Patent number: 11091975Abstract: A technique facilitates use of a packer in a borehole or within other tubular structures. The packer may be constructed with a tubing, a metal sealing element mounted around the tubing, and a differential pressure valve system. The metal sealing element may be expanded under fluid pressure for sealing engagement with a surrounding wall surface. Additionally, the differential pressure valve system is placed in fluid communication with the interior of the metal sealing element and comprises a plurality of valves which operate automatically to increase pressure within the metal sealing element when certain pressure differentials occur. The differential pressure valve system enables the packer to hold against higher differential pressures and also may be constructed so the packer is less sensitive to thermal variations.Type: GrantFiled: March 27, 2018Date of Patent: August 17, 2021Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Samuel Roselier, Romain Neveu, Jean-Louis Saltel

Patent number: 10502033Abstract: A method for hydraulic stimulation of rock of a borehole of a well having an internal casing. The method includes positioning a conduit in the casing, the conduit having along its external face expandable tubular sleeves, fixedly linked to the conduit, and at least one aperture before each sleeve placing the internal space of the conduit into communication with the space demarcated by the conduit and each sleeve. A fluid is injected into the conduit under a first pre-determined pressure, which is sufficient to expand the sleeves. For each of the areas of the wall of the well to be stimulated, the method includes: plugging the conduit downstream from a first area to be stimulated; perforating the wall of the conduit and, at least in certain cases, perforating the casing at the first area to be stimulated; and injecting a fluid into the conduit under a second stimulation pressure.Type: GrantFiled: October 16, 2015Date of Patent: December 10, 2019Assignee: SLATEL INDUSTRIESInventors: Jean-Louis Saltel, Samuel Roselier
