Advanced Technologies
Finite Element Analysis (FEA) of an insert hole
GeoScience builds a virtual model of the geology
of the well sections to be drilled.
Advanced Technologies for Design Analysis
Varel engineers utilize Computational Fluid Dynamics (CFD)
to simulate fluid flow around roller cone bits and evaluate
design hydraulics prior to field tests. CFD analysis allows
nozzle orientations to be optimized to eliminate fluid
stagnation zones, and to ensure cone cleaning and hole
cleaning are efficient and enable maximum penetration rates
to be achieved.
Finite Element Analysis (FEA) is employed to analyze new
roller cone bit designs in the early stages of the process to
ensure product reliability under a wide variety of operating
conditions. The insert hole and bearing geometries are
analyzed through FEA and designed to withstand the high
loads encountered in severe drilling applications.
GeoScienceTM
is Varel’s proprietary well log, lithology, and rock
property analysis software. Varel has developed proprietary
algorithmic analytical capabilities to create a leading tool
for drill bit applications analysis. Using customer-supplied
mud logs, drilling logs, and electric log data, Varel builds
a virtual model of the well sections to be drilled. Historic
bit performance is evaluated using a specific energy method
that allows for correlation across different bore diameters.
The GeoScience technology and method leads to a far better
understanding of the drilling challenge to be met and assists

Proven technology meets enhanced features
The new High Energy product line consists
of our 7½ to 13¾ sealed journal bearings
with tungsten carbide cutting structures.
The bits are built with time-proven O-ring
seal technology, but with new features
that greatly enhance the effective life of
the seals. First, a patented conical seal
gland design has been employed. This
new geometry positions the seal in such
a way that it can better handle pressure
fluctuations and still maintain a preferred dynamic sealing location
and interface. The new seal gland is further complemented by an
industry exclusive heat shield deployed between the seal and the
inner bearing. This shield provides life extending thermal insulation
to the seal from heat generated in the bearing. The result is a lower
operating temperature for the seal that also extends seal life.
An improved seal and bearing system
The High Energy Series includes
innovations that increase bearing
life and seal protection. Engineers
developed a bearing system designed
to support higher loads on the
bearing surface, which resulted
in a more robust and more tightly
toleranced journal bearing. In
addition, a new anti-shale packing configuration is incorporated,
improving cuttings diversion away from the mud side of the
seal gland.
Self-draining reservoir
We have incorporated a larger
dome-vented grease reservoir into
the bearing system that is capable
of delivering bearing lubrication
over longer, higher load and higher
RPM runs. This new reservoir
provides a 13 percent increase
in capacity over previous designs
and is configured to be “self-draining” to avoid cuttings buildup
adjacent to the reservoir. This feature improves the reliability
of reservoir performance when a High Energy Series bit is rerun.
Increased wear resistance
To ensure greater durability, we have
incorporated a new shirttail hard
metal formulation that significantly
increases wear resistance in this
critical area of the bit. Upgraded
shirttail enhancements including
leading edge shirttail inserts,
stabilization inserts and diamond
enhanced shirttail protection are available.
High Energy Tumbled (HET) cutting performance
This proprietary process for improving the attributes of tungsten
carbide inserts (TCI) overcomes the traditional trade-off between
wear resistance and fracture toughness of tungsten carbide
components and actually makes TCI components both harder and
tougher. The HET process constitutes one more quality assurance
step in the manufacturing of tungsten carbide inserts. We
manufacture the inserts used in our products and control all of the
HET processing and inspection of inserts.
As a leading manufacturer and global supplier to the drilling
industry, we are proud to introduce the next generation
in drill bit performance – the Varel High Energy Series.
This innovative series ushers in a new line of roller cone bits capable of increasing drilling performance by
effectively utilizing higher energy inputs in the form of increased rotary speed, increased weight on bit, or both.
To create the High Energy Series, our engineers used an integrated systems approach. At every point in the
development process, each element was refined and enhanced to add to the durability and drilling rate of
these bits. As a result, our High Energy Series bits are able to withstand applications where the combination
of bit weight and rotary speed is at the high end of the spectrum, and by doing so deliver better performance
in critical applications.

