COURSE OVERVIEW

The main elements of the subsurface production system include the reservoir, wellbore, tubing, perforation techniques, packer, SSSV, artificial lift equipment and wellhead. Understanding the integration between the elements of the subsurface production system along with the principles of the Inflow and outflow relationships is very important to be familiar with the well productivity and production optimization. Formation damage has a great impact on the productivity of oil and gas wells. Therefore, stimulation operations are used to remove the formation damage and enhance the productivity of the well. However, the artificial lift techniques are used to decrease the bottom-hole pressure and increase the production rate from the well. The various types of artificial lift systems along with their selection criteria should be studied to achieve production optimization.

This course provides an overview of well-performance evaluation leading to the determination of well conditions necessitating the application of artificial lift and stimulation operations. All causes of the formation damage (during drilling, cementing, production) and the remediation techniques will be presented. The practical aspects of the most important artificial lift methods will be covered. Several case studies including guidelines, approaches and procedures will be also presented for better understanding of the subsurface production operations and the artificial lift technologies.

TRAINING METHODOLOGY

Our highly practical experiential learning method is results-oriented; based on an adult learning concept.The course is designed as a blended environment of presentation; workshops; group work; practical exercises; field application/ case studies, analysis and several industry videos showing all processes; and general discussions. The course will include real case studies in the oil and gas industry. Most of the cases studies have been presented in international journals by the instructor.

Pre & Post course assessments will be used to measure the effectiveness of this training and measure the skill and ability of participants.
