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 addresses to a method of removing scale from the DHSV of the oil production string aiming at maintaining the production of the wells and thus avoiding the loss of production. First, a neutralizing solution is placed in the service line, before pumping the scale removing solution through the string to act on the DHSV. Next, the acid is pumped into the production string to react with the calcium carbonate scale. After the time for the dissolution of the scale inside the DHSV, the well is opened for production by the service line. The spent acid is mixed with the neutralizing solution inside the service line, reducing its corrosiveness in relation to the service line, contributing to its preservation.

Abstract: The invention is related to a joint application process of two treatments, scale removal and inhibitor squeeze injection. Through the simultaneous positioning inside the reservoir, it can be applied in scale removal operations for carbonate formations, such as the pre-salt case. Accordingly, there is a way to improve the efficiency of reservoir management, through an innovation in the scaling management process.

Abstract: The present invention addresses to an adaptation of a laser system in a reactor for the application of laser radiation, promoting the thermal catalysis of the complexation reactions of barium sulfate (BaSO4), strontium sulfate (SrSO4) and CaCO3 with application in fields of drilling and completion of wells, as well as lifting and draining systems; in this case, aiming at the removal of scale at an appropriate temperature for the complexation and consequent dissolution of the scale salt in subsea equipment of the production systems.

Abstract: The present invention addresses to a remote divergence method for inhibiting or removing scaling in wells equipped with intelligent completion (IC), including sealing failures, in which a mixture of viscous gel and solid material in different granulometries is used (7) and spheres soluble in water (8) and in oil (6), aiming at maintaining the production of wells equipped with intelligent completion, as well as reducing costs in relation to operations commonly performed with rigs.

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.

Abstract: During meeting for planning operations for scale removal and scale inhibitor squeeze treatment in wells, the possibility of the manifold being partially incrusted with scale raised considering the more critical mixture of water produced. The proposed solution is a method of treatment for removing scale from a manifold. Said method uses the geothermal heating of the exploration reservoir to heat a chemical removal solution (50). Heating is required to ensure the temperature is in a range that is also suitable for conducting the removal reaction, since the distance that the solution travels to the manifold (20) e the low temperature of the underwater environment make the reaction occur inefficiently, as in the case of pre-salt.

Abstract: The present invention relates to a method of applying incrustation inhibitor in completion fluids inside a reservoir in order to ensure the flow of well production. The present invention can be applied in throughout the well area, being directed to the reservoir areas for the management of incrustation and in the elevation and outflow areas, it will work to ensure the flow of production from the wells. It may also be applied as part of the technology used in the construction of wells in the completion phase in the operations to combat loss of circulation as part of the technology used in the completion fluids, it merely being necessary to plan for the addition of the inhibitor chemical product in the manufacture of the completion fluid.
