Publication number: 20130255939Abstract: Methods and apparatus for actuating a downhole tool in wellbore includes acquiring a CCL data set or log from the wellbore that correlates recorded magnetic signals with measured depth, and selects a location within the wellbore for actuation of a wellbore device. The CCL log is then downloaded into an autonomous tool. The tool is programmed to sense collars as a function of time, thereby providing a second CCL log. The autonomous tool also matches sensed collars with physical signature from the first CCL log and then self-actuates the wellbore device at the selected location based upon a correlation of the first and second CCL logs.Type: ApplicationFiled: November 17, 2011Publication date: October 3, 2013Inventors: Krishnan Kumaran, Niranjan A. Subrahmanya, Pavlin B. Entchev, Randy C. Tolman, Renzo Moises Angeles Boza

Publication number: 20130255963Abstract: A technique that is usable with a well includes deploying a plurality of location markers in a passageway of the well and deploying an untethered object in the passageway such that the object travels downhole via the passageway. The technique includes using the untethered object to sense proximity of at least some of the location markers as the object travels downhole, and based on the sensing, selectively expand its size to cause the object to become lodged in the passageway near a predetermined location.Type: ApplicationFiled: May 28, 2013Publication date: October 3, 2013Inventors: Julio C. Guerrero, Gary L. Rytlewski, Bruno Lecerf, Michael J. Bertoja, Christian Ibeagha, Alex Moody-Stuart, Adam Mooney, Jay Russell, Christopher Hopkins, Adam Paxson, Billy Anthony, Dinesh Patel

Patent number: 8544542Abstract: A method and apparatus for controlling the operation of a well which is not flowing or in which fluid is pumped or injected into the well utilising a downhole located pressure monitoring device which is operative to monitor a characteristic pressure profile of the well, and to respond and generate a triggering output when a significant deviation to the pressure profile is introduced into the well as a control signal to the monitoring device by comparing two separate pressure profiles within a certain time span, the device only generating a triggering output when the same pressure profile is monitored twice within the time span; and an actuator which is initiated into operation to control any required operation of the well when the monitoring device responds to the control signal and generates the triggering output.Type: GrantFiled: December 14, 2009Date of Patent: October 1, 2013Assignee: Omega Completion Technology Ltd.Inventors: Mark Buyers, David Forsyth

Patent number: 8540022Abstract: A method for the controlled delivery of a fracturing fluid to a well bore comprises formulating an aqueous base fluid such that it meets or exhibits desired physical and chemical characteristics for an optimal fracturing fluid. The formulation of the aqueous base fluid max involve commingling one or more sources of waste water with a source of fresh water followed by controlled injection of one or more additives. This process is substantially completed prior to delivering the aqueous base fluid to the well site. This allows the delivery of an optimal volume of the aqueous base fluid with homogeneously blended additives to the well bore.Type: GrantFiled: November 27, 2012Date of Patent: September 24, 2013Assignee: Tetra Technologies, Inc.Inventors: Enrico J. Termine, Robert I. Richie

Publication number: 20130240210Abstract: An embodiment of the present techniques provides a method of injecting a particulate mixture into a target location. The method includes forming a mixture of at least two sources of particles with different size distributions wherein the mixture of solids has a permeability in a predefined range. A water content of the mixture is varied to control the rheology of the mixture. The particles are injected through one or more pipes into a target location.Type: ApplicationFiled: September 29, 2011Publication date: September 19, 2013Inventors: David P. Yale, Andrey A. Troshko, Sergio A. Leonardi, Neal L. Adair
