Fractured Reservoir Characterisation with Emphasis on Carbonates

Fractured reservoirs such as tight carbonates and basements set complex challenges to appraisal and development teams due to their high degree of heterogeneity and hard-to-predict reservoir quality. A multi-disciplinary approach that draws on sedimentology, diagenesis, structural geology, rock mechanics and reservoir engineering techniques has to be applied.

This course provides geologists and reservoir engineers with the essential knowledge needed in the real-world business context where management of risk and reduction of uncertainties is important. The objective is to present the key technical issues in geology, geomechanics and engineering and illuminate the range of tools and techniques available to tackle them (along with their limitations). A constant theme is to illustrate these issues with case histories from the industry.

The course is intended to be interactive in that delegates are encouraged to participate in discussions so that key points are openly scrutinised.

A constant theme of the course is to apply ‘first principles’ from geological science to the results generated by reservoir characterisation tools, techniques and modelling softwares. With due attention to these principles the technical and commercial risks associated with fractured reservoir hydrocarbon developments can be mitigated.

    Day 1

    • Issues, Challenges, Geology Basics
      • o Overview of Key Characteristics and Issues in Fractured Reservoirs
      • o Structural Geology and Rock Mechanics for Fractured Reservoir Characterisation

    Day 1 will give delegates much of the foundation knowledge critical to understanding the challenges associated with fractured reservoirs and addressing their solutions. We will make a start on the essential technical knowledge in geology and geomechanics.

    Day 2

    • Geology Basics, Data and Techniques
      • o Structural Geology and Rock Mechanics for Fractured Reservoir Characterisation
      • o Data Sources and Appraisal Techniques for Fractured Reservoir Characterisation

    Day 2 will complete the essential technical knowledge in geology and geomechanics and then address the range of data sources and appraisal techniques available, mainly at well-scale but also covering reservoir scale methods such as seismic attributes. This will be a critical look at their relative merits so that delegates acquire an appreciation of their usefulness.

    Day 3

    • Modelling, Case Histories, and Drilling
      • o Fractured Reservoir Modelling and Case Histories
      • o Geomechanics and Drilling Issues in Fractured Reservoirs
      • o Re-Cap and Wrap-Up Discussion Session

     

    Day 3 focuses on the reservoir scale methods associated with upscaling and construction of reservoir models for simulations, reserve assessments, and field development planning. We then review geomechanics applications and drilling-related issues such as wellbore stability in fractured formations.
