Patent number: 9580990Abstract: A downhole tool having a first packing element and a second packing element configured to synchronically set to selectively hydraulically isolate a portion of the wellbore. The lower packing element may be first set against the well with the upper packing element next being set against the well. A slip joint permits a change in distance between the packing elements during the setting of the packing elements. The slip joint may be energized to apply a force to the lower packing element to prevent the unsetting of the lower packing element during the setting of the upper packing element. A resilient member may be used to energize the slip joint or the slip joint could be hydraulically or pneumatically energized. Once both packing elements are set, the wellbore may then be treated by flowing fluid out of a ported sub positioned between the packing elements.Type: GrantFiled: May 21, 2015Date of Patent: February 28, 2017Assignee: BAKER HUGHES INCORPORATEDInventors: Juan Carlos Flores, Robert McKitrick

Patent number: 9494010Abstract: A downhole tool having a first packing element and a second packing element configured to synchronically set to selectively hydraulically isolate a portion of the wellbore. The movement of a pin along a j-slot track on a second sleeve sets the second packer in compression and the movement of a pin along a j-slot track on a first sleeve the first packer in tension after the second packer has been set. The j-slot track on the first sleeve has six different pin positions and the j-slot track on the second sleeve has four different pin positions. The pin positions and direction of travel of the j-slot tracks are adapted to permit the synchronized setting of the two packing elements to hydraulically isolate a portion of the wellbore. The wellbore may then be treated by flowing fluid out of a ported sub positioned between the packing elements.Type: GrantFiled: June 30, 2014Date of Patent: November 15, 2016Assignee: BAKER HUGHES INCORPORATEDInventor: Juan Carlos Flores

Publication number: 20160145963Abstract: A packer having a thermal memory spacing system that includes a portion of the system that that selectively changes an outer diameter due. The packer may include upper and lower sealing elements, and at least one thermal memory shape material sub positioned between the sealing elements. The thermal memory shape material sub may have a first outer diameter at a first temperature and a second larger outer diameter at a second temperature. The first temperature may be greater than the second temperature. The outer diameter of the sub may be selectively increased to temporarily decrease the annular area in which debris and/or materials may collect and potentially cause the packer to become stuck within the wellbore. Prior to moving the packer to a different location, the outer diameter of the sub may be decreased to increase the annular area potentially decreasing the likelihood that the packer becomes stuck.Type: ApplicationFiled: November 25, 2014Publication date: May 26, 2016Inventors: Juan Carlos Flores, Rostyslav Dolog

Publication number: 20150361774Abstract: A perforating system for creating perforations that azimuthally circumscribe an inner wall of a wellbore, and that are at substantially the same depth in the wellbore. The perforating system includes perforating assemblies that are housed in a gun body and spaced axially apart. The perforating assemblies have shaped charges positioned at selective angles around an axis of the gun body and at substantially the same axial location in the gun body. Bulkheads are provided between adjacent shaped charges, so that initiating the shaped charges forms angularly spaced apart perforations in a tubular in which the perforating system is inserted.
