Using analogue outcrops in the Luberon and Cassis area of Southern France, this course develops workflows for characterisation and modelling in carbonate reservoirs, covering in particular the issues of conceptual reservoir characterisation, the handling of scale, and the representation of fracture detail in cellular models. The outcrop section is a direct analogue for Shuaiba/Kharaib Middle East reservoirs, including high and low energy areas of rudist platforms, inner and outer shelves, and chalks. The modelling principles are transferable to other carbonate environments.
Business Impact: The bulk of the world's oil and gas resources are in carbonate reservoirs, so forecasting productivity in carbonates is fundamental to our business; This course makes the link between reservoir characterisation and how fluids flow in these heterogeneous reservoirs, unravels some of the reasons why our forecasts are often incorrect, and offers guidance on however to improve those forecasts.
Feedback
"I really enjoyed this course and I'll recommend it to my colleagues for the following reasons: right balance between outcrop observations and 'modelling' exercises; great manual/material; new (and clearer) approach to modelling philosophy."

Duration and Training Method
A five-day field-based course based in Provence, Southern France. The event will be conducted wholly in the field. Outcrop-based reservoir models and forward-modelled seismic will be used to support discussion. The focus will be on experiential learning with mixed-discipline group-based tasks. Short talks will be given at the outcrop and simple calculations demonstrated using rules-of-thumb to assist analysis.This course will make use of Digital Outcrop Imagery (DOI).
Course Overview
Learning Outcomes
Participants will learn to:
- Characterise a carbonate reservoir in terms of essential reservoir elements and describe the architectural arrangement of those elements.
- Evaluate reservoir property distributions for those elements in a form suitable for input to static/dynamic reservoir modelling.
- Judge the scale at which a static/dynamic modelling exercise should be conducted, including any need for multi-scale modelling.
- Prepare rules of thumb for effective property modelling in carbonates at a range of scales.
- Assess fracture systems in carbonates and explain the options for modelling them (explicit DFN vs. implicit effective properties).
- Apply the concept of representative elementary volumes (REV) to fractured and unfractured carbonates.
- Analyse the seismic expression of large scale outcrops based on underlying cellular model description.
- Evaluate the issues governing well placement in carbonates under a range of conditions.
- Propose an optimal development plan for a carbonate reservoir under a range of contrasting fluid fills.
Course Content
Carbonate reservoirs are often poorly-modelled and the distinction between workflows for carbonates and clastics missed. The lack of clear k/phi relationships in carbonates distinguishes them from their clastic counterparts, and fractures in particular can be difficult to model without convoluted workflows. The course tackles these issues and gives practical advice on how to model these reservoirs.
Reservoir modelling schemes are applied to contrasting analogue outcrops, covering environments ranging from inner to outer platforms through shelf to proximal basin, including a spectactular karstified fracture system. The outcrops selected are age-equivalent analogues for Middle Eastern Shuaiba/Kharaib carbonates on the opposing side of Tethys. Specialist interpretative input to the course is provided by Jean Pierre Masse from the University of Marseilles, an authority in his field.
Topics covered include:
- Carbonate reservoir characterisation
- Fracture characterisation
- Model scale and upscaling
- Representative elementary volumes in carbonates
- Seismic forward modelling in carbonates
- Well placement
- Simulation and forecasting in carbonates

Instructors
Mark Bentley
Background
Mark has over 30 years industry experience, initially as a production geologist with Shell, working in the UK, Oman and the Netherlands and subsequently training and consulting with TRACS. He has spent most of his career working in integrated study teams on a wide variety of reservoir assets. His specialist fields of expertise are 3D reservoir modeling and scenario-based approaches to handling subsurface uncertainty and risk. He publishes widely on the topic and co-authored the reference text 'Reservoir Model Design' with Phil Ringrose.
In addition to his role as Training Director at TRACS, he is also an Associate Professor in the Institute of GeoEnergy Engineering at Heriot-Watt University, holding a Chair in the field of Mature Field Management.

Ed Stephens
Background
Edmund Stephens is a reservoir engineer who has been in the petroleum industry since 1997, with experience in reservoir studies, field development planning, asset valuation and reserves reviews to a global customer base with a wide variety of reservoir and operational settings.
After research studies in physics at Oxford and Seattle, he worked for some years in electronics and software. He then joined the Shell International E&P with the simulator development group, well testing and delivering training. He worked as reservoir engineer on assets in Netherlands, Nigeria and Brunei, including a range of geological settings and fluid types supporting well delivery, well operations, reservoir management, reservoir studies, reserves review, exploration support and business planning. As principle reservoir engineering consultant with TRACS, he is involved in many projects across the globe including giant clastic and fractured carbonate field and development planning reviews. In the last few years he has worked on unconventional assets including tight systems and fractured basements. He is also experienced with energy transition projects including carbon sequestration (CCUS) and geothermal energy recovery.
Ed is expert in reservoir modelling and simulation, field development planning, reserves preparation and categorisation, asset valuation, business planning support and exploration support. He speaks English, French and some Dutch.
