Patent number: 11421530Abstract: A fluid sampling probe may include one or more features that increase the likelihood that a seal will be maintained during a sampling operation, even for sampling operations in unconsolidated formations. This may reduce contamination in formation fluid samples that are obtained during sampling operations. The fluid sampling probe may include a reinforcement ring configured to extend into a geological formation beyond an elastomer portion of the fluid sampling probe, which may support the geological formation and prevent a failure of the formation during sampling operations. The fluid sampling probe may also include a stop sleeve to prevent overextension that could otherwise cause the geological formation to collapse. In addition, the fluid sampling probe may include a relatively wider sealing elastomer that may decrease in height monotonically radially from the center of the fluid sampling probe.Type: GrantFiled: May 17, 2018Date of Patent: August 23, 2022Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Stephen Torgerson, Hadrien Dumont, Francois Robert, Christopher Babin, Peter Miller, Tudor Ioan Palaghita, Sebastian Mastrangelo, Gabriel Morosini

Patent number: 11255183Abstract: A method for sampling a downhole formation fluid includes pumping formation fluid into the flowline of a downhole sampling tool While pumping, a saturation pressure of the formation fluid is measured. The pumping rate is adjusted such that the fluid pressure in the flowline remains above a threshold saturation pressure.Type: GrantFiled: July 6, 2020Date of Patent: February 22, 2022Inventors: Kentaro Indo, Julian Pop, Maxim Yushko, Tudor Ioan Palaghita, Zeynep Alpman, Alexis Petit, Sepand Ossia, Tullio Moscato

Patent number: 11021952Abstract: A pressure testing module separable from and configured to be coupled with a tool base that is to be coupled along a downhole tool string to be conveyed within a wellbore extending into a subterranean formation. The pressure testing module includes a chamber and a piston assembly slidably disposed within the chamber, thus dividing the chamber into a first chamber portion and a second chamber portion. The piston assembly is operable to move in response to hydraulic fluid being pumped into the first chamber portion and to draw formation fluid of the wellbore into the second chamber portion in response to the movement of the piston assembly.Type: GrantFiled: July 13, 2020Date of Patent: June 1, 2021Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Arun Sharma, Tudor Ioan Palaghita, Ashers Partouche

Patent number: 10584583Abstract: A method including positioning a downhole acquisition tool in a wellbore in a geological formation; performing a pretest sequence to gather at least one of pressure or mobility information based on downhole acquisition from a sample line, a guard line, or both while the downhole acquisition tool is within the wellbore. The pretest sequence includes controlling a valve assembly to a first valve configuration that may allow the fluid to flow into the downhole tool via one or more flowlines toward a pretest system. The one or more flowlines include the sample line only, the guard line only, or both the sample line and the guard line; and drawing in the fluid through the one or more flowlines. The method also includes controlling the valve assembly to a second valve configuration. The second valve configuration is different from the first valve configuration and may block the one or more flowlines from drawing in the fluid.Type: GrantFiled: June 29, 2017Date of Patent: March 10, 2020Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Adriaan Gisolf, Tudor Ioan Palaghita, Stephen Dennis Parks, Ashers Partouche
