<p>This paper introduces a conceptual framework—the ZEYBEK-1 Heuristic—developed specifically as a classroom teaching aid to help introductory geology students understand the geometric requirements of fault-bounded structural traps. The framework is intentionally simplified for pedagogical purposes: it translates basic petroleum system principles into explicit, coordinate-based geometric rules that define spatial relationships between source rock, reservoir rock, cap rock, and fault systems. Unlike operational exploration tools or research-grade software, ZEYBEK-1 is designed as a teaching scaffold—making implicit geological assumptions explicit so that students can examine and discuss the fundamental logic of trap geometry before encountering real-world complexity. A classroom illustration from the Gulf of Suez demonstrates the approach, with the explicit caveat that this example is for teaching only and does not constitute validation of predictive capability. The framework’s simplifying assumptions (vertical faults, horizontal bedding, 2D representation) are features for introductory instruction but become limitations in any other context. This paper outlines the framework’s intended scope as a pedagogical heuristic, its boundary conditions, and a research agenda for assessing its educational effectiveness. The framework is not a substitute for professional software or advanced analytical methods; it is a starting point for classroom discussion and should not be used for operational exploration decisions.</p>
