Hydraulic fracturing is an important technical measure for coalbed methane (CBM) development, and the propagation of fractures in target coal seam induced by hydraulic related to stimulation performance CBM recovery. Therefore, effective monitoring fracture development during reservoir critical engineering. In this paper, microseismic technology was used monitor spatial temporal characteristics...

Coalbed methane (CBM) is a significant unconventional natural gas resource existing in matrix pores and fractures of coal seams cleaner energy compared to crude oil. To produce CBM, stimulation operations are required, given that the permeability generally too low. Hydraulic fracturing most widely used technology for reservoir stimulation; however, there few challenging issues associated with i...

[1] Hydraulic tomography is a cost-effective technique for characterizing the heterogeneity of hydraulic parameters in the subsurface. During hydraulic tomography surveys a large number of hydraulic heads (i.e., aquifer responses) are collected from a series of pumping or injection tests in an aquifer. These responses are then used to interpret the spatial distribution of hydraulic parameters o...

INTRODUCTION: The calculation of Manning n values has been of interest since the Manning equation was presented in the late 1800s (Henderson, 1966). While estimation of n vahm for normal channels has been fairly well standardized, the estimation of n values in areas of dense vegetation continues to be subject to large variations depending on the experience of the engineer and the perceived dens...

Hydraulic fracturing is the most widely used primary method for stimulation of unconventional oil and gas resources. While knowledge hydraulic fracture parameters critical to reservoir productivity, predicting initiation important determining complexity network. Subcritical crack growth in rock plays an role forming networks, but understanding influence conditions on subcritical still lacking. ...

This paper describes a new modeling framework for microscopic to reservoir-scale simulations of hydraulic fracturing and production. The approach builds upon fusion two existing high-performance simulators behavior: the GEOS code hydromechanical evolution during stimulation TOUGH+ multi-phase flow are informed by experimental studies at laboratory scale incorporate important micro-scale mechani...
