About this Training Course Comprising 5 full-day sessions, this intermediate to advanced level course is specifically designed for senior exploration geoscientists currently active in hydrocarbon play and prospect mapping, to optimise conceptual geological input into their technical evaluation. The course focuses on seismic stratigraphic analysis in different basin settings - i.e., passive, convergent, extension and oblique - in order to construct a coherent geological story line, underpinning hydrocarbon play and prospect evaluation. The course is largely based on seismic stratigraphic case histories and exercises, with the support of seismic, well log and outcrop examples. Training Objectives Through short, focused presentations and a series of industry case history-based examples and exercises, participants will learn to optimise conceptual geoscience input into technical subsurface analysis. This will help to produce coherent geological subsurface interpretations for use in Play-based, Prospect and Appraisal evaluations. Target Audience This course is intended for senior geoscientists with more than five years of work experience, with a background in play and/or prospect evaluation and experience in seismic interpretation. Course Level Intermediate Advanced Training Methods Participants will be exposed to short lectures throughout the 5 days, followed by hands-on individual and team exercises in a variety of geological settings. 'Let the data tell their story' is a key recurring theme in this course.

About this Training Course Well interventions have a large opportunity to enhance well production if correctly designed and implemented. Conversely, they can have a large negative impact on production if they're not. The Well Intervention & Productivity School (WIPS) is designed to help well intervention specialists, well service supervisors, and petroleum engineers become more aware of the problems that can arise in the planning and execution of well interventions. This 5 full-day course is designed to make those that attend aware of how their job can directly impact the productivity. Early identification of problems in wells and effective interventions to fix problems can have a significant impact by minimising lost oil through formation damage and non productive time. As well as discussing best practice, time will be made available for discussion relating to specific problems that may be affecting fields operated by members of the class. The course is a mixture of informal teaching and lectures. In addition, group exercises are used to reinforce the subjects covered during the lectures. This encourages cross discipline awareness, communication and motivates team building. The course has recently been updated in the areas of Subsea and HPHT interventions. This course can also be offered through Virtual Instructor Led Training (VILT) format. Training Objectives Upon completion of this course, the participants will be able to: Identify the main reasons for performing well interventions. Identify the main formation damage mechanisms and understand how to prevent them. Improve your knowledge and understanding of well barriers. Improve your knowledge of pumping and stimulation operations. Improve your knowledge of wireline, coiled tubing and hydraulic workover operations. Target Audience The course is aimed at all engineers and contractors involved in the planning and execution of well interventions. This is a school where engineers and supervisors can hone their skills, especially at a time when increased production is a high priority. In the past, course attendees have been a mix of Petroleum engineers, Well Intervention engineers, Reservoir and Drilling engineers, Production Operators, Wellsite supervisors, as well as Geologists. In recent years, delegates have come from a wide range of disciplines and backgrounds. Experience before coming on the course has varied from no field experience and no experience of planning and programming well interventions through to many years working in well interventions. In order to be able to best adapt the course to the delegates expectations, you will be required to submit a pre-course questionnaire upon submission of your registration. Course Level Intermediate Trainer Your expert course leader has over 40 years in the oil industry. During that time, he has worked exclusively in well intervention and completions. After a number of years working for intervention service companies (mostly slickline), he joined BP as an offshore well service supervisor. He was responsible for the day-to-day supervision of well intervention work on many of BP's North Sea platforms and subsea wells. This included coil tubing, e-line, slickline, stimulation and well test operations. An office-based role as a well operations engineer followed. He was responsible for planning, programming and organising of all the well intervention work on the Bruce and later the Magnus fields. In 1995, he moved into completion design. Since then, he has designed many platform and sub-sea completions, often travelling to the rig site to oversee the installation. In addition to his day-to-day work as a completion engineer, he regularly teaches completion and well intervention courses all over the world. He is also the author of the book, Well Control for Completions and Interventions, Gulf Publishing - April 2018. He has also appeared as an expert witness ant the International Court of Arbitration.   POST TRAINING COACHING SUPPORT (OPTIONAL) To further optimise your learning experience from our courses, we also offer individualized 'One to One' coaching support for 2 hours post training.
