Managed pressure drilling manifold and methods

A managed pressure drilling (MPD) manifold has one or more valves that are operable by one or more actuators configured to synchronize the opening of one or more passageways in the valves with the closing of one or more of the other passageways in the valves, in order to minimize the likelihood of error and reduce response time. The valves are configured to transition smoothly between positions without fully blocking fluid flow in the manifold while changing the flow direction. The synchronization may be achieved mechanically, electrically, hydraulic, and/or pneumatically. The actuators may be remotely controlled by a control unit having a processor and control logic software, based on data collected by one or more sensors in the MPD manifold. The positions of the valves of the MPD manifold may be automatically adjusted by the control unit via the actuators.

Measurement data including data of a sand production rate from a sand metering sensor, pressure data from a pressure sensor, and data of a metal loss value from a metal loss sensor is obtained. A maximum sand erosional velocity ratio and a pressure drawdown are determined. An optimum choke valve setting is determined based on a predefined correlation between the sand production rate, the pressure drawdown, and the maximum sand erosional velocity ratio, in response to determining that the maximum sand erosional velocity ratio is not within a predetermined maximum sand erosional velocity ratio limit. An updated pressure drawdown produced by the determined optimum choke valve setting is within a predetermined pressure drawdown operating window. The surface choke valve is set based on the determined optimum choke valve setting. The well is shutdown by triggering an emergency shutdown device in response to determining that the obtained metal loss value has reached a predefined metal loss limit value.
