Course Overview

Decommissioning of offshore oil and gas  infrastructure requires graduates to have a competent and realistic understanding of well plugging and abandonment. This course allows students to understand the scientific, engineering, and economic rationale for abandoning wells and decommissioning fields.

Course Description

The aim of the course is to give students an overview of the origins of petroleum, factors influencing commerciality of fields, and the technical and economic need for decommissioning.  Students will gain practical understanding of the main technologies and procedures involved in the plugging and abandonment of oil and gas wells prior to decommissioning. The key aspects of specific regulatory and legislative drivers are also covered to provide the basis for the plugging and abandonment procedure.

This course examines different methods for well plugging and abandonment (P&A).  A general overview of reservoir and petroleum geology is presented with emphasis on depleted reservoirs and associated challenges for P&A.  Specific regulations set by regional and national governments  of well plugging and abondonment are discussed.  A detailed discussion is provided of the different methods for well plugging and abandonment, and associated technologies.  The application and limitations of materials such as cement slurries, gelled pills, mechanical plugs, inflatable plugs and sand plug are discussed, focusing on installation procedures and reliability and long-term (decadal) monitoring of well integrity.  Project planning and P&A implementation costs are examined.  Real-life case studies are used to support student learning.
