Cape EGS: Frisco 2-P Well Stimulation Microseismic Data

This dataset contains microseismic data acquired during the Frisco 2-P well stimulation project led by Fervo Energy, conducted between June 1 and June 11, 2024, near the Utah FORGE geothermal site. The microseismic data was collected from various Utah FORGE wells: via Distributed Acoustic Sensing (DAS) fiber in 16B, and three 3-component geophones located in wells 56-32, 78B, and 32. The dataset is structured in SEGY format, where the first nine traces represent data from the geophones, and the remaining traces capture DAS data from well 16B.

Each SEGY file in this dataset contains triggered microseismic events, with event initiation based on Short-Time Average over Long-Time Average (STA/LTA) detection criteria during the stimulation process. Files are grouped by time intervals and named following the structure "[WellPad][WellName][Month]_[Year]Divine_Trigger[EventNumber].sgy," indicating well pad, well name, date, and event number. Sampling parameters include a spatial sampling of approximately 2 meters for DAS channels and a temporal sampling rate of 2000 Hz, with each data record spanning 1.2 seconds. The files' coordinates are referenced to the location of the FORGE 16A-32 wellhead, positioned at UTM coordinates: Easting 334641.1891 m and Northing 4263443.693 m. The geographic coordinates for this origin are 38.50402147 latitude and -112.8963897 longitude, with an elevation of 1650.0249 meters above sea level.

本数据集收录了Fervo Energy领导下的Frisco 2-P井刺激项目在2024年6月1日至6月11日期间，于犹他州FORGE地热站附近获取的微地震数据。微地震数据由多个犹他州FORGE井提供：通过16B井的分布式声学传感（DAS）光纤收集，以及位于56-32井、78B井和32井的三分量地震计收集。数据集采用SEGY格式组织，其中前九个迹线代表地震计数据，其余迹线则捕捉16B井的DAS数据。每个SEGY文件均包含触发微地震事件，事件启动基于刺激过程中的短时平均/长时平均（STA/LTA）检测标准。文件按时间间隔分组，并按以下结构命名：“[井场][井名][月份]_[年份]Divine_Trigger[事件编号].sgy”，以标示井场、井名、日期和事件编号。采样参数包括DAS通道的空间采样约为2米，时间采样率为2000赫兹，每个数据记录跨度为1.2秒。文件的坐标参照FORGE 16A-32井口位置，位于UTM坐标：东经334641.1891米和北纬4263443.693米。该起点的地理坐标为纬度38.50402147，经度-112.8963897，海拔高度为海平面以上1650.0249米。
