| 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 |
| 20110056704 | METHOD AND DEVICE FOR CASING A BORED WELL PORTION - The invention comprises using a tube having a ductile and radially expansible upper portion, provided at the base thereof with a seal that is also radially expansible under the action of the weight of the tube, the latter being thus sized so that when its base abuts the bottom of the well, the upper portion is located above a fractured area to be isolated, the procedure comprising the following steps: the tube is inserted into the well so that the base thereof bears against the bottom, triggering the radial expansion of the seal; using an expansion tool, the upper portion of the tube is radially expanded beyond its yield strength in order to apply the same tightly against the wall of the well above the fractured area. The invention can be used in the petroleum industry. | 03-10-2011 |
| 20100243234 | A CONTROL DEVICE FOR AN INFLATABLE TOOL FOR THE TREATMENT OF A WELL OF A PIPE - The invention relates to device for controlling an inflatable tool used to treat a well or pipeline. The device, which is inserted between the outlet of a fluid supply pipe and the tool, comprises: a chamber communicating with the exterior through a tube and with the tool via a pipeline; and a piston mounted in said chamber, which, under the force of a spring, normally occupies a first position in which it seals the outlet of the pipe, the aforementioned tube then communicating with the pipeline. The pipeline is provided with at least one spring-loaded check valve which allows the passage of the pressurised fluid from the chamber to the tool when the pressure upstream of the valve exceeds a predetermined threshold value, which prevents the passage of the fluid in the opposite direction. | 09-30-2010 |
| 20100193124 | Method of Lining a Well or a Pipe Using an Inflatable Bladder - According to the method, a cylindrical tube ( | 08-05-2010 |
| 20100163254 | Device For Sealing Off A Well And A Pipe And A Fitting Method - The invention relates in particular to a device for sealing off a well or a pipe, that comprises a tubular sleeve that can be radially expanded by an inflating fluid, in order to press hermetically against the wall of the well or pipe, which sleeve is connected to end members, at least one of which comprises an annular skirt directed towards this sleeve. It is characterized essentially in that the skirt wall has a number of through-holes therein and in that the material of the sleeve surrounds said skirt in such a way as to cover its outside and inside faces, sealing said holes and leaving no gaps. | 07-01-2010 |
| 20100132952 | METHOD FOR CASING USING MULTIPLE EXPANDED AREAS AND USING AT LEAST ONE INFLATABLE BLADDER - The method of the invention comprises inserting into the well or the piping to be cased, a tube ( | 06-03-2010 |
| 20090309356 | Flexible Pipe Having Integrated End Fittings - A flexible pipe comprising a flexible cylindrical tubular pipe body connected at each of its ends to a rigid connector end fitting in the form of a sleeve. The wall of the pipe body is mechanically reinforced by at least one traction layer of filaments of small thickness, presenting high traction strength, that are wound helically about the longitudinal axis of the pipe. The traction layer is composed of an array of uninterrupted filaments interconnecting the two end fittings alternately in one direction and then in the other direction, while being fastened on the end fittings. | 12-17-2009 |
| 20090188569 | METHOD AND APPARATUS FOR PATCHING A WELL BY HYDROFORMING A TUBULAR METAL PATCH, AND A PATCH FOR THIS PURPOSE - A method of patching a well or a pipe by hydroforming a tubular metal patch. A tool provided with a pair of inflatable packers is inserted inside the patch. The pair of inflatable packers are axially spaced apart from each other by a distance that is substantially equal to the length of the patch. The tool is positioned inside the patch so that the packers are in register with the end portions of the patch. The assembly of the tool and the patch is axially inserted inside the well or the pipe, and positioned in register with the zone for patching. The packers are inflated to a high pressure, sufficient for radially expanding the end portions of the patch and pressing them in a leak-tight manner against the wall of the well or the pipe. The packers are subsequently deflated and the tool is withdrawn. The method is applicable to the oil industry. | 07-30-2009 |
