Drill Bits

Endevour offers optimal solutions to provide the Customer with drilling bits, including the selection of the optimum type and design, the supply and run of PDC, tri-cone, impregnated and hybrid drilling bits to perform a wide range of tasks. Bits can be provided for sale, lease or “pay by meter” service.

Our engineers carefully investigate all available information on lithology, analyze data on offset wells, existing well designs and procedures. Based on this analysis, they select each bit according to the specific drilling conditions and Customer’s requirements. As a result, the Customer receives optimized drill bits solutions that contribute to the most effective achievement of the set of specific goals.

The service is provided with partner expert support from the global leader in the development and manufacturing of drill bits – the National Oilwell Varco company, which guarantees access to the latest technology in the industry, and the successful search for the most economically efficient and reliable solutions. Bit selection, modeling of their work conditions, optimizing BHA and vibration analysis is performed by using specialized NOV software TerraScopeTM and VibraScopeTM.

Drill bit service includes:

  1. Drill bit program design, including the vibrations analysis and BHA optimization.
  2. Timely bits delivery on the well.
  3. Field engineering support of “pay by meter” bit run on the well, including the following:
  • calculation and optimization of drilling hydraulics;
  • preparation of bits to RIH;
  • analysis and recommendations on BHA;
  • instructing drilling crew on proper use of the bits (BHA assembly/disassembly, running through possible complications areas, bit breaking-in, etc.);
  • calculation of optimum drilling parameters and their monitoring;
  • preparing of daily and run reports;
  • IADC dull grade evaluation;
  • performance analysis of run, development of recommendations as per the drilling results.
  1. The final report on the well or drilled intervals with conclusions and recommendations for improving the ROP for next well of the field, reducing NPT and risk of complications while drilling.
