Production Optimisation System

12 November 2017, 0800–1700 hours

The basic objective of this course is to introduce the overview and concept of production optimisation, using nodal analysis as a tool in production optimisation and enhancement. The participants are exposed to the analysis of various elements that help in production system starting from reservoir to surface processing facilities and their effect on the performance of the total production system.

A total producing system as a group of components encompasses reservoir rock, completions, vertical flow strings, reassertions, horizontal, inclined flow lines, risers, gathering system networks, compressors, pump stations, metering system, and market system rate/pressure. An improper design of any one component, or a mismatch of components, adversely affects the performance of the entire system. Nodal analysis identifies bottlenecks and serves as a framework for the designing of efficient field-wide flow system including wells, artificial lift, gathering lines, and manifold. Production optimisation analysis is also used in planning new field development.

Practical Depth Conversion and Depth Imaging for the Interpreter

12 November 2017, 0800–1700 hours

The following depth conversion and velocity topics will be covered:

  • Overview of Depth Conversion
  • Sources of Velocity/Defining Velocity Types
  • Well and Seismic Data Integration
  • Vertical Time-to-Depth Conversion (Basic)
  • Applications and Pitfalls of Vertical Depth Conversion
  • Time and Depth Migration: Comparisons
  • Migration Algorithms: Theory and Practice
  • Tomographic Velocity Analysis
  • Well/Seismic Validation
  • Anisotropy
  • Well Calibration

Depth conversion of time interpretations is a basic skill set for interpreters. There is no single methodology that is optimal for all cases. Next, appropriate depth methods will be presented. Depth imaging should be considered an integral component of interpretation. If the results derived from depth imaging are intended to mitigate risk, the interpreter must actively guide the process.

Participants will gain an understanding of depth conversion methodologies and QCs for validity of methods used. Also, they will learn how to effectively design, guide, and quality control depth-imaging projects in a variety of geologic settings and be able to:

  • Assess the various sources and utility of velocities
  • Investigate the compatibility of well and seismic data using synthetics and other methods
  • Assess the differences between time and depth migration
  • Characterise the underlying theory between ray and wave-equation methods
  • Assess the differences between migration algorithms
  • Appraise the form of velocity updating (tomography) appropriate for the geology
  • Plan and review QCs for iterative velocity updates
  • Assess the method used for determining anisotropic parameters
  • Implement an optimal approach for calibrating well and seismic data
  • Who Should Attend?

    1. This course is aimed toward geoscientists involved in seismic interpretation and subsequent time-to-depth conversion, in addition to incorporating pre-stack depth migration into their seismic evaluations.

Improving Exploration Investment through Risk Management, Uncertainty Recognition and Decision Analysis


Oil and gas exploration and production is a high risk, high cost and high reward industry. Investment analysis is becoming more complex with a low price environment, more challenging environments and changing regulatory trends requiring non-standard innovative solutions. The depletion of the larger conventional onshore and shallow water reserves is driving the industry to deeper water as well as unconventional resources such as shale gas and coal bed methane or the development of fields previously considered non-commercial. Marginal fields are being reconsidered with the introduction of better resource definition methods such as 3D seismic or reduced development costs through the deployment of improved drilling methods such as multilaterals or horizontal completions.

As a consequence of the need to tackle new reservoirs with new appraisal and development techniques in more challenging operating environments the risks are often increased and there are many uncertainties which are difficult to quantify. The result is greater vulnerability of many projects to fluctuations in commodity price, resource recovery and cost.

Learning Level


Course Length

1 Day

  • Why Attend?

    1. The ability to recognise, quantify and express uncertainty, risk and vulnerability are key skills for oil and gas professionals and decision makers that will be developed from this course.

      Successful exploration, production and development relies on appropriate decision analysis in order to mitigate risks, cut costs, understand vulnerabilities and reduce time frames. In particular the application of risk and uncertainty techniques to the interpretation of geology, geochemistry and geophysics to evaluate exploration prospects and discovered resources is of significant importance.

      This seminar will focus on enabling participants to understand and apply the tools and methods of identifying, quantifying and managing risks and uncertainties involved with prospect evaluation, resource assessment and project execution through the exploration, development and production life cycle.

      Mastering these concepts and the learning of the methods of analysing and making risk based decisions is expected to result in improved evaluation and management of exploration projects. Those working on exploration, appraisal and development projects will find it relevant to attend this seminar.

  • Who Should Attend

    1. This seminar is intended for upstream professionals and management engaged in exploration prospect generation, prospect analysis, portfolio management, resource evaluation, project planning, project execution and project management.
