Patent number: 9194217Abstract: A technique facilitates sand control in a wellbore. A lower completion and an upper completion are run downhole into the wellbore and deployed. The lower completion assembly employs a plurality of packers to isolate well zones. The lower completion assembly also has gravel pack ports which are independently opened to enable gravel packing of each individual zone via a tool run downhole. Additionally, the lower completion assembly has a production port in each zone. A shifting tool is employed to open the production ports and to enable production from the well zones.Type: GrantFiled: May 26, 2010Date of Patent: November 24, 2015Assignee: Schlumberger Technology CorporationInventors: Graham Watson, Dinesh Patel, Tom Saunders, Luis Felipe Peixoto, Ricardo Gomez Simancas, Julien Debard

Patent number: 9062530Abstract: A technique includes running a lower completion assembly into a well in a single trip. The lower completion assembly includes a screen, a first valve and a second valve. The technique includes performing a gravel packing operation using the lower completion assembly, where performing the gravel packing operation includes running a service assembly into the lower completion assembly to operate the first valve. The technique further includes removing the service assembly from the well and subsequently installing an upper completion assembly in the well. The installation of the upper completion assembly enables remote control of the second valve of the lower completion assembly for purposes of regulating the production of fluid from the well.Type: GrantFiled: February 7, 2012Date of Patent: June 23, 2015Assignee: Schlumberger Technology CorporationInventors: Dinesh Patel, Andreea Madalina Tatulescu, Bryan Stamm, Spyro Kotsonis, Tom Saunders

Patent number: 8408300Abstract: A stimulation system configured for use in open-hole wells. The system may alternatively or additionally be configured for multi-zone stimulation applications. The system includes assemblies which employ techniques and configurations for isolating recovery screens downhole even without the presence of well casing. In this manner protection may be provided from dowhnole contaminants such as water which might otherwise leak in from adjacent formation layers.Type: GrantFiled: February 15, 2010Date of Patent: April 2, 2013Assignee: Schlumberger Technology CorporationInventors: Ricardo Gomez Simancas, Bryan Stamm, Graham M.

Patent number: 8151883Abstract: A stimulation technique is provided for use in an open hole well. The stimulation technique utilizes a system which comprises one or more isolation devices positioned to isolate desired regions of the open hole well. At least one release mechanism is used to provide controlled release of stimulation material to a desired wellbore region of the open hole well. Additionally, a protection mechanism cooperates with each release mechanism to prevent undesirable contact between stimulation material and the surrounding wellbore wall of the open hole well. In many applications, the entire system is deployed and operated during a single trip downhole into the well.Type: GrantFiled: June 6, 2010Date of Patent: April 10, 2012Assignee: Schlumberger Technology CorporationInventors: Ricardo Gomez Simancas, Bryan Stamm, Graham R.
