COURSE OVERVIEW

Oilfield microbiology is an often-overlooked aspect of production chemistry. Uncontrolled microbial activity in oilfields can lead to significant asset integrity, safety, and environmental problems, which cost a lot. Their leading causes are reservoir souring, microbiologically influenced corrosion (MIC), and process upsets. These issues can be avoided by taking a proactive approach to microbial monitoring and mitigation to save money and improve production.

This Oilfield microbiology course covers the basic problems that microorganisms cause, including reservoir souring, MIC, and process control upset. You will know how best to monitor and mitigate microorganisms from both a theoretical and practical point of view through case study classroom work and laboratory microbial monitoring and testing techniques. Participants will have a complete understanding of the causes of microbial reservoir hydrogen sulphide souring and the actions and processes needed to reliably predict, monitor, control, and manage the risks of souring.

LEARNING OBJECTIVES

Upon completion of this Oilfield microbiology training course, participants will:

  • Understand the different types of microorganisms.
  • Learn microbiological processes as applied to the reservoir.
  • Determine how they cause souring and corrosion.
  • Develop an understanding of the various microbial souring prediction tools available.
  • Assess data supplied on existing biocide formulations and other microbial control measures appropriate to the system.
  • Identify solutions for monitoring and mitigation programmes.
  • Be able to establish a proper souring monitoring program for the operation.
  • Be able to interpret field data on microbiology and souring accurately,
  • Recognizing how to assess the effectiveness of any applied souring mitigation strategy
  • Determine and recommend any needed changes to the strategy, including biocide evaluation and optimization.
  • Set up appropriate sampling locations.
  • Take accurate samples and learn preservation techniques for further laboratory analysis.

TARGET AUDIENCE

This course is suitable for a wide range of professionals but will greatly benefit:

  • Reservoir Engineers, Production Engineers, Operations Personnel, Technical Personnel, Management Personnel and Research & Development Personnel
  • Anyone who is controlling and managing microbial reservoir souring.
  • Anyone wishing to improve their understanding of microbes in the oil industry

TRAINING METHODOLOGY

This Oilfield microbiology course utilises various proven adult learning techniques to ensure maximum understanding, comprehension, and retention of the information presented. The programme will be interactive and practical. There will be work in groups and pairs as well as individual exercises, and everyone will get an opportunity to discuss his issues.

Pre & Post course assessments will be used to measure the effectiveness of this training.
