Advanced Well Completion Engineering Technology

The course presumes a general engineering or scientific background. It requires some basic knowledge of completion and production technology. It combines a review of the fundamental concepts of the subjects covered together with their practical application.

This 5-day course is aimed at petroleum, production and operation engineers who wish to gain an insight into some of the more advanced aspects of completion design. It will be run on a workshop style basis where the attendees will have the opportunity to select from the subjects listed below.

Course Objectives

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

• Understand the well performance inflow & outflow, coiled tubing and downhole oil/water separation
• Perform the selection of Artificial Lift Techniques
• Familiarize in gas lift and formation damage
• Deal with Acidising Matrix Acidising Treatments and conformance control
• Deal with optimizaion of hydraulic fracturing

Who Should Attend?

This course is intended to all Engineers (both Operating and Service Company personnel) who are already familiar with the basic completion processes, but have a need to extend their area of understanding to cover more advanced aspects; but who cannot justify attending a number of separate courses which are often targeted at teaching specific software. It would thus also suit Production Staff, Engineers from disciplines other than Production Technology etc.
