Rock Physics for Quantitative Reservoir Characterization in Exploration & Production

Introduction

Rock physics forms the critical foundation of Quantitative Interpretation (QI) workflows. enabling the accurate seismic reservoir characterization of for confident exploration and production (E&P). Most subsurface interpretation errors originate from poor data Quality Assurance and Consistency (QAC), inconsistent seismic petrophysics and rock physics model calibration, inadequate seismic conditioning, or inappropriate selection and application of rock-property estimation techniques such as seismic inversion or machine-learning (ML) algorithms.

This course provides a unified value-proposition approach that fills a critical skills gap by teaching participants how to integrate well logs, apply rock physics diagnostics, achieve consistent seismic petrophysical and rock physics modeling, and confidently perform seismic amplitude inversion or machine-learning–based property estimation to significantly enhance subsurface reservoir prediction.

Growing reliance on QI, inversion, and ML makes rock physics essential for reducing uncertainty, improving rock property and lithofacies estimation, and enabling confident exploration, appraisal, and development decisions.

Learner Outcomes

  • Perform well-log Quality Assurance and Consistency (QAC) and seismic data conditioning (SDC) to ensure reliable inputs for QI & reservoir characterization workflows
  • Produce consistent seismic petrophysics and calibrate site-specific rock physics models for clastic, unconventional, and fractured reservoirs Petro-elastic properties relationships
  • Generate and analyze synthetic seismograms to calibrate seismic data with well properties and improve seismic-to-well ties for more reliable reservoir characterization
  • Lithofacies estimation using seismic petrophysics, rock physics analysis, fluid-substitution modeling, and AVO/AVAz forward modeling and interpretation
  • Apply deterministic, probabilistic, and ML-assisted seismic inversion techniques to derive robust subsurface reservoir property predictions for quantitative reservoir characterization

Dr. Muhammad Zahid Afzal Durrani holds a PhD (2015) and MS (2011) in Geosciences from the University of Tulsa, along with a Master’s in Energy Business (2018) from the Collins College of Business. He previously completed an M.Phil. (2006) and M.Sc. (2003) in Geophysics, a PGD in Computer Sciences (2003) from Quaid-I-Azam University, and a bachelor’s degree in mathematics and physics (2000) from the Islamia University of Bahawalpur (Pakistan). He is currently advancing his expertise through a Post-Graduate Certificate in Carbon Capture, Utilization, and Storage (CCUS) at the Colorado School of Mines, focusing on climate change, sustainability, the political economy of the energy transition, and geological CCUS to support low-carbon innovation.

 

Dr. Durrani began his career in 2004 with Oil & Gas Exploration Company (OGCL) and Orient Petroleum (formerly Oxy Petroleum) in Pakistan, later collaborating with Newfield Exploration in Tulsa Oklahoma during his Fulbright scholarship and Bellwether fellowship funded MS leading PhD research In Tulsa University (USA) on the Unconventional resources (Granite Wash play) Anadarko Basin (USA). With more than two decades of industry experience, he has developed deep expertise in geoscience, rock physics modeling, quantitative interpretation, reservoir characterization, and CCUS-related reservoir studies. He has led complex exploration and appraisal projects across Pakistan, Iraq, and Abu Dhabi, and has extensive expertise in quantitative interpretation, rock physics, AVO/AVAz analysis, seismic inversion, and CCUS-related reservoir studies.

 

For the past decade, Dr. Durrani has built extensive expertise in quantitative reservoir characterization, international and new ventures, overseas exploration, and business development. In parallel, he holds over extensive professional and university teaching (as visiting faculty) and interdisciplinary research experience, bridging geoscience and engineering with a focus on sustainable hydrocarbon exploration, the energy transition, and industry–academia collaboration. He is at the forefront of perceptive Quantitative Interpretation (QI) and reservoir characterization leveraging advanced rock physics modeling, seismic petrophysics, and inversion workflows to improve reservoir prediction in unconventional (tight gas), fractured carbonate systems, and CCUS-related reservoir studies. He is equally committed to inclusive teaching, mentorship, and advancing interdisciplinary education in geoscience, energy management, and carbon capture, utilization, and storage (CCUS), including energy systems under environmental constraints.

 

Beyond his technical expertise, Dr. Durrani is a Certified Manager (ICPM – James Madison University, USA), a Certified Change Management Professional (CCMP) with Association of Change Management Professional (ACMP), a Prosci® Certified Change Practitioner, a crisis-management practitioner (Stanford Graduate School of Business), and is certified in

Measurement & Evaluation of Learning (GP Strategies). He also holds a Lean Six Sigma Black Belt (USA). He has a strong focus on business process improvement and advocates delivering quantitative solutions through the unified application of change-management and project-management principles. His approach emphasizes a unified value proposition (UVP) that strengthens the people side of transformation driving adoption, engagement, and proficiency across technical and organizational workflows.
