Introduction

Fault seal analysis is a critical discipline in petroleum geology and reservoir engineering, directly influencing hydrocarbon trapping, field development strategies, and risk reduction in exploration and production activities. Understanding whether faults act as barriers or conduits to fluid flow is essential for accurate reservoir characterization, volumetric estimation, and production planning.

This training program, designed and delivered by Global Horizon Training Center, provides a comprehensive and applied understanding of fault seal mechanisms, analytical techniques, and decision-making frameworks used in exploration and development projects. The program bridges geological theory with real-world applications, enabling participants to evaluate fault sealing behavior and integrate results into subsurface models and development plans.

Program Objectives

By the end of this program, participants will be able to:

• Understand the geological and geomechanical principles governing fault seal behavior

• Apply fault seal analysis techniques using geological, petrophysical, and pressure data

• Assess fault-related risks during exploration, appraisal, and development phases

• Integrate fault seal evaluation into reservoir modeling and field development planning

• Support decision-making related to well placement, compartmentalization, and production strategy
