Avaliação do potencial uso de bioglicerina como base para formulação de fluidos de perfuração aquosos para poços de petróleo e gás

Abstract: WELLS. The growing global concern about the environment associated with academic and government efforts are enabling a number of alternatives for sustainable development. Within this perspective one can include the search for value-added products using waste from renewable energy sources, such as those from the production of biodiesel. The rapid development of biodiesel production in Brazil directly affected the supply of glycerin and therefore the sector is seeking a market that can absorb this waste. Thus, w… Show more

“…Therefore, the occurrence of disintegration in the presence of glycerin, although in a low proportion, may be associated with the intermolecular interaction of the clay surface with glycerol, which is the main component of this compound, since its hydrophilicity ensures the chemical affinity between them [26]. However, this chemical affinity does not constitute a possibility for the occurrence of premature swelling of the pellets in this medium since glycerin seems to have a limited invasion radius in bentonite specimens [27].…”

“…Assim, novas bases sintéticas vêm sendo propostas para formulação de fluidos cada vez menos agressivos ao meio ambiente e que atendam as aplicações das bases aquosas e oleosas convencionais. Como exemplo, têm-se os fluidos de perfuração constituídos de glicerina (Corrêa et al, 2017;Cruz et al, 2015), óleos vegetais (Silva, 2003) e microemulsão contendo glicerina e óleo vegetal (Curbelo et al, 2016).…”

“…Contudo, apesar dos fluidos de perfuração de base sintética hoje serem mais biodegradáveis e menos tóxicos, é necessário ficar atento às restrições impostas pelos órgãos ambientais com relação ao seu descarte, assim como dos cascalhos gerados durante a perfuração offshore que entraram em contato com os fluidos (CORRÊA et al, 2017). Nesse contexto, o Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis (IBAMA) estabeleceu, através da Instrução Normativa N° 01/2018 (IBAMA, 2018), diretrizes para regulamentar as condições ambientais de uso e descarte de resíduos provenientes da perfuração marítima de petróleo.…”
