FT. WORTH, Texas--()--Varel International Oil and Gas, the world’s largest independent supplier of drill bits for the oil and gas industry, announces the commercial launch of the new IMax™ series diamond impregnated drill bits for hard and abrasive formations. The highly flexible series, available with a hybrid cutting structure design, can be equipped with turbine sleeves and box up connections.

The high-performance IMax series bits are based on the latest in design, material and manufacturing science and optimized to drill faster and last longer in challenging applications.

The product line features:

  • Strict diamond selection ensuring diamonds of similar size and quality
  • New pelletization process, preventing diamond aggregates and reducing areas of low diamond concentration
  • Improved diamond/matrix bonding
  • Infiltration in controlled temperature environment for reduction of oxidation and graphitization, resulting in improved bit wear characteristics and durability
  • Cylindrical, hot isostatic pressed (HIP) segments tailored to the formation
  • Custom cutting structure design by proprietary SPOT™ bit design program

“The IMax series is the result of combining the best practices in impregnated drill bit design, new materials and manufacturing processes,” said Cary Maurstad, Global Product Manager for Fixed Cutter and Roller Cone Drill Bits. “Taking these individual pieces and finding their exact balance led to the development of an all new product series for Varel.”

Maurstad continues, “Our field tests have validated our efforts and we are excited to deliver this solution to our customers for their tailored drill bit solutions.”

IMax+ Provides Hybrid Cutting Options

IMax+ adds premium Vulcan® PDC cutters for a hybrid design with a dual cutting structure. The bit design is particularly effective in less-consolidated sandstones or when drilling from a softer formation into a harder and more abrasive formation, where durability is key. PDC cutters are strategically located on the cutting structure for increased formation shearing. As the formation becomes harder or more abrasive, the PDC cutters wear down to expose the HIP cutting structure to the formation.

Varel subject matter experts will be on-hand for the announcement of the product launch during the evening reception Tuesday, March 4, at the 2014 IADC/SPE Drilling Conference, booth #104.
