Oilfields 101

Oilfields 101

August 12-13, 2019 | Pittsburgh, PA

This course will present an overview of oilfield operations, both subsurface (downhole) and surface.  The downhole portion will present an overview, and then drill down into actual data from well files, and how the information in the files relates to the reality in the well.  The facilities topics covered will include liquids and gas gathering and processing.

The intent is that participants will be able to apply the information learned the first day they return to their jobs.  The information will be presented in terms of diagrams and photos of real equipment, and real example documents.  The information will not be a gussied up “ideal” case, but will show the equipment or documentation as we actually experience it.  Lessons learned from the instructor’s experience will be incorporated throughout.

Learning Outcomes

Attendees to this course will

  1. Get a foothold in comprehending drilling and production reports and other documents that typically come across their desks
  2. Grapple with acronyms and jargon, and recognize that they are not the only one who doesn’t understand them
  3. Relate concepts about fluids, pressure, and rate to the operations that take place in oilfields
  4. Describe the structure of the industry and the organizations within it, and identify communication paths within and between organizations as well as key vocabulary terms and scheduling processes
  5. State information about key points of environmental compliance
  6. Recognize the function of equipment items, procedures, and mechanical devices used in the oilfield developments
  7. Recognize practices that improve efficiency in operations
