Abstract
An extensive b-value power law analysis is carried out on a large dataset of microseismic events accumulated from over 300 stages during the hydraulic fracture treatment of three wellpads in the Horn River basin. This analysis is carried out on three different length scales: the single stage level, the level of the formation and finally in a 3D volume. A comparison of three commonly used statistical methods of analysis is carried out at the stage level to determine the statistical validity of these methods.
B-value analysis is a form of statistical analysis which is highly sensitive to the statistical methods being employed as well as the size of the data sample. B-values themselves are not a completely self-sufficient and quantitative description of the stress state of the medium but must be combined with other observations involving other geoscience methods such as seismic and well-log analysis along with engineering data.
