Database

About the database

The GIS CCUS Brazil Platform brings together information from various public data sources into a robust and integrated database. The vector data was processed to display relevant information, providing a comprehensive and detailed view of strategic decision-making on CCUS. This data has been organized into the following categories: Emission Sources, Infrastructure and Logistics, Areas Subject to Protection or Restrictions, Exploratory Data, Sedimentary Basins, CO2 Storage Resources, Storage Resources Management System (SRMS), and CCUS Projects in Brazil.

The database includes emission data from more than 1,500 CO2 sources from the hard-to-abate sector and energy industry. Additionally, it features around 18,000 infrastructure and logistics elements and more than 370,000 restrictive or protected areas. The analysis of CO2 geological storage potential in Brazilian sedimentary basins integrated data from 30,621 exploratory wells, 14,900 geophysical surveys, as well as geological and geothermal information from 72 onshore and offshore sedimentary basins, consolidating hundreds of layers that illustrate the distribution and thickness of elements in the CO2 storage systems, with a focus on the volumetric capacity of saline water and depleted hydrocarbon reservoirs.

CO2 Emission Sources

CO2 emission sources are classified as either stationary, such as industries and power plants, or non-stationary, such as vehicles. Stationary sources are particularly relevant for CCUS projects due to their large emissions and fixed locations, making them ideal for efficient CO2 capture and storage.

Therefore, in alignment with the GIS CCUS Brazil Platform's objectives, the CO2 emission source mapping primarily focuses on stationary sources. The following sectors were considered for the database:

  • Energy, including the biofuels production (ethanol, biodiesel, and biomethane), thermoelectric power plants, as well as plants that are part of the Isolated System (not interconnected with the National Interconnected System);
  • Hard-to-abate industries, such as refineries, petrochemicals, cement, steel (iron and steel), and fertilizers;
  • Other industries, such as metal factories (aluminum and zinc production), food and beverage, and pulp and paper.

CO2 emission source mapping was updated based on Ketzer et al., 2016, using government databases, such as those from the Brazilian National Agency of Petroleum, Natural Gas and Biofuels (ANP) and the Energy Research Office (EPE), along with data released by industrial or producer associations and documents available online.

Emissions quantification from the energy, biofuels, and hard-to-abate sectors used two approaches. The first involved accessing online information in consolidated databases, including the Public Emissions Registry, from the Getúlio Vargas Foundation and Brazil GHG Protocol, and the Climate Trace website. The second approach involved calculating emissions based on production data and specific emission factors for each activity, obtained through the IPCC (2006) and MCTIC (2016).

More detailed information on the specific methodologies adopted for each sector can be found in the methodology document (coming soon).

Potential CO2 Reservoirs

Data Source

The development of the subsurface database involved the download and manipulation of data from various databases and platforms. Exploratory wells and seismic surveys were sourced from the Revitalization of Exploration and Production Activities in Onshore Areas (REATE) and Revitalization and Incentive for Production of Offshore Fields (PROMAR) programs, conducted by the Geological Survey of Brazil (CPRM-SGB) and the National Agency of Petroleum, Natural Gas, and Biofuels (ANP). Lithology, structural data, and non-seismic geophysical surveys were provided by the National Mining Agency (ANM) and CPRM-SGB. Additionally, the database includes information on exploratory blocks, production fields, and Pre-Salt boundaries (ANP), mining titles (ANM), and sedimentary basins (CPRM-SGB).

CO2 Storage Resources

The analysis of storage potential in geological formations within Brazilian sedimentary basins led to the creation of vector layers for CO2 storage resources. These layers include basalts, coal deposits, saline water reservoirs, and depleted hydrocarbon reservoirs, detailing for the latter two types the depths of formation tops, reservoir thicknesses, and volumetric storage capacity. This comprehensive analysis was enabled by integrating data from over 30,000 exploratory wells, geophysical surveys, and geological and geothermal data from 72 onshore and offshore sedimentary basins. In our analysis of storage resources related to saline water reservoirs, we excluded intervals used for groundwater intended for human consumption, such as the Guarani Aquifer (Botucatu Formation), among others.

CO2 Storage Resources Management System (SRMS) in Brazil

The SRMS project classification system is based on the internationally recognized classification system widely used in the energy industry, the Petroleum Resources Management System (PRMS), both developed by the Society of Petroleum Engineers (SPE). The SRMS methodology standardizes the evaluation and feasibility of implementing CCUS projects, considering technical, economic, legislative parameters, and the characterized subsurface potential. This methodology was employed in the development of the CCUS Brazil GIS Platform, to apply and adapt its concepts to create a classification of CO2 geological storage resources for Brazilian sedimentary basins.

More detailed information on the specific methodologies adopted in data manipulation, storage resource characterization, and the SRMS classification system can be found in the methodology document (coming soon).

Infrastructure and Logistics

The analysis of infrastructure data supports the decision-making process for the implementation of CCUS projects. These geospatial data include power transmission lines, substations, pipelines, oil, gas, and derivative terminals, transportation networks (highways, railways, and waterways), port facilities, and natural gas delivery and processing sites, among others. The main sources of national infrastructure vector data consulted were the Transport Information Database (BIT), EPE, CPRM-SGB, and ANP. Through the manipulation of these data, vector layers were generated and made available on the CCUS Brazil GIS Platform.

Protected and restrictive areas

Data related to protected areas and restrictive areas is presented on the CCUS Brazil GIS Platform, as these represent potential points of concern or restriction for CO₂ subsurface storage. Protectable areas include Permanent Preservation Areas, Quilombolas Territories, Indigenous Lands, Conservation Units, and the locations of water supply wells. Restrictive areas encompass the safety zones of power transmission lines. The database was constructed by integrating geospatial data provided by public sources. The data sources used in this survey include SIAGAS/CPRM-SGB, the Brazilian Institute of Geography and Statistics (IBGE), the National Rural Environmental Registry System (SiCAR), the Chico Mendes Institute for Biodiversity Conservation (ICMBio), and EPE. Only areas within the boundaries of Brazilian sedimentary basins are presented.
