This workshop will cover the techniques necessary to manage oil and gas field surface production activities. It provides a discussion and awareness of the different processes used in common production operations like gas and gas condensate treatment as well as oil and water handling. The basic fluid descriptions together with interpretation guidelines will support a better understanding of complex treatment processes. Based on recent treatment processes modern guidelines will be discussed and will improve participants' daily operating skills.
Course Level: Skill Instructor: Wolfram Kleinitz
Designed for you, if you are...
A production or facility engineer, project manager, production chemist, a member of field operational staff currently or potentially involved in natural gas or oil production operations
How we build your confidence
The workshop focuses on practical onsite experience. Case histories and practical examples will be subdivided into the following sections: System description, theoretical background, modern monitoring and control systems, weaknesses in treatment systems as well as the aspects of “over-engineering”. To improve the understanding of actual treatment systems videotapes will be shown and discussed.
By the end of the workshop you will feel confident in your understanding of:
Gas, oil and water properties and their physicochemical behaviour
Oil: Chemical crude oil composition and their characteristics, viscosity, temperature and pressure behaviour
Treated water: Formation water and chemical composition, impact of total dissolved solids (TDS), solubility of organics in water and vice versa, impact of oxygen on produced and injection water
