Hydraulic Fracturing: Improved Engineering of Unconventional Shale Reservo
irs\n\n\n \n\nHydraulic fracture stimulations are critical for the develop
ment of unconventional reservoirs, and the growing interest in shale reser
voirs has resulted in the rapid expansion of microseismic fracture imaging
. During high-pressure fluid injections of a hydraulic fracture treatment,
microseismic emissions occur as cracks form and interact with pre-existin
g fractures. Images of the microseismic locations can be used to interpret
hydraulic fracture geometries, including the direction, dimensions, and c
omplexity resulting from networks of fractures in different orientations.
The course will provide an overview of microseismic theory and practical a
pplication: from acquisition and survey design, processing through to inte
rpretation. The emphasis will be on practical issues associated with acqui
sition of high-quality microseismic data, including potential pitfalls and
quality control steps. Actual case studies will be used to demonstrate en
gineering benefits and improved production through the use of microseismic
.\n\nWho should attend?\nThe course is intended for geophysicists, enginee
rs and geologists. The emphasis is on practical application and, as such,
only basic prerequisite knowledge is assumed. The course would be most rel
evant to those currently involved with, or considering development of, unc
onventional reservoirs and particularly shales.\n\nCourse Objectives\nStud
ents will gain an understanding of the theoretical and practical aspects o
f microseismicity, including how to use data to improve engineering design
of hydraulic fractures, as well as:\n\n Basics of hydraulic fracture oper
ations\n Geomechanical processes that generate microseismicity, and how it
relates to the hydraulic fracture growth\n Issues associated with high-qu
ality microseismic data\n Common processing pitfalls and quality control a
pproaches to processing workflows\n Identifying and accounting for potenti
al monitoring biases\n Interpretation of microseismic images\n Application
of microseismic data to fracture engineering challenges\n Monitoring-indu
ced seismicity\n\nSummary\nThe following topics will be addressed in the c
ourse:\n\n Introduction and History of Microseismic Monitoring:\n A review
of the history of microseismic applications, including mining-induced sei

ith the contamination of shallow aquifers and induced seismicity.\n Hydrau
lic Fracturing Basics:\n A tutorial of fracture mechanics theory, field op
erations and equipment, diagnostic technologies, and factors that influenc
e hydraulic fracture growth. The review describes engineering challenges a
ssociated with designing an effective hydraulic fracture treatment ,and pr
ovides a context for practical application of microseismic imaging through
the remainder of the course.\n Acquisition and Pre-Survey Design:\n Vario
us microseismic monitoring configurations are described, including vertica
l, horizontal and multi-well downhole, surface, and shallow buried arrays.
Pros and cons of each configuration are described along with acquisition
system specifications and the impact on microseismic data quality. Essenti
als of survey design for both surface and downhole monitoring are given, a
long with criteria for designing an optimal monitoring system.\n Basic Pro
cessing for Microseismic Locations:\n Basis processing of microseismicity
involves estimating the hypocentral location of the microseismic sources a
long with uncertainty estimates. A standard processing workflow is describ
ed, including velocity model construction and calibration. Standard locati

ic source characterization.\n Interpretation of Microseismic Fracture Imag
es:\n Assessment of sensitivity, resolution, and confidence of microseismi
c images is reviewed. Workflows are described to remove potential biases a
nd improve the accuracy of the microseismic events. Assessment of fracture
direction, dimensions, complexity and stimulated volume from microseismic

other information is stressed to provide geologic and geomechanical interp
retation frameworks.\n Engineering Applications of Microseismic Imaging:\n
Presentation of case studies demonstrating various aspects of improving e
ngineering designs for hydraulic fracture stimulations, well completions a

ove the engineering design. The value of information considerations are de
scribed along with improving the economic viability of unconventional deve
lopments using microseismic imaging to increase productivity and reduce we
ll, completion, and stimulation costs and designs using microseismic data.

Hydraulic fracture sti

nd the growing interest in shale reservoirs has resulted in the rapid expa
nsion of microseismic fracture imaging. During high-pressure fluid injecti
ons of a hydraulic fracture treatment, microseismic emissions occur as cra
cks form and interact with pre-existing fractures. Images of the microseis
mic locations can be used to interpret hydraulic fracture geometries, incl
uding the direction, dimensions, and complexity resulting from networks of
fractures in different orientations. The course will provide an overview
of microseismic theory and practical application: from acquisition and sur
vey design, processing through to interpretation. The emphasis will be on
practical issues associated with acquisition of high-quality microseismic
