Carbon Dioxide Storage and Sequestration in Unconventional Shale Reservoirs

Carbon Dioxide Storage in Natural Gas Reservoirs

Carbon Dioxide Storage in Natural Gas Reservoir — The general idea of CO2 disposal in gas reservoirs is that the underground volume of the ultimately recoverable hydrocarbons (gas and condensate) is replaced by CO2. This paper investigates the feasibility of carbon dioxide disposal in depleted gas reservoirs. Gas reservoirs are a practical storage site for the carbon dioxide, because the presen...

Carbon sequestration in leaky reservoirs

We propose in this paper a model of optimal Carbon Capture and Storage in which the reservoir of sequestered carbon is leaky, and pollution eventually is released into the atmosphere. We formulate the social planner problem as an optimal control program and we describe the optimal consumption paths as a function of the initial conditions, the physical constants and the economical parameters. In...

Sequestration of Carbon Dioxide Emissions

Background The world's oceans represent the largest potential sink for the carbon dioxide (CO 2) produced by human activities (anthropogenic CO 2). Already oceans contain the equivalent of an estimated 140,000 gigatons of CO 2. The ocean's natural carbon transfer processes span of thousands of years and will eventually transfer 80-90 percent of today's man-made CO 2 emissions to the deep ocean....

Reductive Sequestration of Carbon Dioxide

The United States currently meets 80% of its energy needs by burning fossil fuels to form CO2. The combustion-based production of CO2 has evolved into a major environmental challenge that extends beyond national borders and the issue has become as politically charged as it is technologically demanding. Whereas CO2 levels in the atmosphere had remained stable over the 10,000 years preceeding the...
