... and observations of contact angles were conducted to validate possible wettability changes. Results from multiphase permeability flow tests show an irreversible reduction in endpoint brine permeability and relative permeability with increasing concentration of friction reducer. Our results also show that effective...

... model followed by a mineral scale prediction software to investigate the specific switching strategy for a field that has multiple wells and significantly more complex heterogeneity. The results show that barium concentrations in the formation brine affect the choice of switching time more than...

...‐injection was performed at 2.45 million std m 3 of cumulative oil. See the text for further explanation. Xanthan biopolymer is a polysaccharide produced by the bacteria Xanthomonas campestries. The molecular weight is reported to be on the order of several MDa. The polymer is soluble in brine...

... interactions between the injected brine and the formation brine, rock and oil. Very little work has appeared in the literature on how cEOR processes can influence the severity of the mineral scaling problem that occurs in the field and how this can be managed. This study investigates barium and sulfate...

... for monitoring interwell connectivity and predicting and managing oilfield scale resulting from brine supersaturation. Coupling thermodynamic calculations with produced‐water analysis helps to identify geochemical effects that could affect oil recovery. This work addresses the difference that reservoir...

... that the shale samples were preserved because large changes in shale mechanical properties caused by sample desiccation have been observed. The fracture conductivities of unpropped fractures created in each of the shale samples were measured as a function of closure stress by using nitrogen or brine...

... of initial pH values and in two brine systems. The effect of pH was examined further by changing the salt from Na 2 S·9H 2 O to NaSH· x H 2 O, therefore changing the initial sulfide source from S 2– to HS – , as part of an ongoing method-development strategy. The formation of ZnS was achieved...

Specifically, the precipitated complex was isolated and its solubility was determined experimentally in various brine compositions and as a function of temperature. MWDs were determined for the various fractions of PPCA. The solubility of the precipitated PPCA_Ca...

The first stage of this study involved identifying the split between connate water, aquifer water, and seawater in the produced brine. This provided data that could be used to calculate the evolution of the scaling risk over...
