Direction drilling monitoring station

For safe and reliable guiding of directed and horizontal sections of oil and gas well paths.

The station provides:

  • automatized signal acquisition from process sensors and bottomhole equipment
  • processes workflow monitoring on a well
  • online monitoring of well path
  • calculation of the pathway tolerance range (admissible deflection of hole wandering)
  • building projections for design and actual well paths
  • engineering solutions; BHA design, trip assessment and forecasts
  • identification of cluster wells convergence events
  • identification of drilling problems
  • prompt lithological zonation by geophysical data (gamma, resistivity logs etc.)
  • live data displaying on the rotary site for the DD engineer
  • wellbore report generation and printing
  • export of stored data in LAS, XLS data formats
  • data transmission to remote data storage and processing centers

Well paths calculation procedures:

  • tangential - for S-shaped paths
  • compensated - yields higher accuracy for reduced measurement pitches
  • angle averaging - for flat wellbore paths
  • by curvature radius - for horizontal S-shaped paths
  • two chords method - for S-shaped, steeply inclined paths

Station configuration

  • process sensors set
  • data acquisition unit from telemetry system
  • DD engineer, foreman, supervisor, driller workplaces
  • wireless communication system

Features of the station

  • online monitoring of directional drilling sections processing
  • acquiring actual information for drilling safety provision
  • assessing of current borehole depth hitting a predefined bottom-hole target
  • preventing occasional well paths collision during cluster drilling
  • identification of drilling problem
  • prompt lithological zonation by geophysical parameters (gamma, resistivity logs etc)
  • improving workmanship on directionally drilled borehole sections
