OBJECTIVE

WHO SHOULD ATTEND:

The course is designed essentially for process and mechanical engineers employed by the operating companies engaged in oil and gas production. The material is also appropriate for those personnel concerned with specialist functions in the oil industry including inspection, material selection, and corrosion control as well as for those involved in R&D. Staff of service companies providing corrosion inhibitors and overall corrosion services should also find the course beneficial, together with companies or manufacturers marketing materials, coatings and equipment for cathodic protection, inspection (NDT) and corrosion monitoring. The course is also intended for government agencies and process plant contractors involved with oil and gas production. A prior knowledge of corrosion is not a prerequisite to attendance, as a short introduction to the subject will be presented.

LEARNING OBJECTIVES:

Upon completion of this course, you will gain knowledge of corrosion engineering in oil and gas production involving the various methods available for corrosion control', regulatory and safety matters, and the contribution of an integrated monitoring and inspection program for operations and the diagnosis of problems.

COURSE DESCRIPTION

Corrosion problems have always presented a severe challenge to oil and gas producing operations. Operators plan for long periods of continuous production with maintenance scheduled for the prescribed shutdown periods. Unfortunately, corrosion does not always respect these schedules, resulting in severe economic penalties due to loss of product. In addition the risk of pollution and hazards to safety are other important reasons for adequate corrosion engineering.

Governmental legislation concerning oil and gas extraction is becoming more stringent in order to minimize these risks. Furthermore, corrosion hazards have intensified with extraction in deeper waters and in more hostile environments. Innovations aimed at reducing offshore field development costs involving reductions in platform weight, increasing use of satellite wells and subsea manifolds require specific attention to corrosion prevention.

The course considers external protection using corrosion resistant materials, coatings, and cathodic protection. The importance of internal corrosion and its prevention will be examined with emphasis on material selection, coatings and use of corrosion inhibitors. The contribution of inspection (nondestructive testing), and corrosion monitoring to the overall operation will be considered in detail. Corrosion problems concerning "risers" and subsea-lines will be considered together with methods for protection. Various corrosion-oriented software, including Corsur TM and Corsur 2 TM will be demonstrated and available for use by participants.
