Patent number: 8770290Abstract: A gravel pack assembly gravel packs a horizontal borehole. Operators wash down the borehole using a tool in a first position by flowing fluid from the tool through the apparatus' toe. Operators then gravel pack by moving the tool to a first flow port between a screen and the toe. Slurry flows into the borehole from the first flow port, and returns from the borehole flow through the screen. The gravel in the slurry can pack the borehole in an alpha-beta wave from toe to heel. When the tool has a sleeve, operators can break any bridges by flowing fluid from the passage of the assembly into the tool. In another condition, operators can move the tool to a second flow port. Slurry can flow into to the borehole through a shunt extending from the second flow port. Meanwhile, returns can flow from the borehole through a bypass in the assembly.Type: GrantFiled: October 28, 2010Date of Patent: July 8, 2014Assignee: Weatherford/Lamb, Inc.Inventors: Ronald van Petegem, John Broussard

Patent number: 8528642Abstract: Described is a well completion for evenly distributing a viscosity reducing injectant (e.g. steam and/or solvent, e.g. in SAGD or CSS) into a hydrocarbon reservoir (e.g. of bitumen), for evenly distributing produced fluids (most specifically vapor influx) and for limiting entry of particulate matter into the well upon production. On injection, the injectant passes through a limited number of slots in a base pipe, is deflected into an annulus between the base pipe and a screen or the like, and passes through the screen into the reservoir. On production, hydrocarbons pass from the reservoir through the screen into a compartmentalized annulus. The screen limits entry of particulate matter (e.g. sand). The hydrocarbons then pass through the slots in the base pipe and into the well. Where a screen is damaged, the compartmentalization and the slots in the base pipe limit particulate matter entry into the well.Type: GrantFiled: May 6, 2011Date of Patent: September 10, 2013Assignee: ExxonMobil Upstream Research CompanyInventor: Thomas J Boone

Patent number: 8528641Abstract: A fracturing and gravel packing tool has features that prevent well swabbing when the tool is picked up with respect to a set isolation packer. An upper or multi-acting circulation valve allows switching between the squeeze and circulation positions without risk of closing the low bottom hole pressure ball valve. The low bottom hole pressure ball valve can only be closed with multiple movements in opposed direction that occur after a predetermined force is held for a finite time to allow movement that arms the low bottom hole pressure ball valve. The multi-acting circulation valve can prevent fluid loss to the formation when being set down with the crossover tool supported or on the reciprocating set down device and the multi-acting circulation valve is closed without risk of closing the wash pipe valve.Type: GrantFiled: September 3, 2009Date of Patent: September 10, 2013Assignee: Baker Hughes IncorporatedInventors: Nicholas J. Clem, Martin P. Coronado, Jeffery D. Kitzman, Jeffry S. Edwards

Patent number: 8517098Abstract: A method, system and apparatus associated with the production of hydrocarbons are described. The method includes disposing a plurality of sand control devices having a primary flow path and a secondary flowpath within a wellbore adjacent to a subsurface reservoir. A packer having primary and secondary flow paths is then coupled between two of the sand control devices such that the primary and secondary flow paths of the packer are in fluid flow communication with the primary and secondary flowpaths of the sand control devices. The packer is then set within an interval, which may be an open-hole section of the wellbore. With the packer set, gravel packing of the sand control devices in different intervals may be performed. The interval above the packer may be packed before the interval below the packer. A treatment fluid may then be injected into the wellbore via the secondary flow paths of the packer and sand control devices.Type: GrantFiled: December 15, 2006Date of Patent: August 27, 2013Assignee: ExxonMobil Upstream Research CompanyInventors: Bruce A.

Publication number: 20130213638Abstract: Methods for heating a material within a wellbore using nano-particles such as carbon nano-tubes. The material may be a flowable material such as cement, drilling mud, an acidizing fluid, or other material. Generally the methods comprise placing the flowable material in proximity to a radial wall of a wellbore. The methods also include running an energy generator into the wellbore. In one aspect, energizing the nano-particles in the filter cake causes the nano-particles to be activated, and increases a temperature within the flowable material to a temperature that is greater than an initial circulation temperature of the flowable material. Activating the energy generator may also assist in curing the flowable material in situ.Type: ApplicationFiled: August 29, 2011Publication date: August 22, 2013Inventors: Stuart R. Keller, Shankar Sundararaman
