As a partner in CUSP, the Washington Geological Survey (WGS, a division of the State of Washington Department of Natural Resources) will gather subsurface data on suitable storage reservoirs in Washington State by compiling and refining past reservoir mapping and improving reservoir property reporting through well log analysis. WGS will digitize the state’s heritage oil and gas well logs to increase efficiency of geologic interpretation and data-sharing. The goal of this work is to produce carbon sequestration prospect maps that may be used by the public, industry, and government agencies for planning carbon capture, utilization, and sequestration projects and reducing atmospheric CO2.

There are two main target plays for carbon sequestration in Washington State. In western Washington, Eocene sandstones are proven reservoirs for commercial gas storage and will be considered for CO2 injection. In eastern Washington enormous volumes of Miocene flood basalts are storage targets for permanent, mineralized carbon sequestration. Past work at Wallula, WA proves the practicality of injecting and mineralizing CO2 in the Columbia River Basalt Group.

WGS will also work to engage the public in project planning. Throughout this process, WGS is dedicated to considering health equity and social vulnerability in modeling project outcomes. WGS will also provide geological expertise to assist responsible agencies and industries in monitoring, reporting, and verifying CO2 sequestration.

WGS work in CUSP will help the State of Washington execute its future energy strategy while connecting the state to a network of sequestration options that benefit the entire CUSP region. Carbon sequestration is an important solution to the problem of anthropogenic climate change. We can solve this!
