Drilling Fluids Training

Drilling Fluids Training

OFITE presents drilling and completion fluids seminars and schools at our facility in Houston, Texas. Classes are led by David Breeden, a consultant with over 35 years of experience in all aspects of drilling fluids technology, marketing, R&D, and operations.

Who Should Attend

These classes are designed for drilling and completion engineers, geologists, rig supervisors, chemical sales representatives, R&D technologists, oilfield managers and supervisors, supply-chain personnel, and service company personnel. Classes meet the needs of a broad range of interests. Attendees can choose the class level that best fits their requirements, from basic information to advance mud technology.

NOTE: These are not mud schools needed to qualify a person as a mud engineer, but rather classes that provide industry information through a combination of lecture and laboratory exercises.

Course Description

Drilling is a complex operation requiring the combination of different technologies and disciplines. Today’s drilling personnel must have a working knowledge of drilling fluids in order to effectively drill a well. This course covers all aspects of drilling fluids technology, emphasizing both theory and practical application. Hands-on laboratory exercises are included.All pricing subject to change without notice.

  • Use clays and polymers to achieve desired mud properties
  • Apply water chemistry to the treatment of drilling fluids
  • Perform complete API drilling fluids tests and evaluate the results
  • Identify drilling fluid contaminants and develop corrective treatments
  • Select water phase salinity and activity for bore hole stability
  • Select non-aqueous fluids to meet drilling and environmental requirements
  • Manage non-aqueous drilling fluid systems
  • Minimize formation damage to optimize well production

Upcoming Dates

We are postponing all in-house training classes until we have more information regarding restrictions due to COVID-19.

How to Register

Please pre-register for classes here, and a representative will contact you. All schools and seminars include lunches, training handouts, and a copy of the slide presentations.

The course costs $3,950 per student. There is a 10% discount for additional attendees from one company.
