Discipline: Production and Completions Engineering
Level: Intermediate
DESIGNED FOR
Production engineers, facility engineers and technicians dealing with well and near well operations, who are responsible for recognizing and treating problems which require chemicals.
YOU WILL LEARN HOW TO
- Recognize corrosive conditions and monitor corrosion rates
- Select and apply corrosion inhibitors
- Predict and treat emulsions
- Understand causes and control of foaming
- Predict scale forming conditions
- Select and apply scale inhibitors
- Control gas hydrate formation
- Predict and control paraffin (wax) deposition
- Evaluate methods for asphaltene control
- Scavenge low concentrations of H2S
- Select and apply water clarifiers
- Select chemicals for use in deep water
- Select environmentally friendly chemicals
This course covers the selection and use of chemicals used in oil and gas production.
As oil fields mature more water is produced which requires the use of more chemicals to maintain production. Chemicals used for controlling corrosion, emulsions, foaming, mineral scales, paraffins (waxes), asphaltenes, gas hydrates, hydrogen sulfide scavengers and water clarifiers are covered. The course includes methods to determine the need for chemical treating, how to select the proper chemicals, and how testing for chemical compatibility with the formation and other chemicals is performed. Requirements for environmentally friendly products and products for deep water production are discussed. The course will include how the use of chemicals can prevent problems, improve production and economics, and extend the life of the well.
This course can be offered on an in-house basis dealing primarily with corrosion and the use of corrosion inhibiting chemicals. The corrosion material and examples covered this five-day course would be expanded and detailed examples and problems worked. If interested in this option, contact PetroSkills.
