En este punto, el RAOHE se consolidó como una herramienta para la explotación sustentable de los recursos hidrocarburíferos, y un garante de la estabilidad jurídica de una inversión extranjera que reactivase el sector petrolero. Sin embargo, 20 años después, con nuevos avances tecnológicos y garantías ambientales más restrictivas, se ha generado un desfase entre aquello que se encuentra regulado y la actual tecnología empleada en las operaciones de la industria. En este documento, se analizó esta discontinuidad normativa y de procesos desde el enfoque de la tecnología relacionada con el manejo y disposición de agua. Específicamente, en la revisión y análisis de límites permisibles en el manejo de descargas líquidas, reinyección de recortes y fracturamiento hidráulico. Este ensayo se apoyó en el estudio de fuentes de investigación primaria para la definición de sugerencias generales sobre la aplicación y gestión ante la entidad de gestión ambiental, a la espera de que esta información pueda aportar a la articulación de marcos técnicos más comprensibles.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract: The Oil &amp; Gas environmental legislation in Ecuador has had a brief history. Its current regulation body is the RAOHE (Substitute Regulation to the Environmental Regulation for Hydrocarbon Operations in Ecuador) from 2001. At that time, the RAOHE was a robust mechanism that could guarantee the sustainable exploitation of hydrocarbon resources, while providing a solid ground for foreign capitals aiming to invest in the oil sector. Nonetheless, the RAOHE cannot be considered fit anymore to new technological advances and current international environmental regulations standards. Two decades without any update has generated a knowledge gap inside the RAOHE about what is regulated and what could be regulated under best management practices available in the industry. This paper aims to address this operational regulatory gap by performing an extensive literature review focused on wastewater management and better management practices. Specifically, this study evaluates the permissible limits in the handling and treatment of liquid discharges, cuttings reinjection and hydraulic fracturing. This paper provides a set of general suggestions and findings on the aforementioned areas. It is expected that this information can become a tool for policymakers to articulate more comprehensive technical regulatory frameworks.]]></p></abstract>
