Characterization of Wear and Dynamic Performance of Interstage Seals for Electric Submersible Pumps (2019-02-22)Electric Submersible Pumps (ESPs) increase head of process fluid in oil production from within the well. An ESP comprises of a pump, seal, and motor section oriented vertically. The pump section includes multiple centrifugal ...

(2009-05-15)This research studies individual and combined effects of hydrogen gas exposure and low temperature on the tribological characteristics of Ti-6Al-4V. Experimental approaches include test system modification and tribological ...
-
(2018-12-04)The scarcity of conventional oil reservoirs has led the oil and gas (O&G) industry to develop non-conventional extraction techniques such as extended-reach drilling (ERD) that brings new engineering challenges. Challenges ...
