This five-day course is designed to discuss the theory, calculations, and procedures associated with the well control aspects of wireline operations. The course consists of lecture, group work and exercises which will aid the participants in understanding the pressure control considerations related to wireline activities. In addition, emphasis is placed on safety aspects, job assignment coordination, and equipment limitations.

Upon successful completion of this course, the delegates will be able to:

·         Perform hydrostatic, formation and force/pressure calculations

·         Identify the safety hazards and equipment requirement/limitations for a snubbing, coiled tubing and wireline operations

·         Identify various tools / equipment and their function/application

·         Competently supervise the well control related aspects of these operations

This course is intended for any personnel that has the responsibility of supervising wireline operations utilizing a lubricator.
