Patent number: 9435180Abstract: A system for producing hydrocarbons may include a production control device positioned along a production flow line. The production control device may include an enclosure having an interior space and an isolation device disposed in the interior space. The isolation device may divide the interior space into an upper interior space and a lower interior space. The production control device may also include a first flow control device positioned in the upper interior space, and a second flow control device positioned in the upper interior space. The first flow control device may be responsive to a control signal transmitted via a control line from a surface location. The second flow control device may reactively block fluid flow from the lower interior section to the upper interior section when a pressure differential between the upper interior space and the lower interior space falls below a preset value.Type: GrantFiled: October 24, 2013Date of Patent: September 6, 2016Assignee: BAKER HUGHES INCORPORATEDInventors: Dario Casciaro, Steven Johnstone

Patent number: 8931570Abstract: An apparatus for controlling fluid in-flow into a wellbore tubular includes a translating flow control element having one or more fluid conveying conduits; and a reactive element that actuates the flow control element. The reactive element may be responsive to a change in composition of the in-flowing fluid. The reactive element may change volume or shape when exposed to or not exposed to a selected fluid. The selected fluid may be oil, water, or some other fluid (e.g., liquid, gas, mixture, etc.). The reactive element may slide the flow control element such that a conduit formed on the flow control element changes length, which then changes a pressure differential across the flow control element.Type: GrantFiled: May 8, 2008Date of Patent: January 13, 2015Assignee: Baker Hughes IncorporatedInventors: Dario Casciaro, Murray K. Howell

Publication number: 20140116688Abstract: A downhole water detection system configured to detect presence of water in an underground location. The system includes a chemical sensor disposable within a tubular in a borehole; and a first water detection body including a first detectable chemical element surrounded by water soluble glass. Wherein the first water detection body is locatable within a fractured formation wherein the chemical sensor is arranged to sense the first detectable chemical element when formation water dissolves the water soluble glass. Also included is a method of detecting water in a formation.Type: ApplicationFiled: January 6, 2014Publication date: May 1, 2014Applicant: BAKER HUGHES INCORPORATEDInventor: Dario Casciaro

Patent number: 8668019Abstract: A plug is disposable in a well bore to block fluid from passing through the wellbore. The plug includes a body formed from water soluble glass. The body is dissolvable in water. A method of utilizing water soluble glass includes employing an element formed of the water soluble glass, performing a first function in the system when the element is present, dissolving the element in the presence of water, and performing a second function in the system different than the first function.Type: GrantFiled: December 29, 2010Date of Patent: March 11, 2014Assignee: Baker Hughes IncorporatedInventor: Dario Casciaro

Publication number: 20100307748Abstract: A control or other line with a hole downhole can be repaired by pumping a device that is driven by pressure delivered behind a leading seal. The device advances until the leading seal passes the opening in the line where its forward movement is stopped. Upstream of the opening a fluid activated seal is energized so that seals now straddle the opening in the wall. A passage that extends between the seals is opened by blowing a rupture disc with internal pressure to once again give access to the downhole tool through the passage that has external seals to straddle the hole in the tubing wall. Normal operation of the downhole tool can then resume.Type: ApplicationFiled: June 9, 2009Publication date: December 9, 2010Inventors: Dario Casciaro, Steve Rosenblatt

Patent number: 7748468Abstract: Sealing devices such as packers comprise a metal foam material disposed on a surface. The metal foam material comprises an initial position comprising a plurality of pockets each having an initial volume and a compressed position in which at least one of the initial volumes of at least one of the plurality of pockets is reduced by compression of the metal foam material, thereby forming a seal. The seal may be formed directly between the metal foam material and a sealing surface such as an inner wall surface of a wellbore to divide an annulus of the wellbore. Alternatively, the seal may be at least partially formed between a sealing material disposed within one or more of the plurality of pockets that is extruded from at least one of the plurality of pockets during compression of the metal foam material.Type: GrantFiled: April 10, 2008Date of Patent: July 6, 2010Assignee: Baker Hughes IncorporatedInventor: Dario Casciaro

Patent number: 7730953Abstract: Systems and methods for selectively operating multiple hydraulic pressure controlled devices (PCDs) within a borehole using a common inflow and outflow line and a common cycling line. A control system is used wherein each of the PCDs is operationally associated with a separate sleeve controller. The sleeve controller for each PCD controls whether the individual PCD can be actuated by hydraulic pressure variations in the common inflow and outflow lines.Type: GrantFiled: February 29, 2008Date of Patent: June 8, 2010Assignee: Baker Hughes IncorporatedInventor: Dario Casciaro

Publication number: 20090188662Abstract: A control system for a subsurface safety valve references the surrounding annulus to put the operating piston in pressure balance. Depending on the configuration and which seal in the system fails, the various embodiments can differ in their failure modes. With the lower end of the piston exposed to annulus pressure all failure modes close the flapper. With the lower end of the piston exposed to tubing pressure, failure of any of the seals except one will result in flapper closure.Type: ApplicationFiled: January 24, 2008Publication date: July 30, 2009Inventors: Dario Casciaro, Ben Lake, Steve Rosenblatt
