“…It uses a pattern of high density, high resolution 18 Hz geophone accelerometers in order to give the maximum amount of fl exibility in attenuating the high levels of noise contamination while maintaining high frequency bandwidth during processing. 7,8 Th e 60 000 lb (27 216 kg) vibrator trucks used an MD Sweep* maximum displacement sweep design methodology that provides the most energetic low frequencies possible from the vibrator and runs from 4 to 100 Hz to maximize the low frequency content in the dataset. 9 Obtaining seismic data with frequencies between 2 to 10 Hz is particularly useful for inversion analysis, as it can be used to build a more robust low frequency model that is less biased by sparse well log data.…”

The Illinois Basin -Decatur Project (IBDP) is a carbon capture and storage (CCS) project that is located at the Archer Daniels Midland (ADM) Company's corn processing plant in Decatur, Illinois. The IBDP has an extensive seismic program that was designed to meet site characterization and monitoring objectives that includes two-dimensional (2D) and three-dimensional (3D) surface seismic data, time-lapse 3D vertical seismic profi les (VSPs), and microseismic monitoring. As little deep subsurface data was available within a 20-mile (32-km) radius of site, the surface seismic surveys have been important to the site characterization objectives for the project. Through seismic inversion analysis, rock properties such as density, porosity, and rock lithology were derived from the surface seismic data and incorporated into the geologic and geomechanical models for the project. Time-lapse 3D VSPs are acquired with a permanent geophone array in Geophysical Monitoring Well #1 (GM1). Carbon dioxide (CO 2 ) injection commenced in November 2012, and the fi rst monitor survey was acquired in February 2012 after approximately 70 000 tonnes of CO 2 had been injected. While this is a small volume of CO 2 to detect seismically, anomalies were identifi ed that may be suggestive of CO 2 movement in the Mt Simon Sandstone at the depth of injection. Microseismic activity has been monitored using the geophone array in GM1 and two deep geophones installed in the Injection well (CCS1). A comparison of the different operation parameters with microseismic activity shows a correlation between microseismicity and pressure changes in the formation.
