Carbonate Systems and Reservoir Characterization and Unconventional Reservoirs

Carbonate depositional environments are inherently heterogeneous because of the superposition of sedimentary and diagenetic processes during successions of relative sea level changes. Projects in the modern environment use a combination of various types of remote sensing data and surface samples to capture the spatial trend metrics of sedimentary bodies. Surface samples from northwestern Great Bahama Bank are intended to refine the facies maps of this classic modern platform system.
Understanding flow, compartmentalization and mineralization in reservoirs depends on knowledge of the 3-D architecture of sedimentary structure and fracture network in the rock volume around the borehole. Several of our projects aim to increase our understanding of the lateral and vertical heterogeneity of facies and fractures. To achieve this goal, we have developed a new generation of 3-D Ground Penetrating Radar to retrieve the sub-meter scale variability of facies and flow units from Pleistocene grainstone shoals in the Miami Oolite and for fractures in several locations around the world. Seismic data from various regions are used to examine the evolution of carbonate systems in different tectonic settings and assess the influence of tectonic activity, sea level changes and sediment supply on the carbonate depositional system. Currently, we study seismic data from the Bahamas-Cuba foreland basin to decipher carbonate platform drowning as a result of increased subsidence during the formation of this foreland basin, and to delineate the evolution of the Gulf Stream from sediment drifts in the Bahamas region.
Reservoir heterogeneities and the large-scale distribution of reservoir quality dolomite have been the focus of projects in the Mississippian Madison Formation. Currently we are assessing the dolomitization processes in the Madison Formation and the correlation of the dynamics of the evolving foreland basin on the evolution of these ramp carbonates. In addition, we continue our research in relating mechanical stratigraphy to sequence stratigraphy. These projects will provide us with a methodology to predict to a certain degree the fractures from facies and stratigraphic information.
