Experimental Studies on Strontium Sulfate Formation for Reservoir Injection Systems using Mixture of Seawater / Produced water in one of Carbonate Reservoirs and its Conformance the Jacques Model

In off-shore fields, whenever a mixture of sea water and produced water is used for reservoir pressure maintenance and, or recovery factor improvement, necessary precaution should be considered for the control of mineral scale formation. Incompatibility between sea water and produced water causes serious problems; such as, formation damage as well as flow restriction in producing wellbore and pipelines. In this project, experimental studies have been carried out as to investigate strontium sulfate scale due to the mixtures sea water and produced water under the temperature reservoir. Results have been shown when the ratio of produced water to sea water is increased, strontium sulfate formation intensifies. With the mixture of %60 sea water and %40 produced water, scale Formation is Maximum. Furthermore, experimental results have had reasonable match with the Jacques model.
