERVICES ULCInventors: Graham Styler, Lewis Facca

Patent number: 10294748Abstract: A wellbore dart or pill is provided such that each time the dart passes through a downhole tool having a seat, an externally extending finger is forced radially inward into the dart. As the finger moves inward to its depressed position, the finger moves a ball or other placeholder from a first position to a second position. When the ball is moved to the second position it may be released into the interior of the well bore or into a chamber in the tool. Once each of the balls have been released from the second position the finger is locked radially outward causing the dart to land and be locked in place at the next seat that is encountered by the dart.Type: GrantFiled: June 9, 2015Date of Patent: May 21, 2019Assignee: Dreco Energy Services ULCInventors: Vincenzo Barbato, Richard Westgarth

Patent number: 10280707Abstract: A re-closable toe sleeve is disclosed where the toe sleeve has a port allowing fluid access from the interior of the toe sleeve to the exterior of the toe sleeve. A burst disk is placed inside the port to prevent fluid access from the interior of the toe sleeve to the exterior of the toe sleeve. However upon the fluid in the interior of the toe sleeve reaching a predetermined level the burst disk is removed or otherwise modified to allow fluid access through the port. A sliding sleeve is placed within the toe sleeve so that the sliding sleeve can be moved to cover the port thereby preventing fluid access from the interior of the toe sleeve to the exterior of the toe sleeve or the sliding sleeve may be moved to uncover the port thereby allowing fluid access from the interior of the toe sleeve to the exterior the toe sleeve. The sliding sleeve is mechanically moved from the surface and is typically run into the well in the open position such that the port is uncovered by the sliding sleeve.Type: GrantFiled: April 8, 2015Date of Patent: May 7, 2019Assignee: Dreco Energy Services ULCInventors: Graham Styler, Gavin MacMillan
