Emotional Intelligence Training

About this Training Course Time is money in the oil business. Drilling time is big money. Whether in a technical, managerial or supporting role, you are a valuable asset to ensuring that project delivery targets are met and profits are realised. As drilling activities continue, professionals like you must grasp the language and technology of drilling operations in order to maximise expenditures throughout the producing life of a well. Drilling equipment and procedures have a unique language that must be conquered for maximum benefit. Clear and understandable explanations of drilling rig equipment, procedures, and their complex interactions provide an excellent foundation for smooth communication and increased efficiency in inter-department project team efforts. Drilling Essentials will help you de-mystify activities around the rig and well planning. It will explain the fundamentals of drilling with an emphasis on key areas such as logistical considerations, costing, and analysis of drilling contracts. Understand the urgency of drilling requests, know more about the cost implications of drilling-related problems, and understand the risks involved in a drilling contract. With the course director's drilling knowledge and skills, this is your opportunity to explore and understand important drilling concepts, principles, and technology which are presented in a reader-friendly format and illustrated with examples. As a non-drilling professional, you too can grow with the drilling industry with a deeper understanding of the critical role you play in contributing to its success! Training Objectives By attending this industry fundamentals Virtual Instructor Led Training (VILT) course, you will be better able to: Understand drilling terminology & drilling processes for completing onshore & offshore wells Appreciate major cost components of drilling operations and its impact for better project planning and management Better visualise major drilling equipment and their technical functions to promote a deeper understanding of the logistical and technical considerations Gain valuable insights on the drilling industry with a synopsis of recent technology developments that impact the drilling process Target Audience This Virtual Instructor Led Training (VILT) course has been developed for new engineers and forward-looking executives in the following fields who are interested in enhancing their knowledge and awareness of the drilling process for increased productivity & contribution to the team they're supporting: Accounting Commercial Finance & Administration General Management Logistics Procurement Tender Contract Administration E & P IT Finance Joint Ventures Materials Planning Sourcing Training Business Development Estimation & Proposal HSE Legal Planning & Budgeting Supply Chain Drilling Fluids Organisational Impact 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.

This is a practical ‘non medical’ day for front line practitioners working with children and young people with serious attachment issues arising from loss, trauma and abuse. We look at what Psychology may help us in our understanding of children who have faced issues with love and attachment. Splitting, handling projected feelings, constancy and permanence are explored. Online Course now available via Teachable Platform – Understanding Attachment Learn at your own pace… lots of text and video support Course Category Meeting emotional needs Behaviour and Relationships Inclusion Teaching and Learning Description This is a practical ‘non medical’ day for front line practitioners working with children and young people with serious attachment issues arising from loss, trauma and abuse. Drawing from the international research and literature and our own experience over many years as educational psychologists of the challenges of children with major social and emotional needs, we will explore together what the best practice can and could look like. We explore the language of attachment and outline very practical classroom strategies. We look at what Psychology may help us in our understanding of children who have faced issues with love and attachment. We explore the feelings of being on a desolate island of relational poverty or to imagine swimming with sharks. We explore the themes of violence, anxiety and experience of being a victim as young people grow older. We look at telling lies and explore how we can respectfully understand this. We reveal the new and innovative compass of vulnerability – the cognitive errors to which some are much more vulnerable. We look at triggers, self regulation and unpack a range of strategies.  Transference and counter transference are examined along with splitting, handling projected feelings, constancy and permanence. We explore what young people with these difficulties really need from us. We also spend time looking at the emotional impact on practitioners working with children with such needs and what helps at an personal and team level. We can all do something – we do not have to wait for expert therapists to arrive!  Testimonials Very moving presentation I will always try and think behind the behaviour now It had a huge impact on all levels We all seem to need it Belonging and feelings are so important Very user friendly Excellent! Learning Objectives Increased confidence regarding developing inclusive practice for children with serious attachment needs in mainstream schools Simple understandable explanation of attachment understood Access to a wider range of practical strategies to impact on social and behavioural needs Deeper understanding of core values surrounding inclusion of emotionally disabled children Opportunity to reflect on professional attitudes and behaviour towards parents and pupils with complex emotional needs New skills, scripts and processes to make inclusion successful Who Is It For ? Practitioners working in schools and other settings with children and young people of all ages Key workers Teaching Assistants with support roles Heads and deputies SENCOs Advanced skills teachers Primary and secondary classroom teachers Parents Local authority support services Course Content The course explores the questions : How can we start to develop an understanding of children with attachment needs? What is the true impact of loss, trauma and abuse? What else can we do to go about including high profile children or young people with challenging emotional needs? What useful psychological constructs can we use to guide us? This course also explores practical strategies and language for key adults rebuilding relationships with individual pupils. This is a participative day that aims to be explorative and practical. Opportunities to develop empathy with the children of concern will be created.
