The Enhanced Oil Recovery (EOR) method aims to increase oil production. One of the EOR methods is CO2 injection. injection mechanism by expanding volume oil, reducing viscosity, and mobility ratio. purpose study was compare recovery factor gain in waterflood, Miscible Continuous injection, WAG with a three-dimensional simulation methodology using CMG Compositional software CW Field. From field,...

core flooding experiments were conducted with the objective of evaluating near miscible surfactant alternating co2 injection and the effect of surfactant concentrations on gas-oil and water displacements in porous media. the core samples were provided from a low permeability mixed wet oil reservoir at 156 °f and 1900 psia. in addition, very few studies of surfactant adsorption on carbonate mine...

The direct disposal of CO2 into the ocean interior represents a possible means to help mitigate rising levels of atmospheric CO2. Here, we use three different versions of an ocean general circulation model (OGCM) to simulate the direct injection of liquid CO2 near Tokyo. Our results confirm that direct injection can sequester large amounts of CO2 from the atmosphere when disposal is made at suf...

Glossary Carbon sequestration: capture and secure storage of carbon that would otherwise be emitted to or remain in the atmosphere. Carbon sources: for this chapter, we are concerned with large stationary sources of CO2, e.g. fossil fueled power plants, cement manufacturing, ammonia production, iron and non-ferrous metal smelters, industrial boilers, refineries, natural gas wells. Carbon captur...

Developing a method for secure sequestration of anthropogenic carbon dioxide in geological formations is one of our most pressing global scientific problems. Injection into deep-sea basalt formations provides unique and significant advantages over other potential geological storage options, including (i) vast reservoir capacities sufficient to accommodate centuries-long U.S. production of fossi...

The Sim-SEQ project coordinated by the Lawrence Berkeley National Laboratory (LBNL) aims at providing a comparative study of different conceptual models with respect to predicting the behavior of CO2 geological storage operations conducted on a reservoir formation, while using the same database for site characterization. The S-3 site has been selected for conducting such a comparative study. Al...

nowadays biodiesel is receiving more attention as a most important renewable energy for using in diesel engines. inthis research, the application of response surface methodology (rsm) was highlighted to investigate the effects of biodiesel-diesel blends (b0, b20, b50 and b100), engine operating parameters (engine load and  speed) on co2 emission of a diesel engine. the experiments were conducte...

Depleted natural gas reservoirs are a promising target for Carbon Sequestration with Enhanced Gas Recovery (CSEGR). The focus of this study is on evaluating the importance of Joule-Thomson cooling during CO2 injection into depleted natural gas reservoirs. Joule-Thomson cooling is the adiabatic cooling that accompanies the expansion of a real gas. If Joule-Thomson cooling were extreme, injectivi...

It has been reported that injection of somatostatin into the brain-stem will lead to apnoea in animals. The aim of this study was to determine whether peripheral administration of octreotide, an analogue of somatostatin, could influence the control of breathing. We measured the tidal volume, respiratory rate and ventilatory response to CO2, before and after the intravenous injection of two dose...
