Patent number: 11585190Abstract: Two control strategies may be implemented to optimize mud circulation in a drilling mud circulation system. In a networked control strategy, the mud circulation system does not involve any centralized controller yet all the local controllers can exchange information in real-time via a central data storage. The master-slave control strategy involves a centralized optimizer, and the subsystems are treated as slave systems and are driven by a visual master control system.Type: GrantFiled: September 17, 2019Date of Patent: February 21, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Jason D.
