Patent number: 10294754Abstract: A bottom hole assembly for performing a borehole treatment has a plurality of ported valve housings where the housings have an assembly of shifting sleeves. The first sleeve is shifted uphole to open the port in the housing and lock the first sleeve in the ports open position. A second sleeve in the same housing is shifted in the same direction as the first sleeve to close the ports in the housing. The second sleeve has profiles for shifting it up to close the housing ports and back down to reopen the housing ports after closing them.Type: GrantFiled: March 16, 2017Date of Patent: May 21, 2019Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Jeffrey B.

Patent number: 10012050Abstract: A system and method for treating a portion of a wellbore that includes a bottom hole assembly (BHA) connected to a work string. The BHA includes a packing element movable between an unset position and a set position and a locator device movable between retracted position and expanded positions. The locator device may be a locator collet. The locator collet may be expanded by a cone movable with respect to the collet. The expanded locator device is configured to engage a profile in a ported tubular within the wellbore. The engagement between the locator device and the profile selectively prevents further movement of the BHA and provides an indication of the location the BHA. The packing element may then be actuated and the wellbore treated through a port in the ported tubular. The BHA may then be moved to a different ported housing to treat another portion of the wellbore.Type: GrantFiled: September 7, 2017Date of Patent: July 3, 2018Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Ian Beckett, Luis A. Castro, Christopher W. Thacker, Jason Harper, Marc Carriere, Leigh Thorne, Jeffrey Koch, Justin Reyes, Bradley Collas, Cory Casemore, David Luft, Orest Zolkavich, Derek Robert Brown
