... the Grantham (1988 ) paper. However, the API gravities in Jawdah field varied ranging from light to moderately heavy oil (20-33 API), indicating a possibility of other geological factors affected the alteration of the crude oil. Therefore, these oils were further characterized by interpreting the level...

... with the crude oil is not very well studied for carbonate reservoirs. This work presents emulsion formation in water-oil systems in the presence of water-insoluble fines. The effect of amount of fines on emulsion formation is also examined. Synthetic seawater (SSW) and deionized water (DIW) were used as water...

... reserves. There are around 160 types of crude oils being produced worldwide and the price differentials between crude oils can be $15 /barrel or higher. Refiners find themselves faced with the difficult question of searching for crude blends to maximize the use of their existing assets or to choose crude...

... media exhibit remarkably stronger foam with mixtures of nano-ash and surfactant, such that the amount of produced liquids from the cores significantly increases. In presence of oil, the nano-ash-AOS foam shows a higher stability, although crude oil tends to form stable emulsions in water in presence...

... drilled from Gildehauser and Bentheimer sandstone outcrop material with diameters of approximately 7.55 cm and lengths of approximately 27 cm and one meter. Crude oil with in-situ viscosities of 1.3, 2.3 and 100 cP was used in the experiments. The changes in the fluid saturation distributions with time...

... Abstract The upstream petroleum industry faces operational and technical challenges due to the production of crude oil containing waxes, asphaltenes and aromatic compounds and also due to the formation of gas hydrates resulting in their deposition in the surface and production equipments...

.... The modulating feature of the mixer allows for a maintained and consistent low differential pressure under varying flow rate conditions. This same mixer technology can also be applied on the crude oil treating pipeline using our ProMix – for chemical injection of de-emulsifiers, corrosion inhibitors, and scale...

... Abstract Assessing heavy oil composition of a green field, with an accepted level of uncertainty so it can be used for refinery capacity planning is a critical challenge. Knowledge of heavy crude oil properties is vital to understand potential adverse impact on process performance and total...
