Patent number: 10358892Abstract: Salt or acid solution is stored inside a frac sleeve instead of being pumped from a surface location. A mechanically-actuated valve releases the stored salt or acid solution into the borehole to electrochemically degrade the frac ball and allow it to pass through the seat. The stored fluid can be immediately released upon mechanical actuation or released after a specified delay using an integrated timer. In multiple sleeve applications a first ball shifts a first sleeve to open treatment ports and a second ball shifts a second sleeve to close the treatment port and open screened production ports while releasing the stored material either between the seated objects or above one of the seated objects to initiate the disintegration that will allow objects on both seats to disintegrate and pass through.Type: GrantFiled: July 25, 2017Date of Patent: July 23, 2019Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: John K. Wakefield, Zachary S. Leonard, Colin P. Andrew, Matthew Stone

Patent number: 10215019Abstract: A method of completing a wellbore system that includes a main wellbore and a lateral wellbore intersecting the main wellbore at a junction is disclosed, wherein in one embodiment the method includes placing a first outer assembly below the junction in the main wellbore and placing a second outer assembly below the junction in the lateral wellbore; placing a first inner assembly in the second outer assembly with a top end thereof below the junction, the top end of the first inner assembly including a first wet connect associated with at least one link in the first inner assembly; and connecting a second wet connect of a string with the first wet connect with a top end of the string having a third wet connect corresponding to the at least one link above the junction in the main wellbore.Type: GrantFiled: April 4, 2016Date of Patent: February 26, 2019Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Carl S. Martin, Colin P. Andrew, Michael H. Johnson, Joshua J. Kaufman, Luis E. Mendez, David E. Schneider, Bryan P. Pendleton

Patent number: 9915126Abstract: A dual barrier system withstands pressure differentials well above those of the check valves in a float shoe used to allow circulation of a bottom hole assembly on the way to a desired depth. The bottom hole assembly can have screens and an internal wash pipe that pushes a sleeve to hold open a lower flapper for running in. The wash pipe also holds open an upper flapper that has opposed orientation to facilitate circulation when running in. Once on location an annulus packer closes off the producing zones where the screens are located from a lower zone that can have higher pressures. A high pressure packer is set against the shoe track and the wash pipe is retracted through this packer. Retracting the wash pipe allows closure of both flappers. Flow is blocked in opposed directions by the flappers and packer in the shoe track.Type: GrantFiled: June 9, 2015Date of Patent: March 13, 2018Assignee: Baker Hughes, a GE company, LLCInventors: Colin P.

Publication number: 20170275969Abstract: A ported sub integrates a seat for an object to land on to allow pressure buildup. A sleeve shifts with the ball and the seat to open ports that are screened. The openings feature hardened inserts to control wear from high velocity fluid. The interval is treated through such openings with treatment fluid that is relatively free of solids. The formation is produced through the same screened inserts that were used for treating. The sleeve can be releasably retained in the ports open position and can optionally be closed with well intervention such as with a shifting tool. The object can pass through the seat after sleeve shifting by disintegration or by using a segmented seat that opens enough to allow the object to pass. An array can be spaced throughout the zone for treating or fracturing and the sleeves shifted bottom up using different or same sized balls.Type: ApplicationFiled: March 24, 2016Publication date: September 28, 2017Applicant: BAKER HUGHES INCORPORATEDInventor: Colin P.
