Patent number: 8613309Abstract: When inserting a tube into a borehole in the ground for extracting minerals, tube parts are successively added to the proximal end of the tube while the tube reaches into the borehole. Thereafter, the tube is inserted further into the borehole. As the addition of the tube part is carried out by welding, each time an eminently sealing and slender joint between the tube parts is obtained. As the tube parts are successively added to the tube only when this is necessary for inserting the tube further into the ground, winding up the tube to store it prior to insertion is not necessary and the use of a tube-carrying reel which is difficult to handle is thus rendered redundant. Further, an installation for carrying out the proposed method is described.Type: GrantFiled: January 19, 2000Date of Patent: December 24, 2013Assignee: Shell Oil Company & B.J.

Patent number: 8479830Abstract: Apparatus and a method for deploying a wireline tool in a borehole. The apparatus comprises a wireline cable which is connected at a first end at the surface and is releasably connected at a second end to a first end of an umbilical cable via a first connection means. A second end of the umbilical cable is releasably connected to the logging head of a wireline tool via a first latching means, wherein the logging head provides for mechanical and electrical connection between the wireline tool and the wireline cable via the umbilical cable. The umbilical cable is surrounded by umbilical pipe downhole, and the logging head also provides for mechanical and hydraulic connection between the umbilical pipe and the wireline tool. The wireline tool is releasable from connection with the umbilical cable by a release means in the first latching means, and is capable of being pulled through the first latching means and through the umbilical pipe so that it is retrievable from the borehole.Type: GrantFiled: November 20, 2008Date of Patent: July 9, 2013Assignee: Schlumberger Technology CorporationInventors: Henri Denoix, Charles Deible

Publication number: 20130168107Abstract: Control lines are secured to a completion string by a wrap wound around the completion string and control lines. The control lines are positioned adjacent to the completion string as it is lowered towards a well, and the wrap is wound helically around the lines and string in an open or closed loop manner. The placement and pitch of the wrap may be regulated, such as based upon the rate of advancement of the string into the well. One or multiple wraps may be used, and successive turns of the one or more wraps may overlap or be spaced from one another.Type: ApplicationFiled: December 5, 2012Publication date: July 4, 2013Applicant: TESCO CORPORATIONInventor: TESCO CORPORATION

Publication number: 20130133898Abstract: To deploy a capillary string through a wellhead to a downhole safety valve, a control port and a retention port are drilled in an adapter between a casing hanger and a gate valve or elsewhere. The capillary string is connected to a first port of a capillary hanger and installed through the wellhead. The capillary hanger is landed on a tubing hanger, and a side port on the capillary hanger communicates with the control port. Because the side port's location may not align with the control port, operators may need to measure how long the capillary hanger should be. A control line connects to the control port in the wellhead's side to communicate with the capillary line, and a retention rod inserts in the retention port to support the capillary hanger.Type: ApplicationFiled: July 14, 2012Publication date: May 30, 2013Inventors: Todd Travis, Brandon Cain, Eric Calzoncinth, Paul Perez

Patent number: 8439109Abstract: A technique enables determination of changes in length of a conveyance deployed between a surface vessel and a subsea installation. The technique allows information to be obtained on the relationship between length of conveyance spooled out or spooled in at a surface location and the depth and/or speed of an intervention well tool deployed in a well. The information can be used to determine the actual depth of the well tool deployed in the well for the intervention operation.Type: GrantFiled: May 23, 2008Date of Patent: May 14, 2013Assignee: Schlumberger Technology CorporationInventor: Andrea Sbordone
