Patent number: 10519737Abstract: A bottom hole assembly (BHA) and methods of using the BHA, the BHA having at least one tool configured to move between the interior and the exterior by fluid pumped down a string. The tool is configured to create a hole in a wellbore tubular, such as casing, tubing, or a liner. The BHA includes a ramp positioned adjacent to the tool to guide the tool to engage the tubular. The tool may be a mill configured to cut a hole in the tubular or a punch member configured to punch a hole in the tubular. A packing element of the BHA enables fluid to be pumped down the annulus and through the hole to treat and/or fracture the formation. The tool may be positioned between two packing elements and fluid may be pumped down the string and through a portion of the tool to treat and/or fracture the formation.Type: GrantFiled: November 29, 2017Date of Patent: December 31, 2019Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Darin H.

Publication number: 20110265941Abstract: Tubular is manufactured at a well site to a predetermined size using flat stock that is rolled into a c-shape from a plurality of feed locations. The c-shapes have open segments that are offset from each other to form the tubular shape. A binder material such as a reactive nano-foil is applied on assembly as the tubular shape is formed. The manufactured shape is reduced to a smaller dimension for run in. The cross-sectional reduced profile shape can be a smaller diameter or a crescent or an undulating shape that is triggered to revert to the original manufactured shape and size when placed downhole. The manufacturing method is capable of making continuous pipe for the length of the zone without connections. The bonding of the segments is preferably done at the time of fabrication at the well site but can also occur at least in part downhole.Type: ApplicationFiled: April 29, 2010Publication date: November 3, 2011Applicant: BAKER HUGHES INCORPORATEDInventors: Dennis G.
