Ananda Shankar Roy will speak about:

Integrated Facies Analysis for Turbidite Reservoir Characterization and Static Model Update:

a case Study from Well 14/26b-5, CNS

Abstract

This study demonstrates that borehole image log–based facies analysis, when integrated with seismically resolvable geomorphology, provides an effective means of characterizing turbidite fan complexes and constraining depositional architectural elements and geometry for reservoir modelling. The results significantly improve the understanding of reservoir connectivity and address the uncertainty in the static model definition for the Thunderball Field, offering refined inputs for future dynamic simulation and field development planning. An integrated structural and facies interpretation was carried out on Well 14/26b-5 in the Thunderball Field, Central North Sea (UKCS), using Formation Micro-Imager (FMI) logs, open-hole petrophysical data, and integrate 3D seismic attributes to constrain the depositional architecture used in the static reservoir model of the Burns Sandstone Member part of the Kimmeridge Clay Formation. The strong correlation between seismic attributes and image log–derived facies validate the integrated workflow in terms of geological control in distribution of the turbidite facies beyond the well bore.

 

About the speaker

Ananda Shankar Roy is an independent geoscientist with over 24 years of experience in reservoir characterization, borehole image interpretation, seismic–well integration and PSM. He has worked extensively on North Sea, West African, South Asia and Indian offshore basins, focusing on deepwater turbidite systems and complex clastic reservoirs. Ananda has held technical roles with companies including Cairn India, Schlumberger and Halliburton, contributing to exploration and development projects through integrated structural, stratigraphic, and facies analysis. His current work emphasizes applying borehole image logs and seismic attributes to refine depositional models and update static frameworks for improved field development planning.
