T/CSES 71-2022 Geological Utilization and Storage of Carbon Dioxide Project Leakage Risk Evaluation Specification
Basic Information
Scope
Scope: This document specifies the identification of leakage risks and environmental baseline surveys for CO2 geological utilization and storage projects, CO2 leakage risk analysis, CO2 leakage risk grading, and monitoring requirements. This document is applicable to the leakage risk assessment during the site selection and design phase of CO2 geological storage, CO2 flooding for enhanced oil recovery, and CO2 displacement of coalbed methane, etc. involving CO2 injection into the ground. Similar projects currently under construction or operation can also refer to and use this document for reference; Main technical content: The main content of this standard includes an overview of CO2 leakage risk assessment, CO2 leakage risk identification and environmental baseline surveys, CO2 leakage risk analysis, CO2 leakage risk grading, and monitoring requirements. This standard aims to provide normative guidance for the CO2 leakage risk assessment of CCUS projects in China and provide a basis for the formulation of CO2 leakage monitoring plans.
