FRACTURED CARBONATES FIELD COURSE

Fracture analysis, facies and architecture of carbonate depositional systems

JUNE 10-14, 20192020 version

Appraisal and development of fractured carbonate reservoirs remains a signi�cant challenge because of the generally high degree of heterogeneity in the intensity, distribution and connectivity of the open fracture system. This course uses analogue outcrops and classroom sessions to equip the oil industry geoscientist and reservoir engineer with the essential knowledge from structural geology, fracture characterisation and rock mechanics to work with fractured carbonates.

Leaders: Jon Gutmanis and Lluís ArdèvolLocation: south-central Pyrenees, the course begins and ends in BarcelonaCost: EUR 2,850Dates: June 10-14, 2019Limit: 12 participantsLevel: basic / skillDelivery: �eld trip + 1h daily classroomPhysical demand: average hike (maximum 1h walk per day) with some hills

Course outlineOutcrops

• Triassic and Jurassic dolomites (Adons, Camarasa)• Upper Cretaceous inner shelf to shelf-margin limestones (Tremp basin)• Eocene ramp carbonates (Alinyà anticline)

Facies

• Shallowing upward cyclicity in carbonates• Coral and rudist reefs, reef zonation• Mixed shelf deposits• Shelf zonation

Fractures

• Overview of fractured reservoirs (classroom)• Structural geology and geomechanics for fractured reservoir characterisation (classroom)• Introduction to carbonate fracture models with case histories (classroom)• Carbonate fracture types, properties and scales: from pressure solution fractures to stratabound joints to fracture corridors to large faults and their damage zones• Relationships between fractures, facies and mechanical stratigraphy• Characterising and predicting fractures in the sub-seismic volume• The coupled relationship between in situ stress, mechanical anisotropy and fracture distribution• Characterising fault damage zones• Fracture mapping exercises

Standard daily programObjective: to take the group through the fractured carbonate reservoir characterisation work�ow. We will integrate classroom sessions with discussions at specific outcrops to present the essentials of rock mechanics, fracture characterisation and static model development.
