THE RANGE OF PRODUCTS
The main type of equipment offered to customers is
hydraulic downhole motors used for drilling deviated
and horizontal wells as well as multilateral wells.
By-pass valves for PDM of next sizes
Check valves for drill stems of
Float valves
Turbodrills:
Streamlined core sample
Completion equipment
All the products are certified in accordance with local
and international requirements. Certificates of
accordance such as ISO 9001 and API Specs are available.
The design of downhole motors is protected by patents of
Russian Federation.
Various motor modifications are manufactured
ranging from 43…240 mm, both bent (with an adjustable
and rigid bent) and straight. Bent sub range varies from
0°00´ to 3°00´.
Positive Displacement Motors (PDM) of 120, 127, 172,
195 and 240 mm are widely used for horizontal drilling.
Motors of 95 mm are used for side tracking and drilling.
Motors of 60, 75, 85, 95, 106 mm are used for well
intervention activities.
Motors with adjustable bent are in great demand and
they have wide application: besides drilling oil and gas
wells, they are efficiently applied for building passages
under railways and highways, rivers and other objects
during oil pipeline construction.
In 2009 special R-Wall sections (stator covered with
even resin layer) have been applied to manufacturing of
the motors. There are special versions of the motors for
high-temperature wells.

S i n c e 2 0 0 4 R a d i u s - S e r v i s h a s b e e n
manufacturing, selling and renting drilling and
fishing jars produced jointly with Canadian
company Wenzel Downhole Tolls Ltd.
Jars fleet tool sizes range
Cumulative operating time of Radius-Service jars
fleet exceeds circulation 200 000 hours, more
than 600 repairs were made. Highly skilled staff
and essential equipment are the factors ensured
Radius-Service to repair jars of various designs
and manufactorers.
The jars offered by Radius-Service have a reliable
design, which ensures long operating life and
critical stuck equipment releasing. There are
examples of continuous jarring during two whole
days, which means more than 600 strikes, after
which stuck equipment is released.
The jars are successfully operated by following
Russian and foreign drilling and service
companies: Schlumberger, Baker Hughes,
Halliburton, PetroAliance, Eursia, Orenburgneft,
Technoburservis, SSK, Nedra, Katobneft,
Tyumenpromgeofizika, etc.

JARS PURPOSE:
Jars are intended to release of the tools stuck in
the hole, by jarring upon the sticking area.
Drilling jar is included into the drilling stem
assembly bottom; this ensures jarring action
starting immediately after sticking occurs.
Fishing jar is used for stuck releasing exclusively,
and is mounted into fishing assembly.
Maximum jar operation bottom temperature is
135°C, but after changing of conventional
sealing elements (rings, collars) for thermal-
resistant ones, jar can be operated in the holes
with bottom temperature up to 230°C.

Hydraulic mechanical drilling jar
Hydraulic drilling jar
Hydraulic fishing jar
The jar is intended for striking up and down. The
jar of this design combines features of both
hydraulic and mechanical drilling jars types.
Its mechanical section includes mechanical latch
equipped with Bellville springs pack which
prevents accidental jar action during drilling and
round-trip activities. Upon customer's request
various latch pull-out forces available within the
force range specified in technical characteristics
can be installed.
The hydraulic section includes a valve, equipped
with dispenser. Up-strike force is regulated by
tool pulling force variation during hydraulic
dwell (delay).
Splined jar connection ensures reliable torque
transfer during string rotation drilling.
A distinctive feature of these jars is an absence of
mechanical latch equipped with Bellville springs
pack, which allows extending jar inner opening
and ensures geophysical equipment passability.
There are two valves equipped with dispensers
in the hydraulic section of the jar. This feature
allows jarring upon the sticking area at both
directions with a different force. Due to this
feature these jars can be used in extremely
deviated wells with high friction factor, where jar
recharge axial force can be hardly obtained.
Splined jar connection ensures reliable torque
transfer during string rotation drilling.
The jar is intended to striking upward. The jar
consists of hydraulic and splined sections
isolated from each other by a pack of wear-
resistant sealings.
The hydraulic section includes a valve equipped
with a dispenser. This section ensures strike
force regulation by tool pulling force variation
during hydraulic dwell (delay).
Splined jar connection ensures reliable torque
transfer during string rotation drilling.

