Features combined integrated sensors for both Induced Seismic
and Microseismic monitoring over six orders of event
magnitude
HOUSTON, March 2, 2015 /CNW/ -- ESG Solutions, an
industry leader in microseismic technology and services has
released its latest generation of SuperCable™, a temporary downhole
array that now includes low frequency force-balance accelerometers
with 2Hz and/or 4.5 Hz geophone sensors in combination with
standard 15 Hz geophones, ensuring that over six orders of event
magnitudes can be detected. The SuperCable™ provides a
cost-effective alternative to traditional wireline array and
surface deployments, providing operators with the opportunity to
better understand activities in the reservoir, and their effects on
nearby surface infrastructure, at minimal cost and for extended
periods of time, from weeks to well over a year.
Microseismic monitoring effectively measures small-scale
micro-earthquakes during hydraulic fracturing; however typical
downhole microseismic geophones are not optimal for detecting
larger magnitude induced seismicity. The new generation of
SuperCable™ has sensors that can detect both larger and smaller
events down hole. Variable spacing of geophones allows for
the detection of small events with sensors situated close to the
reservoir, and larger events with sensors situated closer to
surface. SuperCable™ arrays are also moveable and
re-deployable, so they can be situated on or around pads to
optimize performance, and provide maximum detectability and
accuracy. Since SuperCable™ arrays are GPS time synchronized,
multiple deployments of the arrays can be used to monitor reservoir
activity in real-time.
ESG has recently deployed for several months multiple
SuperCable™ arrays to monitor large, multi-well pad completions in
North America, specifically in the
Marcellus and Utica
formations. High quality signals recorded by the SuperCable™
arrays resulted in significant additional data normally not
observed using traditional wireline and near-surface approaches,
thereby providing insight into the effectiveness of the stimulation
programs. According to Dr. Ted
Urbancic, Executive Vice-President of Global Energy Services
at ESG, "The data quality was so high it exceeded anything we have
ever recorded using temporary wireline arrays. The low noise
floor allowed for precise event locations to be obtained in
real-time, in addition to fulfilling ISM requirements and providing
verification of engineering designs." ESG has provided
microseismic monitoring services to the oil and gas industry for 15
years and continues to develop innovative solutions to meet the
industry's evolving needs, offering integrated solutions to clients
to ensure that they receive the maximum value from their
microseismic monitoring program.
