1 Month Summer Internship Program
About This Course
Reservoir, drilling, well completion, well Intervention and Well integrity
Oilwell Drilling introduces the techniques and technologies involved in drilling oil wells. The course is intended for personnel new to the oil and gas industry, specifically including those in the administrative and support services as well as those in the field. Oilwell Drilling provides a firm foundation knowledge of oilfield practices and terminology that can prove invaluable in every sector of the industry.
Reservoir engineering is a branch of petroleum engineering that applies scientific principles to the fluid flow through porous medium during the development and production of oil and gas reservoirs to obtain a high economic recovery. The study of reservoir engineering is of the utmost importance, since we cannot go to design the construction of an oil well without first having gathered all the geological information such as electrical registers, pressure registers, among others.
A well intervention is any operation carried out on oil or gas well during its productive life that alters the state of the well, provides well diagnostics, or manages the production of the well.
This course will contain in-depth information on the impact of workovers and completion design in maximizing field production and increasing recoverable reserves. It also emphasizes the importance of well interventions methods during lifetime of the well to keep well productivity under optimum conditions.
This course also covers acceptable planning, techniques, and equipment for completion and stimulation of newly cased wells. Also covers planning, organizing, and supervising remedial and recompletion operations on old wells. This course emphasizes the role of engineers and field operators in planning and executing the Intervention Operations to maintain and increase field production and thus add to the profitability and recoverable reserves.
The course is highlighted with open discussions and problem solving shared by the instructor and participants.
The Objective of the Internship is to introduce the concepts of well construction & interventions which can help in optimizing the Oil and Gas Well’s Life Cycle.
- First part of the course will help the attendees to understand various reservoir concepts from scratch.
- Second part is focused on drilling & well engineering concepts. Different drilling topics will be discussed to offer learners a better grasp of how to drill a well.
- Last part will help to understand the design philosophy, equipment, and resources (tools and consumables) used in completing the oil well along with the recommended operational sequence typically followed by the industry.
Course Duration: 1 Month
