Summary
Business Impact: Success depends on getting the basics right first time, and this course is designed to provide the frameworks for practitioners in the industry to develop new, and critically evaluate existing, geological models for carbonate reservoirs, based on the latest ideas and techniques. This enables meaningful assessments of risk and uncertainty to be made as well as the best decision making as regards well planning and reservoir modelling, all with clear business implications.
The course provides a thorough grounding in the concepts, terminology and models used to interpret, assess and predict carbonate reservoirs, assuming little prior knowledge. It will take the student from the seismic scale through to reservoir issues relating to dynamic simulations. Carbonate rocks are complex, but there are basic principles taught in the course that provide a framework for improving exploration success, and reducing the risk of inappropriate strategies being devised during appraisal and development of the reservoir.
Duration and Training Method
A virtual classroom course divided into 10 three to three and a half hour webinar sessions (equivalent to a five-day classroom course), comprising lectures, discussion, case studies, and practical exercises to be completed by participants during and between sessions.
Participants will learn to:
- Distinguish the principal carbonate sediment components, textures and systems of carbonate classification.
- Examine the primary controls on carbonate deposition temporally and spatially. Compare and contrast with siliciclastic deposition.
- Differentiate the main types of carbonate platform, their variability, scale and distribution of likely reservoir units.
- Demonstrate sequence stratigraphic aspects of carbonate build-ups, their differing response to sea level change compared to clastic sediments and discuss their seismic characters.
- Categorise the principal types of reservoir facies (platform interior, carbonate sands, reefs, slope systems and chalks), their recognition, architecture, sequence stratigraphy and porosity types.
- Differentiate the development of primary and secondary porosity through the combination of sedimentological, chemical and diagenetic processes.
- Compare and contrast carbonate pore systems and their reservoir characteristics with those developed in clastic sediments.
- Compare how the variety of diagenetic environments affect primary porosity in carbonate rocks and understand the implications for reservoir quality.
- Distinguish the principal modes of formation of dolomites and compare their reservoir properties with other carbonates.
Carbonate rocks contain over 40% of the world’s hydrocarbon reserves. Most earth science specialists have only had a rudimentary introduction to the topic at first degree level and there seems to be a mystique in the oil industry that carbonates are “too complicated”. The aim of this course is to provide an up-to-date introduction to practical carbonate sedimentology. Carbonate rocks are complex and there are many gaps in our understanding, but there are basic principles which provide a framework in which the complexity may be made understandable.
The course will commence with an examination of the principles of carbonate deposition and the factors that control the formation of carbonate systems. The main structure of the course falls into three parts with all aspects being firmly set in a sequence stratigraphic framework:
Part 1 outlines the seismic scale of carbonate systems. This will include a discussion of the types of carbonate platform, modern and ancient analogues, platform architecture, seismic recognition, play types and exercises.
Part 2 will summarise the reservoir scale of carbonates. The subjects covered will include all the key depositional systems including platform interiors, shoal belts, reefs, slopes and chalks. Criteria for recognition, key reservoir properties and common play associations will be distilled for each facies type. There will also be a discussions of key reservoir types for “reefs” such as rudists, Miocene buildups, buildups of late Paleozoic age. Reservoir case studies and exercises will be integrated into the webinar sessions. This section ends by studying sequence stratigraphic aspects and also drowned platforms.
Part 3 focuses on the origins of porosity, diagenetic environments, reservoir aspects, layering issues and techniques used to examine carbonate reservoirs. Two reservoir types are studied in detail – dolomite reservoirs, and palaeokarsts.

Who should attend
The course is structured to appeal to all geoscientists who wish to broaden and deepen their knowledge of carbonate reservoirs. The course will provide an effective working knowledge of these systems for graduate and inexperienced staff, while providing further insights to more experienced participants who require a more detailed application to subsurface projects.
Prerequisites and linking courses
There are no prerequisites for this class, although an understanding of the basics of sedimentology is an advantage.For those who wish to further expand their understanding of carbonate systems, there are a number of field classes available; N059 (Applied Carbonate Geology: Carbonate Facies and Reservoirs, Balearic Islands, Spain) examines Miocene ramps, reefs and associated facies. N494 (Controls on Carbonate Depositional Systems and Reservoir Characterisation (Oligo-Miocene - Apulia, Italy)) visits excellent outcrops of Upper Creataceous, Eocene, Oligocene and Miocene carbonates with varying dominant carbonate factories and platform morphologies. N091 (Carbonate Reservoir Architecture and Applied Carbonate Sequence Stratigraphy, New Mexico and West Texas) visits the Palaeozoic carbonate successions in the region and considers both exploration and production perspectives.

He has worked extensively on carbonate reservoirs in North Africa, offshore India, Kazakhstan and offshore Brazil, as well as in the Paris Basin, Abu Dhabi and West Africa. He has conducted field work widely in UK, Spain, Portugal, Oman and USA.
Paul has written over 140 research papers, and co-authored or edited several books including the main text book in carbonate sedimentology. He has supervised over 20 PhD students, most of whom work in the oil and gas industry. He has served on the editorial boards of several international journals.
He is now director of PW Carbonate Geoscience Ltd, specializing in consulting, training and mentoring in applied carbonate sedimentology. He is an honorary fellow at the National Museum of Wales, Cardiff.
Paul is the 2016 recipient of the Pettijohn medal for outstanding contributions to sedimentology and stratigraphy, awarded by SEPM (Society for Sedimentary Geology), and also recipient of the 2015 AAPG Grover E Murray Distinguished Educator Award.
