Analysis of Well Data for Clastic Reservoir Characterisation

Analysis of Well Data for Clastic Reservoir Characterisation - training course

The course examines various clastic depositional systems, reviews inputs required for static reservoir models and how these can be acquired from core, well data and outcrop. Emphasis is placed on careful analysis of the depositional system and its heterogeneity to highlight the key differences between depositional elements, their reservoir architecture, scales of correlatability and connectivity. The course helps address what subsurface data are fit for the modelling purpose, and how to select and use appropriate analogues.

This is a three-day classroom/core store course consisting practical core examination and analysis supported by lectures and outcrop montages.

Suitability - Who should attend?

The course is designed for geoscientists and engineers involved directly or indirectly in the development of clastic static reservoir models. Whilst an appreciation of reservoir modelling and clastic depositional systems is an advantage it is not a pre-requisite. Note that the course discusses modelling strategies and techniques and will not involve sitting in front of a workstation or the use of any particular modelling software.

Outcome / Qualification etc.

Participants will learn to:

  1. Integrate core, wireline and outcrop data to define a depositional model.
  2. Interpret and correlate facies and stratigraphic features away from data control.
  3. Evaluate depositional element correlation and its impact on connectivity.
  4. Establish subsurface correlatability and illustrate the relationship of clastic depositional elements to resultant reservoir architecture (be it sandstone, shale or coal).
  5. Determine the type of model that is required based upon the types of decisions that the model is expected to support.
  6. Select appropriate modelling parameters, scales and inputs to establish a model framework and capture scale-specific heterogeneity.
  7. Select appropriate analogues for your depositional system / model.
  8. Critique the various methods for the generation of static modelling input.

Training Course Content

Day 1

Basic principles:

  • Depositional models and correlation methods.
  • Difference between depositional elements, reservoir architecture and static elements
  • Why build reservoir models; modelling concepts and methods
  • Different types of models and the key parameters in model design
  • Review of subsurface data

Day 2

  • Assessment of depositional elements in core and well data
  • Consideration of scales of data and heterogeneity; thin section → core → well →outcrop
  • Reservoir architecture and correlation – case studies

Day 3

  • Core store and outcrop montage panels
  • Review of depositional elements in outcrop
  • Or continuation of Day 2 incorporating outcrop montage panels
  • Inputs for reservoir model in:
  • High data density areas (e.g. unconventional developments)
  • Low data density areas (e.g. exploration)
  • Examples of outputs of reservoir models
  • Away from the wells – what techniques to use and why
