Reutilization of Ex-Used ESDV for New Well Connection at Pertamina Hulu Mahakam

This page will discuss about the reutilization of Ex-Used ESDV (emergency shut down valve) for new well connection at an Oil and Gas company, namely Pertamina Hulu Mahakam. ESDV has the function to shut-off the flow of fluid from the well head into the pipeline that distributes gas to prevent from pipeline damage. The topic will mainly focus on the reutilization of Ex-Used ESDV from past existing well to be used for future well connection. There are 2 study case, the first one is the fabrication of new coupling part that has the function to connect between the ball valve and actuator of the ESDV. The second study case is the evaluation of reutilized ex-used ESDV compared to new purchase ESDV in terms of cost, time, and quality.
