Publication number: 20080017368Abstract: A wellhead has, instead of a conventional Christmas tree, a spool tree (34) in which a tubing hanger (54) is landed at a predetermined angular orientation. As the tubing string can be pulled without disturbing the tree, many advantages follow, including access to the production casing hanger (21) for monitoring production casing annulus pressure, and the introduction of larger tools into the well hole without breaching the integrity of the well.Type: ApplicationFiled: August 31, 2007Publication date: January 24, 2008Applicant: CAMERON INTERNATIONAL CORPORATIONInventors: Hans Hopper, Thomas Cassity

Publication number: 20050152749Abstract: The present invention relates to a guide device for an off-shore drilling installation comprising at least one drilling riser extending from a floating support to a said guide device at the sea bottom, said drilling being performable from said floating support via said drilling riser using a drill string fitted at its end with drilling tools. According to the invention, said telescopic guide device comprises a telescopic guide pipe comprising coaxial telescopic pipe elements about an axis, the smallest-diameter innermost telescopic pipe element being fitted at its end for breaking up the ground suitable for progressively burying said telescopic guide pipe in the ground so as to enable a drilling tool to be guided more deeply into the ground.Type: ApplicationFiled: June 18, 2003Publication date: July 14, 2005Inventors: Stephane Anres, Hans Hopper

Publication number: 20050061515Abstract: Methods and apparatus for flowing a subsea well. The method comprises the steps of: supplying a multi-phase medium from a subsea tree 18 to a removable separator package 10; separating the multi-phase flow into one or more phases at the desired pressures, the pressures being controlled by one or more pressure control devices 51, 67, 71, 75, 76, 77, 78, 79 on one or more outlets from the separator package 10; and analysing each of the one or more phases to determine the amount and quality of products produced by the well.Type: ApplicationFiled: September 14, 2004Publication date: March 24, 2005Applicant: Cooper Cameron CorporationInventor: Hans Hopper

Publication number: 20050061499Abstract: A removable seal 10 is provided for positioning in a bore 14 around an element which, in use, passes therethrough. The seal comprises: a cylindrical outer sleeve 13 having an axial bore, the sleeve 13 having at least one engagement portion for engaging, in use, with an internal surface of the bore 14; and a sealing element 17 mounted on the cylindrical outer sleeve 13 for, in use, extending into the axial bore 14 to seal around the element passing therethrough.Type: ApplicationFiled: September 8, 2004Publication date: March 24, 2005Inventor: Hans Hopper

Publication number: 20050055163Abstract: It is important to know the precise position of equipment when testing of the BOP, testing the wellhead, flow testing the well, kick control, well circulation and testing of spool trees between the wellhead and the BOP. Accordingly, there is provided a system for determining the real time position of equipment within a bore, the system comprising: a data input means for inputting data concerning the physical characteristics of components which are run into the bore; a sensing means located, in use, within the bore and including a sensor for determining data concerning at least one physical characteristic of the equipment at a given time; a data storage means for recording the inputted data and the determined data; and a comparison means for comparing the input data and the determined data to establish which part of the equipment is being sensed by the sensor.Type: ApplicationFiled: November 27, 2002Publication date: March 10, 2005Applicant: COOPER CAMERON CORPORATIONInventor: Hans Hopper

Patent number: 4567762Abstract: A thermoelectric level detector employs an impedance element, at least a portion of which is meandering in configuration in which the resistive path repeatedly traverses the axis thereof, to detect the level of liquid in a tank. The impedance of the element depends on temperature and provides a measure of the liquid level. The pitch of the meander is relatively small in the reserve region of the tank to provide fine resolution in this region.Type: GrantFiled: February 19, 1982Date of Patent: February 4, 1986Assignee: Telefunken electronic GmbHInventors: Hans Hopper, Dieter Busch, Fritz Sondermann, Fritz Stork
