Introduction

This interactive GLOMACS training course on Petrophysical Properties:  Core, Log and Test Data Integration will highlight the importance of data integration from a variety of sources to address complex reservoir evaluation and productivity challenges experienced throughout the full asset life cycle.

This GLOMACS training course will cover a variety of data sources, fundamentals of reservoir characterisation, and methodologies of integrating key information. This training course combines theory with practical exercises to give participants a working knowledge of how integrating available data at various scales can be used to evaluate reservoir quality, heterogeneity and improve the productive potential to maximize recovery of hydrocarbons.

This GLOMACS training course will feature:

  • Principles of rock and reservoir properties
  • The value of different data sources and purposes of data acquisition for reservoir analysis
  • Integration of core and log data to characterise flow units and reservoir properties
  • Provide hands on experience using field examples to evaluate complex reservoir conditions
  • Give advice regarding common pitfalls of data acquisition, interpretation and presentation of results

Objectives

By the end of this GLOMACS training course, participants will learn to:

  • Understand the benefits of data integration
  • Understand various sources of data and the purpose of data acquisition
  • Plan data acquisition programmes and oversee core handling and preservation techniques
  • Understand the role of routine and special core analysis in reservoir characterisation
  • Deduce reservoir properties from log interpretation and core analysis
  • Integrate reservoir and well data to provide an evaluation of the reservoir and characterize flow units
  • Avoid common pitfalls of data acquisition and analysis
  • Present and manage data appropriately

Training Methodology

This GLOMACS training course will present methodologies to integrate the various data types in conjunction with a number of exercises combined with field examples in a workshop format to enhance the learning and knowledge of the participants. 

Organisational Impact

Personnel will be able to:

  • Plan improved data acquisition programs
  • More effectively assess wider datasets for the benefit of a range of asset types
  • Work more effectively in a multi-disciplinary team and manage third party contractors
  • Appraise existing data sets and evaluations with the aim of reducing In-Place volume uncertainty

Personal Impact

  • Develop and build on existing knowledge of the collection and interpretation of core, log and test data
  • Learn the principles of data acquisition planning and be able to identify the best combination of tests and techniques for an optimal analysis programme
  • Gain an understanding of the pitfalls of the various data types and their potential implications
  • Raise self-assurance in evaluating previous studies
  • Provide confidence in managing third party relationships
