N335 Modelling Clastic Reservoirs (Pyrenees, Spain)
N335 Modelling Clastic Reservoirs (Pyrenees, Spain)
This course provides an introduction to designing and building reservoir models of clastic depositional systems through to dynamic flow simulation. The course stresses the role of the conceptual facies modelling as a tool for distributing petrophysical properties within the model and reviews a range of clastic depositional systems in renowned outcrops of the Spanish Pyrenees.
A six-day field course in the Spanish Pyrenees with classroom lectures and exercises. The proportion of field time to classroom time is approximately 60:40. Field examination of depositional systems at both seismic and, more commonly, sub-seismic, sandstone body scale including team exercises, backed up by model results and supporting presentations.
Participants will learn to:
The technical content of the course can be considered in a matrix. One axis of this matrix is the specific depositional environment (fluvial, shallow marine, deep marine) the other is the various stages of the reservoir modelling workflow. This work flow can be summarised as follows:
Many aspects of stages 2 to 5 will differ, depending upon the specifics of the depositional environment. We will start by reviewing and understanding that work flow and the implications it has on model building. Then we will visit outcrop examples of all of the key types of depositional system and review the key specifics of zoning, grid building and grid population at each building up a better understanding of the model building process and also the role of facies as carriers for petrophysical properties.
Throughout the course we will conceive an overall sedimentological model for the outcrops and take a reservoir engineering perspective on the observed heterogeneity - does any of it matter? Outcrop-based permeability data will be used to support the observations on heterogeneity and to discuss how small scale heterogeneity can be reasonably scaled in to a simulation model. Outcrop-based models will also help define, from an engineering perspective, the concept of effective net.
This course is multi-disciplinary. It is designed for geoscientists, petrophysicists and reservoir engineers involved in developing descriptions and models of reservoirs.
Participants will gain the greatest benefit if they have a basic understanding of reservoir geology and reservoir engineering. Individuals inexperienced in reservoir science should consider course N008 (An Introduction to Reservoir Appraisal and Development) as a precursor. This course is also a natural extension of N155 (Introduction to Clastic Depositional Systems: a Petroleum Perspective) and N156 (Clastic Depositional Systems in a Basinal Framework: Exploration and Reservoir Implications (Pyrenees, Spain)).
Participants may wish to attend courses (at Skilled Apllication Level) exploring in greater detail outcrops visited on this course. These include the fluvial modelling course N108 (Exploration and Geological Model Development in Fluvial Reservoirs) and the deepwater course N028 (Sand-rich Turbidite Systems and Megaturbidites: From Slope to Basin Plain. Facies, Stacking Patterns and Controlling Factors).
N058 (Reservoir Characterisation and Geostatistical Modeling in Field Development) is a classroom and computer based linking course, whilst N012 is similar in content but based in Utah, USA. N106 (Advanced Reservoir Modelling) follows on from this course in the Reservoir Development curriculum.
The physical demands for this class are LOW according to the Nautilus field course grading system. Access to the outcrops is relatively easy. The longest walk on the field course is approximately 3 km (1.8 miles) along a hillside track. Other short walks of up to 1 km (0.6 miles) take in roadside sections, quarries and scrubby hill land. Participants should be aware that some localities are at an altitude of around 1000 m (3000 ft) and field temperatures may exceed 25 degrees celsius.

John Howell read for a PhD in reservoir sedimentology at the University of Birmingham (1992). He proceeded to the University of Liverpool where he spent 10 years working as a researcher and lecturer. During that time he participated in numerous oil industry funded projects, collaborating with virtually all the major oil companies, primarily in the fields of sedimentology, sequence stratigraphy and latterly reservoir modelling. In 2002 he took a professorship at the University of Bergen to further his applied research interests in analogue reservoir modelling. In 2005 he was one of the founders of Rocksource, a Norwegian Independent E&P Company. He worked there in the senior management until end 2011 initially as the Production Manager and latterly the CTO. IN 2012 he left Norway and returned to academia. He has worked in a diverse range of basins on six continents, published over 100 scientific papers and edited 3 books. He was an AAPG distinguished lecturer in 2009.

Ed is a consultant reservoir engineer with 14 years experience, providing field studies, 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, integrated circuits and software. He then joined the Shell International E&P as a reservoir engineer with assignments in Netherlands, Nigeria and Brunei. He worked first with the simulator development group, then on well testing interpretation, the modelling support helpdesk, and delivering training. Then he worked with the Nigeria field studies team, at that time preparing the major upstream gas for LNG developments. In Brunei he was reservoir engineer for the Fairley asset area, mixed light oil rims and non associated gas with some 60 wells in 300 reservoirs, supporting well delivery, well operations, reservoir management, reservoir studies, reserves review, exploration support and business planning.
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.
