Course description

This course on well test analysis will provide attendees with a basic knowledge on the subject. The course will start with a review of an oilfield life from exploration, appraisal, development and abandonment to define the role of well testing. The history and clear definition of the subject will also be given as an introduction summary.

The course will cover classic, modern and numerical well testing concepts and techniques, where selected synthetic and field examples will be used throughout the course to demonstrate these concepts and application procedures.

The information given on the course is the distillation of the instructor’s over 16 years experiences on the subject in teaching, research and practice (consultancy in the oil industry).

 

Course objectives

This one-day course was designed for reservoir engineers, production engineers, geologists, geophysicists and petrophysicists in order to master the basic theory and skills in well testing. This is an ideal introduction on the subject for those who knew nothing about this field before also beneficial as a knowledge update for those who have experience in well testing.

 

Course outline

Classic well testing

  • The course will also include: the principal of stabilized well (production) testing and un-stabilized/transient well testing (pressure draw down and build up). Concepts such as well damage skin factor; well bore storage; effective well bore radius and radius of investigation will also be introduced.
  • Flow through porous media; pressure draw down solution and analysis; principle of superposition; pressure build-up solution and analysis.

Modern well testing

  • As the introduction of modern well test analysis, logarithmic pressure derivative; diagnostic method and type curve matching will be covered. Double porosity and double permeability reservoir behaviors will be introduced to demonstrate the application of the diagnostic processes.

Numerical well testing

  • Numerical well test concept will be given and demonstrated through published synthetic and field examples.

Field case studies

  • Selected filed examples will be used during this one day course to demonstrate the analysis procedures and the application of the derived solutions.

 

Participants' profile

This course is aimed at reservoir engineers, production engineers, geologists, geophysicists and petrophysicists.

 

Prerequisites

Participants would benefit from prior knowledge on well testing but this is not essential.

 

About the instructor

The instructor has 29 years experiences in the oil industry and academic institutions (teaching and research). As a senior member of SPE and EAGE, he was the head of well testing Group and a Senior Lecturer on the subject in the Institute of Petroleum Engineering (IPE) at Heriot-Watt University, where He taught MSc well testing course in China (China University of Petroleum, CUP), Malaysia (University Technology of Petronas, UTP), Edinburgh Scotland and Dubai for over 300 MSc students annually from 2005 -2010.

At the same time, he taught and graduated 90 students with Heriot-Watt MSc Degree in CUP China from 2005 — 2008 as the Course Director. He was the well testing research project manager (PRIME Project) at Heriot-Watt, with which he graduated three PhD students and won the industry funding for current four PhD students still working on the subject areas of well testing.

He was the well testing short course instructor for SPWLA in 2008, SPE Asia Pacific Co-Chair for the SPE Applied Technology Workshop (ATW) on well testing in 2010. He is also the author of SPE “well testing best practice” and pioneered numerical well testing through multi-discipline integration during his PhD study at Heriot-Watt in early 90s.

Following his 17 years’ successful career in Heriot-Watt, he was appointed as professor of petroleum engineering by London South Bank University in October, 2010, to take the leadership in research and teaching their UG and MSc petroleum programs.

Currently, he is the EAGE Award Committee member and the Board member of the SPE London Section as well as a technical editor for two journals on petroleum engineering.

Uncertainty in Reservoir Management

Instructor: Prof. Peter King (Imperial College London)

The course will give an introduction into many of the concepts behind uncertainty in reservoir modelling. It will start with a description of the origins of uncertainty with a mixture of heuristic treatments and more formal mathematical approaches. It will then develop the appropriate mathematical ideas and tools for estimating uncertainty in practical reservoir modelling.

Value of Information in the Earth Sciences

Instructor: Prof. Jo Eidsvik (Norwegian University of Science and Technology)

We constantly use information to make decisions about utilizing and managing natural resources. How can we quantitatively analyze and evaluate different information sources in the Earth sciences? What is the value of data and how much data is enough?
The course covers multidisciplinary concepts required for conducting value of information analysis in the Earth sciences.
Participants will gain an understanding for the integration of spatial statistical modeling, geomodeling and decision analysis for evaluating information gathering schemes. The value of information is computed before purchasing data. It is used to check if data is worth its price, and for comparing various experiments.

Handling Risk and Uncertainty in Mature Fields

Instructors: Dr Mark Bentley (AGR TRACS International) and Dr Richard Oxlade (AGR TRACS International)

The quantification of risk and uncertainty is often discussed in the context of exploration and appraisal, yet most of the upstream E&P business concerns decision-making in producing assets. This short course will therefore deal specifically with risk and uncertainty-handling in producing fields, the principal differences with E&A being the need to integrate production data in a practical way and the need to address the progressively changing questions that the production environment poses. Strategies for dealing with uncertainty are proposed under the generic headings of People, Tools and Team Approach, as effective uncertainty-handling involves finding practical team-based methodologies in addition to achieving a robust understanding of the underlying statistics and the available modelling tools.
