Abstract :A significant portion of energy resources has been discovered in offshore sectors, leading to a steadily increase in the volume of activities and operations. Once a well is drilled and fluid extraction begins, all the reservoir parameters, start to change. well test operation is one of the most crucial tools for engineers to comprehend the behavior and parameters of hydrocarbon reservoirs. In this study, the hazards associated with the well test operations has been identified by using HAZID technique. A total of 189 risks were identified in the initial risk assessment, with 35 categorized as low risk, 88 as medium risk, and 66 as high risk. Following the implementation of protection layers in the secondary risk assessment, the number of low risks incidents increased, while medium and high-risk incidents saw a significant reduction. Most of the identified risks are associated with loading operations and sea transportation from the port to the drilling rig. Since loading and unloading operations are critical and frequently occurring tasks in well testing, they contribute significantly to the overall risk profile.
