Paper presented at the PSIG Annual Meeting, May 7–10, 2024
Paper Number: PSIG-2402
... Abstract Global demand continues for the safe and reliable transport of crude oil. Many midstream energy companies are finding creative solutions to optimize capacity and reduce operating costs of their existing infrastructure in the absence of building new pipelines. As enhancements are made...
