Course Description:
This Course is Designed for a wide range of oil and gas water facilities technicians from senior management to those new to the industry, the course form an overview into the role of chemistry in oil and gas production, and how additives and chemicals can be applied to control formation and prevention of oilfield scale and corrosion, and hence to combat natural production challenges.
A comprehensive five-day course covers such subjects as organic and inorganic scale deposition and control; corrosion; crude dehydration; water injection; chemical compatibility flow assurance; and fluids processing. It also demonstrates how process design and chemical applications can be used to improve treatment and recovery.
