162 | METHOD OF SEALING A FRACTURE IN A WELLBORE AND SEALING SYSTEM | EP15707376.8 | 2015-03-03 | EP3114306A1 | 2017-01-11 | VAN DONGEN, Hans Johannes Cornelis Maria |
In a method of sealing a fracture (1) in a formation (2) surrounding a wellbore provided with a non-cemented perforated liner (4), a placement tool (6) is introduced into the liner, and a first and second annular flow barrier (8, 9) create an upstream (10), an intermediate (11) and a downstream section (12). A cross flow shunt tube (13) connects the upstream section and the downstream section, and a sealing fluid outlet (14) is arranged in the intermediate section. A placement fluid is caused to flow into the fracture and controlled to obtain a desired fluid flow in an annular space between the liner and the formation that is directed in downstream direction at a position upstream the fracture and in the upstream direction at a position downstream the fracture. When said desired flow is obtained, sealing fluid is ejected from the sealing fluid outlet. A sealing system is furthermore disclosed. | ||||||
163 | HIGH PRESSURE LARGE BORE WELL CONDUIT SYSTEM | EP13793591 | 2013-03-01 | EP2820338A4 | 2016-08-03 | TUNGET BRUCE A |
Well conduit system and methods using a first outer conduit wall and at least one second inner conduit wall positioned through a wellhead to define an annulus with radial loading surfaces extending across the annulus and radially between at least two of the conduit walls to form passageways through subterranean strata concentrically, wherein an inner pipe body of greater outer diameter is inserted into an outer pipe body of lesser inner diameter by elastically expanding the circumference of the outer pipe body and elastically compressing the circumference of the inner pipe body, using a hoop force exerted therebetween. Releasing the hoop force after insertion will release the elastic expansion and compression of the pipe bodies to abut the radial loading surfaces within the annulus for sharing elastic hoop stress resistance and thereby forming a greater effective wall thickness, capable of containing higher pressures than the conduit walls could otherwise bear. | ||||||
