Annotated G-function Plots from a Statistical Review of 225 Diagnostic Fracture Injection Tests from the Montney Shale

The Alberta Energy Regulator collects DFIT data from operators and makes it publicly available. We downloaded all available DFITs from the Montney shale and reviewed the plots to assess whether or not they show a ‘compliance’ closure response, as evaluated from the G-function plot. The results provided in this document will be presented in a paper at the February 2026 SPE Hydraulic Fracturing Technology Conference.阿尔伯塔能源监管局（Alberta Energy Regulator）从油气作业者处收集诊断压裂注入试验（Diagnostic Fracture Injection Test，DFIT）数据，并将其对外公开。我们从蒙尼页岩（Montney Shale）区块获取了全部可用的DFIT数据集，随后逐一研判相关曲线图，以G函数图（G-function plot）作为评估依据，判断这些数据是否呈现出“合规性”闭合响应。本数据集所载的分析结果，将在2026年2月举办的美国石油工程师协会（Society of Petroleum Engineers，SPE）水力压裂技术大会上以论文形式进行展示。