CORE SAMPLER
Core sampler is intended for sampling and
delivering of the core during drilling of oil and
gas wells.
All the core samplers manufactured by Radius-
Service can be used both for rotor method of
core sampling and for PDM application. All
samplers are available both in one and two
sections design.
To increase the core delivery and to reduce loads
to housing parts the core samplers can be
equipped with spiral centralizers. The
centralizers diameters are determined by a
customer. The blades at their hole-wall contact
area are reinforced with hard alloy (tungsten
carbide) inserts or with coating material
containing tungsten carbide. The reinforcing of
the working surface can be also made under
Quick-Tip technology. Radius-Service is the
exclusive supplier of this technology over the
territory of Russian Federation.
To provide a reliable core grip a collet core
extractor is manufactured of spring steel. Upon
customer request the extractor can be with
sputtering of industrial diamonds.

RADIUS SERVICE
For core sampling in loose rocks we developed a
lever core extractor which has a larger
overlapped area.
To avoid washouts the valve set is manufactured
of high-hardness stainless steel and is ball-
ground.
Two-butters thread with high torque-capacity is
used in housing parts of 172mm core samplers
which prevents failures during operation with
RPD equipped boring heads of cutting-type.
Core lifter are connected by reinforced profile
conic thread, which prolongs the thread life and
reduces disconnecting risk.
Upon customer request the core samplers can
be equipped with core lifter made of glass-fiber

isolating bit vibrations from the drill string, the
shock tool will reduce lateral and torsional drill
string vibrations, and related fatigue damage of
failure of the rotary connections. The shock tool
allows optimum bit speed to be used under
rough drilling conditions, increasing the rate of
penetration.

INNOVATIVE TECHNOLOGIES
R-WALL power section with even wall thickness
In order to increase torque of downhole motors manufacturers have been following the trend of
increasing the length of power sections. A few years back the length of 3m for power sections were
thought to be a norm. Nowadays, 4, 5 and even 6m are considered as new standards for motor sections.
However, further increase in length is unviable as it comes to technological aspects of drilling, especially
horizontal drilling.
CONVENTIONAL POWER SECTION R-WALL SECTION
Thus, to meet a growing demand of complex drilling activities companies provide the industry with new
solutions. One of them is power sections with uniform rubber wall thickness. This means greater torque
(50%) and horsepower which makes improved penetration rates possible.

Normally rotors are milled. Another possibility is forging. Forged rotors are not dimensionally stable
enough in the axial direction when it comes to high driving forces and high pressures, which are normal
in mud motors. The drive torque deforms the rotor because of its helical shape and therefore the rotor
gets shorter. This could result in the calculated pitch length of the rotor deviating from the stator pitch.
Leaks and drive power losses would be the consequence.
Very strong materials and the sophisticated composite design provide you with a new generation of
power sections, however, which will give you every advantage including very high torsion strength.
The new rotor of the power section is made up of a very strong core tube, which is encased by a
stainless steel jacket tube. This jacket tube forms the necessary, very accurate interference profile of
the rotor. Good profile accuracy (+/- 0.02 inches) is made possible with the new non-cutting
electrochemical manufacturing method.

Thus, this new electrochemical method of manufacturing has been proved to be efficient and reliable.
Downhole motors with new power section have showed excellent performance during field trials. A
significant increase in penetration rate has been noticed. The maximum manufacturing length of the
new power section is 6 meters or 20 feet

For the time being, Radius-Service manufactures the power sections of the following sizes: 95 mm,

Indeed, due to higher cost downhole motors with the new power sections do not intend to replace
motors with conventional rotors. However, in some cases such as drilling of deviated wells with small
radius the R-Wall power sections do not have an alternative choice. Therefore, all improvements
related to R-Wall power sections lead to a major benefit for the directional driller: increased reliability
and longer drilling runs can be achieved at affordable costs.
