Control of wellbore pressure during drilling operations has always been important in the oil industry as this can prevent the possibility of well blowout. The present research employs a combination of automatic process control and statistical process control for the first time for the identification, monitoring, and control of both random and special causes in drilling operations. To this end, ...

Abstract The objective of this chapter is to introduce the concepts calculated Datapoints and key performance indicators, which form basis statistical process control. In particular, both operate on Datapoints, but them in a different way. Indeed, former transform incoming data static way, i.e., without taking into account its historical values. Contrarily, latter within specified period for fu...
