Patent number: 10392900Abstract: A technique facilitates mechanical operation of components, e.g. valves, without utilizing electronics at the components or control lines routed to the components. An actuation control system is fully mechanical in the sense that it is constructed to mechanically shift to different control positions via pressure input, such as pressure input supplied along a wellbore annulus. The actuation control system utilizes a spool valve coupled with a pilot control circuit which establishes a reference pressure that can be used in shifting the spool valve to different operational positions.Type: GrantFiled: June 29, 2015Date of Patent: August 27, 2019Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Gary Rytlewski, Colin Arthur Longfield, James G.

Patent number: 10371860Abstract: Systems and methods configured to create contour maps of geospatial variables based on hydrometeorological data associated with the variable are described herein. The systems and methods advantageously use simultaneous multi-event universal kriging for spatio-temporal data exploration, analysis and interpolation with the objective of creating a series of related maps, where each map corresponds to a specific sampling event, but wherein some features exhibit spatial relationships persisting over time. In one particular example, water level maps are prepared using the methods, which has the flexibility to allow the conditioning of trend coefficients based on any arbitrary subsets of sample data, and thereby provides a physically based and deterministic rather than wholly-stochastic basis for depicting hydrometeorological data correlations in space and time.Type: GrantFiled: May 22, 2014Date of Patent: August 6, 2019Assignee: S.S.

Patent number: 10352162Abstract: Methods and systems for generating and utilizing a proxy model that generates a pumping parameter as a function of contamination. The pumping parameter is descriptive of a pumpout time or volume of fluid to be obtained from a formation by a downhole sampling tool positioned in a wellbore extending into the formation. The contamination is a percentage of the fluid obtained by the downhole sampling tool that is not native to the formation. The proxy model is based on a true model that utilizes true model input parameters that include the pumping parameter, formation parameters descriptive of the formation, and a filtrate parameter descriptive of a drilling fluid utilized to form the wellbore. The output of the true model is the contamination as a function of the pumping parameter. The proxy model utilizes proxy model input parameters each related to one or more of the true model input parameters.Type: GrantFiled: January 25, 2016Date of Patent: July 16, 2019Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Morten Kristensen, Cosan Ayan, Ryan Sangjun Lee, Nikita Chugunov

Patent number: 9938789Abstract: A ball is retained behind a circular array of collet fingers to be pushed out through the collets with a spring biased piston that is initially locked when run in the hole. The lock mechanism is a link that holds a potential force in the main spring. One end of the link is held by an acceleration or deceleration responsive retainer. The retainer has a conforming stop surface to a stop surface on the link. Sudden relative movement caused by acceleration of the housing allows the retainer that is flanked by opposed springs to move away from the stop surface or surfaces on the link. The link is an array of spaced fingers that can radially flex. The radial flexing combines with the power of the main spring to propel the piston against the ball for a release of the ball. A fracturing operation then ensues.Type: GrantFiled: April 23, 2015Date of Patent: April 10, 2018Assignee: Baker Hughes, a GE company, LLCInventors: Zachary S. Silva, William B. Handy

Patent number: 9388669Abstract: Methods of actuating a well tool can include releasing chemical energy from at least one portion of a reactive material, thermally expanding a substance in response to the released chemical energy, and applying pressure to a piston as a result of thermally expanding the substance, thereby actuating the well tool, with these steps being repeated for each of multiple actuations of the well tool. A well tool actuator can include a substance contained in a chamber, one or more portions of a reactive material from which chemical energy is released, and a piston to which pressure is applied due to thermal expansion of the substance in response to each release of chemical energy. A well tool actuator which can be actuated multiple times may include multiple portions of a gas generating reactive material, and a piston to which pressure is applied due to generation of the gas.Type: GrantFiled: November 20, 2014Date of Patent: July 12, 2016Assignee: Halliburton Energy Services, Inc.Inventors: Adam D. Wright, Michael L. Fripp, Donald G. Kyle, Cyrus A. Irani

Patent number: 9322267Abstract: A downhole compressible fluid sampling tool includes a primary fluid flow line deployed between a fluid inlet probe and a fluid outlet line. A fluid analysis module and a fluid pumping module are deployed in the primary fluid flow line. The fluid pumping module includes a pump in parallel with a bypass flow line having a bypass valve. A compressible fluid sampling vessel is deployed in parallel with and in fluid communication with the primary flow line. A method for obtaining a sample of a compressible downhole fluid includes turning off the pump and opening the bypass valve to enable the downhole fluid to flow into the fluid sampling vessel. The pump may then be optionally turned back on to pressurize the sample.Type: GrantFiled: March 13, 2013Date of Patent: April 26, 2016Assignee: Schlumberger Technology CorporationInventors: Julian Pop, Pierre Henri Campanac

Patent number: 9309745Abstract: A technique facilitates actuation of a downhole tool, such as a valve, in a simple, rapid, and cost-effective manner. The technique comprises installing the downhole tool with a trip saver. The trip saver can be actuated by increasing a tubing pressure or other suitable pressure source beyond a threshold level. Once the trip saver is actuated, a fluid under suitable pressure is provided to a downhole tool through a passageway opened via the trip saver. This enables actuation of the downhole tool to a desired state.Type: GrantFiled: November 8, 2011Date of Patent: April 12, 2016Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventor: Dinesh R. Patel

Patent number: 9228421Abstract: An insert for perforating a subterranean formation sealingly engages a port in a production casing run into a wellbore intersecting the formation. The insert has a core where in a first mode it prevents fluid passage through the insert, and a second mode where the core disengages from the insert upon a treatment fluid reaching a threshold pressure in the casing, and ejects from the insert as a projectile to initiate and contribute to the fracture and stimulation of the formation by the pressurized treatment fluid exiting the port. The insert has a chamber which is filled with a gel that prevents wellbore cement from setting and is covered by a perforated debris shield that permits the equalization of pressure between the chamber and the annulus between the casing and wellbore.Type: GrantFiled: July 30, 2012Date of Patent: January 5, 2016Assignee: Ten K Energy Services Ltd.Inventors: Michael Kent, David Donnelly
