7 Persistent scatterers synthetic aperture radar interferometry (PSI) analysis is viewed as a 8 promising monitoring technique for multiyear detection of ground surface displacements 9 during long term CO2 injection into deep aquifers (of the order of 25 to 50 years). 10 This technique was successfully utilized at the CO2 storage site of In-Salah (Algeria). 11 Nevertheless, this success may not...

Direct injection of liquid CO2 into the ocean has been proposed as one method to reduce the emission levels of CO2 into the atmosphere. When liquid CO2 is injected (normally as droplets) at ocean depths >500 m, a solid interfacial region between the CO2 and the water is observed to form. This region consists of hydrate clathrates and hinders the rate of dissolution of CO2. It is, therefore, exp...

climate change is one of the major global concerns. emission of anthropogenic greenhouse gases is the main cause of climate change. one way of reducing the emissions is the application of carbon capture and storage (ccs) in geological formations. in this study, feasibility of ccs was studied in an iranian gas production area located in the northern persian gulf coast in the south of country. th...

CO2 flooding process as a common enhanced oil recovery method may suffer from interface instability due to fingering and gravity override, therefore, in this study a method to improve the performance of CO2 flooding through an integrated ultraosund-CO2 flooding process is presented. Ultrasonic waves can deliver energy from a generator to oil and affect its properties such as internal energy and...

the main purpose of this investigation is to study the effect of near miscible co2 injection in different porous mediums on both lab and field scales. this effect can be traced by the change of two-phase gas-oil relative permeability curves. in this work, the experiments have been performed on three rock types (i.e. sandstone, dolomite, and artificial fractured sandstone) based on an incrementa...

PURPOSE The purpose of this study was to assess the accuracy of carbon dioxide compared to iodinated contrast material for determining inferior vena cava (IVC) diameter prior to filter placement, and to assess the safety of CO2 when used for this purpose. PATIENTS AND METHODS Consecutive patients undergoing inferior vena cavography prior to filter placement were prospectively evaluated with u...

Trautz, Tommy Phelps, and Thomas M. Daley ABSTRACT The Frio Brine pilot is a closely monitored, small-volume (1,600 tons), short-duration experiment using injection of CO2 into a high-permeability brine-bearing sandsto...

Although CO2 injection is one of the most common methods in enhanced oil recovery, it could alter fluid properties of oil and cause some problems such as asphaltene precipitation. The maximum amount of asphaltene precipitation occurs near the fluid pressure and concentration saturation. According to the description of asphaltene deposition onset, the bubble point pressure has a very special imp...

Carbon dioxide has been used commercially to recover oil from reservoirs for more than 40 years. Currently, CO2 flooding is the second most applied enhanced oil recovery (EOR) process in the world behind steam flooding. Water alternating gas (WAG) injection has been a popular method to control mobility and improve volumetric sweep efficiency for CO2 flooding. Average EOR is about 9.7% with a ra...
