The plug and abandonment (P&A) operation is the final stage in the life cycle of oil and gas wells. The main goals of the P&A operation are to seal the well and permanently maintain the well integrity, to prevent environmental disasters, such as water-bearing zones contamination, shallow formations pressure breakdown, and fluids leakages to different layers. Industrial interests in operational, technological and regulatory aspects of P&A operation are currently high and likely to continue to grow rapidly in the coming decades. In general, the vital steps of the P&A operation are as follows: (i) accessing the annulus section of the well, (ii) cleaning the defected area, and (iii) placing the cement plug barriers into the target area. A novel perforate, wash and cement (PWC) technology based on jetting systems has been developed, which can significantly reduce the P&A operation time/costs. However, the jetting system in the P&A operation is complex due to presence of a combination of numerous parameters, such as geometrical parameters, fluids properties, operational conditions, etc. Therefore, to find the optimized parameters (regarding each process, each well condition, and specific governmental regulations in each region), the presence of an integrated package seems crucial, to enhance the efficiency and reduce the operation time/costs. In this context, our work aims to provide a market assessment for designing and developing an engineering software package, based on the fluid mechanics aspects. Our innovative software provides the optimized parameters, leading to reducing the time and costs of P&A operations and enhancing their success rate.
