对于地质学家和工程师来说，准确的储层表征通常是经济成功与失败的区别。减少油藏不确定性的主要工具之一是钻杆测试（DST），它提供有关油藏地层压力和流体特征的关键信息。
通过 TGS 井数据分析进行的 TGS 钻杆测试是地球科学家和油藏工程师表征整个盆地地层压力的宝贵工具。压力梯度的空间变化会对生产预测模型产生重大影响，并决定钻探计划的成败。压力梯度还可以揭示潜在的水处理场和被忽视的投资机会。
在本期 Well Intel 中，我们展示了利用特拉华盆地 DST 压力数据的工作流程。该工作流程可以作为关键的储层表征工具在美国各地的许多其他盆地和生产地层中复制。

For geologists and engineers, accurate reservoir characterization is often the difference between economic success and failure. One of the main tools to reduce reservoir uncertainty is drillstem tests (DSTs), which provide key information about formation pressure and fluid characteristics of the reservoir.
TGS drillstem tests, available through TGS Well Data Analytics, are an invaluable tool for geoscientists and reservoir engineers to characterize formation pressure across a basin. Spatial variability of pressure gradients can have a significant impact on production forecasting models and make or break a proposed drilling program. Pressure gradients can also reveal potential water disposal sites and overlooked investment opportunities.
In this edition of Well Intel, we showed a workflow for utilizing pressure data from DSTs in the Delaware Basin. This workflow can be replicated in many other basins and productive formations across the US as a key reservoir characterization tool.
