Patent number: 9828829Abstract: A completion system includes a lower completion installed in a borehole proximate to a downhole formation. An intermediate completion assembly is included directly engaged with the lower completion. The intermediate completion assembly includes a barrier valve and packer device. The barrier valve is operatively arranged to selectively impede fluid flow through the lower completion and the packer device operatively arranged for isolating the formation. An upper completion string is included that is selectably engagable with the intermediate completion assembly. The barrier valve is operatively arranged to be transitionable to an open position when engaged with the upper completion string and transitions to a closed position via the upper completion string when the upper completion string is pulled out of the borehole. A method of completing a borehole is also included.Type: GrantFiled: March 29, 2012Date of Patent: November 28, 2017Assignee: BAKER HUGHES, a GE company, LLCInventors: Raymond A. Frisby, Jeffrey S. Phillips, Roy N. Nelson, Donald Lauderdale

Patent number: 9027651Abstract: A completion system, including a barrier valve transitionable between an open position and a closed position. An upper completion is operatively coupled with the barrier valve for mechanically transitioning the barrier valve to the closed position when the upper completion is withdrawn. A method of operating a completion system is also included.Type: GrantFiled: March 29, 2012Date of Patent: May 12, 2015Assignee: Baker Hughes IncorporatedInventors: Raymond A. Frisby, Jeffrey S. Phillips, Roy N. Nelson, Donald Lauderdale

Patent number: 9016389Abstract: A retrofit assembly for functionally replacing a fluid isolation valve disposed in a borehole above a lower completion, including a barrier valve operatively arranged to selectively isolate the lower completion when the fluid isolation valve is open. The barrier valve is transitionable between an open position and a closed position due to engagement with an upper completion string. A packer device is included and operatively arranged to isolate a formation in which the borehole is formed.Type: GrantFiled: March 29, 2012Date of Patent: April 28, 2015Assignee: Baker Hughes IncorporatedInventors: Raymond A. Frisby, Jeffrey S. Phillips, Roy N. Nelson, Donald Lauderdale

Patent number: 9016372Abstract: A completion system for arrangement in a borehole including a lower completion, an upper completion string, and an intermediate assembly engaged between the lower completion and the upper completion string. The intermediate assembly includes a single barrier valve only. The barrier valve is operatively arranged to be transitionable to an open position when engaged with the upper completion string and transitions to a closed position via the upper completion string when the upper completion string is pulled out of the borehole.Type: GrantFiled: March 29, 2012Date of Patent: April 28, 2015Assignee: Baker Hughes IncorporatedInventors: Raymond A.

Publication number: 20130255961Abstract: A completion system, including a lower completion initially fluidly open. A production string is included having a removable plug configured to impede fluid flow through the production string. The removable plug is run in with the production string. An intermediate completion assembly is included that couples the lower completion to the production string. The intermediate completion assembly has a packer device and a barrier valve. The packer device is operatively arranged to be set by pressurizing fluid in the production string against the removable plug. The barrier valve is operatively arranged for selectively impeding fluid flow between the production string and the lower completion after the removable plug is removed. A method of completing a borehole is also included.Type: ApplicationFiled: March 29, 2012Publication date: October 3, 2013Applicant: BAKER HUGHES INCORPORATEDInventors: Raymond A. Frisby, Jeffrey S.

Publication number: 20130075109Abstract: A completion system including a barrier valve operatively arranged in a tubing string to selectively impede fluid flow through a lower completion. At least one control line is included for supplying a control line pressure for controlling operation of the barrier valve. The at least one control line is operatively arranged with the tubing string for enabling tubing pressure in the tubing string to determine the control line pressure. A method of operating a barrier valve is also included.Type: ApplicationFiled: March 29, 2012Publication date: March 28, 2013Applicant: BAKER HUGHES INCORPORATEDInventors: Raymond A.
