About this training Mature fields differ from green field developments in that major infrastructure is in place, static reservoir data has accumulated from development drilling and a growing volume of production and processing performance data has become available. Decisions therefore relate to incremental projects, which may be small in scope and are often economically marginal. A firm understanding of the technical fundamentals associated with reservoir, wells and surface facilities is therefore required to make quality decisions in this environment, supported by realistic uncertainty ranges, and consistent application of incremental project economics and risk analysis. Various strategies may be considered to manage the mature asset, from harvest to divest, and the selected incremental activities should support a clear chosen strategy. Training Objectives Upon completion of this course, participants will be able to: Characterize the overall challenges associated with mature field developments Evaluate critical insights from subsurface data and apply this to modelling options and recovery methods Assess associated well data, typical late life issues and drilling and completion options for mature developments Manage the role of risk and uncertainty when making mature field development planning decisions Prepare a strategy and implementation plan Target Audience The course is intended for individuals who play a part in evaluating, screening and maturing oil and gas field development opportunities. The following personnel will benefit from the knowledge shared in this course: Petroleum engineers Geoscientist Facilities engineers Commercial staffs Reservoir engineer Production engineer Drilling engineer Project manager Asset manager Field engineer Exploration manager Course Level Basic or Foundation Trainer Your expert course leader, boasts nearly four decades of experience in the upstream oil & gas industry. He began his career in the back in 1982, spending 13 years with Shell International across several global locations. During his tenure, he served primarily as a reservoir engineer, contributing to exploration prospect evaluation, field development planning, corporate business planning, and drilling operations. Throughout his career, he has executed a diverse range of reservoir engineering projects for multiple UK and international firms, and has successfully led several PE study teams. Furthermore, he has continuously provided reservoir engineering and commercial training to oil company staff on a national and international scale.

About this Training Course Time is money in all industries. For the Oil & Gas industry, this is no exception and the ability to maximise return on investment is all related to where the Oil is and how easily and quickly we can get that product to the customer. Whether in a technical, managerial or supporting role, you are a valuable asset in ensuring that project delivery targets are met and profits are realised. As Petroleum Engineering (PE) activities continue to increase, professionals like you must grasp the language and technology of PE operations in order to maximise expenditures throughout the producing life of a well. Petroleum Engineering equipment and procedures have a unique language that must be conquered for maximum benefit. Clear and understandable explanations of rig equipment, completion equipment, operations procedures, and their complex interactions provide an excellent foundation for smooth communication and increased efficiency in inter-department project team efforts. A confident understanding of the technical jargon and a visual appreciation of the various pieces of equipment used provides for an overall 'big picture' of the industry value chain. This serves as an excellent foundation for smooth communication and increased efficiency in inter-department project team efforts. This course can also be offered through Virtual Instructor Led Training (VILT) format. Training Objectives By the end of this course, the participants will be able to: Define the role of Petroleum Engineering and its interaction between other departments Describe terms used in the Oil & Gas industry such as Surface/Subsurface, Upstream, Midstream and Downstream Describe the Appraisal of Oil & Gas Discoveries, the Cost Estimations, Economics & Reserves Explain what is the Formation, how do we connect to it, and how do we ensure best value Describe how to construct a well, select the equipment & methods, understand the duration that the well is required to perform for Target Audience This course will benefit those in geology, reservoir engineering, equipment and maintenance, and non-petroleum engineering technical professionals as well as forward-looking executives in the following fields who are interested to enhance their knowledge and awareness of the drilling process for increased productivity and contribution to the team that they're supporting: Accounting Administration Business Development Commercial E & P IT Estimation & Proposal Finance & Administration Finance HSE General Management Joint Ventures Legal Logistics Materials Planning Planning & Budgeting Procurement Sourcing Supply Chain Tender Contract Training Drilling Fluids Course Level Basic or Foundation Trainer Your Expert Course Trainer 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.
