Summary

This reservoir characterisation and modelling course focuses on capturing the geological knowledge necessary to build realistic models of coal-bearing fluvial and deltaic sediment body architecture. Outcrops, cores and well logs are studied to characterise both small and large-scale patterns of sedimentary architecture within a sequence stratigraphic framework in these Carboniferous coalbearing fluvio-deltaic sediments. 

Duration and Training Method

A five-day field and classroom-based reservoir geology and modelling course blending outcrop instruction with corresponding instruction in building 3D Petrel models of the same outcrops. Generally, the mornings are spent in the field with afternoon classroombase modelling sessions.

Participants will learn to:

  1. Evaluate and characterise the individual facies components and facies associations of coal-bearing fluvio-deltaic depositional environments using core, log and outcrop data.
  2. Construct a sequence stratigraphic-based framework for the reservoir modelling of coal-bearing fluvio-deltaic depositional environments.
  3. Construct a realistic conceptual model against which the final 3D reservoir models can be checked.
  4. Integrate core, log and any other available data to build a reservoir model which distributes reservoir properties realistically in 3D and establishes flow and non-flow units within it.
  5. Perform deterministic modelling of coal-bearing fluvio-deltaic sediments using Petrel and compare results from different Petrel modelling techniques in order to formulate the best modelling strategy.

The course follows the typical workfl ow of a subsurface 3D modelling project and is aimed at fluvio-deltaic reservoir characterisation and making realistic predictive models of sedimentary geometries and architecture by incorporating detailed knowledge of sedimentology and sequence stratigraphic concepts.

Although the class is based around coal-bearing fl uvial and deltaic outcrop examples, many of the techniques can be easily adapted to other depositional environments.

The primary topics covered in the course are:

1. Diagnostic outcrop, core and log interpretation of coal-bearing fluviodeltaic environments and facies
2. Building a sequence stratigraphic framework in coal-bearing sediments for reservoir modelling
3. Coal and coal-bearing sediment correlation techniques from well data
4. Deterministic modelling techniques for coal-bearing sediments using Petrel
5. Using Petrel hierarchy, zone logs and layering
6. Comparison of modelling results from different Petrel techniques
7. Creating and using isochores to control shapes of sediment bodies
8. Analysis of static connectivity of different facies modelling techniques
