Drill Bits & Services

NewTech Services Holding Limited, a sister company of Frontier International, is a leading drill bit manufacturer and service provider in Russia and CIS. The company’s Drill Bit & Services has highly trained service and product specialists to address the most challenging drilling environment. These specialists integrate reservoir knowledge, customer requirements, and the industry’s leading software to maximize bit design and performance.

PDC HYDRA™ Series

HYDRA™ is an application enhancing program that combines hydraulic requirements along with cutting structure needs to design an application specific bit.

Unique features are apparent with webbed blades, curved nozzles, and engineered junk slot designs. Combining the two technologies CFD and the cutting structure design has led to breakthrough designs for the industry that are original. New records are being set every day with HYDRA bits.

Application:

• Vertical, Directional, Horizontal, and Tangent wells.
• For soft to hard formation applications.
• For all rotary, directional motor, and RSS applications.

Features /Benefits:

• Curved nozzles reduce the stream impact to the formation eliminating erosion and increasing bit stability in soft to medium formations.
• Webbed blades reduce cuttings recirculation to other junk slot areas, eliminating the regrinding of cuttings.
• Application-specific cutting structures and bit blade/junk slot designs to match formation requirements for cuttings removal and ROP.
• Better cleaning and cutter cooling leads to extended bit life by reducing plugged nozzles, core outs and bit balling.
• Unique junk slot geometry improves cleaning efficiency for higher cuttings volume.

VOYAGER Series

Voyager series PDC bits are specially designed for extended-reach wells with a high dog leg severity. The VOYAGER line of PDC bits delivers smooth torque, advanced directional control, excellent well bore quality, and dynamic stability to meet the challenge of any directional application.

RAIDER Series

A new series of Raider bits was developed to create a new, more balanced profile, with greater stability to overcome the ROP and durability challenges of drilling transition zones and abrasive formations. The Raider series enables drilling into densely interbedded soft to hard formations with transition zones without experiencing a significant vibration and changes in drilling parameters.

FUSION Series

Fusion and Fusion+ series of the matrix bits with Diamond Impregnated HIP segments drill faster and last longer through hard and abrasive formations. The design is particularly effective in less consolidated sandstones or when drilling from a softer formation into a harder and more abrasive formation. FUSION represents optimal drilling performance in very challenging formations.

PREMIUM CUTTER TECHNOLOGY

Key diamond attributes can be enhanced to better match the demanding drilling needs. By selecting the diamond blend that best suits the need, the cutter will stay sharper, longer. The precision of the cutter attributes becomes increasingly important to overall bit performance where thermal damage, abrasion, and impact are present.

New Approach Defining PDC Cutter Properties

Working with our principal supplier US Synthetic, Varel NTS is now using four main attributes to define its latest cutters.

• Abrasion Resistance measured by cutting granite (VTL wet)
• Thermal Stability measured by heating cutters in controlled conditions to give first cracks (VTL dry)
• Crack Propagation Energy required to generate a crack in the diamond table
• First Crack Energy required for cracks to propagate across the cutter

Application Matching — Venom™ Cutter Technology

We match Cutter Type to the field by defining the typical bit dull and cutter failures, modelling the rock drilled, defining well profile, BHA and drilling parameters. Providing the cutter with the right attributes will give the bit the best chance of success. Knowing which cutter attribute to focus on ensures the bit is properly equipped.

The VENOM™ Cutter methodology matches the right diamond and the right cutter shape to maximize cutting efficiency and eliminate risks by identifying cutting structure, rock characteristics, RPM, WOB, mud weight and BHA drive type (RSS / PDM).

ARTIMIS

Leading edge geometry creates a stress point in the formation to pre-fracture the rock. Application is hard formation with heavy transitions, such as cherty formations.

FANG

A sharp-edged cutter to pre-fracture the rock as a backup or secondary cutter. Increased drilling efficiency gives higher ROP at lower energy levels.

COBRA

Latest shaped cutter increases drilling efficiency by fracturing and shearing rock.

SCOOP

A concave shaped cutter allows reducing the cutting angle — up to negative values. This feature allows to design extremely aggressive cutting structure.

Varel NTS and Frontier International are fully equipped with the software suite designed to enhance the engineers' ability to develop drill bits for specific applications.

GeoScience™

When designing a new PDC bit, the first step is to evaluate the rock for its physical and mechanical properties.

The GeoScience™ software suite facilitates geological interpretation of geophysical logging data that translates into strength and abrasivity computations for the sections being drilled. After obtaining a quantitative estimate of the interval's strength, a technical expert will also compare the drilling parameters, analyze geological anomalies and assess the associated bit wear.

As a result, the engineering team will be able to identify intervals of varying formation properties and use this knowledge to make correct design decisions for future drill bit projects. GeoScience requires a log dataset in the .las format.

SPOT™

SPOT™ is a drilling design software used to perform PDC bit structure simulations with the goal of matching the design to particular drilling conditions.

Engineers working on new bit designs will seek an optimal balance of speed, durability and controllability in view of the design goals and geological survey data processed in the GeoScience™ software. SPOT™ software accounts for multiple factors and design options by using the verified mathematical algorithms. The final design is validated by running a simulation of the drilling process. This step ensures that the configuration is tailored precisely to the drilling conditions.

CFD

The final stage of PDC bit design involves hydrodynamic simulation.

With CFD software, the nozzles can be modelled in an optimum pattern to ensure effective removal of cuttings from the bit and the bottom of the hole. In addition, with CFD the engineers analyze specific fluid flow modes to detect abrasion-prone spots or stagnant zones and then optimize and re-test the configuration until the desired results are achieved.

At Frontier International, we strive for technology & execution excellence and we value partnerships to strengthen it.

In 2012 Varel International Energy Services and NewTech Services, a sister company of Frontier International, opened a drill bit manufacturing plant in Kurgan, Russia, with the capacity of producing 1800 bits/year.

The new facility is at the heart of the Varel NTS joint venture, which aligns Varel's high technology engineering and manufacturing with the strength of NewTech Services (NTS) in drilling technology, infrastructure, market knowledge, and customer requirements.

Centrally located to facilitate rapid bit delivery across the CIS & East European markets, the Kurgan plant incorporates the most advanced global technologies and tools for manufacturing and servicing oil and gas drill bits for the local market and beyond. Staffed with key personnel who trained at the Varel manufacturing facilities in France, the Kurgan plant increases the drill bits reliability and services quality to the highest industry standards.
