基于地球化学的生产监测和分配方法比使用生产测井工具的成本低得多，因为井场不需要额外的钻机时间或额外的人员。此外，无需干预油井碳氢化合物的生产，从而降低了操作风险。完整的论文总结了这些方法，并提供了示例并描述了避免一刀切方法的最佳实践。
石油地球化学的产量分配在此被定义为基于流体化学在特定时刻分配给两个或多个单独流体源的混合流体的量或部分的定量确定。它需要在混合之前了解每种流体的原始化学成分（此处称为“最终成员”），并能够识别其化学成分的统计上有效的差异。
Geochemical-based methods for production monitoring and allocation are much lower-cost than use of production logging tools because no additional rig time or extra personnel are required at the well site. Additionally, no intervention to the production of hydrocarbons from a well is required, reducing operational risk. The complete paper summarizes these approaches and provides examples and describes a best practice that avoids a one-size-fits-all approach.
Production allocation from petroleum geochemistry is defined here as the quantitative determination of the amount or portion of a commingled fluid to be assigned to two or more individual fluid sources at a particular moment in time based on fluid chemistry. It requires knowledge of the original chemical compositions of each of the fluids before mixing (referred to here as the “end members”) and the ability to identify statistically valid differences in their chemistries.
