Seismic data
I confirm that I have read and accepted this dataset's licence requirements.
Description
This dataset contains three parts: a high resolution 3D seismic survey, timelapse vertical seismic profiling, passive seismic events.
IBDP_3D_Seismic_Volume_Reprocessed
Illinois State Geological Survey (ISGS), Illinois Basin - Decatur Project (IBDP) 3D Seismic Reflection Volumes, June 28, 2021. Midwest Geological Sequestration Consortium (MGSC) Phase III Data Sets. DOE Cooperative Agreement No. DE-FC26-05NT42588.
The high-resolution 3D seismic survey acquired in January 2015 was reprocessed in August 2019 to improve the resolution needed to identify and mapped faults in the subsurface.
This file contains:
- isgs-Inversion.pdf describes the processing workflow and results
- decature3d-loadsheet.xlsx parameters for loading the seismic volume into software for viewing and interpretation.
The 3D seismic reflection final processed volumes are in the subfolder Depth-PSTM:
- PSTM depth volume, PSTM phase-shifted volume, Acoustic impedance volume, and porosity volume.
IBDP_3D_VSP_Reprocessed
Illinois State Geological Survey (ISGS), Illinois Basin - Decatur Project (IBDP) Vertical Seismic Profile, July 7, 2021. Midwest Geological Sequestration Consortium (MGSC) Phase III Data Sets. DOE Cooperative Agreement No. DE-FC26-05NT42588.
Time Lapse VSPs were acquired to provide information on CO2 plume development. Six 3D VSP surveys were acquired at the IBDP site: two baseline surveys and four monitoring surveys. The VSP data was reprocessed in 2019. One high-resolution image was created by combining the Baseline 2 and Monitor 1 surveys.
The contents of the folder 3D_VSP_Reprocessed:
- 2019-08-26_ISGS_Decature3DVSP_update.pdf describes the processing processing workflow and results
- Final 3D VSP Depth volume
- Final 3D VSP Time volume
The geometry files for the two volumes are in the subfolder "geometry files"
IBDP_Passive_Seismic_Events_Monitoring
The contents of the folder Passive_Seismic_Events_Monitoring are:
- IBDP_20130106_PreInjection_Microseismic_Report.pdf
- IBDP_201710_Velocity_Model_Calibration2_Report2.pdf
- IBDP_201907_Report_microseismic_monitoring_geophones_procedures_catalogue_chronology.pdf
- Downhole geophone data
- Surface seismometer data
