CO2 Sequestration and Enhanced Oil Recovery at Depleted Oil/Gas Reservoirs

Enhanced Oil Recovery and CO2 Flooding/Sequestration in Carbonates

Electromagnetic Imaging of CO2 Sequestration at an Enhanced Oil Recovery Site

Lawrence Livermore National Laboratory (LLNL) is currently involved in a long term study using time-lapse multiple frequency electromagnetic (EM) characterization at a waterflood enhanced oil recovery (EOR) site in California operated by Chevron Heavy Oil Division in Lost Hills, California (Figure 1). The petroleum industry’s interest and the successful imaging results from this project suggest...

Sequestration of CO2 in a Depleted Oil Reservoir: An Overview

Geologic sequestration of CO2 in depleted oil reservoirs, while a complex issue, is thought to be a safe and effective carbon management strategy. This paper provides an overview of a NETLsponsored R&D project to predict and monitor the migration and ultimate fate of CO2 after being injected into a depleted oil reservoir as part of a micropilot scale field experiment. The Queen Formation sandst...

Risk assessment for future CO2 Sequestration Projects Based CO2 Enhanced Oil Recovery in the U.S

This paper is the first of a series that attempts to assess the possible health and safety risks associated with large scale CO2 sequestration in deep brine reservoirs. The approach is based on analysis of available data on the operational track record from CO2 transportation and injection associated with enhanced oil recovery (CO2-EOR) in the US. This paper is particularly concerned with ident...
