Introduction to Offshore Drilling

Course background More than one-third of oil and gas currently comes from offshore producing fields. This is increasing as the search for hydrocarbons extends into more remote offshore environments. In fact deepwater activity is the fastest offshore growth sector. As offshore drilling is central to many companies development and may represent 25 to 40% of the total company spend, and with new deepwater fields often exceeding 20-50-100 wells. With rig day rates at historic highs it is therefore essential to deliver safer, more effective, and cost efficient drilling of wells through the use of adaptive technological equipment, systems and processes. This course provides a comprehensive introductory explanation of offshore drilling through typical field life cycle processes. All offshore drilling rig and equipment systems components are explained in detail, as well as methods of rig moving, mooring and positioning, all drilling operating activities from the start to the suspension and abandonment of wells. Issues of key drilling problems, health safety environment, loss, waste control management and blowout prevention are also covered. Finally, new drilling techniques, adaptive approaches and highly mechanised and automated rigs are discussed, supported by examples, illustration and case studies from field developments around the world. The knowledge and experience of all contributors explain the necessary hardware involved in offshore drilling, how it is implemented from exploration, appraisal and development to deliver the drilling of offshore oil and gas wells. It will benefit anyone involved or requiring an introduction to Offshore drilling operations; those new to the field seeking an introduction to key equipment and terminologies; or non-technical professionals in the oil and gas or associated industry’s desiring an overview to the knowledge, experience, engineering, technologies, best practices and principles to deliver offshore drilling projects. The course material available is up-to-date, offering recent practical hands on knowledge and experiences from practising drilling professionals, and suitably illustrated with case studies, images and diagrams. Course overview The course illustrates the critical role drilling provides in the expanding offshore oil and gas sector. Offshore drilling hardware, technologies, rig equipment and systems components are explained in the context of offshore exploration, appraisal and development drilling.
