SELECTION OF SAFETY EQUIPMENT BASED ON WELLHEAD MAXIMUM ANTICIPATED SURFACE PRESSURE CALCULATION

A study conducted at well TT-01/H (fictitious name for confidentiality purposes) in Vojvodina evaluates the efficiency and selection of pressure control safety equipment at the wellhead. Expected pressures at various depths and geological formations were analyzed, enabling precise equipment selection. Utilized equipment, including dual ram blowout preventers, exhibited high leak resistance and effectiveness in managing adverse scenarios such as fluid influx and gas channeling. Equipment testing procedures, conducted according to API standards, encompassed low-pressure and high-pressure tests, confirming operational readiness and equipment reliability. Simulations indicated that higher mud density reduces maximum expected pressures at the wellhead, contributing to system stability. Identified coupling issues were addressed with additional sealing measures, enhancing system integrity. Research findings affirm that suitable and regularly tested safety equipment is crucial for drilling safety and efficiency, with recommendations for maintenance improvement and further research aimed at optimizing safety strategies and monitoring technologies for well conditions.
