Demulsifiers are agents added to destabilize these emulsions. The objective of this work is to evaluate the stability of w/o emulsions formed from an oil phase with different polarities (kerosene and toluene) containing asphaltene fractions C3I, C5I, and C7I, and how these systems affect the action of a demulsifier additive. Systems containing asphaltenes in toluene were more stable when using the C7I fraction due to its greater polarity and, consequently, considerable action at the interface. With the oil phase composed of a less polar solvent (kerosene), the C3I fraction increased the stability of the emulsion by reducing the action of the demulsifying additive, with an upper asphaltenes concentration limit of 1.0% observed where the action of the demulsifying agent was affected.","PeriodicalId":9312,"journal":{"name":"Brazilian Journal of Petroleum and Gas","volume":"24 38","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141685290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The model geometry has azimuthal symmetry, which simplifies the forward modeling and the inversion procedure. In the direct problem, the finite element method is used in the numerical solution of the Helmholtz equation. In the inverse problem, the study discusses the use of three stabilizer functionals: Global Smoothness (GS), Total Variation (TV), and Absolute Equality (AE). The first uses a smoothing function in the L2 norm, while the latter uses smoothing in the L1 norm, for it accepts abrupt changes between adjacent parameters. The results show that the TV method generated good estimates of both geometry and conductivity of the bodies, both for small and large conductivity contrast between the targets and the surrounding environment. Through the results, one can also observe that the regularization of the Total Variation presented a better estimate of the parameters than the Global Smoothness. In most of the synthetic models used in this work, the best estimates of the proposed model occurred when Absolute Equality constraints were used on the cells at the edges of the inversion grid, in addition to the stabilizer functional.","PeriodicalId":9312,"journal":{"name":"Brazilian Journal of Petroleum and Gas","volume":"18 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141686025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Standard biocides are used as chemical treatment, but the toxicity and the high volumes can cause elevated environmental impacts. Treatment effectiveness and, consequently, reduction of environmental impact may be improved through an adequate planning. The present study examines the bacterial resistance mechanisms to biocides and suggests a 5-step approach for the treatment planning: 1) determination of objectives; 2) bioaudit; 3) selection of biocide(s) in laboratory; 4) selection of representative Key Performance Indicators (KPI); and 5) monitoring of the treatment. Finally, this article demonstrates an optimization of a biocide treatment using the 5-step approach. The results show a reduction of approximately 50% in the dosage of the biocide, as well as reduction in frequency of dosage.","PeriodicalId":9312,"journal":{"name":"Brazilian Journal of Petroleum and Gas","volume":"52 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138952438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The front of the drag force is caused by the flow of fluids inside the pores of the rock-reservoir. Therefore, reservoir parameters must be analyzed to observe how they behave considering the production of solids. The operational parameters used in this study were compressional wave, shear wave and gamma ray profiles, depth, average overburden density, reservoir fluid pressure, and bottom pressure in flow during production. These data allowed us to predict the production of sand in a mature oil reservoir. The results show that in the zones that presented solids production, through the control of the dynamic pressure, it is possible to control the production of sand and determine the critical point of its production.","PeriodicalId":9312,"journal":{"name":"Brazilian Journal of Petroleum and Gas","volume":"31 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138950237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This interaction causes reactive phenomena that are not fully understood. Experimental tests on carbonate facies are crucial for understanding reactions and their impact on reservoir characteristics. This study investigates experimentally reactions generated by reactive fluid flow in carbonate rocks from two geological scenarios by analyzing chemical and morphological parameters before and after the tests. Salinity was the most significant parameter for reactive flow, impacting porosity for modern continental carbonate samples from Patagonia. However, the sample from the Brazilian pre-salt showed higher mineral stability and less mineral dissolution. Results provide data for simulating reactive transport in these rocks for CCS and understanding diagenetic processes' impact on reservoir quality.","PeriodicalId":9312,"journal":{"name":"Brazilian Journal of Petroleum and Gas","volume":"38 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138949915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Asphaltenes may precipitate and eventually deposit on the rock surface in CO2 WAG injection, reducing permeability and porosity and thus affecting oil production. This work aims to determine under which operating conditions the highest recovery factor (RF) is reached in a WAG injection process and analyze the behavior of the physical properties of oil and rock, in addition to precipitation and deposition of asphaltenes. The results show that the higher the WAG ratio is, the higher the pressures achieved will be, reducing the amount of precipitated asphaltenes and its deposition. However, as the WAG ratio increases, the water breakthrough occurs earlier, causing the macroscopic displacement efficiency to decrease, impairing oil production. Furthermore, in most cases, higher RFs are reached for intermediate WAG ratios in a given injection cycle.","PeriodicalId":9312,"journal":{"name":"Brazilian Journal of Petroleum and Gas","volume":"4 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138952012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
