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.

油气井的封堵和弃井作业是油气威尔斯井生命周期的最后阶段。P&A作业的主要目标是密封油井并永久保持油井完整性，以防止环境灾难，例如含水层污染、浅层地层压力崩溃和流体泄漏到不同层。行业对P&A业务的运营、技术和监管方面的兴趣目前很高，并可能在未来几十年继续迅速增长。一般来说，P&A作业的重要步骤如下：（i）进入井的环形部分，（ii）清洁缺陷区域，以及（iii）将水泥塞屏障放置到目标区域。开发了一种基于喷射系统的新型压井、洗井和固井（PWC）技术，该技术可以显著降低P&A操作时间/成本。然而，P&A操作中的喷射系统是复杂的，这是由于存在许多参数的组合，例如几何参数、流体性质、操作条件等。（关于每个过程、每个井的条件和每个地区的具体政府规定），综合配套的存在似乎至关重要，以提高效率并减少操作时间/成本。在这种情况下，我们的工作旨在提供一个市场评估的设计和开发的工程软件包，基于流体力学方面。我们的创新软件提供优化的参数，从而减少P&A操作的时间和成本，并提高其成功率。
