Abstract: The present invention addresses to a remote and autonomous chemical treatment system for application in producing wells of offshore platforms aiming at treatments for removal and prevention of production string fouling, selective completion system, well safety equipment (DHSV, HFIV) and rock formation. The purpose of this invention is to completely replace the stimulation boat, thus allowing treatments to be carried out with resources from the routine operational contracting of the offshore production unit.

Abstract: The present invention addresses to a real-time flow assurance occurrence monitoring system with the aim of reducing oil production losses caused by occurrences in the flow assurance area, which uses a web tool to integrate results of simulations of multiphase flow and thermodynamic simulators with production data and specific correlations, developed to monitor the formation of deposits or blockages in subsea lines. This tool has the specific objective of monitoring the formation of hydrates, paraffins and emulsions in real time and other occurrences that may cause a production shutdown. Based on this information, it issues an alert of the occurrence in the control rooms of the operational units, supporting decision-making on operational procedures that must be carried out to avoid the loss of oil production. It further records the operations carried out to mitigate occurrences. All data is structured in tables and graphs and can be exported to other systems.

Abstract: The present invention refers to a method of evaluating the rheological properties of water-in-oil emulsions (W/O) in which it presents a new paradigm in the exploration and production segments generated using artificial intelligence in the analysis of rheological data of fluids produced in the Brazilian oil fields. The developed model makes it possible to predict the rheological properties of emulsions throughout the production life cycle of an oil field. The expected gains are associated with the use of correlations representative of the flow behavior of Brazilian oils, with the acceleration of the prioritization process of candidate wells for the demulsifier subsea (DSS) injection of chemical products and, consequently, with the increase in the production of oil and gas with subsequent value generation.

Abstract: The present invention refers to automated method for the selection of oil producing wells that are candidates for subsea demulsifier injection, with application in mature fields after the start of water production, aiming at increasing oil and gas production and reducing the instability of the wells.
