Most drilling problems announce themselves through the same four parameters: torque, drag, pump pressure and returns. What distinguishes the causes is the pattern and sequence. A gradual torque rise with increasing drag suggests cuttings accumulation; a sudden pressure spike with lost returns suggests a pack-off followed by formation breakdown; erratic pressure with no torque change suggests a washout or a tool problem.

The pressure to act quickly is what causes wrong diagnoses. Everyone on the rig wants a decision, and the easiest decision is the one that worked last time. Taking two minutes to assemble the evidence and consider alternatives is almost always cheaper than two days of consequences from acting on the wrong cause.

Lessons rarely transfer without effort. The same field drills the same problem repeatedly because the fix stayed with the people who were there. Capturing what the symptoms were, what the cause turned out to be and what worked, in a form the next crew will actually read, is the difference between an organisation that learns and one that repeats.

By the end of this training, participants will be able to:

• Apply a structured diagnostic method to drilling problems.
• Interpret torque, drag, pressure and returns data for diagnosis.
• Diagnose and respond to hole cleaning and pack-off problems.
• Diagnose and respond to wellbore instability.
• Diagnose and respond to lost circulation.
• Diagnose stuck pipe mechanisms and take correct first actions.
• Diagnose hydraulics, circulation and washout problems.
• Diagnose drillstring, bit and downhole tool failures.
• Recognise well control events and initiate the correct response.
• Make decisions under incomplete information and capture lessons for reuse.

The course is instructor-led and case-based. Participants work through a large number of drilling problem scenarios, receiving data as it would arrive at the rig, forming diagnoses, requesting further evidence and deciding on actions. Each case closes with what actually happened. Participants are encouraged to bring their own unresolved problems for discussion.

Organisations sending participants to this training will:

• Diagnose drilling problems faster and more accurately.
• Reduce non-productive time from misdiagnosed problems.
• Improve first response quality at the rig.
• Spread diagnostic skill beyond the most experienced individuals.
• Build a lessons learned process that changes practice.

Participants will:

• Be able to troubleshoot drilling problems systematically.
• Be able to read rig data for diagnostic evidence.
• Be able to distinguish between problems with similar symptoms.
• Be able to decide and act under time pressure.
• Be able to capture and share what was learned.

• Drilling engineers
• Rig site supervisors and company representatives
• Drillers and senior rig crew
• Toolpushers and rig managers
• Drilling fluids and service company engineers
• Graduate engineers working at the rig site
