Patent number: 11624279Abstract: A method comprises flowing a mud into a wellbore, wherein the mud has a mud composition and has a weight in a defined range. The method includes introducing a fluid pill into the mud flowing into the wellbore, wherein the fluid pill has an injection fluid with an injection composition that is different from the mud composition. A particulate has been added to the injection fluid to increase the weight of the fluid pill. After flowing the mud into the wellbore such that the fluid pill is positioned in a zone of the wellbore: filtering out the particulate from the injection fluid; injecting, after the filtering, the injection fluid into the zone; measuring a downhole parameter that changes in response to injecting the injection fluid into the zone; and determining a property of the formation of the zone based on the measured downhole parameter.Type: GrantFiled: September 14, 2021Date of Patent: April 11, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Marcus Ray Hudson, Pramod Chamarthy, Michel Joseph LeBlanc, Christopher Michael Jones, Darren George Gascooke, Anthony Herman van Zuilekom, Jay Paul Deville, William W.

Patent number: 8542955Abstract: A gas detection system is provided for identifying a gas. The gas detection system includes a sensing module with a hollow chamber enclosed by a chamber housing. Additionally, the sensing module includes an optical sensing fiber positioned within the hollow chamber. The optical sensing fiber includes a gas sensor including a fiber Bragg grating positioned at a grating location along the optical sensing fiber, and a sensing layer affixed to an exterior surface of the optical sensing fiber at the grating location. After the gas is directed into the hollow chamber, the sensing layer and the gas exchange heat energy, based in part on a heat transfer coefficient of the gas. The exchange of the heat energy induces a shift in a Bragg resonant wavelength of the fiber Bragg grating which exceeds a threshold shift required for detection, where the shift is used to identify the gas.Type: GrantFiled: October 28, 2010Date of Patent: September 24, 2013Assignee: General Electric CompanyInventors: Hua Xia, Renato Guida, Juntao Wu, Axel Busboom, Aniceto Bantug, Pramod Chamarthy
