DBOS Drillbit Optimization System

Overview Library

Model, analyze, and adjust drillbit technologies to optimize drilling performance

Offset well data contains insight that can broaden your understanding of the drilling application, subsurface environment, and potential performance. Performing a deep, thorough analysis of available data can help optimize well placement and ultimate production—before a foot of hole is drilled. 

Based in the industry-standard Techlog wellbore software platform, the DBOS system comprises well logs, formation tops, mud logs, rock mechanics, core analysis, bit records, real-time drilling parameters, dull grading condition, and survey data from more than 30,000 wells around the world. 

The highly flexible system allows analyzing multiple tiers of information from a single or multiple offset wells. Projects can be tailored to include multiwell cross section, field-wide mapping studies, and regional trend analyses. 

The system also features a formation assessment workflow that includes

  • geological well log interpretation
  • proprietary algorithms for rock strength, lithology-normalized porosity, abrasion characteristics, and formation impact potential
  • drillbit analysis for roller cones, PDC cutting structure, gauge protection, hydraulics configurations, and high-speed turbodrilling options
  • performance analysis based on energy and mechanical factors
  • statistical interval analysis
  • well correlation
  • field mapping program.

DBOS evaluation process

  • Assessment of expected formation characteristics and their section length based on offset logs
  • Evaluation of key bit performance variables and formation characteristics over the given intervals
  • Identification of the most suitable bit for drilling through a one or more intervals based on field experience data and knowledge-based heuristics
  • Optimization of bit design and determination of interval cost per foot with a greater certainty and reduced risk
  • Postrun evaluation of bit performance based on actual well parameters and bit dull condition for feedback into the DBOS system for continuous improvement.
