Installation of mud gas separator

Mud gas separators should be installed in the first compartment of the mud tank, downstream of the sand trap or settling tank. The separator should be a minimum of 1.6ft from the tank walls and away from compartment corners to allow for dispersion of solids away the bottom of the separator. The tank compartment should be outfitted with a dump gate to facilitate solids removal and ensure the separator underflow is clear.

Installation of mud gas separator

Mud gas separator inlet line and vent line must be adequately supported and anchored to the tank to restrict movement during well control operations. Additionally, the unit should be removal for servicing.

The vent line should be sloped down toward the flare pit to prevent liquid traps and allow continuous liquid drainage preventing freezing.

When drilling sour or deep horizons, an additional may be installed to increase, operational flexibility. The additional separator may be installed in the active system or in a holding tank remote fronm the rig. In an elevated tank to allow gravity flow of drilling fluid back to the active system. In addition to the gravity return line, a pump may be utilized. In either case, the equipment must be capable of returning mud to the active system without overflows or plugging occurring.
