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.

A sensor apparatus for wellbore applications includes an electrical conductor extending within an armored tubular jacket to protect the electrical conductor. The electrical conductor is isolated from wellbore fluids when the sensor is placed in a wellhead flange by redundant seals such that the tubular jacket around the conductor does not provide a leak path to the surrounding subsea or surface environment. To isolate the electrical conductor, a connector housing may be provided that establishes a glass-metal seal or a PEEK-metal seal with the electrical conductor. The connector housing may be welded or otherwise sealed to a Christmas tree flange that connects to the wellhead flange. The welds and seals of the sensor apparatus may be proof tested to ensure their effectiveness before the Christmas tree flange is installed in the subsea or surface environment.

A technique facilitates detection of gaseous emissions in a marine environment via a vessel or vessels traversing a region of the marine environment. Environmental data is collected via a detection system on each vessel and communicated to a processing system. The processing system processes various environmental data such as location data, emission detection data, wind data, and/or other data to determine an emissions result. This emissions result is output in a form to facilitate decision-making with respect to potential corrective actions to reduce the gaseous emissions.
