... an increasing cause of oil well stimulation Failure. The objective of the paper is to evaluate the performance of coconut oil as a bio-oil dispersant against commercial dispersants in preventing asphaltene sludge while acidizing carbonate cores with 15 wt.% HCl and a chelating agent. A Kuwaiti crude oil...

... is restored in the lab to mimic the process of drilling fluid mixing with crude oil in horizontal drilling. The stable emulsion is formed by mixing the crude oil with drilling fluid in different proportions. Furthermore, damage level is quantified by well test interpretation. Skin factor, wellbore storage...

... of the gas to achieve miscibility with the crude oil as well as operational limitations such as an absence of transportation pipelines for the CO 2 . Even though miscibility may not be achieved, immiscible CO 2 EOR can effectively increase production and sequester CO 2 resulting in an increase of revenue...

... reduces in high-salinity environments, high-temperature formations (>212°F), and in contact with crude oil. The present study the using of nanoparticles and viscoelastic surfactants (VES) to improve foam mobility control for EOR application. This paper study the CO 2 -foam stability with using alpha...

... in chemical treatments to control this phenomenon. The aim of this paper is to assess the asphaltenes precipitation onset of crude oils in the presence of cardanol, by titrating the crude with n-heptane. Moreover, based on this results obtained at atmosphere pressure, the asphaltenes precipitation onset...

... Abstract Royalty Lease Evaluation (RLE) distillation analysis was performed on six hundred (600) wells in Petrotrin's Soldado acreage. This data has been traditionally generated for use by Petrotrin's refinery to determine if the crude oil feedstock is compatible to the refinery configuration...

... analyses that differ from classical foam assessments. This work presents the coreflood results of a steam-foam process evaluation for the Ratqa Lower Fars (RQLF) heavy oil reservoir in Kuwait. Using specifically designed foaming surfactants, coreflood tests in the absence and presence of heavy crude oil...

... (LSWI) in oil recovery using a crude oil and synthetic formation water of a sandstone reservoir in northeast Brazil. Two Botucatu sandstone core samples of 6 in of length and 2 in of diameter were used for the coreflooding experiments. The fluids used included a light crude oil sample, and synthetic...

... that the original wettability can be restored only if the water-wetted channels in a rock are soaked with asphaltic crude oil under high temperature for a long time period. Therefore, under oil-field operational condition, the wettability of the oil formation will not be restored as much as it has been...
