Abstract

While optimizing hydrocarbon production, combining well intervention solutions can enable significant benefits due to reductions in risk exposure: fewer rig-ups and downs, less in-the-hole operating time and the carbon production and costs associated with rig time, especially when working from sub-sea intervention vessels. Operators in general, prefer to achieve multiple intervention objectives in a single descent in the well, if the operations complexity does not increase the risk exposure to an unacceptable level. Often, the risk of a mis-run, causing a second run, meets the cost vs value criteria for acceptable risk, when the large operating time savings of a successful combined run is considered. In collaboration with a mechanical e-line provider, North Sea operators developed three reliable combination solutions which increased their operational efficiency. Combining these most run services under more standard, common scope of work procedures, saved the operator time in planning, execution, risk exposure and money, while enabling them to produce hydrocarbons in the saved time. This paper will present the technology involved with these combined services, use a typical example of each and the cost savings achieved.
结合油井干预方案优化生产、降低风险的案例
在优化油气产量的同时,结合修井解决方案可以降低风险,从而带来显著的效益:更少的起起落落、更少的井下作业时间、更少的碳产量和与钻机时间相关的成本,尤其是在海底修井船上作业时。通常情况下,如果作业的复杂性不会使风险增加到不可接受的程度,作业者更倾向于在一次下井中实现多个修井目标。通常,当考虑到一次成功的联合作业所节省的大量作业时间时,误入导致第二次作业的风险符合可接受风险的成本与价值标准。北海作业者与机械电缆供应商合作,开发了三种可靠的组合解决方案,提高了作业效率。将这些服务结合在更标准、更通用的工作程序范围内,节省了作业者在规划、执行、风险暴露和资金方面的时间,同时使他们能够在节省的时间内生产碳氢化合物。本文将介绍与这些组合服务相关的技术,并使用每个服务的典型示例以及所实现的成本节约。
