Simplifying Processes in the Offshore Decommissioning sector: Reducing P&A costs by 30% and emissions by 50%

该项目的目的是将即将到来的英国水域纳税人和平台运营商的退役账单降至最低。我们的主要关注点是由总并购成本驱动的最高成本份额。通过实施创新的技术解决方案，而不是部署高估的不良钻井或修井单元，也是减少总体二氧化碳排放的绝佳机会。我们已经为P&A确定了一种技术解决方案，该解决方案最终专注于运营商的需求，根据油井和平台的要求部署合适的工具。这种模块化的多作业系统能够在基本设置中进行组装，以满足低井类别的要求，同时如果存在较高的井类别，则可以选择进行升级。最大的不同之处之一是它对现有修井解决方案的巨大操作范围，因为它可以服务于P&A活动的所有阶段，并具有持续从油井中恢复旧完井的额外优势，而不会中断任何连接。该系统作为修井单元轻便紧凑，同时具有钻机的操作灵活性，该钻机针对最重要的P&A基准进行了优化，如提升速度或井下工具的处理。可行性研究侧重于创新的颠覆性技术解决方案的商业、技术和运营可行性。主要范围是开发3D软件中的基本设计，以支持其技术可行性。之后，3D插图将被转换为动画，以证明其操作能力，特别是处理P&A活动中从有线作业到完工恢复的所有必要事件。这种可操作性被转换为P&A工作的最关键基准，并通过P&A执行模拟工具在密集的商业分析中与现有系统进行比较。这一工具证明了运营能力、不同设置下的比较成本和排放节省，并考虑到了P&A的所有方面。其范围是达到建造将在试点项目中部署的演示器的技术准备水平。

The aim of the project is to minimise the upcoming decommissioning bill for the tax payer and platform operators in Uk waters. Our main focus is on the highest cost share driven by the total integrated P&A costs. There is also a great opportunity in reducing the overall CO2 emissions by implementing an innovative technical solution instead of deploying overrated distressed drilling or workover units.We have identified a technical solution for P&A which finally focuses on the operator demand to deploy the right tool depending on the well and platform requirements. This modular multi-operational system is capable to be assembled in a basic setup to meet low well category requirements while it has the option to be upgraded if higher well categories are present. One of the biggest differentiator is its large operational envelope to existing workover solutions as it can serve all P&A campaign phases with the additional advantage of continuously recovering the old completion from the well without any breaks for connections. The system is light & compact as a workover unit while it has the operational flexibility of a drilling rig optimised to the most important P&A benchmarks such as the hoisting speed or handling of downhole tools.The feasibility study focuses on the commercial, technical and operational viability of the innovative disruptive technical solution. Main scope is the development of a basic design in a 3D software to support its technical feasibility. Afterwards, the 3D illustration will be converted to an animation for proving its operational capabilities, especially dealing with all necessary events in a P&A campaign from wireline jobs to completion recovery. This operability is transformed to the most critical benchmarks for a P&A job and compared to existing systems in an intensive commercial analysis by a P&A execution simulation tool. This tool proves operational capabilities, the comparative costs and emission savings in various setups, taking into account all aspects of P&A . The scope is to achieve a technical readiness level for the build of a demonstrator that will be deployed in a pilot project.
