Abstract

Un método para estimar ruido en registros sísmicos de movimiento de partículas y componentes ascendentes (datos fantasmas eliminados) y descendentes de campos de ondas registrados incluye ingresar la presión relacionada y el movimiento de partículas relacionados con señales sísmicas; se aplica una transformación de promoción de dispersión a las señales sísmicas de entrada; una matriz à y vector columna (ver símbolo) se construyen en la computadora de conformidad con la expresión: (ver Fórmula) en donde d representa un campo de ondas sísmicas descendentes, u representa un campo de ondas sísmicas ascendentes, n representa el ruido y ? representa un escalar elegido por el usuario para ajustar énfasis del ruido; una minimización restringida se resuelve de conformidad con la expresión (ver Fórmula) para (ver símbolo); en donde µ representa un escalar elegido por el usuario para ajustar la importancia relativa de las normas de minimización; la minimización restringida resuelta es transformada inversa y reordenada de regreso en un dominio de las señales sísmicas de entrada; se genera una salida que comprende una estimación del ruido contenido en el registro de movimiento de partículas, el campo de ondas descendente y el campo de ondas ascendente (con datos fantasmas eliminados).
