Oil Gas Production Chemistry
Description :
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
