About this Training Course This intensive 5 full-day has been designed as a separately bookable course comprising 3 days of Well Integrity (Basic) and 2 days of Advanced Well Integrity. The intensive 3 full-day course will equip the participants with a thorough knowledge of well integrity management and risk assessment in producing assets. Based on the regulatory requirements and using real examples and exercises from around the world, this represents best practice integrity management within the oil and gas industry. When to take action with a well is a critical decision, both from a safety and economic perspective. A consistent approach to decision-making provides certainty within the organisation, focusing effort, and spending wisely. The decision-making steps will be set out to ensure all critical aspects are captured consistently. Risk analysis approaches used by different organisations and examples of risk management and risk-ranking methods will be discussed. The 2 full-day course will deepen the participants' knowledge of well integrity management, and skills for designing, operating, and maintaining well equipment. The ultimate goal is to optimise productivity at the lowest Unit Operating Cost (UOC) and to maintain mechanical integrity throughout well life cycle. Well Integrity management is looked at in three distinct stages. The first stage is during the well design which includes material selection, engineering design, cement design, coating and inhibitors and cathodic protection. The second stage is monitoring the well during the life of the well, locating possible leaks and / or loss of metal. The last stage is to manage and control any well integrity issues using specialised products, services and techniques. Training Objectives 1. Well Integrity Training: Upon completion of this course, the participants will be able to: Define the building blocks of a successful well integrity management system Develop an approach to risk management, understand risk analysis and methods applied across the industry How do we 'Make Wells Safer', learn about emerging technologies for well integrity problem diagnosis and new techniques available to 'repair' the issues Execute the basic elements of well integrity management training for field operators Evaluate well design elements that enhance or hinder well integrity status definition during the operating phase of the well life-cycle Gain the demonstrable benefits of well integrity management from field experience Review cases studies and discuss them to enhance knowledge and take on board lessons learned 2. Advanced Well Integrity: Define well integrity well categorization based on compliance to the barrier policy outlined in the regulations and develop an approach to risk management Discuss well-completion design and construction to create a 'integer' well with the lowest life cycle maintenance cost from a WIM perspective Monitoring and surveillance of well integrity, focusing on barrier competence such as cementing and corrosion Investigate and manage well integrity issues, causes & potential solutions Understand repairs needed to address 'Loss of Well Operating Envelope' Gain an overview understanding of Well Suspension & Well Abandonment Discuss further case studies as well as conduct a post course test Target Audience Invaluable for production, operations, and integrity professionals involved in implementing & managing well integrity and seeking to improve performance. It is also essential for those who need to develop and implement such systems, or who have a general need to know and understand more about well integrity management. The course will also provide a fresh approach for senior professionals and managers. Designed for professionals in the oil and gas industry who are involved in the design, construction and operation of wells from the following disciplines: Production Maintenance Production Operations Drilling Engineering Safety engineering Well Intervention Well Integrity Engineering Asset Management Course Level Intermediate Advanced Trainer Gordon Duncan has over 40 years of experience in the Oil & Gas industry. During that time, he has worked exclusively in well intervention and completions. After a number of years working for intervention service companies (completions, slickline & workovers), he joined Shell as a well service supervisor. He was responsible for the day-to-day supervision of all well intervention work on Shell's Persian/Arabian Gulf platforms. This included completion running, coil tubing, e-line, slickline, hydraulic workovers, well testing and stimulation operations. An office-based role as a senior well engineer followed. He was responsible for planning, programming and organising of all the well engineering and intervention work on a number of fields in the Middle East. He had a brief spell as a Site Representative for Santos in Australia before joining Petro-Canada as Completions Superintendent in Syria, then moved to Australia as Completions Operations Superintendent for Santos, before returning to Shell as Field Supervisor Completions and Well Interventions in Iraq where he carried out the first ever formal abandonment of a well in the Majnoon Field. While working on rotation, he regularly taught Completion Practices, Well Intervention, Well Integrity and Reporting & Planning courses all over the world. In 2014, he started to focus 100% on training and became the Technical Director for PetroEDGE. Since commencing delivering training courses in 2008, he has taught over 300 courses in 31 cities in 16 countries to in excess of 3,500 participants.

Enhancing Performance with Productive Conflict: In-House Training Most organizations have typically held the belief that workplace conflict is something that needs to be prevented, resolved, and/or mitigated. After all, conflict creates stress and leads to a variety of performance problems and very real costs. However, what savvy organizations have come to embrace is the understanding that when conflict is truly understood and harnessed, it can be utilized to not only add value to teams, but also enhance workplace performance. Conflict can be productive and make organizations better! Learners will explore the results of a formal, personalized, conflict-related assessment, uncovering targeted nuances of their conflict responses in action. Participants will learn to use basic strategies which allow them to transform destructive conflict responses into more productive ones, especially in the moment when they are happening. What you will Learn At the end of this program, you will be able to: Apply different models for understanding the lifecycle and dynamics of conflict Describe a physiological response to conflict and its impact on communication Recognize the correlation between a person's conflict style and how they respond to conflict Identify your own default responses to conflict and catch them in action Reframe automatic negative thoughts to create more positive interpersonal outcomes Utilize various tactics and strategies to transform destructive conflict responses into productive ones Getting Started Introductions and social agreements Course goal and objectives Opening activities Module 1: The Dynamics and Anatomy of Conflict Conflict basics Dynamics of conflict The anatomy of conflict Module 2: Conflict Styles and Conflict Conflict through the conflict style lens Exploring your style in conflict Destructive responses to conflict Module 3: Changing Your Response to Conflict Changing your conflict response Three steps to productive conflict Choosing a productive conflict response
