    Abstract: The estimation of equivalent circulation density (ECD) in oil well drilling and completion is rather of crucial importance and much care must be given in its calculation. This is because ECD being so sensitive, errors in its value estimation could lead to severe drilling and completion problems like kicks, loss circulation etc. especially when dril... Show More
