Patent number: 11028690Abstract: A technique facilitates detection and analysis of constituents, e.g. chemicals, which may be found in formation fluids and/or other types of fluids. The technique comprises intermittently introducing a first fluid and a second fluid into a channel in a manner which forms slugs of the first fluid separated by the second fluid. The intermittent fluids are flowed through the channel to create a mixing action which mixes the fluid in the slugs. The mixing increases the exchange, e.g. transfer, of the chemical constituent between the second fluid and the first fluid. The exchange aids in sensing an amount of the chemical or chemicals for analysis. In many applications, the intermittent introduction, mixing, and measuring can be performed in a subterranean environment.Type: GrantFiled: July 9, 2018Date of Patent: June 8, 2021Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Farshid Mostowfi, Ronald E. G. van Hal, Shahnawaz Hossain Molla, Jane T. Lam, Amy Du, Neil William Bostrom, Michael Mallari Toribio

Patent number: 9891206Abstract: A method for determining scaling cation concentration may include introducing a first solution that includes a scaling cation, incrementally adding a portion of the first solution to a volume of a second solution comprising a counter scaling anion and a complexing agent, wherein the second solution comprises a fixed concentration of the counter scaling anion and the agent, to form a mixed solution, adding the first solution to the second solution until a precipitate of the scaling cation and the counter scaling anion forms, and determining the scaling cation concentration of the first solution.Type: GrantFiled: January 10, 2014Date of Patent: February 13, 2018Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Ronald E.

Patent number: 8826981Abstract: Described herein are variable-volume reservoir (e.g., syringe pump) based processes and systems usable to characterize samples of reservoir fluids, without having to first transport the fluids to the surface. Variable-volume reservoirs are used, for example, for one or more of storing reactants, controlling mixing ratios and storing used chemicals. The processes and systems can be used in various modes, such as continuous mixing mode, flow injection analysis, and titrations. A fluid interrogator, such as a spectrometer, can be used to detect a change in a physical property of the mixture, which is indicative of an analyte within the mixture. In at least some embodiments, a concentration of the analyte solution can be determined from the detected physical property.Type: GrantFiled: September 28, 2011Date of Patent: September 9, 2014Assignee: Schlumberger Technology CorporationInventors: Ronald E.

Patent number: 8708049Abstract: Methods and devices for mixing a first fluid with a second fluid downhole include a chamber having a first end, a second end and an opening for fluid to flow there through. A top surface of a perforated piston is capable of contacting the second end and a top surface of a piston is capable of contacting a bottom surface of the perforated piston. The perforated piston is located at a first position within the chamber based upon characteristics of a first fluid. A first fluid delivery system supplies the first fluid and a second fluid delivery system supplies a second fluid to the chamber, wherein the second fluid is at a pressure that moves the piston approximate to the first end. An actuating device applies a force against the bottom surface of the piston to inject the fluids through channels of the perforated piston to produce spray droplets.Type: GrantFiled: April 29, 2011Date of Patent: April 29, 2014Assignee: Schlumberger Technology CorporationInventors: Jimmy Lawrence, Douglas Grant, Jane T.

Publication number: 20120276648Abstract: Methods and related apparatuses and mixtures are described for spectroscopic detection of hydrogen sulfide in a fluid, for example a formation fluid downhole. A reagent mixture is combined with the fluid. The reagent mixture includes metal ions for reacting with hydrogen sulfide forming a metal sulfide, and a solvent that stabilizes the metal sulfide nanoparticles and assist in preventing precipitation by electrostatic stabilization. The solvent includes a property having a density above 1 kg/l. Further, dissolving the metal ions into the solvent to create the reagent mixture, and mixing the reagent mixture with the hydrogen sulfide sample in a formation. So, the metal ions of the reagent mixture react with the hydrogen sulfide sample to form the metal sulfide nanoparticles, resulting in the metal sulfide nanoparticles having properties with a density from 1 kg/l to about 8 kg/l.Type: ApplicationFiled: April 29, 2011Publication date: November 1, 2012Applicant: Schlumberger Technology CorporationInventors: Ronald E.G. van Hal, Jimmy Lawrence, Jane T.
