Abstract: The present invention relates to a machine learning unsupervised method to improve results obtained in electro-facies models. In this method it is possible to subdivide profile data into different unsupervised classes interactively and intuitively based on rock data information, seeking not only to meet the need to respect profile data values, but also to represent the geological knowledge that exists in the labeled data which serves as a guide in decision making to define which classes should be subdivided or attached. In the method, the result is constructed little by little and intuitively, just like the process of analyzing an outcrop or core. Initially, profile data is used to identify the most relevant and easily separable macro characteristics, such as reservoir and non-reservoir rock. Additionally, there is the possibility of interactively subdividing or attaching classes to test scenarios and quickly validate concepts.

Abstract: The present invention relates to a process for converting vegetable oils, animal fats, residual edible oils and carboxylic acids into renewable liquid fuels, such as bionaphtha, bioJET-A1 and renewable diesel, for use in a mixture with fossil fuels. The process consists of two steps: hydrotreating and hydrocracking. The effluent from the hydrotreatment step presents aromatics, olefins and compounds resulting from the polymerization of esters and acids in its composition. This fact occurs due to the use of partially reduced catalysts and without injection of sulfide agent and allows obtaining a bioJET-A1 with adequate quality for use in a mixture with fossil kerosene. At the same time, the process generates, in addition to products in the distillation range of naphtha, kerosene and diesel, high molecular weight linear paraffins (with up to 40 carbon atoms).

Abstract: A control process for microgrids for voltage regulation on the main bus and power factor (PF) regulation at generator terminals is presented, especially in events scheduled in the microgrid that result in electrical transients, such as direct starting of induction motors (IM). The technology takes advantage of idle capacity of distributed converters (for example: frequency inverters, “variable frequency drive” or VFD) of microgrids making them, in coordinated manner, injecting and/or absorbing reactive power, in addition to exploit the reduced latency of autonomous VFD control during the transient. The Power-Based Control (PBC) technique is used and a modified Volt-VAr function is created applied during the transitional regime.
