Patent number: 8584749Abstract: Methods for hydrocarbon recovery from a subsurface formation include removing a mixture comprising hydrocarbons and particulate solids from a first formation. At least a portion of the hydrocarbons are separated from the particulate solids. The particulate solids are separated into a plurality of streams. A mixed slurry comprising a first portion of the plurality of streams is injected through a first pipe into the first formation. A waste stream comprising a second portion of the plurality of streams is injected through a second pipe into a second formation. The first formation and the second formation lie in a substantially vertical line.Type: GrantFiled: November 4, 2011Date of Patent: November 19, 2013Assignee: ExxonMobil Upstream Research CompanyInventors: Andrey A. Troshko, Sergio A. Leonardi, David P. Yale

Patent number: 8573301Abstract: An improved method and apparatus for dropping a ball, plug or dart during oil and gas well operations (e.g., cementing operations) employs a specially configured valving member with curved and flat portions that alternatively direct fluid flow through a bore or opening in the valving member via an inner channel or around the periphery of the valving member in an outer channel. In one embodiment, the ball(s), dart(s) or plug(s) are contained in a sliding sleeve that shifts position responsive to valve rotation.Type: GrantFiled: July 10, 2012Date of Patent: November 5, 2013Assignee: Gulfstream Services, Inc.Inventor: Phil Barbee

Patent number: 8567488Abstract: The present invention relates in general to equipment for servicing subterranean wells and in particular to a cementing head that is intended to drop a combination of darts, balls, bombs and canisters in order to activate downhole equipment, launch cementing plugs, deliver chemical products, or the like. A cementing head comprises a modular valve apparatus, comprising at least two detatchable parts. This arrangement allows the operator to remove and disassemble the valve apparatus at the wellsite. Thus, repairs and maintenance may be performed at the wellsite and the valve apparatus may be reassembled and reinstalled, obviating the need to transport the equipment to a central facility.Type: GrantFiled: October 21, 2010Date of Patent: October 29, 2013Assignee: Schlumberger Technology CorporationInventors: Philippe Gambier, Andre Salvaire, Greg Giem, Joel Rondeau

Patent number: 8561700Abstract: An improved method and apparatus for dropping a ball, plug or dart during oil and gas well operations (e.g., cementing operations) employs a specially configured valving member with curved and flat portions that alternatively direct fluid flow through a bore or opening in the valving member via an inner channel or around the periphery of the valving member in an outer channel. In one embodiment, the ball(s), dart(s) or plug(s) are contained in a sliding sleeve that shifts position responsive to valve rotation. An optional indicator indicates to a user or operator that a ball or plug has passed a selected one of the valving members.Type: GrantFiled: May 21, 2010Date of Patent: October 22, 2013Inventor: John Phillip Barbee, Jr.

Patent number: 8561684Abstract: An apparatus for holding and launching down-hole actuation devices that has a body, a bottom end, a top end and a long bore between the ends. Moveable and protruding into the long bore are retainers upon which down-hole actuation devices may rest. Retainers are moved by a lockable hydraulic drive system. Additionally, a method for loading the apparatus with down-hole actuation devices and for launching said devices into a well bore is provided.Type: GrantFiled: August 20, 2012Date of Patent: October 22, 2013Assignee: Stream-Flo Industries Ltd.Inventor: Colin David Winzer
