Summary

This course builds upon understanding the basic concepts and application of fault seal analysis using worked examples through a series of classroom based lectures and exercises. Participants will be introduced to the fundamental concepts of structural geology and fault seal analysis, before learning in detail how simplistic methods can be employed to gain a comprehensive understanding of fault sealing behaviour and risk.

Business Impact: This course provides participants with the skills and knowledge to characterise fault-related fluid flow during all stages of the E&P cycle in structurally-complex fields. Faults have the potential to act as significant seals in hydrocarbon reservoirs, withholding large fluid volumes over geological and production timescales. This course focuses on fundamental structural concepts that can be easily applied to most datasets, to generate an estimation of the seal capacity, and understand the risks associated with faulted reservoirs both in exploration and development settings.

Duration and Training Method

A classroom course comprising lectures, worked examples and training exercises. Lectures will focus on the theoretical concept of structural geology and fault seal analysis, and will include worked examples from exploration and development environments. Exercises will look at how methods can be applied to working datasets to evaluate sealing behaviour and address fault seal risk. 

Course Overview

Participants will learn to:

  1. Evaluate complex fault geometries using 2D and 3D approaches.
  2. Appraise how fault geometries impact hydrocarbon fluid flow.
  3. Characterise and identify faults that are likely to affect fluid flow.
  4. Evaluate the sealing potential of faults using simplistic models.
  5. Validate and quantify fault-seal associated risk.

Part one will focus on introducing structural geology theory to focus on how faults grow and develop in to complex structures that allow the trapping of hydrocarbons. Concepts of fault growth, segmentation, and linkage will be introduced and related to how different fault architectures impact flow.

Part two focuses on the components of faults that allow for the sealing / baffling of hydrocarbon flow. Fault rock processes (shale gouge ratio, shale smear factor) will be introduced to conceptualise how faults can form impermeable seals, and combined with seal capacity calculations to demonstrate how faults can become sealing through the calculation of hydrocarbon column heights.

Part three focuses on combining all theory and exercises in to worked examples of sealing evaluations and quantifying fault seal uncertainty in both exploration and development settings.

Background
Dan is a senior geologist at PDS Group, focusing as a project manager responsible for the development and commercialisation of various subsurface technologies associated with addressing structural and compartmentalisation uncertainty in faulted reservoirs. Dan is a consulting structural geologist with experience on a wide range of projects. From 2011 through to 2019, Dan worked as a senior consulting geologist and lead geomodeller at RPS, with particular focus on the study and characterisation of faulted and fractured reservoirs.

Prior to this, Dan worked on numerous projects as a consulting structural geologist at Rock Deformation Research Ltd., focusing on quantifying risk using fault seal analysis studies and later becoming the product champion for the PetrelTM Structural and Fault Analysis Module, delivering training and workshops on behalf of Schlumberger.

Dan graduated from the University of Leeds with a Masters in Structural Geology with Geophysics. His research focus was on reducing risk using fault seal analysis in siliciclastic reservoirs in the GOM, where his thesis received an award and was published and presented at a number of global conferences.
