BORETS COMPANY
Gas HandlinG Units
In recent years, the oil industry has shown a tendency towards
complication of well production conditions. It is related to the
transition of main oil fields to the late production stage and
deepening of well production depth. All that results in downhole
temperature rise and solids/GOR increase at the intake of an
electric submersible pump.
Borets offers gas handling units, such as gas handlers,
dispersers and gas separators-dispersers that ensure stable
operation of submersible centrifugal pumps in gassy wells.
Gas Handlers
Gas handlers are designed to ensure stable operation of
submersible cen-trifugal pump with gas cut up to 75%.
Pump gas handlers disperse gas-liquid mixture and compress
associated gas due to a special design of stages only or together
with dispersing unit.
The gas handler can be installed above the gas separator to
address more complicated well conditions (high GOR at the
intake).
Operating components of gas handlers are made of Ni-resist or
powdered materials.

Borets ESP fitted with gas handlers can be used for maximizing
drawdown to enhance production rates, liquid loading gas wells, and
CBM applications.
MNG Series, Rotary and Vortex Gas Separators
Gas separators are designed to provide stable operation of
submersible cen-trifugal pumps with maximum gas cut of 55% at the
intake. For improved gas separation, a tandem gas separator is
available (with two separation chambers). Maximum GOR at the gas
separator intake will be 68%.
Gas separators are based on the following principle: the fluid
entering the gas separator and running into its vanes is separated
into liquid and gas. Separated gas is vented to the annulus and
fluid is directed upwards into the pump.

MND Series Disperser
Maximum GOR at the intake is 55%.Dispersers are designed to
initially reduce the size of the gas bubbles and then change the
distribution of the
gas into a more homogeneous flow regime for the pump.Depending
on the design, disperser can be installed instead of pump intake,
above pump intake or above gas
separator.
MNGD Series Gas Separator-Disperser
Gas separator-disperser is the combination of a gas separator
and disperser which are placed on a common shaft. This combination
allows the electric submersible pump to operate steadily at the
maximum GOR of 68% at the intake.
Formation fluid enters a separation chamber and is separated
into liquid and gas. Separated gas is vented to the annulus, while
remaining oil and gas mixture is directed to the dispersing chamber
and then transformed into a more homogeneous flow regime for the
pump.
The base and protective liner of gas handling units are made of
stainless steel that ensures increased resis-tance to
hydro-abrasive wear. The gas handling units use tungsten carbide
radial bearings. All joints are provided with rubber rings and
fluorpolymer flat gaskets to prevent them from gas leakage and
further breaking.
