... Abstract Throughout the past decade, much discussion and debate have centered on geological sequestration of carbon dioxide (CO 2 ). In order for sequestration to have a reasonably positive impact on atmospheric carbon levels, the anticipated volume of CO 2 that would need to be injected...

... Abstract Chemical interactions between CO 2 /brine/rock can cause formation damage during CO 2 injection. These interactions can affect injectivity during EOR operations, as well as affect storage capacity and seal integrity, which are primary concerns during CO 2 sequestration...

... Abstract On 25 July 2008, US Environmental Protection Agency (EPA) proposed a rule governing carbon dioxide (CO 2 ) sequestration wells, e.g., newly EPA designated Class VI wells. The Agency cites many references regarding Enhanced Oil Recovery (EOR) wells, but demonstrates a lack of applying...

... Abstract Although CO 2 geological sequestration is the most popular carbon storage method promoted and pilot tested, the economic feasibility and technical risks for commercial scale sequestration projects are rarely mentioned. More significant is that, apart from rhetorical pronouncements...

... Abstract This paper investigates the economic feasibility of extending the production life of a small mature oilfield using EOR coupled with CO 2 sequestration. We describe the physical aspects of this project, as well as, present a breakdown cost methodology in order to estimate the main...

..., naturally occurring potential store for CO 2 . Although there are a number of mathematical modeling studies related to injection of CO 2 in deep saline aquifers, experimental studies are limited and most studies focus to sandstone aquifers as opposed to carbonate ones. Potential CO 2 sequestration...

... Abstract Our previous coreflood experiments - injecting pure CO 2 into carbonate cores - showed that the process is a win-win technology, sequestrating CO 2 while recovering a significant amount of hitherto unrecoverable natural gas that could help defray the cost of CO 2 sequestration...

... ABSTRACT Two similar Tertiary gas fields in the North Sea produce relatively rich gas condensate with a high proportion (4.5%-9%) of carbon dioxide (CO 2 ) in the gas. The objective of this study was to evaluate the potential for CO 2 sequestration in high permeability sandstone above the main...

... or 68% OGIP (80-acre pattern). Third, at $2.00/MSCF, produced gas revenue amounts to about $2.6 million to $9.8 million, which could help defray the cost of CO 2 sequestration. In short, CO 2 sequestration in depleted gas reservoirs appears to be a win-win technology. recovery factor...

...) use and food grade (that requires highly pure CO 2 stream) use from a raw natural gas containing 65% CO 2 by volume 5 . Membrane Abstract Geological sequestration is a potential technology to reduce large amount of greenhouse gas emissions which are essentially carbon dioxide (CO 2...

... into aquifers. A survey of minerals commonly encountered in crustal rocks was made to identify possibilities for chemical sequestration of CO2 through the formation of carbonates of low solubility. We also performed batch reaction modeling of the geochemical evolution of representative aquifer mineralogies...

... Abstract A goal of CO 2 sequestration is to provide economically competitive and environmentally safe options to offset projected growth in baseline emissions of greenhouse gases. The sequestration of CO 2 in subsurface formations is a gas storage process. Among the issues that must...

... Abstract CO 2 Sequestration has been proposed as a possible means of achieving sustainable development objectives and calls upon petroleum industry technology and expertise. Commercial application of long-term CO 2 sequestration depends in large part on the ability to effectively model...
