Analysis of intermittent gas lift systems.

Journal of the Japanese Association for Petroleum Technology, 1989
In the Kubiki oil field, oil is extracted by the intermittent gas lift system. Our concern is to reduce operating cost because of the present low price of oil. So as to optimize the intermittent gas lift system, the time taken to inject gas and the cycle frequency have been determined through trial and error and other means. If production volume can be

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.
