The injection of CO2 at the Decatur carbon capture and storage site has generated
significant microseismic activity, which occurs in distinct spatial clusters up to approximately …

The Farnsworth Unit in northern Texas is a field site for studying geologic carbon storage
during enhanced oil recovery (EOR) using CO 2. Microseismic monitoring is essential for …

In this work we describe a reprocessing technique to relocate microseismic events based on
the double-difference method. First, we use a crosscorrelation technique to assess …

The results of monitoring of carbon dioxide (CO 2) injection at the Illinois Basin—Decatur
Project (IBDP) and the companion Illinois Industrial Carbon Capture and Sequestration …

Sequestration of CO2 into subsurface reservoirs can play an important role in limiting future
emission of CO2 into the atmosphere (eg, Benson and Cole, 2008). For geologic …

The three‐year CO 2 injection period at the Illinois Basin‐Decatur Project site (Decatur,
Illinois, United States) produced a number of microseismic events distributed in very distinct …

Microseismic or passive seismic monitoring during hydraulic fracturing processes involves
recording 3C seismograms produced by microearthquakes associated with breaking rock …

Well fracturing or CO2 sequestration produces microseismic events that indicate the location
of the injected fluids, providing feedback on the stimulation objectives. This thesis provides …

I ncreases in pore pressure and volume caused by CO 2 injection will perturb the ambient
stress field and possibly trigger brittle failure on small fractures or faults, resulting in …

Simultaneously recording microseismic surface and borehole data (hereinafter referred to as
co-recorded data) offers some unique challenges. In many cases, timing differences …
