Abstract: The present invention refers to a portable analysis system that, from analytical methodologies set based on digital images acquired by portable devices and accessories developed in an expedited way, allows the performance of the analytical test without technical deepening by the executor of the analysis. Such methodologies allow the evaluation of chemical species relevant to the O&G sector, for following up compositional parameters in aqueous samples and analytical monitoring of production and effluent treatment. Thus, a quick implementation is possible considering eventual diagnoses associated with the parameters of interest and following up of different processes. The application can be in any laboratory present in an operational unit, whether offshore or onshore, as well as it can be used for direct measurement in the field, depending on the necessary environmental and operating conditions.

Abstract: The present invention provides a system and method for use of desulphated injection water from offshore platforms for utilization in inhibition squeeze operations. The system is capable of increasing the treatment capacity by joining the pumping system from the stimulation vessel with the water injection system from the offshore platform. In the initial treatment step, according to the method of this invention, the fluid containing the inhibitor is pumped exclusively by the vessel, followed by an aqueous overflush, where the injection water is mixed with part of the inhibitor cushion pumped by the stimulation vessel.
