项目摘要

Microseismic events are very small earthquakes, which can be generated through anthropogenic influences on sub-surface geologic reservoirs. Even though the magnitude of these events is usually only equivalent in energy to that of breaking a pencil, these events provide a detailed description of how the rock is fracturing and where fluids may be flowing. There are number of application of monitoring microseismic events, including shale-gas stimulation (fracking), CO2 storage, waste-water disposal and geothermal engineering. Shale-gas in particular has been an economic game changer in the USA, but increasingly regulators are requiring microseismic monitoring of injection operations. The market for this technology is growing quickly - less than 5% of fracking operations are monitored in the USA, but it highly likely that all European fracking operations will be required to have microseismic monitoring. Bristol University has been doing research in this area for the past 10 years and is ahead of the curve in technology, as the industry norm is to simply locate events. Event locations are useful, but are often not a good indicator of the efficacy in fluid stimulation - fracking often fails. To address this, we have developed a suite of software that characterises the seismic source, monitors fracture network development, and holds the potential to track fluid migration through the subsurface. This will identify untapped regions and guide subsequent treatments. A significant market advantage is our aim for automated real-time monitoring. This technology also plays an important environmental monitoring role, as it can be used to inform regulatory procedures that will limit potentially damaging operations in unfavourable environments (high pre-existing stress). The proposed project will link a series of research-grade programmes into a commercial-grade software package. This will provide the software to implement a best-practice for monitoring induced-seismicity. We have good links with the industry and potential clients, and have expressions of interest from a larger seismic acquisition company looking to move into the microseismic monitoring, a SME with experience in borehole operations but not microseismic monitoring, and a mid-size company interested in monitoring baseline seismicity in regions of shale-gas exploration.

微震事件是一种非常小的地震，它可以通过人为影响地下地质储集层而产生。尽管这些事件的强度通常只相当于折断一支铅笔的能量，但这些事件详细描述了岩石是如何破裂的，流体可能在哪里流动。监测微震事件有许多应用，包括页岩气刺激(水力压裂)、二氧化碳储存、废水处理和地热工程。页岩气尤其改变了美国的经济游戏规则，但监管机构越来越多地要求对注入作业进行微地震监测。这项技术的市场正在迅速增长--美国只有不到5%的水力压裂作业受到监控，但欧洲所有水力压裂作业都极有可能被要求进行微地震监控。布里斯托尔大学在过去10年里一直在这一领域进行研究，并在技术上走在了前列，因为行业规范是简单地定位事件。事件地点是有用的，但往往不是流体刺激效果的良好指标-水力压裂经常失败。为了解决这一问题，我们开发了一套软件，该软件描述了震源的特征，监控裂缝网络的发展，并具有追踪地下流体运移的潜力。这将确定未开发的区域，并指导后续的治疗。我们的目标是实现自动化实时监控，这是我们的一个重要市场优势。这项技术还发挥着重要的环境监测作用，因为它可以被用来为监管程序提供信息，以限制在不利环境(先前存在的高压力)中可能造成破坏的作业。拟议的项目将把一系列研究级别的课程连接成一个商业级别的软件包。这将为实施监测诱发地震活动的最佳做法提供软件。我们与业界和潜在客户有着良好的联系，并有一家希望进军微地震监测领域的较大地震采集公司、一家拥有井眼操作经验但没有微地震监测经验的中小企业以及一家对监测页岩气勘探地区基线地震活动感兴趣的中型公司表示有兴趣。
