Patent number: 9638681Abstract: Accurate, real-time formation fluids analysis can be accomplished using the systems and techniques described herein. A fluid analyzer includes a first mode of analysis, such as an optical analyzer, configured to determine a physical (optical) property of a fluid sample. The fluid analyzer also includes another mode of analysis, such as a composition analyzer, such as a gas chromatograph, configured to determine a component composition of the fluid sample. A data processor is configured to determine a quantity, such as a weight percentage, of a target component of the fluid sample in response results obtained from the first and second modes of analysis. Beneficially, the results are obtained at least in near real-time, allowing for interim results, such as results from the first analyzer to be used for one or more of tuning the compositional analyzer and for implementing quality control.Type: GrantFiled: September 30, 2011Date of Patent: May 2, 2017Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Oleg Zhdaneev, Christopher Harrison, Youxiang Zuo, Dingan Zhang, William H.

Publication number: 20120125602Abstract: A method of monitoring a nonhydrocarbon and nonaqueous fluid injected into the earth's subsurface through a first wellbore that involves positioning a fluid analysis tool within a second wellbore and determining the presence of the injected nonhydrocarbon and nonaqueous fluid by making a measurement downhole on the injected nonhydrocarbon and nonaqueous fluid using the fluid analysis tool. Also a related method of enhancing hydrocarbon production from a subsurface area having first and second wellbores that involves injecting a nonhydrocarbon and nonaqueous fluid into the subsurface through the first wellbore, positioning a fluid analysis tool within the second wellbore, and determining the presence of the injected nonhydrocarbon and nonaqueous fluid by making a measurement downhole on the injected nonhydrocarbon and nonaqueous fluid using the fluid analysis tool.Type: ApplicationFiled: October 10, 2011Publication date: May 24, 2012Inventors: Francois Dubost, Oliver C.

Publication number: 20110174694Abstract: Kerogen in oil shale is converted to bitumen, oil, gases and coke via a retorting process. The vaporizable oil and gases are then recovered. Following the retorting process, bitumen is recovered via solvent extraction. The overall conversion process is enhanced by calculating conditions to optimize recovery of both oil and bitumen. This can be accomplished by either separately calculating conditions for which production of vaporizable oil and production of bitumen are optimized, or calculating conditions for which production of vaporizable oil and production of bitumen are optimized by applying a maximizing function to combined vaporizable oil and bitumen data. An advantage of this technique is that greater efficiency is achieved because the time duration of heating associated with the retorting process can be reduced and product yields increased.Type: ApplicationFiled: January 15, 2010Publication date: July 21, 2011Applicant: Schlumberger Technology CorporationInventors: Neil Bostrom, Gabriela Leu, Andrew E.

Patent number: 6758090Abstract: The present invention discloses a method and apparatus to detect bubbles in a fluid sample to determine if gases are present, wherein an ultrasonic source is used and its properties monitored. Fluctuations in the ultrasonic source's electrical properties indicate the presence of bubbles/gas. Alternatively, the ultrasonic source may be used to cavitate the sample and induce the nucleation of bubbles. In such a system/method, bubbles may be detected by either (1) monitoring the ultrasonic source properties, (2) monitoring the compressibility of the sample, (3) monitoring the sample properties, including harmonics and subharmonics. The method and apparatus disclosed herein may be used in a borehole such as with a sampling means (including either a flowing sample or a stationary sample) or in a surface lab.Type: GrantFiled: July 26, 2002Date of Patent: July 6, 2004Assignee: Schlumberger Technology CorporationInventors: Neil Bostrom, Douglas D.
