Metodología para la determinación de puntos de control para derrames de hidrocarburos en el bloque 66-operadora Petrobell, como componente del plan de contingencia ambiental

Abstract

Environmental pollution from the oil spilsl is a latent risk in oil exploitation areas. In Ecuador, depending to a large extent on oil extraction, it is an area highly exposed to this type of vicissitudes. Because of this, it is essential to have a contingency plan that allows mitigating the impact of this risk. After determining that the Tiguino Block, operated by Petrobell Inc. Grantmining. As an area of study, we focus on the 3 main rivers, (Tecuino River, Shiripuno River and Cristalino River) as these are the ones that present the highest risk of oil spills. The method used to evaluate the risks was the Mosler, divided into 4 phases 1° Risk Definition, 2° Risk Analysis, 3° Risk Assessment, 4° Risk Class Calculation. With the information collected, it was possible to determine the areas of study, the channel depth, the section of the rivers, the control points and their accesses through the different available routes. The results obtained with the study carried out indicate that the risk of spillage is high since the flow lines of the operational wells of the Tiguino 2A platform pass over the Tiguino River and the Tiguino Cononaco pipeline passes over the Tiguino River, in addition to the Shiripuno River, there is a social conflict between the community and the operator. Finally, control points were established for a better performance against possible spills into water bodies, thus avoiding large-scale pollution.
