Patent number: 9874066Abstract: 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. The sealing bodies may be non-integral with each other and/or separable from each other.Type: GrantFiled: December 16, 2011Date of Patent: January 23, 2018Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Pierre-Yves Corre, Jean-Louis Pessin, Stephane Metayer, Stephen Yeldell

Patent number: 9644478Abstract: 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: GrantFiled: December 20, 2011Date of Patent: May 9, 2017Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Pierre-Yves Corre, Stephane Metayer, Alexander F.

Patent number: 9181771Abstract: A packer assembly with an enhanced sealing layer is provided. The packer assembly may have an outer bladder with drains. The packer assembly may further have an inflatable inner packer disposed inside the outer bladder such that inflation of the inner packer causes the outer bladder to expand. End pieces may be coupled to the inner bladder and the outer bladder, and flowlines may be in fluid communication with the drains and the end pieces. A piston ring may reinforce the packer assembly. The piston ring may have three or more passive pistons which expand with the packer assembly during testing.Type: GrantFiled: October 5, 2012Date of Patent: November 10, 2015Assignee: Schlumberger Technology CorporationInventors: Pierre-Yves Corre, Jean-Louis Pessin, Julian Pop, Stéphane Metayer, Stephen Yeldell

Patent number: 9097107Abstract: 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: GrantFiled: July 23, 2013Date of Patent: August 4, 2015Assignee: Schlumberger Technology CorporationInventors: Pierre-Yves Corre, Edward Harrigan, Alexander F.

Patent number: 8919460Abstract: A coring tool having a coring mechanism for cutting cores from a borehole sidewall. The coring mechanism comprises a motor having a coring bit to cut 1.5 inch diameter, 2.5 inch long cores. Support plates fixed to the housing comprise guide slots having a longer leg and a shorter leg. Leading pins and follower pins extend from the motor into the guide slots. When the leading and follower pins are driven along the guide slots, the motor is rotated and then pushed into the formation. Drive plates positioned between the housing and the support plates comprise slots and pivot about a pin. The leading pins further extend into the drive plate slots. A hydraulic cylinder pivots the drive plates, pushing the pins along the guide slots to rotate the motor to a radial position and then urge the motor towards the formation.Type: GrantFiled: September 11, 2012Date of Patent: December 30, 2014Assignee: Schlumberger Technology CorporationInventors: Sebastien Joulin, Stephen Yeldell, Brandon Christa, James Massey
