Patent number: 8517102Abstract: A thickened aqueous composition is delivered to a subterranean location accessible via a wellbore by steps of i. providing a biphasic aqueous mixture comprising two aqueous solutions which, at surface temperature and pressure, are able to co-exist as separate aqueous phases in contact with each other, ii. pumping said biphasic aqueous system down the wellbore to the subterranean location, and iii. converting the biphasic mixture below ground so that its phases combine into a single aqueous phase which is more viscous than the biphasic mixture. The two phases of the aqueous biphasic mixture contain dissolved solutes which segregate between the two phases such that at least one first solute is present at a greater concentration in the first aqueous phase than in the second aqueous phase while at least one second solute is present at a greater concentration in the second aqueous phase than in the first aqueous phase.Type: GrantFiled: November 26, 2008Date of Patent: August 27, 2013Assignee: Schlumberger Technology CorporationInventors: Philip Sullivan, Gary Tustin, Yenny Christanti, Gregory Kubala, Bruno Drochon, Trevor Hughes

Publication number: 20130142763Abstract: Crosslinked cellulosic polymers, crosslinked cellulosic polymer hydro-gels, and methods for their synthesis and use are described. The crosslinked cellulosic polymers include one or more cellulosic polymers and a one or more crosslinkers that crosslinks the one or more cellulosic polymers together. The crosslinking can be facilitated with a crosslinking agent capable of linking with a monomer the cellulosic polymer and crosslinking the cellulosic polymer intermoleculerly and/or intramolecularly. Crosslinked cellulosic polymers are well adapted for use in cell and tissue growth in vivo and in vitro. The crosslinked cellulose polymers may also be used as wound care devices.Type: ApplicationFiled: October 27, 2010Publication date: June 6, 2013Applicant: EMPIRE TECHNOLOGY DEVELOPMENT LLCInventors: William B.

Patent number: 7874362Abstract: Tubewaves are used to transmit an indication of the depth at which a condition is detected in a well. In particular, the depth is calculated based on the difference in arrival time at the surface of a first tubewave which propagates directly upward in the borehole and a second tubewave which initially travels downward and is then reflected upward. The tubewaves may be generated by a canister designed to implode at a certain pressure. The canister is carried downhole by gravity and the fluid being pumped. At a depth at which its pressure tolerance is exceeded, it implodes and generates the tubewaves. An analyzer at the surface detects the tubewaves and generates a pressure versus depth profile of the well. Canisters may be acoustically tagged in order to generate tubewaves having particular frequency and amplitude characteristics. Canisters may also be configured to produce multiple implosions.Type: GrantFiled: March 26, 2007Date of Patent: January 25, 2011Assignee: Schlumberger Technology CorporationInventors: Richard Timothy Coates, Douglas E.

Publication number: 20100184631Abstract: A method of providing a viscous emulsion at a subterranean location accessible via a wellbore, begins by providing an aqueous/aqueous emulsion comprising two aqueous solutions which, at surface temperature and pressure, are able to co-exist as separate aqueous phases in contact with each other. The two phases contain respective solutes which are sufficiently incompatible that they cause phase separation. The dispersed phase is rich in one solute, which may be a thickening polymer, while continuous phase is rich in a second solute, which may comprise surfactant. A hydrophobic liquid is dispersed in this emulsion to become the dispersed phase of a viscous emulsion whose continuous phase is provided by the aqueous/aqueous emulsion. The hydrophobic liquid and the aqueous/aqueous emulsion may be pumped separately down the wellbore to the subterranean location, and allowed to mix there so as to form the viscous emulsion at the subterranean location.Type: ApplicationFiled: January 16, 2009Publication date: July 22, 2010Applicant: Schlumberger Technology CorporationInventors: Mark Turner, Gary John Tustin, Christelle Vatry, Philip Sullivan

Patent number: 7706995Abstract: Systems, methods, and apparatus, including software implementation, are disclosed providing drift prediction of output values for manometers. A signal or other indication may be provided for or in relation to a capacitance manometer when a servicing, replacing, and/or zeroing event is predicted or determined to be required, based on a history (e.g., timestamps) associated with previous zeroing events. Previously recorded timestamps can be curve fit with suitable functions to calculate or predict future maintenance, calibration, and/or replacement events for a manometer. Such signals or indications can be generated as an on-screen indication, and could also be available upon interrogation of the manometer via a digital communications link or system.Type: GrantFiled: April 16, 2007Date of Patent: April 27, 2010Inventors: Philip Sullivan, David Alcaide

Publication number: 20090151938Abstract: A method for preparing a formation surrounding a wellbore to bear hydrocarbons through a borehole is disclosed. In one step, a bottomhole assembly is inserted into the borehole. The formation is drilled with the bottomhole assembly. The formation may be characterized with logging tools, probes, sensors, seismic system and/or the like to create first information. One or more fractures are placed in the formation without removal of the bottomhole assembly from the wellbore. Further, continuous drilling of the formation is performed with the bottomhole assembly after/during placing the fractures. Further characterizing of the formation with the probes, sensors/systems or the like is performed to produce second information. Another fracture is placed with feedback from the second information. Repeating the drilling, characterizing and placing of fractures as necessary during the formation preparing process.Type: ApplicationFiled: December 18, 2007Publication date: June 18, 2009Inventors: Don Conkle, Ashley Johnson, J.

Publication number: 20080236935Abstract: Tubewaves are used to transmit an indication of the depth at which a condition is detected in a well. In particular, the depth is calculated based on the difference in arrival time at the surface of a first tubewave which propagates directly upward in the borehole and a second tubewave which initially travels downward and is then reflected upward. The tubewaves may be generated by a canister designed to implode at a certain pressure. After being introduced into the flowline at an above ground inlet, the canister is carried downhole by gravity and the fluid being pumped. When the canister reaches a depth at which its pressure tolerance is exceeded, it implodes and generates the tubewaves. An analyzer at the surface detects the tubewaves with a hydrophone array and generates a pressure versus depth profile of the well, i.e., one data point for each implosion.Type: ApplicationFiled: March 26, 2007Publication date: October 2, 2008Applicant: Schlumberger Technology CorporationInventors: Richard Timothy Coates, Douglas E.

Publication number: 20080239872Abstract: A predetermined condition in a fluid-filled wellbore system can be detected by generating at least one sound in the wellbore system in response to the condition, such that a detectable change is created in some characteristic of the emitted sound, and detecting the at least one sound and the change, the detection being indicative that the predetermined condition has occurred. Equipment for facilitating detection of the condition can include a trigger operable in response to the condition; a generator operable to emit sound in the borehole and to create a detectable change in some characteristic of the emitted sound in response to the trigger; and at least one sensor operable to monitor the sound and detect the change, the detection being indicative that the predetermined condition has occurred. It is also possible to estimate a value of a property of a fluid-filled wellbore system.Type: ApplicationFiled: March 26, 2007Publication date: October 2, 2008Applicant: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Douglas E.
