TOLES Foundation Certificate in Legal English Skills Why Attend Legal English is a different language from general English. Just as lawyers in any particular country write in a different language from other people in that country, so do English lawyers. Sentences are often structured differently in legal English. The words lawyers use are often centuries old and no longer commonly used in general English. New prepositions must be learned and practiced. When reading a commercial contract or a letter, there is new technical vocabulary to understand on every page. This course is designed to look at authentic rather than artificial legal context. For this reason, there is a strong focus upon practical and authentic tasks, and upon candidates having a good grasp of terminology from the outset. The course takes account of significant language reforms in the English legal system and the legal profession's continued movement towards clearer use of English as recommended on Legal Practice courses at all major UK universities and legal training centers. The Test of English Legal English Skills (TOLES) governing body is a member of the International Division of the Law Society of England and Wales. Multi-national companies such as Allen & Overy LLP, Baker and McKenzie, PWC, KPMG, Sony Ericsson, European Court of Justice, European Central Bank and many more use TOLES training and exams to prepare their law professionals whose first language is not English for the international legal challenges. On the final day of the course, participants will take their TOLES Exam to earn the TOLES Foundation Certificate in Legal English Skills. Course Methodology The course consists of group discussions as well as individual and team tasks. There will be writing exercises and practice exams at the end of each day, culminating in sitting the TOLES Foundation Exam on the final day of the course. Course Objectives By the end of the course, participants will be able to: Apply correct legal vocabulary when communicating with clients/law professionals and will be familiar with modern legal writing style Recognize common mistakes in English and will be able to identify accurate prepositions and collocations within a legal context, particularly within the context of written contracts Differentiate between the English legal system and the American legal system Recognize improvements in their reading and comprehension skills of legal documents and demonstrate accurate written solutions within a legal context Target Audience This course is useful for law and legal professionals, translators, contract assistants and managers who already possess good general English and are now acquiring legal vocabulary, as well as those who are required to obtain a TOLES certification by their organization. Target Competencies Legal vocabulary and grammar Legal communication Legal comprehension skills Formal written contracts Note The Test of English Legal English Skills (TOLES) governing body is a member of the International Division of the Law Society of England and Wales. Multi-national companies such as Allen & Overy LLP, Baker and McKenzie, PWC, KPMG, Sony Ericsson, European Court of Justice, European Central Bank and many more use TOLES training and exams to prepare their law professionals whose first language is not English for the international legal challenges. The TOLES Foundation level exam tests Legal reading and writing. The focus of the exam is on testing the absolute linguistic accuracy required of lawyers in a modern international office. This means accuracy in two main areas: technical legal vocabulary, and grammar. Vocabulary from commercial deals, company documents, commercial contracts, intellectual property agreements, financial documents and forms of business are tested, as well as legal terminology from other areas.

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.

About this training course Gas well performance is dictated by the combination of inflow and outflow performance. The outflow performance of any gas well is at risk as soon as the gas rate becomes insufficient to lift the associated liquid water and condensate to surface. This condition is referred to as liquid loading and invariably causes intermittent production and significant loss of well capacity and reserves. Liquid loading can be mitigated by different types of gas well deliquification such as compression, velocity string, plunger lift, foam-assisted lift, gas lift and downhole pump. This 5 full-day course will first show how to predict and recognize liquid loading. Next, it will describe how to select, design, install and operate the best sequence of deliquification measures. It will also consider deliquification in the presence of other production threats such as water production and halite blockage. These topics will be illustrated by an abundance of field examples and case studies. The participants will be completing a case study during the training. This case study is preferably based on their own relevant data set. If no such data is available, an external data set will be provided instead. Prerequisites skills: It is necessary for the participants to have a basic knowledge of petroleum engineering and gas well performance. This course can also be offered through Virtual Instructor Led Training (VILT) format. Training Objectives On completion of this course, the participants will be able to: Develop skills and tools to understand and model gas well liquid loading and deliquification Understand the principles and practicalities of different deliquification methods Learn how to compare, select and apply deliquification measures by taking own field case as example Target Audience This course is intended for production engineer, surveillance engineer, completion engineer, production/process chemist, reservoir engineer, production programmer, production operator as well as professionals responsible for selecting, installing, operating, monitoring and optimizing deliquification. Course Level Basic or Foundation Training Methods This course utilizes Excel worksheets first introduced in the Optimising Gas Well Performance course. To derive maximum learning value, the participants are requested to bring their own relevant set of field data to complete their own case study during the training. The list of data required will be shared beforehand so data can be timely collected and cleared for external use. The participants should be prepared to complete any unfinished exercises and assignments before next day's session starts. The instructor will be available to discuss any remaining queries after the completion of the course.
