Estimation of Bottomhole Pressure for Managed Pressure Drilling : Comparison of Nonlinear Estimators
To avoid hole stability problems in an increasingly fierce drilling environment, the demand for accurate control of the pressure profile during drilling operations is rising. As standard instrumentation of drilling rigs have poor measurement of the bottom hole pressure, there is a need for estimatio...
