Patent number: 9995698Abstract: Disclosed is a method and system for integrating measurements from known laboratory techniques of fluid extraction (Dean Stark, Retort, Rock-Eval), which conducted independently by multiple disciplines and which have been so far treated as independent evaluations. In using these results, particularly Dean Stark and Retort, the oil industry has shown specific preferences between these two methods, with some groups advocating the validity of one method over the other, and others showing the opposite. Forums and discussions have been organized by the technical community to debate the benefits and drawbacks of each of these and to define which is the more suitable for reservoir characterization. Commercial laboratories have specialized in one method or the other based on their perceived validity. Both methods are correct, but each measure an incomplete assessment of the properties needed, and that together they provide considerable more information than when considered independently.Type: GrantFiled: October 20, 2016Date of Patent: June 12, 2018Assignee: W.D.

The combined mixture and formation fluid is then spectroscopically interrogated so as to detect the presence of the metal sulfide thereby indicating the presence of hydrogen sulfide in the formation fluid. The mixture also includes chelating ligands for sustaining thermal endurance of the mixture under downhole conditions.Type: GrantFiled: October 26, 2007Date of Patent: June 14, 2011Assignee: Schlumberger Technology CorporationInventors: Li Jiang, Oliver C.

Patent number: 7896578Abstract: An apparatus and method for evaluating chemicals of interest in a subsurface bore hole, such as a groundwater sampling well. An absorbent member is attached to a flexible liner, and the liner is everted by fluid pressure down the borehole. The everted liner presses the absorbent member against the wall of the borehole. Any chemicals of interest are absorbed into the absorbent member from the media surrounding the borehole. The liner, with associated absorbent member thereon, is then extracted from the borehole. The absorbent member may then be subjected to any suitable laboratory analysis to evaluate the type, spatial distribution, and concentration of chemicals of interest, such as water contaminants occurring in the borehole.Type: GrantFiled: June 30, 2008Date of Patent: March 1, 2011Inventor: Carl Keller

Patent number: 7807467Abstract: A method is disclosed for predicting the High Frequency Reciprocating Rig (HFRR) wear scar diameter for a hydrocarbon mixture using an HFRR wear scar diameter prediction equation which predicts the HFRR wear scar diameter based on the mid-infrared spectroscopy test results for such hydrocarbon mixture. Such predicted HFRR wear scar diameter value can then be used to determine the necessity of adding a lubricity additive to a diesel material in order to produce a diesel product possessing adequate lubricity properties.Type: GrantFiled: October 17, 2006Date of Patent: October 5, 2010Assignee: ConocoPhillips CompanyInventor: Enrico A.

Publication number: 20100240135Abstract: The invention provides a method of testing sour natural gas by a) removing H2S from the gas stream, b) converting H2S to elemental sulfur, and c) recovering elemental sulfur. The invention also provides a substantially mobile system for testing sour natural gas including vehicles allowing the equipment to be operated on surfaces such as the flat beds of trailers. The system features equipment that may be mounted within one or more support structures situated on a mobile vehicle, such as, for instance the flat bed of a trailer. The one or more support structures hold each piece of equipment substantially fixed in place on the vehicles. Each surface such as the flat bed of a trailer may carry one, two or more pieces of equipment. The equipment may include, for instance, an air or oxygen compressor, a knockout vessel, a gas heater, an air heater, a cooler, a molten sulfur separator and a thermal oxidizer.Type: ApplicationFiled: March 19, 2010Publication date: September 23, 2010Inventors: David M. Seeger, Bonnie S. Davis, Eric C. Klasson, Bryan J. Petrinec
