E-536 - Oil & Gas Field Processing Troubleshooting

5 days PROC/TROUBLEGB
Level
Proficiency
Audience
  • Operation Support Engineers, Production Supervisors and Superintendent looking to acquire best practices of Oil & Gas production facilities troubleshooting.
Purpose
  • To contribute to troubleshooting operations identifying and tackling of process deviations and abnormal conditions using a structured, step-by-step approach.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • assist common Oil & Gas production operations and explain normal operating conditions,
  • efficiently use DCS tools to gather information, analyze process deviation, assign priorities and take action,
  • identify roots causes to process deviations and abnormal conditions by using a structured, step-by-step approach,
  • list common issues on main O&G processes and major equipment.
Prerequisite
  • No prerequisites for this course.
Ways and means
  • Highly interactive training with industry specialist lecturers.
  • Methodology illustrated by multiple industrial case studies.
  • Numerous process troubleshooting exercises using dynamic simulator replicating a DCS environment.

Methodology 1 day
  • Troubleshooting flowchart.
  • Recognize a trouble when occurring - Problem definition using ISHIGAWA fishbone chart.
  • Methodological approach to identify causes and remedial options. Action plan. PARETO chart.
  • Implement operational/design modification. Management of change & Feedback.
  • Troubleshooting toolbox.
Case studies 1 day
  • EFR compressor failure.
  • Glycol & hydrate inhibition.
  • Injection water scaling.
  • Emulsion case.
  • Desalting scheme.
  • Pipeline network analysis.
  • Flowline erosion.
Case studies using DCS replica 3 days
  • During this three days, case study are performed using a dynamic simulator replicating a DCS environment in order to allow the participants to understand process dynamics and typical instrumented systems and to efficiently use DCS tools to collect information needed for troubleshooting.
  • On top of understanding process dynamics, the course focuses on efficient usage of DCS tools (trends, historian, alarm summary, safety views, …) in order to identify and react in a structured manner to common process upset. In particular, the course focuses on the need for anticipation, the use of trends and historians to identify/characterize process deviations.
  • Example of case studies performed on simulator:
  • Severe slugging from a production flowline.
  • Foaming in a separator.
  • Heat exchanger leak.
  • Instrument failure (transmitter, valve, …).
  • Off-spec gas dehydration.
  • Loss of a compressor.
  • Limited gas lift.
  • Overpressure in a storage tanks.
  • Gas leakage to the flare.
  • Partial loss of cooling water.
  • Production rate decrease.
