Abstract

"UM MéTODO PARA COMPLETAR UM INTERVALO NãO CONSOLIDADO NUMA FORMAçãO SUBTERRáNEA, E MéTODO DE COMPLETAçãO DOS INTERVALOS NãO CONSOLIDADOS NUMA FORMAçãO SUBTERRáNEA". Um método de completação de um intervalo não consolidado numa formação subterrânea, incluse uma etapa de consolidação. A etapa de consolidação é executada por injeção de uma solução aquosa de partículas coloidais com um modificador pH e/ ou modificador de dureza iónica. Um gel duro forma-se e mantem as partículas juntas. A consolidação segue-se por fraturação hidráulica. O desvio em direção das regiões de permeabilidade baixa pode ser incrementado através da utilização de partículas micrométricas.
