摘要：
Systems and methods facilitate and automate well abandonment procedures. In an embodiment, well field data for a plurality of wells is categorized into well types. An inspection set of wells, including wells of each type, is determined from the entire plurality of wells. Inspection data is collected for each well type, including environmental, regulatory, and well condition data. The inspection data is extrapolated onto wells with similar types for the entire filed and analyzed. The analysis may include determining an optimal sequence of well abandonment activities, and an estimate of costs for abandoning each well, all wells of each type, and the entire well field. In an embodiment, a risk assessment analysis is performed and may include an analysis of factors that may change the cost of abandoning the well field or a sequence of well abandonment activities.
摘要（中）：
系统和方法促进并自动完成放弃程序。 在一个实施例中，用于多个井的井场数据被分类为井类型。 从整个多个孔中确定包括各种井的井的检查集合。 为每种井类型收集检查数据，包括环境，监管和井况数据。 将检验数据外推到整个场地类似类型的井上并进行分析。 分析可以包括确定良好放弃活动的最佳顺序，以及放弃每个井，每种类型的所有井以及整个油田的成本估算。 在一个实施例中，执行风险评估分析，并且可以包括可以改变放弃井场的成本的因素的分析或一系列的放弃活动。
