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. Steinecker, Gordon R. Lambertus, Neil Bostrom

Patent number: 8968560Abstract: Methods and related apparatuses and mixtures are described for chromatographic analysis. The described system includes a pressurized source of a mobile phase and a flow path in fluid communication with the pressurized source such that the mobile phase flows through the flow path. The system also includes an injector in fluid communication with the flow path and downstream of the pressurized source, the injector being configured to inject a sample into the flow path. A first column located downstream of the injector, contains a stationary phase, and forms part of the flow path. A first detector is positioned to detect properties of fluid in the flow path at a location downstream of the injector and upstream from the first column. A second detector is positioned to detect properties of fluid in the flow path at a location downstream of the first column.Type: GrantFiled: December 6, 2007Date of Patent: March 3, 2015Assignee: Schlumberger Technology CorporationInventor: William H.

Patent number: 8778059Abstract: Methods and related systems are described for improving component separations in chromatography through novel techniques. The improvements in separation is due primarily to the provision of differential acceleration of the components being separated. Various systems and methods for providing differential acceleration are described including: increasing the cross section of the column towards the column outlet, changing the thickness or other composition of stationary phase within the column, and providing a temperature and/or mobile phase velocity gradient along the column.Type: GrantFiled: December 3, 2007Date of Patent: July 15, 2014Assignee: Schlumberger Technology CorporationInventors: William H. Steinecker, Jagdish Shah, Oleg Zhdaneev, Gordon R. Lambertus, Hua Chen

Publication number: 20130206667Abstract: Variable geometry columns for chromatography are disclosed that include a tube having an interior surface and an inlet end and an outlet end, a stationary phase deposited along substantially the length of the interior surface of the tube, and/or deposited on surface area-increasing members positioned within the tube. The resulting column has a gradually enlarging cross-sectional area that is narrower at the inlet end than toward the outlet end attributable to (1) the cross-section of the tube, (2) a variable deposition of the stationary phase, or (3) a combination thereof.Type: ApplicationFiled: January 31, 2013Publication date: August 15, 2013Applicant: NoBull Innovation LLCInventor: William H.

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 chromatographer, configured to determine an elemental composition of the fluid sample.

Patent number: 8377309Abstract: Methods for depositing a stationary phase in a tube for chromatography, in particular, as a variable gradient column are disclosed. The methods include providing a tube having a first end and a second end, the tube containing a fluid composition comprising a stationary phase precursor and a solvent, connecting the first end of the tube to a flow device, removing the solvent from a meniscus of the fluid composition, the solvent exiting the tube at the second end, and operating the flow device while removing the solvent such that the amount of the stationary phase precursor deposited within the tube changes as the meniscus retreats within the tube to deposit a stationary phase having a thickness gradient along the length of the interior of the tube.Type: GrantFiled: November 16, 2010Date of Patent: February 19, 2013Assignee: Nobull Innovation LLCInventor: William H.

Patent number: 8323504Abstract: Methods for depositing a stationary phase in a tube for chromatography, in particular, as a variable gradient column are disclosed. The methods include providing a tube, loading the tube with a concentration gradient of a stationary phase precursor along its length, and removing the solvent such that the stationary phase precursor is deposited within the tube as a stationary phase to form a chromatography column. The concentration gradient is formed by combining at least a first fluid and a second fluid, with the first fluid containing the stationary phase precursor in a solvent.Type: GrantFiled: November 16, 2010Date of Patent: December 4, 2012Assignee: Nobull Innovation LLCInventor: William H.
