Publication number: 20180181700Abstract: Techniques for improving implementation of a downhole tool string to be deployed in a borehole formed in a sub-surface formation. In some embodiments, a design device determines a model that describes expected relationship between properties of the downhole tool string, the borehole, the sub-surface formation, and mud cake expected to be formed in the borehole; determines calibration locations along the borehole based on properties of the borehole; determines candidate spacer configurations based on contact force expected to occur at contact points between the downhole tool string and the mud cake when deployed with each of the candidate spacer configuration via the model; and determines a final spacer configuration to be used to attach one or more spacers along the downhole tool string based on expected head tension to move the downhole tool string when deployed in the borehole with each of the candidate spacer configurations via the model.Type: ApplicationFiled: December 28, 2016Publication date: June 28, 2018Inventors: Kai Hsu, Scott C.

Publication number: 20180171790Abstract: 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: ApplicationFiled: December 11, 2017Publication date: June 21, 2018Inventors: Arun Sharma, Tudor loan Palaghita, Ashers Partouche

Publication number: 20180003049Abstract: 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: ApplicationFiled: June 29, 2017Publication date: January 4, 2018Inventors: Adriaan Gisolf, Tudor Ioan Palaghita, Stephen Dennis Parks, Ashers Partouche

Publication number: 20170152743Abstract: A method includes operating a downhole acquisition tool including a guard probe and a sample probe in a wellbore that contains a fluid that includes a native reservoir fluid and a contaminant. The method also includes receiving a first portion of fluid into the guard probe and a second portion of fluid into the sample probe, estimating a contamination level of the first or second portions based on a fluid property of the respective first and second portions, determining an initial guard flow rate of the first portion, determining an initial sample flow rate of the second portion, using a processor to adjust a guard flow rate of the second portion over pump time after the contamination level of the first portion is at or below a contamination level threshold, and adjust a sample flow rate of the first portion based on the adjusted guard flow rate and total flowrate.Type: ApplicationFiled: December 1, 2015Publication date: June 1, 2017Inventors: Adriaan Gisolf, Kai Hsu, Yong Chang, Youxiang Zuo, Ryan Sangjun Lee, Ashers Partouche
