About this Training Course  The prospect maturation process, from a lead to a drillable prospect, is at the heart of the exploration business. This 5 full day course will cover all aspects of the prospect maturation process: play understanding in the context of regional geological understanding, detailed prospect evaluation; realistic risk & volume assessment consistent with the play understanding and prospect details, and an introduction to exploration economics. Throughout the course, there is a strong focus on pragmatic (geo)logical approach for assessing those aspects that are input parameters for a meaningful assessment of prospect risks and volumes, with emphasis on a balanced integration of contributions from different sub-surface disciplines. Many examples from basins from around the world are used to illustrate how traps, reservoirs, seals and charge occur in different basin settings. Specifics topics that will be discussed include the following: The statistical fundamentals for risk and volume assessment will be presented, with practical exercises for understanding the results of a risk & volume assessment as they are displayed in expectation curves. The difference between risk and uncertainty. A full discussion of the essential requirements for a working petroleum system: Trap, reservoir, seal and charge. Examples of how traps, reservoirs, seals and charge work in different basin types around the globe and in Australian basins. Exercises and guidelines for estimating uncertainties for prospect parameters, including advice for deciding which distribution type to use, and how to constrain those distributions for meaningful uncertainty ranges (setting minimum most likely and maximum values). Particular emphasis will be given to estimating hydrocarbon column lengths with their associated uncertainties in undrilled prospects. Prospects and plays: The value of play maps and how these should be used for assessment of prospect risks and for ranking of prospects within a play. Calculating volume ranges for prospects. Calculating volumes for groups of prospects; how to add risked prospect volumes for a statistically correct representation of the volume promise of a portfolio of prospects. Geophysical evidence: Incorporating geophysical evidence (DHIs) consistently and realistically in a risk assessment. An understandable and geology-based workflow, consistent with Bayes theorem, will be presented. Exploration economics. Training Objectives What this course will cover in 5 days: This course describes the various aspects that need to be considered in the prospect maturation process, including: Play development in the context of a sound understanding of the regional geology Detailed prospect evaluation and understanding of the critical aspects of traps, reservoirs, seals and charge Examples from plays and prospects in different basin settings from around the globe Realistic and pragmatic risk and volume assessment, based on the geological understanding of plays and prospects An introduction to exploration economics Examples of plays, oil and gas fields and prospects from basins from around the world, including the Far East, will be given. Target Audience This course is designed primarily for Geoscientists in exploration who would like to improve their expertise of the prospect maturation process and risk and volume assessment. The course has proven to be of value for explorers in the early phase of their career, seasoned explorers and team leaders. It will also benefit staff from disciplines working closely with exploration staff including Prospect Portfolio Analysts, Petrophysicists, Geophysicists and Reservoir Engineers. Course Level Intermediate Training Methods At the end of the course, the participants will have a good understanding of the essentials for realistic risk and volume assessments of exploration prospects. The course should allow participants to produce well-considered and realistic assessments for prospects they may be working on, and to understand and constructively challenge risk and volume assessments of colleagues and/ or partners/ competitors. Each topic is introduced by a lecture, and learning is re-inforced by practical exercises and discussions. Hand-out materials in paper and/or electronic format will be provided. Time will be made available to discuss aspects of prospects that may be brought in by course participants. Trainer Your expert course leader has a PhD in Geology from the University of Utrecht.

About this Training Course This 5 full-day course is aimed at engineers and supervisors who already have a basic understanding of well construction methods but who would benefit from a more detailed knowledge of completion design. The course will concentrate on the important aspects of completion design and what makes a safe and efficient well. A common thread of practical examples will be used throughout the course in the form of a case study or 'red-thread' exercise. The case study is based around data all taken from a single field where those attending will work through all the basic issues of a completion design. The exercises associated with the case study is performed in the student's own time after each of the formal sessions. However, at the start of the next day, the case study is reviewed and discussed. The whole case study will continue through all sessions, with each element being reviewed at the start of the next session. There is no 'right' answer to the exercise - producing interesting discussions! The purpose of the course is not to go over specific equipment in detail. Teaching methods include presentations, videos, and animations and the case study. The course will cover: Types and configurations of completions The completion design process Inflow performance, skin and formation damage Perforating; selection, deployment and interface with rest of completion Stimulation and impact on completion and flow performance with coverage of modern horizontal multifrac tools Open hole, non-sand control completions including open hole packers and horizontal well clean up Sand control; when do you need it, basic types and selection guidelines. Includes standalone screens, ICDs, various gravel packing techniques, frac packs and expandable screens Tubing sizing, flow estimation and liquid loading Artificial lift; types and selection criteria, interface with drilling, reservoir and facilities. Design of gas lift and ESPs included Production chemistry impacts on completion, prevention and removal (scales, wax, asphaltene, hydrates, and souring) Metallurgy, corrosion, and erosion; metal types and selection of Elastomers and plastics; types and selection of Tubing stress analysis; picking the grade and weight of tubing, plus selection criteria for packers and expansion devices. Interface between tubing stress analysis and casing design Completion equipment; basic types of equipment, reliability and selection criteria for each (tree, safety valve, mandrel, packers, expansion devices etc) Completion installation; importance of wellbore clean-out, function and types of brines, pointers for efficient completion installation Non-conventional wells; types and when / where to use them (multilaterals, smart (intelligent) wells and also SAGD, CO2 sequestration, CBM, etc) Training Objectives By the end of this course, the participants should be able to: Have a good understanding of the completion design process and what makes a good completion design Understand the importance of the installation process (completion running) in the design process Have an appreciation of new and developing completion techniques (intelligent wells) Target Audience This course will benefit engineers and field-based personnel such as completion supervisors and production engineers. It is also suitable for completion vendors, specialists such as chemists and subsurface personnel including geologists, reservoir engineers and petrophysicists. Trainer Your expert course leader has 30 years of oil and gas industry experience. A first class degree in geophysics and a master degree in Petroleum Engineering was a prelude to seven years with BP as a petroleum engineer.
