Patent number: 11851983Abstract: A rupture apparatus (50) often deployed within a wall of a casing string (53) of an oil and gas well, comprising a housing (51) defining a housing bore (54) with a bore inlet and a bore outlet; a carriage carrying a rupturable component (12) the carriage being moveable in the housing bore between a rupturable position, an open and a closed position. Thus the bore can be opened or closed or closed subject to rupture of the rupturable component (12). Moreover, after rupture the bore can still be closed. Wireless signals are normally used to for control, especially electromagnetic or acoustic signals. A pressure balancing port (6) may be defined in a wall of the housing allowing fluid communication between at least a portion of the housing bore, and an outside of the housing which can pressure-balance the carriage such that it remains stationary unless actuated.Type: GrantFiled: March 16, 2020Date of Patent: December 26, 2023Assignee: METROL TECHNOLOGY LIMITEDInventors: Shaun Compton Ross, Leslie David Jarvis, David Glen Martin

Patent number: 10184302Abstract: Apparatus and method for sealingly connecting tubular members in a wellbore. In a connector apparatus where a portion of a tubular member is radially expanded into sealing contact within a second tubular member, and the second tubular member has circumferential recesses on an inner surface, an annular resilient band member is arranged in the recesses. The annular resilient band member is acted on by the portion of the tubular member during expansion and maintains sealing contact to the portion after expansion.Type: GrantFiled: August 10, 2015Date of Patent: January 22, 2019Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Neil Thomson, Peter Wood, Daniel O'Brien, David Glen Martin, William Luke McElligott

Patent number: 10125567Abstract: A morphable packer and method of setting the packer in a wellbore. The packer is a tubular member having a throughbore with a central portion having a greater diameter than each end portion with tapered portions there between. Gripping elements are arranged on the tapered portions. Morphing of the tubular member creates a seal between the central portion and an outer cylindrical structure, such as a wellbore or casing, and the gripping elements are moved radially outwards to engage with the cylindrical structure. The gripping elements act as slips which are activated by morphing the tubular member. Embodiments are described with the tubular member being a sleeve on a base pipe and, additionally, sealing and securing features in the form of elastomeric bands, lugs and wedges.Type: GrantFiled: September 29, 2015Date of Patent: November 13, 2018Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: David Glen Martin, Peter Wood, William Luke McElligott

Patent number: 10094495Abstract: A pipe coupling make up assembly and a method of making up a pipe coupling between tubular sections at a well. A first tubular section in a tubular string at the well is gripped and supported in the assembly. A second tubular is supported and moved to locate a first end of the second tubular section into an expanded first end of the first tubular section. A swaged die is arranged around the first tubular section and forced along the first tubular section towards the second tubular section. This causes the expanded first end to move radially inwards under elastic and plastic deformation and create a metal to metal seal between the first ends of the first and second tubular sections.Type: GrantFiled: August 3, 2015Date of Patent: October 9, 2018Assignee: MORPHPACKERS LIMITEDInventors: Michael Ledingham, David Glen Martin

Patent number: 9863208Abstract: An assembly having a sleeve member located over a tubular body, there being a chamber between the two and by increased pressure in the chamber the sleeve member is morphed to secure it to a well bore wall and create a seal between the sleeve and well bore wall to form an isolation barrier. The tubular body is formed in one or more sections so that annular planar faces are created for abutment between the sleeve member and the tubular body so as to remove the requirement for complex fittings and reduce the time of construction.Type: GrantFiled: October 21, 2015Date of Patent: January 9, 2018Assignee: MORPHPACKERS LIMITEDInventors: David Glen Martin, Davidson Harman, Cameron Radtke, Peter Wood, William Luke McElligott

Patent number: 9840878Abstract: Apparatus and method for sealingly connecting tubular members in a wellbore. In an arrangement where a portion of a tubular member is radially expanded into sealing contact within a second tubular member, and the second tubular member has circumferential recesses on an inner surface, a resilient member protrudes from a side wall of the recesses. The resilient member is acted on by the portion of the tubular member during expansion and maintains sealing contact to the portion after expansion.Type: GrantFiled: August 7, 2015Date of Patent: December 12, 2017Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: David Glen Martin, William Luke McElligott

Patent number: 9752419Abstract: A hydraulic fluid delivery tool for morphing a tubular downhole and a method of morphing a tubular downhole. The tool has spaced apart annular elastomer seal assemblies which operate by application of a piston against each elastomer to create a seal against the tubular. A first hydraulic fluid delivery line delivers fluid at a first pressure to operate the pistons. A second hydraulic fluid delivery line delivers fluid at a second pressure, lower than the first, to a location between the seals to morph the tubular and act on a second face of each piston to assist in maintaining the seal.Type: GrantFiled: September 27, 2015Date of Patent: September 5, 2017Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: David Glen Martin, Neil Thomson

Publication number: 20150337616Abstract: An apparatus and method for securing a tubular within another tubular or borehole, creating a seal across an annulus in a well bore, and centralising or anchoring tubing within a wellbore. A sleeve is arranged on a tubular body to create a chamber therebetween. A port provides fluid access through the body to the chamber. Each end of the sleeve is covered by a cylindrical portion of a connector. When fluid is introduced into the chamber the sleeve is morphed to secure it to a well bore wall and the ends of the sleeve are morphed to each cylindrical portion. The connection between the sleeve and body does not require a weld. The cylindrical portions may also be shrink fitted to the ends of the sleeves.Type: ApplicationFiled: May 20, 2015Publication date: November 26, 2015Inventors: William Luke McGelligott, Damien Gerard Patton, David Glen Martin
