... rock-fluid interactions between synthetic brine, crude oil from a Pre-Salt field and rocks and minerals with similar characteristics to the Pre-Salt formations. We studied the effects of aging time on different solid substrates. We found that, even though unaged quartz showed greater interaction...

... Abstract Experimental data confirm that the EOR-effects observed during Smart Water flooding can be explained by wettability alteration toward more water-wet conditions. Detailed knowledge about the important crude oil – brine – rock parameters affecting reservoir wetting, fluid flow...

... reported. This work uses the drop shape analysis technique to measure the IFT between a Pre-Salt crude oil and synthetic brine with the composition of formation water in the presence and absence of CO 2 . The results were compared to those obtained for synthetic oil consisting of alkane and aromatic...

... on asphaltenes stability in the oil matrix. Four different crude oils were used to implement this experiment. In the first step, asphaltenes were precipitated by n-heptane. The asphaltenes were then dissolved in toluene and CO 2 was injected (at 870 psi) to these solutions and they were mixed at 752°F...

Therefore it may be necessary to look at using the produced crude oil itself as the fuel for power generation, and this in itself requires careful consideration by the providers of the different potential power generation technologies. Liquid fuels also produce more NO x when burned, and are more carbon...
