The process of drilling an oil and gas well will be outlined. We will look at the surface equipment, downhole technologies and associated safety issues. Drilling fluids, casing and cementing the well, directional drilling etc. will be investigated
|Second Sub Session
|15 credits (7.5 ECTS credits)
The course provides students with an overview of rotary drilling system and associated drilling components. The types, selection and characteristics of drilling fluids are discussed, and the analysis of the flow of drilling fluids during drilling is presented. Strategies for the selection and design of casings, cementing methodologies as well as design and configuration of completion systems are introduced, with emphasis on safety implications. Challenges of directional and horizontal drilling methods and associated technologies are discussed. Students will learn the common issues in drilling operations, including drilling remediation and environmental impact and considerations.
Information on contact teaching time is available from the course guide.
1st Attempt: 1 three-hour written examination paper (80%), continuous assessment (20%). The continuous assessment will comprise of laboratory practical on drilling fluids and a piece of written work consisting of a case study. Resit: 1 three-hour written examination paper (80%), continuous assessment (20%). In case of noncompletion or failure of the laboratory portion of the continuous assessment, stundents will be able to submit an equivalent written assignment.
Weekly tutorial question sheets covering core concepts in course.
