Abstract

"MéTODO E APARELHO PARA ESTIMULAR UMA FORMAçãO FURO ABAIXO". Um método para estimular uma formação furo abaixo de acordo com o qual uma pluralidade de bocais de jato é localizada em uma relação espaçada com a parede da formação para formar um anel entre os bocais e a formação. Um fluido de estimulação que contém um ácido é bombeado a uma pressão predeterminada através dos bocais para o interior do anel e contra a parede da formação. Um gás é bombeado para o interior do anel, de modo que o fluido de estimulação se mistura com o gás para gerar espuma antes que a mistura seja jateada no sentido da formação para impactar a parede da formação. é enfatizado que este resumo é fornecido para estar de acordo com as regras que requerem um resumo que irá permitir a um pesquisador, ou outro leitor, alcançar rapidamente o assunto da divulgação técnica, e é submetido com o entendimento que ele não será utilizado para interpretar ou limitar o escopo ou significado das reivindicações sob a 37CFR 1.72.
