Managed Pressure Drilling Manifold and Methods
20230272683 · 2023-08-31 ·

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.

A system and method for carbon capture and storage in a depleted hydrocarbon reservoir or dedicated aquifer is disclosed. A wellhead block includes or supports therewith a barrier subsystem having one or more of at least one isolation gate valve or one or more plugs. The barrier subsystem is to allow access to a well that is associated with the depleted hydrocarbon reservoir or dedicated aquifer. The system includes modulation valves to modulate an injection of a wellhead fluid that includes a carbon component into the wellhead block.

Closed-loop hydraulic drilling

A closed-loop hydraulic drilling system generates choke characteristic curves or data that more accurately reflects the relationship between the commanded choke valve position and the resulting pressure drop across the choke valve for a given flow rate and fluid density. The choke characteristic curves may be generated through a calibration procedure and then used during normal operations to more accurately monitor return flow and manage wellbore pressure. The specific gravity of an injected calibration fluid and pressure drop across the choke valve may be determined and correlated to the current choke valve position to reflect the choke characteristic curve in situ, thereby providing for more precise control of wellbore pressure and enabling condition monitoring of the choke valve. In addition, an improved closed-loop hydraulic drilling system does not require a flow meter, enabling the adoption of MPD systems in low-specification and economically constrained applications.

A choke valve system operable to obtain sand production measurements from a sand production sensor, compare the sand production measurements to a target sand production range for a current setting of a choke valve, and, in response to determining that the sand production measurements are outside of the target sand production range, adjust the setting of the choke valve in an effort to bring the sand production of the well into a target sand production range, and generate an alert regarding the out of range sand production measurements and the corresponding adjustment of the choke valve.

Safe dynamic handover between managed pressure drilling and well control

Safe dynamic handover between MPD and well control operations provides the ability to automate MPD, well control, and transitions therebetween while maintaining the wellbore in a dynamic fluid state at all times. In the event a kick is taken, a safe dynamic handover from MPD to well control operations is made, unknown formation fluids within the wellbore are circulated out of the wellbore, and a safe dynamic handover from well control operations to MPD is made while maintaining the wellbore in dynamic fluid state, without ever going static with respect to fluids within the wellbore. Because the wellbore remains dynamic, the formation of gels is prevented, thereby preventing pressure spikes during the start-up of the mud pumps and improving pressure transmission throughout the well system. Pressure may be more precisely managed during all phases of MPD, well control, and transitions therebetween.