Compass series bits have proved highly effective across the spectrum of slimhole operations.
Available in sizes ranging from 3-3/4” to 7-3/8,” Compass tungsten carbide insert bits meet the
extreme demands of slimhole applications.
In one slimhole application for a major operator in Western Canada, a 158.7mm Compass bit
was challenged to increase meters drilled while maintaining an acceptable rate of penetration
(ROP). This application requires the bit to pass through increasingly hard formations including
the abrasive, sharp sands of the Cadomin/Nikanassin formations. Varel supplied the operator
with the Compass CM44DMRS bit, equipped with a diamond enhanced back row, leading edge
shirttail inserts and stabilization inserts. The bit drilled 180 meters, down to 1985 meters
depth. This performance netted a 19.4 percent improvement in meters drilled when compared to
the closest competitor offset and a 31 percent improvement in ROP.

To enhance gage holding and seal protection, Varel
roller cone bits provide value with a variety of shirttail
protection packages for high-angle drilling, abrasive
formations and steerable applications. These shirttail
protection packages can be used to tailor bits to meet
your drilling needs.
› Shirttail Hardfacing (M Feature)
For demanding motor applications, a generous
application of tungsten carbide hardfacing is applied to
the shirttail lower edge and leading edge of the bit leg
to provide enhanced seal protection.
› Leading Edge Shirttail Inserts (S Feature)
Tungsten carbide inserts are placed along the leading
edge of the shirttail providing additional wear resistance
in motor applications commanding high RPM or where
additional shirttail protection is needed.
› Stabilization Inserts (R Feature)
Stabilization inserts enhance standard shirttail patterns
by providing bit stabilization and additional protection to
the pressure compensator in high-angle applications or
in deviation-prone formations.
› Diamond Enhanced Shirttail Inserts (Z Feature)
In Varel’s premium shirttail protection package PCD-
capped inserts replace tungsten carbide inserts (TCI) in
strategic locations to provide maximum shirttail protection
in abrasive formations or directional applications.

› Diamond Enhanced Back Row (D Feature)
Carbide, back-row inserts are replaced with polycrystalline
diamond (PCD)-capped inserts to increase gage holding in abrasive
applications.
› Diamond Enhanced Gage and Back Row (DD Feature)
Back row and all gage inserts utilize PCD-capped inserts to maximize
gage holding.
› Fully Diamond Enhanced Cutting Structure (D3DD Feature)
All inserts are PCD-capped to extend bit life in the most extreme
drilling conditions. The premium D3DD package features a fully
PCD-clad cutting structure providing excellent wear resistance
in the harshest environments.
› Tungsten Carbide Coated Cones (E Feature)
All exposed portions of the TCI cones are coated with tungsten
carbide to provide maximum resistance in applications where cone
shell erosion limits bit life.
› Steel Center Air Jet Nozzle (H Feature)
Air type bits offer an optional center air jet nozzle featuring three
additional ports for enhanced cutting structure and enhanced hole
cleaning. (Available only in 7 7/8 bits and larger)
› Center Jet Nozzle (J Feature)
A fourth interchangeable jet is installed in the center of the bit to
reduce bit balling or provide extra flow capacity. (Available only in
7 7/8 bits and larger)
› V-Jet Hydraulics (V Feature)
The V-Jet aimed flow stream produces better cone cleaning, which
improves bit penetration rates. In addition to new head forgings,
the new designs maximize leg strength while minimizing overall bit
length, helping to deliver more hydraulic horsepower to the hole
bottom.

High Energy Tumbled (HET)
Patented High Energy Tumbled (HET) cutting performance
This proprietary process for improving the attributes of tungsten
carbide inserts (TCI) overcomes the traditional trade-off between
wear resistance and fracture toughness of tungsten carbide
components and actually makes TCI components both harder and
tougher. The HET process constitutes one more quality assurance
step in the manufacturing of tungsten carbide inserts. We
manufacture the inserts used in our products and control all of the
HET processing and inspection of inserts.
