本文详细分析了水力压裂微震活动和工程数据，在联合运营商棉花谷水力压裂成像项目在得克萨斯州东部。该项目是一个联合运营商联盟，目标是评估常规加砂压裂和含砂量极低的水力压裂的水力裂缝生长。在三口威尔斯井的十个裂缝阶段使用了各种裂缝诊断工具，包括微地震和井下倾斜仪裂缝绘图、裂缝建模、应力测试、放射性示踪剂、压力瞬变试井和生产测井。我们还介绍了一种方法，使用全三轴波形分析的微震信号，以获得震源参数，在水力压裂过程中的故障模式的特征。该信息可能用于裂缝几何形状、生长和复杂性的详细描述，并且可能给出关于创建的裂缝长度与支撑的裂缝长度的一些指示。本文将微地震产生长度和支撑长度与压裂模型计算结果进行了比较。
This paper presents detailed analyses of hydraulic fracture microseismicity and engineering data created during the joint operator Cotton Valley Hydraulic Fracture Imaging Project in East Texas. The project was a joint operator consortium with the goal of evaluating hydraulic fracture growth of conventional sandfracs and waterfracs with very low sand concentrations. A variety of fracture diagnostic tools were used on ten fracture stages in three wells including microseismic and downhole tiltmeter fracture mapping, fracture modeling, stress tests, radioactive tracers, pressure transient well tests, and production logging. We also introduce a methodology that uses full triaxial waveform analysis of the microseismic signals to obtain seismic source parameters, which characterize failure modes during hydraulic fracturing. This information could potentially be used for a detailed description of fracture geometry, growth and complexities and may give some indications about created versus propped fracture lengths. The paper compares the microseismic created lengths and propped lengths with those from frac models.
