Abstract

To appraise remaining behind casing opportunities in brown field after years of production, and depletion of main perforation intervals. Offshore environment is challenging and ensuring the presence of hydrocarbon requires significant investment, which is not always viable due to the economical additional reservoirs margin. A novel multidisciplinary workflow is developed to add assurance in apprising the remaining opportunities within the Idle wells prior to progress towards plug and abandonment. Limited data availability and economics allowed the development of a workflow to reduce uncertainty and ensure the presence of hydrocarbon when no cased hole saturation logging is justifiable. The workflow starts by relooking into the open hole logs to identify additional or marginal reservoirs. A complication index is assigned to each which refers to the easiness of the planned additional perf and the success ratio based on open hole data. A complete study to nearby wells production and the water oil contact movement is carried out based on the assigned complexity index. Opportunities were then ranked against the economics of additional perforation, cement bond logs were used to identify behind casing channeling especially when a gas or water contact is interpreted. The workflow which integrates the reservoir static and dynamic sand aligns petrophysics, dynamic model, history match and contact movement is developed to mitigate any behind casing opportunity consequent to no cased hole logging possibility, and to minimize the risk of not encountering hydrocarbon due to the long production. Any misleading allocation, potential risk (sand, wax, gravel pack, other completion accessories), predict future production based on location of new perf, plan for simulation or production enhancement job, remedial job, identify potential fault (unseen) at limited pressure data block, The workflow is proven to be successful to derisk the presence of hydrocarbon and to identify the most promising hydrocarbon bearing formations, with positive results as perforations are carried out where hydrocarbon are flew. This novel, comprehensive and integrated workflow generated a reliable tool to identify remaining potential trapped behind casing and possible risks of fluid type, current contact, impurities and well completion. The workflow is developed to generalizes the methodology to assess remained hydrocarbon within idle or high water cut wells, with risk reduced because each discipline contributed to the assessment with the potential risk associated with their discipline. Proper plan is together, capturing all possible risks and ensuring capturing the remained hydrocarbon.
新型集成后套管时机成熟工作流程
评估棕地生产多年后剩余的套管机会,以及主要射孔层的枯竭情况。海上环境具有挑战性,确保油气的存在需要大量投资,由于额外的储层边际经济,这并不总是可行的。开发了一种新的多学科工作流程,以确保在进行封井和弃井之前通知闲置井中的剩余机会。有限的数据可用性和经济性允许开发工作流程,以减少不确定性,并确保在没有套管井饱和测井的情况下存在油气。工作流程从重新查看裸眼测井曲线开始,以确定额外的或边缘的储层。每个井都有一个复杂指数,指的是根据裸眼数据计划的额外射孔的难易程度和成功率。根据给定的复杂性指数,对附近井的生产和水油接触面运动进行了全面的研究。然后根据额外射孔的经济性对射孔机会进行排序,水泥胶结测井用于识别套管后窜,特别是在解释气或水接触时。该工作流程集成了储层静态和动态砂岩排列、岩石物理、动态模型、历史匹配和接触面运动,以减少由于没有套管井测井的可能性而导致的套管落后的机会,并最大限度地降低由于长时间生产而没有遇到油气的风险。任何误导性配置、潜在风险(砂、蜡、砾石充填、其他完井附件)、根据新射孔位置预测未来产量、计划模拟或增产作业、补救工作、在有限压力数据块下识别潜在故障(未见)。该工作流程被证明是成功的,可以冒着油气存在的风险,识别最有希望的含油气地层。在油气运移的地方进行射孔,取得了良好的效果。这种新颖、全面、集成的工作流程产生了一种可靠的工具,可以识别套管后剩余的潜在被困物,以及流体类型、当前接触、杂质和完井的可能风险。开发该工作流程是为了推广评估闲置井或高含水井中剩余油气的方法,降低风险,因为每个学科都为评估提供了与其学科相关的潜在风险。适当的计划是结合在一起,捕捉所有可能的风险,并确保捕获剩余的碳氢化合物。
