Human Factors Reliability Study of Oil and Gas Field Accidents

This study investigates human factors reliability in oil and gas field accidents, combining theoretical analysis with empirical data. It identifies that human factors contribute to 70–80% of accidents, underscoring the inadequacy of technical solutions alone and the need for systemic improvements. The research defines key concepts such as Human Error (HER) and Performance Shaping Factors (PSFs), categorizing errors into skill-based, rule-based, knowledge-based, omissions, and commissions. Using the HFACS-OGI framework, it reveals that 86% of accidents involve contractor personnel, with 90% attributed to suboptimal contractor working environments. High-risk operational phases include drilling and workover, while organizational influences like weak safety culture and insufficient training are critical. Strategies to enhance reliability integrate Human Factors Engineering (HFE), safety culture cultivation, and robust management—including proactive design, targeted training, and PSF management. The study emphasizes a systemic approach to address interlinked factors from individual behaviors to organizational-level latent conditions.
