About this training course This 3-days training will provide a comprehensive review of integrity of wells exposed to carbon dioxide (CO2) in the context of Carbon Capture Utilization for enhanced oil recovery and Storage (CCUS). CO2 geological storage is a proven technology to reduce greenhouse gas emissions from sources such as coal power plants, cement kilns and steel mills. Wells are widely considered the most critical containment element, especially older wells that are not used to inject CO2 or monitor the plume evolution in the storage reservoir. The main reason for this perceived risk is the high corrosion rate of carbon steel when exposed to wet CO2, and the tendency of Portland cement to react with the gas. The training course advanced contents build on 15 years' experience in carbon storage, both in the development and deployment of technologies. First-hand, in-depth knowledge of the subject will allow us to debunk myths and focus on the real challenges of wells encountering CO2. Training Objectives After the completion of this training course, participants will be able to: Explain the CCUS market drivers Examine the behavior of CO2, on surface and in the reservoir Diagnose cement defects and design repairs Understand the limits of Portland cement Assess the benefits of different technologies and materials Realize why geology is a dominant factor in cement performance Critically choose the most appropriate monitoring techniques Classify aging processes of cement, steel, and rock when exposed to CO2 Assess the risk of existing wells if they encounter the CO2 plume Examine recent advances in real-time approaches to the production monitoring and lift management Target Audience This training course is suitable and will greatly benefit: All surface technical personnel such as process engineers & technologists Facility engineers, production engineers & technologists Drilling engineers and Well engineers Design engineers and Integrity engineers P&A engineers and Cementing engineers Geologists Senior management executives will benefit from this training as covers an overview of the technical and commercial details of CO2 capture technologies and risks involved. Course Level Intermediate Training Methods The training instructor relies on a highly interactive training method to enhance the learning process. This method ensures that all participants gain a complete understanding of all the topics covered.

About this Training Course Well engineers who are responsible for technically evaluating and authorizing programs for drilling or working over wells must have the required skills and competencies to safely design wells of varying nature. They also need to be able to confirm that well delivery and intervention programs generate intrinsic well control assurance. Such work programs must establish, verify, monitor and maintain suitable and sufficient barriers for the entire well lifecycle - from spud to abandonment. Well engineers must also be able to select a suitable drilling or workover rig, capable of safely performing the work within its operational envelope. This 3 full-day course aims to further develop and assess the knowledge required to work on and eventually, authorize a well delivery program as deemed fit for purpose. It also addresses elements of well control that must be embedded into well design, well work programming and equipment selection. This course is intended for participants who already have a sound understanding of the principles of the design and/or delivery of wells and with more than 3 years of relevant industry experience. Training Objectives By the end of this course, participants will be able to: Feel confident to design and plan drilling and workover activities while considering geological risks, formation pressures/strengths, and any integrity or well control concerns. Monitor wells operations and ensure that they can and will remain within the accepted design envelope. Assess risks and then apply mitigation or recovery methods in cases where design envelopes are threatened. Participants should be capable of assessing a drilling or workover program and then be able to answer the following key questions: Does the program delivery have a sound design and work plan that allows the well(s) to be drilled or worked over safely? Have we determined the appropriate kick tolerance for each open hole section and is it realistic for all drilling hazards that may be encountered? Have all drilling hazards been suitably assessed, and the associated risk mitigated to a level as low as reasonably practicable? Are there adequate, verifiable barriers in place throughout the operation and does everybody know their role and responsibility? And, as applicable, is the selected rig capable of implementing the work program? Target Audience This course is intended for personnel directly or indirectly involved in the preparation, review or authorization of drilling and workover programs. This includes: Well engineers and drilling supervisors who are responsible for planning and executing drilling and workover operations. Contractor well engineers, rig managers and other senior drilling staff. Senior well engineers and rig superintendents who are responsible for managing the delivery of a project or well. Technical authority holders who are responsible for licensing drilling and workover operations from a regulatory perspective. Assessment: A satisfactory command of critical knowledge and skills is assured by a 1+ hour closed book assessment. This assessment has a mix of multiple-choice questions (MCQs), calculations and answers that must be written up. The exam is taken electronically. Participants are provided with a suitable formula sheet. The pass mark for issuing a certificate is 70% and participants who are not successful will be issued with a certificate of attendance instead. Trainer Your expert course leader has over 45 years of experience in the Oil & Gas industry. During that time, he has worked exclusively in the well engineering domain. After being employed in 1974 by Shell, one of the major oil & gas producing operators, he worked as an apprentice on drilling rigs in the Netherlands. After a year, he was sent for his first international assignment to the Sultanate of Oman where he climbed up the career ladder from Assistant Driller, to Driller, to wellsite Petroleum Engineer and eventually on-site Drilling Supervisor, actively engaged in the drilling of development and exploration wells in almost every corner of this vast desert area. At that time, drilling techniques were fairly basic and safety was just a buzz word, but such a situation propels learning and the fruits of 'doing-the-basics' are still reaped today when standing in front of a class. After some seven years in the Middle East, a series of other international assignments followed in places like the United Kingdom, Indonesia, Turkey, Denmark, China, Malaysia, and Russia. Apart from on-site drilling supervisory jobs on various types of drilling rigs (such as helicopter rigs) and working environments (such as jungle and artic), he was also assigned to research, to projects and to the company's learning centre. In research, he was responsible for promoting directional drilling and surveying and advised on the first horizontal wells being drilled, in projects, he was responsible for a high pressure drilling campaign in Nigeria while in the learning centre, he looked after the development of new engineers joining the company after graduating from university. He was also involved in international well control certification and served as chairman for a period of three years. In the last years of his active career, he worked again in China as a staff development manager, a position he nurtured because he was able to pass on his knowledge to a vast number of new employees once again. After retiring in 2015, he has delivered well engineering related courses in Australia, Indonesia, Brunei, Malaysia, China, South Korea, Thailand, India, Dubai, Qatar, Kuwait, The Netherlands, and the United States. The training he provides includes well control to obtain certification in drilling and well intervention, extended reach drilling, high pressure-high temperature drilling, stuck pipe prevention and a number of other ad-hoc courses. He thoroughly enjoys training and is keen to continue taking classes as an instructor for some time to come.
