Paper Number: SPE-200513-MS
... bubble remained almost constant. MPD is an adaptive drilling process used to precisely control the annular pressure profile throughout the wellbore ( Kuroda et al., 2017 ). It aims to ascertain the downhole pressure environments and to manage the annular hydraulic pressure profile accordingly. There...

... multivariable control are applied to the drilling process. These methods are based on identification of coupling and interaction between system input (controllable variables), e.g. pump rates and choke valve settings, and output (measured or estimated variables), e.g. pressure at given depths. It is shown how...

... the drilling fluid leak-off and fines migration into the formation. The main targets of this paper are to present the development of a methodology to simulate the gas inflow during UBD processes. The prediction of the inflow during the drilling process is important in order to maintain continuous UBD...
