Why is sequence stratigraphy so crucial for the exploration of natural resources?
Sequence stratigraphy is a method that helps to understand the evolution of sedimentation through time and space in sedimentary basins. Currently, regional studies that support the exploration of natural resources are based on the understanding of the sedimentary processes that form the deposits and the sedimentation breaks that limit them.
The exploration and production of natural resources formed or related to sedimentary processes depend on the construction of chronostratigraphic frameworks that allow paleogeographic reconstructions that in turn increase our understanding of the temporal and spatial distribution of deposits of economic interest such as source rocks, seals and reservoirs of oil and other natural resource deposits.
Objectives
Upon completion of this course, attendees are expected to:
- Learn the concepts and methodology of sequence stratigraphy;
- Propose chronostratigraphic frameworks applicable to the exploration and production of hydrocarbons and other natural resources, the storage of C and H, and the injection of contaminants;
- Use high-resolution sequence stratigraphy for reservoir zonation and characterization;
- Understand the impact of this approach on fluid injection and production performance.
Content
World-class outcrops of Mesoproterozoic, very low-grade metasedimentary rocks are found in Chapada Diamantina, one of the most beautiful Brazilian National Park. Strata are superbly exposed/preserved, and the rocks still exhibit primary structures. The studied interval represents continental to shallow marine sedimentation in an intracratonic sag basin.
Fieldwork is supported by facies analysis, GR logs, photo-mosaics, GPR lines and 3D virtual outcrop models. All data collected by attendees are used in-class through stratigraphic correlation exercises and integrated into 3D digital models.
