WESTCARB has created educational videos to better share our work on carbon capture, utilization, and storage. See us in action!
| Citizen Green Well Project |

In late 2011, WESTCARB drilled a well in the Sacramento Basin of California in order to characterize the CO2 storage potential of regionally extensive geologic formations. |
| From Field to Laboratory: Qualifying a Geological CO2 Storage Site |
|
From Field to Lab, Part 1: Introduction
At a geologic characterization well, researchers obtain downhole measurements and preserve rock and fluid samples for laboratory analyses. Their findings help determine if a site can safely store CO2 that would otherwise be emitted to the atmosphere. |
 |
From Field to Lab, Part 2: Logging the Well
At a geologic characterization well, researchers conduct mud logging and wireline logging to ascertain the properties, depths, and thicknesses of rock formations that can contain CO2. |
 |
From Field to Lab, Part 3: Isotope Geochemistry Analysis of the Core Samples
Noble gases from the pores of rock samples are analyzed at Lawrence Berkeley National Lab to determine if the rocks show a history of gas containment, indicating the potential for secure, long-term CO2 storage. |
 |
From Field to Lab, Part 4: Reacting CO2 with Rock Cores
Researchers at Lawrence Berkeley National Lab expose rock samples from potential CO2 storage reservoirs to carbonate-rich fluids and measure whether minerals are precipitating or forming. Understanding the impact of these processes on permeability and porosity helps determine if a potential site is suitable for CO2 storage. |
 |
From Field to Lab, Part 5: CT Scanning to Study Fluid Flow in Rock Cores
Researchers at Lawrence Berkeley National Lab use seismic waves and X-ray CT scanning to understand fluid flow in rock samples. Their measurements can be used in the field to monitor CO2. |
 |
From Field to Lab, Part 6: Micro-Imaging Rock Pore Spaces
Lawrence Berkeley National Lab researchers use micro-imaging techniques to map the geometry of pores in rock samples in order to determine how well CO2 will fill the pores in a CO2 storage application. |
