20110100499 | FLEXIBLE PIPE WITH IN-BUILT END PIECES - This flexible pipe comprises a versatile and flexible tubular body (PP) which comprises, from the outside toward the inside, a pressure arch ( | 05-05-2011 |
20120211222 | DEVICE FOR APPLYING AN EXPANDABLE SKIRT HAVING APPLICATION DIAMETER CONTROL UPON ADVANCE - The present invention relates to a device for laying an expansible lining in a conduit. The device may include a patch having an initial diameter less than that of the conduit, and the patch may be configured to deform by radial expansion beyond an elastic limit to an expanded diameter such that it may contact a wall of the conduit. The device may also include an expander tool axially displaceable inside the patch, and the expander tool may be configured to cause the radial expansion of the patch to an expanded diameter. The device may also include a checking member mounted in proximity to the expander tool. A section of the checking member may be calibrated so that the checking member and the expander tool are capable of passing freely inside the patch when the patch is properly expanded, and the checking member and the expander tool are unable to pass inside the patch when the patch is improperly expanded. | 08-23-2012 |
20130140022 | Method For Repairing A Liner Hanger, Device And Blank For Implementation Thereof - Method for repairing a hanger (D) of a liner (B), for making a leak-tight connection, the liner (B) being placed inside and in the continuation of the casing (A) of a well, the method consisting in axially positioning a metal tubular blank ( | 06-06-2013 |
20130146308 | Support Device Of Equipment Inside A Well, A Process For Fixing It And A Process For Placing Such Equipment - The present invention relates to a support device for tubular equipment, such as a liner inside a well, said support device including two elements attached to each other, comprising: a) a cylindrical sleeve, made of ductile metal, the cylindrical sleeve having an external diameter slightly less than an inner diameter of the well or of a casing inserted into the well; b) a set of tabs made of hard metal, which are spaced apart from each other and integral with the cylindrical sleeve, the tabs extending downwards from the cylindrical sleeve, wherein an outer wall of the tabs is fitted with a series of notched formations, such as teeth, whereas an inner wall of the tabs has a conical form, the apex of which is turned down. Methods of using the aforementioned support device are also disclosed. | 06-13-2013 |
20130240202 | ISOLATION DEVICE OF PART OF A WELL - The invention relates to isolation of part of a well, which comprises pipe provided, along its external face, with a first external sleeve, wherein the opposite ends are connected directly or indirectly to said external face of the pipe. The pipe, first external sleeve and its ends together delimit an annular space, the wall of said pipe exhibiting at least one opening which allows it to communicate with said space, this sleeve being likely to expand and to be applied tightly against the well over an intermediate part of its length. The device also comprises on the one hand, a second internal sleeve, which extends between said pipe and the first sleeve, its ends being also connected directly or indirectly to the external face of said pipe and, on the other hand, at least one communication passage between the exterior of the first sleeve and said space. | 09-19-2013 |
20150075818 | PIPE PROVIDED WITH A CRIMPED METAL ELEMENT, AND CORRESPONDING PROCESS - A pipe designed to be placed within a well for producing a fluid of interest, a pipe onto the outer face whereof is crimped a tubular metal element, wherein:
