Publication number: 20140020890Abstract: A sampling assembly of a single packer assembly may have more guard drains than sampling drains. The single packer assembly having the sampling assembly may be deployed in a wellbore formed in a subterranean formation, and the single packer assembly may be deployed on a wireline cable or another deployment or conveyance. The number and the area of the sampling drains, the number and the area of the guard drains, and the positions of the sampling drains and the guard drains may be designed so that the guard drains which are operational may provide a fluid intake rate exceeding a predetermined threshold if one of the guard drains is congested and/or blocked.Type: ApplicationFiled: December 20, 2011Publication date: January 23, 2014Applicant: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Pierre-Yves Corre, Stephane Metayer, Alexander F.

Publication number: 20140008061Abstract: A packer assembly has an inner expandable packer. An outer layer having sealing bodies may be disposed about and/or positioned on the outer surface of the inner expandable packer member. Each of the sealing bodies may have an elastomeric body, and one or more flowlines may be embedded in the elastomeric body of each of the sealing bodies. The sealing bodies may be located in grooves in the inner expendable packer member. The sealing bodies may contact a surrounding casing or a surrounding formation to form an annular seal; in an embodiment, the sealing bodies and the inner expandable packer member may contact a surrounding casing or a surrounding formation to form an annular seal.

Publication number: 20130306309Abstract: A technique involves collecting formation fluids through a single packer having at least one drain located within the single packer. The single packer is designed with an outer structural layer that expands across an expansion zone to facilitate creation of a seal with a surrounding wellbore wall. An inflatable bladder can be used within the outer structural layer to cause expansion, and a seal can be disposed for cooperation with the outer structural layer to facilitate sealing engagement with the surrounding wellbore wall. One or more drain features are used to improve the sampling process and/or to facilitate flow through the drain over the life of the single packer.Type: ApplicationFiled: July 23, 2013Publication date: November 21, 2013Applicant: Schlumberger Technology CorporationInventors: Pierre-Yves Corre, Edward Harrigan, Alexander F.

Patent number: 8336181Abstract: A technique enables construction of a simplified inflatable packer. An inflatable packer is constructed with a packer reinforcement layer having at least one fiber layer. The fiber layers provide both mechanical and anti-extrusion qualities in a relatively simple and small package. Depending on the desired application, the inflatable packer also comprises an inner bladder layer and other potential layers, such as an outer seal layer. Mechanical extremities are used to secure longitudinal ends of the various packer layers, including the packer reinforcement layer.Type: GrantFiled: December 7, 2009Date of Patent: December 25, 2012Assignee: Schlumberger Technology CorporationInventors: Pierre-Yves Corre, Gilles Carree, Guillaume Boutillon, Zeynep Alpman, Stephane Metayer, Jean-Louis Pessin

Patent number: 7699124Abstract: A technique involves collecting formation fluids through a single packer having at least one drain located within the single packer. The single packer is designed with an outer layer that expands to create a seal with a surrounding wellbore wall. The drain is located in the outer layer between its axial ends for collecting formation fluid which is routed from the drain to an axial end of the outer layer via a fluid flow passage. Mechanical fittings are mounted at the axial ends of the outer layer, and at least one of the mechanical fittings comprises one or more flow members coupled to the flow passage to direct the collected fluid from the packer. The one or more flow members are designed to move in a manner that freely allows radial expansion and contraction of the outer layer.Type: GrantFiled: June 6, 2008Date of Patent: April 20, 2010Assignee: Schlumberger Technology CorporationInventors: Pierre-Yves Corre, Stephane Metayer
