摘要: Apparatuses useable in drilling installations for adjusting a mud return flow in a mud loop, at a location far from a mud tank are provided. An apparatus includes (1) a sensor located close to a seabed and configured to acquire values of at least one parameter related to a return mud flow, (2) a valve located near the sensor and configured to regulate the return mud flow, and (3) a controller connected to the valve and the sensor. The controller is configured to automatically control the valve to regulate the return mud flow towards achieving a value of a control parameter close to a predetermined value, based on the values acquired by the sensor. Methods of incorporating an apparatus in a drilling installation and retrofitting existing installations are also provided.
