Oil and Gas
This one-day course provides a comprehensive overview of the design and operational aspects of acid gas compression and injection projects. The presentation includes a detailed discussion of the phase behavior of acid gas and outlines the methods for estimating the properties of acid gas for the design of the compression and injection facilities. It also addresses the methods for controlling corrosion and prevention of the formation of hydrates. Design considerations of compression and cooling equipment, injection line, well completion, and reservoir selection are also discussed. Technical and operations persons involved in the design or operation of acid gas injection projects would greatly benefit from this course. A comprehensive set of course notes is included.

Who Should Attend and Prerequisites
This course is intended for engineers and technologists involved in the specification and design of acid gas compression facilities, and for foremen and operators responsible for the daily operation of such facilities.
Edward Wichert has an extensive background in the oil and gas industry. This includes experience at the technical level as well as in management in drilling, oil and gas production and processing, reservoir engineering and economic analysis. He gained this experience through employment in the oil and gas industry in Alberta, with small, intermediate and large companies. He holds a B. Sc. degree in Petroleum Engineering and a Master's degree in Chemical Engineering. His research interests are mainly related to sour gas. He has published several articles dealing with determining the properties of sour gas and the application of technology in sour gas production and processing, as well as the disposal of acid gas by compression and injection.
He is an independent oil and gas industry consultant in Calgary, and was Adjunct Professor in the Department of Chemical and Petroleum Engineering at the University of Calgary from 1996 to 2005. He has presented courses in natural gas technology worldwide, and is the recipient of the Award of Merit from the Canadian Gas Processors Association, in 1994, the Lifetime Achievement in Hydrocarbon Measurement award from the Canadian Institute of Hydrocarbon Measurement, in 2003, and the Project, Facilities and Construction Award from the Society of Petroleum Engineers. He has recently written a comprehensive book on the technology of sour gas production, gathering, treating, and the different methods of acid gas disposal.
