SUDOS-mini 2 level gauge
SUDOS mini 2 level gauge is designed for realtime
monitoring of the fluid level in oil producing
wells. The level gauge monitors the static and
dynamic level, records level curves,
automatically records gas pressure in the annulus
at thewellhead.
SUDOS-automat 2 level gauge
SUDOS automat 2 level gauge is designed for
automatic control of the fluid level in oil
producing wells. The level gauge monitors the
static and dynamic level, records level curves,
automatically records gas pressure in the annulus
at the wellhead. The tool is extremely useful for
performing automated pressure transient tests or
timeconsuming level monitoring when the well is
out to the operating regime.
SIDDOS-automat dynamometer
SIDDOS automat dynamometer is designed for
complex monitoring of sucker rod pump units with
two clamp bridle. The tool performs automatic
single and repeated recording of load and
position dynamograms while the pump is operating
or being put to the working regime, as well as
monitors leaks during the static state of the
pump using the 'loss line' technique.

Submersible Progressing Cavity Pump
Through Tubing Conveyed Submersible Progressing
Cavity Pump (SPCP) is intended for viscous high
gas factor oil recovery in marginal wells with
minimum internal casing string size of 122 mm.
Pumping unit consists of going-in with
oil-well tubing submersible four-pole electric
motor with power cable, starting clutch, seal
section, base coupling and intake receptacle.
Assembling and disassembling of SPCP is carried
out through oil-well tubing with borehole cable
of geodesic elevator. The SPCP includes two
working screw gages (left and right), gear box
with axial and radial bearings, tubing
anchor/packoff. Rotation is transmitted from gear
box to screw gages via flexshaft.

K O R V E T
KORVET is the most dynamic Russian manufacturer
of Wellheads, X-mas trees, valves, manifolds and
pipeline equipment. KORVET equipment meets API
Spec 6A and 6D requirements and since 1997 has
been produced with API monogram. KORVET is
certified for ISO 90012000 standard.
14
X-MASS TREES
KORVET produces any scheme of tree, resulting of
combining blocks valves, chokes, crosses and so
on. WP is up to 10 000 psi. H2S and CO2
concentration is up to 6.
15
WELLHEADS
KORVET produces wide range of wellhead equipment
for surface applications. Safety requirements,
robustness and cost effectiveness are most
considering goals for KORVET. Rig time savings
were also a strong consideration taken into
account. Certified for API6A.
16
CHECK VALVES
Swing-type and spring-type check valves are
designed to cut off back flow of operating medium
in pipelines. Sealing surfaces are made of
stainless steels. Casted or forged body. Flanged
and weld connections available. WP in range
6-250 bar.
17
BALL VALVES
Ball valves are designed to control pipelines
with natural gas, oil, oil products and other
non-agressive fluids. They are reliable, of
simple design, easy to mount and to operate,
compact and light. The valve design (the body
with seats and a ball is disposed between two
flanges and tightened with studs) ensures
disassembly of the valve without cutting
pipelines. It is very convenient for monitoring
and running repair. Ball valves are available
manually operated, including for underground
application and with electric or pneumatic
actuators.
18
MANIFOLDS
Manifolds are designed for controlling and
distributing gas or fluids flow to collector.
Manifolds are delivered as a set of units such a
valves, fittings, check valves, chokes and so on.
Any unit fulfils some technological operations.
Manifolds and technological equipment are
manufactured according to the requirements of
Elaboration Institute and State Technical
Inspection.

PDN-44-1200 PUMP

• The PDN-44-1200 is a tubing sucker-rod pump with
  plunger-diaphragm chambers designed for pumping
  wellbore fluids containing high amounts of
  mechanical impurities. The PDN-44-1200 is
  patented (PCT numbers WO 99/04166, WO 9915791A1)
  and has been proven successful in Russian oil
  field operations. The pump possesses the
  simplicity of a plunger-type pump with the heavy
  oil pumping capabilities of progressive cavity
  type pumps. Well operators should find that the
  PDN-44-1200 pump will reduce their operating
  costs and downtime significantly.

ADVANTAGES
The PDN-44-1200 was designed to provide the
heavy, abrasive oil lifting capabilities of the
progressive cavity pumps with the simplicity and
dependability of conventional plunger type pumps.
This design principal provides the following
advantages         The PDN is powered by a
conventional beam pump jack that is less costly
and more reliable than surface hydraulic power
units.         The PDN has been shown to pump
heavy, viscous oil that conventional plunger
pumps were not able to lift.         The PDN has
been shown to operate for one full year without
any needed repairs. This time frame is two to
four times longer than progressive cavity
pumps.         When repairs are needed, the PDN
only requires a few inexpensive replacement
parts. Progressive cavity pumps require the
replacement of the rotor and stator which is
almost as expensive as a new pump.         The
PDN generates a high amount of suction turbulence
at the pump suction area. This turbulence
prevents sand buildup thereby eliminating the
problem of suction blockage.         The cost of
the PDN is less than a comparably sized
progressive cavity pump.
