Objectives This 5-day course is a unique blend of technical and highly practical materials designed to help operation people achieve trouble free drilling.  The course is highly focused on integrating all available to data to track drilling trends, diagnose anomalous trends, correctly and proactively respond to impending problems, and if it occurs, clearly define first and second actions by drillers and other team member of the will help the participants understand how

The course is built around hands on case studies which is designed to show the participants how to work with field data and arrive to correct diagnostics of problem root causes.   This course is first in industry to integrate multi disciplines to analyze a problem.  The course heavily focuses on analyzing collectively pre drill G&G data (seismic), real time data (LWD/mud logging/others), geology, geomechanics, and pore pressure evaluation.  Such broad and in-depth practical integration of information brings to light the essence and root cause of the hole problems.

In short, the course is highly focused trouble shoot hole problems by analyzing all kind of data and provide correct action, prevention, and mitigation (no shooting from hub)

This course is designed for Derrickmen, Drillers, Tool Pushers, Drilling Supervisors, and Drilling Engineers with field experience.  In addition, all well planning team from G&G can benefit greatly from this course as the topics addresses their role in well planning for trouble free drilling.  The course is intended to include both rig and office-based personnel. Who should attend?   Anyone who is connected with well construction from the planning phase to post mortem including drillers, tool pushers, drilling engineers, geologists, crew members, and service personnel. What you will learn

  1. Prevention of hole problems
  2. Interpreting well trends
  3. How to integrate all relevant data from geology, pore pressure, wellbore and global geomechanics perspectives.
  4. Hands on analysis of pore pressure prediction and regional stresses assessments and their role provoking or causing hole problems
  5. How to recognize when the problems are beginning to occur
  6. The first actions to take at the onset of a problem.
  7. Freeing procedures (drill string calculations) if the pipe should become stuck.

Course Materials The course will be delivered using a mixture of power point presentation, a course manual, and some use of software tools.

Day 1- Day 5


  • Introduction and pre-test • The chain of events
  • Communication and team morale
  • Well planning for trouble free drilling
  • Demonstration of well planning process using seismic data
  • Definition of torque, drag,
  • Stuck Pipe Mechanism
  • Differential sticking (review of physics, first actions and prevention)
  • Class case studies



  • Review of mechanical causes of stuck pipe (shale instabilities, hole cleaning)
  • Review of wellbore geometry problems
  • Loss of circulation, diagnostics, prediction of fracture gradient and LOT interpretation
  • Assessment of preexisting fractures from well log data and linking to LOT, losses, and wellbore stability.
  • Class case studies


  • In depth review of caving analysis to diagnose down hole problems and correct response
  • Drill solids analysis and mud properties
  • Basic drill string calculations
  • Hole problems diagnostic worksheets
  • Primer on pore pressure evaluation
  • Hole cleaning calculations for vertical and directional wells
  • Class Case Studies


  • Jar placements
  • Back reaming operation
  • Geological perspective to hole problems
  • Regional geomechanics: earth stresses assessment and optimum well direction
  • Primer on wellbore stability
  • Drilling shale underbalanced


  • Class workshop on several field cases which integrate seismic, geology, real time data, in evaluating hole condition, diagnosis of root cause, and device correct response.

Students will use well logs to assess pore pressure and downhole stresses, evaluate hole cleaning requirements, assess drilling fluid health, link their evaluation to observed torque and drag, and well behavior in general.
