ICE FT 08 | Fractured Carbonate Reservoirs Outcrops: Observing Faults Fractures and Karsts Permeability Networks in Different Carbonate Depositional Settings
Sponsored by the American Association of Petroleum Geologists (AAPG)
Thursday, 19 October – Sunday, 22 October 2017, 2:00 p.m.–3:00 p.m. | Bari, Italy
Who Should Attend
Geologists and reservoir engineers interested in carbonate and fractured reservoirs modeling.
Objectives
To gain an understanding of the complexity, the issues and the positive sides of carbonate fractured reservoirs.
Course Content
Fractured carbonate reservoirs are liable to display large variability in their characteristics which can affect their performance and economic viability. Primary facies distribution and properties, sequence stratigraphic framework, diagenesis and fracturing are amongst the main factors that exert important controls on reservoir properties.
In these reservoirs the interaction between matrix characteristics (facies, layering, poro-permeability, wettability) and fractures characteristics (timing, style, sizes, distribution, orientation) invariably control fluid flow by enhancing or imparting primary reservoir properties. As a result the understanding of fracture distribution and in particular the relationship between fractures and sedimentary facies is fundamental for an adequate description of fractured carbonate reservoirs.
Understanding these relationships is key to correctly model matrix storativity and fracture connectivity and identify potentially highly productive intervals. This field trip gives participants a chance to look at different carbonate depositional settings ranging from internal platform/lagoon to platform margin and to slope and basinal. In these different depositional settings different types of carbonate sediments were accumulated with different textural and petrophysical characteristics and different depositional geometries. In each setting it is possible to observe how fault and fracture developed and what are the main controlling factors at different scales.
The sequence that will be observed belongs to the Apulian Carbonates, and spans in age from Cretaceous to Pliocene.
By using the outcrops of the Apulian Carbonates and subsurface data from equivalent reservoirs of southern Italy the field trip will cover the following topics:
- understand the 3-D organisation of facies (depositional model and sequence stratigraphic framework) from large (regional) to meso (reservoir) scale;
- identify, describe and distribute reservoir characteristics (mainly porosity type and origin) of the carbonate facies ranging in age between Cretaceous to Pliocene;
- understand the hierarchy, distribution and organisation of the fault and fracture networks and their relationships with tectonic structures in different tectonic settings;
- verify and characterize the relationships between sedimentary facies and fracture distribution in different structural conditions;
- observe the characteristics of a multistage karst network and the 3-D distribution to understand impact on reservoir performances.
