In this paper we develop a new mathematical formulation for chemical compositional reservoir simulation, and provide a comparison of its results on alkaline-surfactant-polymer flooding with those of UTCHEM simulator. Our research has found that the existing chemical compositional model estimates the adsorption effect on the transport of a component reasonably well but it does not satisfy the pr...

Oleic acid induced pulmonary edema was subjected as an experimental model of ARDS. Three adult mongrel dogs were injected with 0. 09 ml/kg of oleic acid into the pulmonary artery and sacrificed 2 hours later. Light and electron microscopic studies were carried out on the pulmonary specimen. The light microsc9pic findings showed bronchovascular cuffs and alveolar flooding. The electron microscop...

In enhanced oil recovery (EOR), the micro-oil droplet heavily affected the stability of foam and prevented foam flooding. In this paper, the oil bridge-stretching mechanism of foam rupture was described through molecular dynamics with the aim of providing supplements to the experiments at the molecular level. Two important phenomena for foam rupture have been pointed out by the simulation. One ...

Despite the increasing interest in CO2 foam flooding for enhanced oil recovery applications, it is challenging to have a successful field operation as the performance of the surfactant is often affected by the presence of crude oil and salinity of the water. It is also challenging to dispose of huge amounts of water associated with the field operation. Due to the incompatibility of the produced...

This contribution introduces a new hybrid enhanced oil recovery (EOR) method which combines smart water-assisted foam (SWAF) flooding, known as the SWAF process. The concept of applying flooding in carbonate reservoirs is novel approach previously unexplored literature. synergy effect technique has potential to mitigate number limitations related individual (i.e., conventional water injection a...
