The flocculation and deposition of asphaltenes causes large losses to the oil industry. Understanding the phase behavior of asphaltenes under conditions closer to those found in reservoirs is important. Therefore, LMCP/UFRJ started operating a high-pressure high-temperature (HPHT) unit coupled to a near-infrared spectrometer probe that can use different flocculants. This work describes the development of a procedure as well as the validation of the results obtained from this unit. Due to the complex composition of crude oil, model systems (MS) were prepared with asphaltenes extracted with n-pentane (C5I) and n-heptane (C7I). The experiments were carried out at atmospheric pressure, titrated with n-heptane, and at 100 and 300 bar titrated with propane. As expected, C7I asphaltenes were more unstable, presenting lower precipitation onset than C5I asphaltenes under ambient conditions and higher pressures. However, for both MS, the stability increased with rising pressure when using propane as a solvent. The proposed method to evaluate asphaltenes precipitation onset was effective for MS in toluene and dead crude oil, and is a promising alternative for investigation of different types of crude oil.","PeriodicalId":41949,"journal":{"name":"Fuentes el Reventon Energetico","volume":"2012 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135719032","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}

Al finalizar la investigación se determinó que la implementación de energía solar fotovoltaica en sectores de difícil acceso y/o desprovistos de servicio eléctrico financieramente no es viable en sectores rurales e incluso urbanos, ya que la vida útil de los paneles solares oscila entre los 10 a 25 años y la recuperación de inversión se proyecta a largo plazo (10 años), implicando con ello elevados costos y un elevado riesgo para inversionistas y el estado; por otro lado, las condiciones geofísicas de la región amazónica del Ecuador es idónea para su implantación; sin embargo, la falta de políticas públicas e incentivos que impulsen el cambio de matriz energética y consecuentemente la implementación de este y otros sistemas de energía renovable no ha sido efectivo.

B49 is an oil field with the typical problems of a mature field, management aimed at increasing the recovery factor and the implementation of an energy efficiency model were the axes to reduce OPEX and achieve a barrel with a production cost of 5.20 USD. The main objective of waterflooding in the field is to maximize oil recovery. Formation water from the north and south zones of B49 is used in waterflooding which increased the recovery factor from 21% to 26%. In Ecuador, the associated gas is not fully exploited. For this reason, its flaring is an accepted practice; however, since 2009 the Ecuadorian State Oil Company has been implementing an ambitious Energy Efficiency program called Optimization of Electricity Generation and Energy Efficiency (OGE&EE for its acronym in Spanish), which is a comprehensive development of generation, distribution and transmission of electricity, as well as the development of facilities for the collection and transportation of associated gas. OGE&EE consists of a group of projects, covering an area of 25,000 km2, 17 oil blocks, 56 oil fields and more than 66 facilities, to date the program results are: • Installation of multiple generation plants with a combined capacity of 325MW, 95MW and can use associated gas as fuel. • 200 km of electric energy transmission and distribution facilities. • Installation of 17 km of gas pipelines out of a total of 100 km, upgrading of existing facilities by implementing waste heat recovery. • The OGE&EE Program has also interconnected the oil industry’s power grid to the national grid, which helps optimize national renewable energy (hydropower). In 2015 the Ecuadorian oil company joined the World Bank initiative “Zero Routine Flaring by 2030”, the Government of Ecuador also joined this initiative in 2018, and as part of PAM EP’s Energy Efficiency program since 2015 it has been working to develop projects and financial solutions to increase power generation with associated gas and decrease gas flaring facilities (flare gas). The production of 12 wells is used for electricity generation, the daily energy demand is an average of 3MW (72 MWh per day). B49’s electricity generation meets the efficiency objectives by using gas in high efficiency generators to cover 100% of the energy needs; the field uses 194 MMcf of gas per year, stops emitting 20 MTon CO2 eq/KWH and saves 420 M USD/year for unconsumed diesel. Problems such as pressure depletion in producing sands, water injection, BSW increase, gas availability, gas flaring limitation, pressure maintenance facilities and gas distribution are issues addressed in this research.","PeriodicalId":41949,"journal":{"name":"Fuentes el Reventon Energetico","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136283699","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}

Los avances científicos han llevado al desarrollo de diversas técnicas de remediación, incluida la fitorremediación y la aplicación de biocarbón. Este estudio involucró la recolección de muestras de suelo no contaminadas de las afueras del municipio de El Rodeo (México), la introducción de petróleo crudo y el tratamiento con la siembra de calabaza (Cucurbita pepo) o la aplicación de biocarbón. Luego de cuatro meses de tratamiento, se analizaron las características del suelo, incluyendo pH (7.50; 5.10), conductividad eléctrica (1.50 dSm-1; 0.20 dSm-1) y contenido de minerales: hierro (0.39 ppm; 0.59 ppm), nitrógeno (1.70 ppm; 1343 ppm), fósforo (0.35 ppm; 297 ppm), potasio (1.70 ppm; 1944 ppm), zinc (0.00 ppm; 23 ppm), calcio (0.00 ppm; 0.00 ppm) y plomo (36 ppm; 10 ppm). Si bien las técnicas utilizadas en el estudio no produjeron suelo fértil, redujeron efectivamente los niveles de hidrocarburos totales de petróleo (TPH) y permiten ser implementadas a escala industrial para reducir las concentraciones de hidrocarburos, mitigando así la toxicidad del ecosistema y mejorando el valor estético de las áreas afectadas.

Supercritical carbon dioxide offers high selectivity at the end of the extraction process of light hydrocarbons from heavy oils mixture. A simulation technique in Aspen Plus ®software was used to develop the process and sensitivity analysis of the extraction configuration. The simulation of extraction process includes two output streams: the first one, a top stream (unpaved oil), and the second one a bottom stream (asphalt residue). A steady state methodology was implemented for process simulation. The sensitivity analysis was used to assess the influence of variables such as solvent flow rate, temperature and pressure. It was found a significant increase in the flow rate of unpaved oil when the solvent flow rate is increased. Optimal extraction values were selected depending on temperature and pressure effects over the process. An increase in temperature directly enhances the quality of API gravity.
