Patent number: 7339160Abstract: The invention concerns an apparatus for analysing water chemistry. According to the invention, the apparatus is adapted to operate downhole and comprises a colouring agent supply device for supplying a colouring agent to a water sample, the colour of the water sample thus supplied being indicative of the water sample chemistry, and a colorimetric analyser arranged to determine the colour of the water sample.Type: GrantFiled: November 19, 2003Date of Patent: March 4, 2008Assignee: Schlumberger Technology CorporationInventors: Bhavani Raghuraman, Anthony Robert Holmes Goodwin, Oliver Clinton Mullins, Philip Andrew Rabbito, Li Jiang, Timothy Gareth John Jones, Andrew Loris Kurkjian, Gale Hyslip Gustavson

Patent number: 7062958Abstract: A receptacle (10) for use in collecting samples down a well bore (14) is provided, the receptacle comprising a plurality of interconnecting modules (22, 24, 26, 30, 32, 34). A main chamber (22) is capable of holding a sample, and sensors (58, 60, 62, 64) within the chamber detect physical and chemical characteristics of the sample. Valves (50, 52) in a chamber wall seal the chamber (22) after a fluid sample has been collected. A communication means is placed in communication with the chamber (22) so as to provide an externally accessible port which communicates with the inside of the chamber (22) and allows detection and analysis of sample characteristics without removing the sample from the sealed chamber (22). The chamber (22) includes a piston (82) which is adjustable to keep pressure constant in the chamber and a heating element (58) to keep temperature constant. A method for sampling downhole fluids is also provided.Type: GrantFiled: July 25, 2002Date of Patent: June 20, 2006Assignee: Schlumberger Technology CorporationInventors: Igor Igorevitch Diakonov, Anthony Robert Holmes Goodwin, Andrew Loris Kurkjian, Jonathan Webster Brown, John Allan Nighswander

Patent number: 6988547Abstract: A control system for a hydrocarbon well is also disclosed. A control valve system is used to control the flow of fluid being produced by the well. A real time sensor is provided downhole and is used to make real time measurements of phase characteristics of the fluid. A controller is used to control the valve system so as to reduce the risk of undesirable phase transitions in the fluid based on the real time measurements made by the sensor. The sensor includes an acoustic transducer configured to emit acoustic energy into the fluid at a level which causes a phase transition in the fluid. The controller determines the level of acoustic energy emitted into the fluid, and also determines the pressure associated with a phase transition using the level of emitted acoustic energy.Type: GrantFiled: April 15, 2003Date of Patent: January 24, 2006Assignee: Schlumberger Technology CorporationInventors: Anthony Robert Holmes Goodwin, Kenneth Edward Stephenson, Gary Martin Oddie, Robert Leonard Kleinberg, Douglas D.

Patent number: 6776054Abstract: A method and apparatus is disclosed for determining the flow rates of fluid phases in a pipe containing multiple fluid phases. A Venturi is provided to measure total volumetric flow rate measurement and a holdup measurement is taken approximately 3-10 pipe diameters downstream of the Venturi. The holdup measurement is made at a downstream location where a substantial amount of mixing occurs and the differences between the velocities of the fluid phases can effectively be ignored. The flow rates of the phases can thus be determined directly from the holdup measurements.Type: GrantFiled: February 4, 2002Date of Patent: August 17, 2004Assignee: Schlumberger Technology CorporationInventors: Kenneth Edward Stephenson, John William James Ferguson, John Barry Fitzgerald, Anthony Robert Holmes Goodwin, Gerald Henry Meeten, Sarah Elizabeth Pelham

Patent number: 6755086Abstract: A flow meter for multiphase flows, includes a holdup measuring device having a Venturi located upstream thereof and separated therefrom by a distance that results in flow through the holdup measuring device being at least partially homogenized by the effect of the Venturi on the fluids flowing therethrough.Type: GrantFiled: December 20, 2001Date of Patent: June 29, 2004Assignee: Schlumberger Technology CorporationInventors: Philippe F. Salamitou, Kenneth E. Stephenson, John W. J. Ferguson, John Barry Fitzgerald, Anthony Robert Holmes Goodwin, Gerald H. Meeten, Sarah Pelham

Patent number: 6490916Abstract: A system and method of fluid analysis in a hydrocarbon borehole is disclosed. Acoustic energy is emitted into the production fluid downhole at a level which causes a phase transition in the fluid. The pressure associated with the phase transition is determined using the level of emitted acoustic energy. Advantageously, the determination of the phase transition pressure need not rely on mechanical means to substantially alter the volume of a sample of the fluid. An acoustic transducer can be installed either semi-permanently or permanently downhole in the well. The bubble point or the dew point can be detected. In the case of bubble point detection, the bubbles in the fluid can be detected by sensing variations in impedance of the acoustic transducer, and the level of emitted acoustic energy can determined by measuring the electrical energy used to drive the transducer. A control system for a hydrocarbon well is also disclosed.Type: GrantFiled: December 10, 1999Date of Patent: December 10, 2002Assignee: Schlumberger Technology CorporationInventors: Anthony Robert Holmes Goodwin, Kenneth Edward Stephenson, Gary Martin Oddie, Robert Leonard Kleinberg, Douglas D.
