Improving source characterization microseismic events

项目摘要

The significant surge in hydrocarbon production from unconventional resources in the past decade**is largely due to the technological advances in horizontal drilling and hydraulic fracturing (i.e., fracking)**which made it possible to extract hydrocarbon from low-permeability (tight) reservoirs formerly**inaccessible or uneconomical to exploit. The Triassic Montney formation sitting on the Alberta-British**Columbia boundary, northwest of Edmonton, is considered one of North America's premier natural gas**resource plays, with the largest share owned by our industry partner Progress Energy Canada.**We propose to add values to the surface and downhole seismic recordings of microseismic events associated**with fracking by improving source characterization (location/origin time/mechanism) based on 3D seismic**background models. More accurate source locations will help refine the underlying fracture networks while the**additional source mechanism inversions can be used to indicate the brittle failure types in the reservoir in**response to stimulation. Furthermore, microseismic source mechanisms can be used to generate a set of**Discrete Fracture Networks (DFN) as input to reservoir geomechanical modelling, and enhance our**understanding on how the reservoir responds to fluid injection and stimulation, and enhance our industry**partner's ability to optimize the hydrocarbon production.

在过去十年中，来自非常规资源的碳氢化合物产量的显著激增 ** 主要是由于水平钻井和水力压裂的技术进步（即，水力压裂法）**，这使得有可能从以前 ** 无法进入或开采不经济的低渗透（致密）储层中提取碳氢化合物。位于埃德蒙顿西北部的艾伯塔-不列颠 ** 哥伦比亚边界的三叠纪Montney地层被认为是北美首屈一指的天然气资源之一，我们的行业合作伙伴Progress Energy Canada拥有最大的份额。我们建议通过基于3D地震背景模型改进震源表征（位置/起源时间/机制），为与压裂相关的微震事件的地面和井下地震记录增加价值。更准确的震源位置将有助于细化底层裂缝网络，而 ** 额外的震源机制反演可用于指示储层中响应于刺激的脆性破坏类型。此外，微震震源机制可用于生成一组离散裂缝网络（DFN），作为储层地质力学建模的输入，并增强我们对储层如何响应流体注入和增产的理解，并增强我们的行业合作伙伴优化油气生产的能力。
