Sobre IBD

Os agentes tensioativos, ou surfactantes, são amplamente utilizados e encontram um grande número de aplicações na indústria petrolífera. Isso é atribuído à sua notável capacidade de influenciar as propriedades das superfícies e interfaces. Recentemente, uma das aplicações mais importantes dos surfactantes é como inibidores de corrosão eficazes na indústria petrolífera. Um dos principais consumidores de inibidores de corrosão é a indústria petrolífera, onde são empregados para reduzir a taxa de corrosão de diferentes tipos de ligas de aço em equipamentos de poços de gás e petróleo. Tanto a corrosão geral como a localizada são encontradas nesta indústria. Os desemulsificantes são uma classe de surfactantes usados para desestabilizar emulsões. Essa desestabilização é alcançada através da redução da tensão interfacial na interface da emulsão. A corrosão, juntamente com a carga cíclica mecânica, causa fadiga por corrosão, o que resulta em falhas prematuras importantes na coluna de perfuração. É uma causa extrema de preocupação para aqueles que atuam no ramo de perfuração.
