The WEI MPD System

is an innovative system that controls and manages the gap of the three-fase flow range (solid-liquid-gas).

The system is composed by

• static density measurement in the mud tank,
• one venture type gauge ,
• one gas flowmeter at the well inlet.

At the well outlet, the system provides a dynamic density measurement, one dynamic measurement Venturi type and one back up pressure control at the borehole choke.
The system also checks well “high pressure” and “gas detection” from the well.
The measurement are skid mounted and they are easily bypassed by gate valves.
All the system is remote controlled by an ATEX PC panel on the drill floor or positioned at Client choice.
The PC analised all signals received and suggests the driller to evaluate actions in case of Kick, Loss or abnormal pressure inside the well. (The maximum tolerated kick or loss value during drilling phase is selectable by a driller during the installation of the software.)
System is completely ATEX and the choke is electrically moved whereas the emergency control is manual.
MPD operates from 800 l/min to 4.500 l/min.
The inlet measurements are API 10K WP, the outlet measurement are 5K WP.
