recovery factor is an important parameter in determining commercial viability of the oil reservoirs. wettability is a major factor that affects oil recovery. therefore, changing rock wettability may enhance oil recovery. in this paper, the effect of polysilicon nanoparticles on wettability change of iranian carbonate reservoir is investigated. to assess this, hydrophilic changes of carbonate ro...

Quantitative producibility and textural analysis for carbonate reservoirs ft 1 0 ft3/ft3

A large quantity of world’s oil reserves exists in carbonate reservoirs. Carbonate reservoirs are very sensitive to chemical enhanced oil recovery process because of containing large amount of calcite, dolomite and calcium sulfate minerals. These minerals cause major obstacles during alkali-surfactant-polymer (ASP) flooding. Alkali reacts with these minerals and form undesired precipitations wh...

Wettability alteration is an important method for increasing oil recovery from oil-wet carbonate reservoirs. Chemical agents like surfactants are known as wettability modifiers in carbonate systems. Oil can be recovered from initially oil-wet carbonate reservoirs by wettability alteration from oil-wet to water-wet condition with adding dilute surfactant and electrolyte solutions. This paper inv...

Abstract Cementation exponent or factor is one of most crucial factors in the Archie’s equations that should be estimated precisely order to accurately determine relevant petrophysical characteristics reservoir. Inaccurate estimation this leads incorrect analysis and inaccurate determination water saturation which highly important for economic forecasting hydrocarbon reservoirs. An alternative ...
