Artificial lift
To overcome operational constraints tied to ball-and-seat valves, an operator tested a spring-loaded alternative downhole.
Field results highlight how rethinking tubing-anchor-catcher design can reduce gas interference and support late-life production.
Experience in subsurface production and lift design is shaping a new generation of geothermal operations built for reliability and scalability.
