Introduced in 1951, the M-I SWACO

D-GASSER* has performed reliably

on over 200,000 wells and earnedits reputation as the standard of the

industry. All M-I SWACO D-GASSER

units are designed to remove virtu-

ally all entrained gases, including H2S

and corrosive oxygen, from drillingmud. This reduces the threat of dan-

gerous and costly blowouts caused

by recirculating gas-cut mud.

With its smaller footprint, 42 x

60.7 in. (1,066.8 x 1,541.8 mm),the vertical model is ideal for

confined-space applications.

Features and Benefits Skid-mounted. Simplifies spotting

and installation. Self-contained. The unit consists

of a cylindrical vacuum tank withinternal baffle system, vacuumpump, jet nozzle and three-wayfloat valve.

Three-way float valve. Uniquedesign allows venting to the flareline during H2S service.

Simple operation. The return-flow, gas-cut mud is drawn intothe tank through a vacuum

created by the discharge jet and

pump. The mud is then dispersedin a thin layer over a two-tier,baffle-plate system where theentrained gas, including H2S andcorrosive oxygen, is recovered bythe vacuum pump. The freed gas isthen discharged at a safe distancefrom the drilling operation whilethe restored mud is returned to theactive mud system.

Few moving parts. The D-GASSERunit features only three movingparts: the float inside the vacuum

vessel, the vacuum breaker valve,

and the vacuum pump. The floatensures that the system maintainsthe desired mud-fill level withinthe vessel during operation.

High performance. An M-I SWACOD-GASSER can handle up to 1,000GPM (3,785.4 L/min) while restor-ing mud to its original density.

Built rugged. The unit is ruggedlybuilt and coated inside and outwith corrosion-resistant epoxyto ensure long life and mini-mum maintenance.
