Abstract

métodos de exploração sísmica. este é um método para separar fontes simultâneas que usa uma abordagem do tipo inversão. cada fonte será de preferência ativada num tempo aleatório com respeito às outras. estas demoras aleatórias tendem a tornar a interferência entre fontes incoerente, enquanto as reflexões criam eventos coerentes dentro de uma série de tiros. a separação dos tiros é realizada via um processo de inversão numérica que utiliza as varreduras para cada tiro, os tempos de início de cada tiro e a coercência de eventos de reflexão entre tiros próximos. este método permitirá que sondagens sísmicas sejam adquiridas mais rapida e mais economicamente.
