NOISE ESTIMATION IN A VECTOR SENSING STREAMER
First Claim
1. A method, comprising:
- recording a first set of data using a first type of sensor;
recording a second set of data using a second type of sensor, the first and second sets of data being contemporaneously acquired by co-located sensors; and
removing noise from the first data set using the second data set.

Abstract
A method includes recording a first set of data using a first type of sensor; recording a second set of data using a second type of sensor, the first and second sets of data being contemporaneously acquired by co-located sensors; and removing noise from the first data set using the second data set. An apparatus includes a survey vessel towing an array of towed streamers including a plurality of paired, co-located sensors densely distributed along the streamers. A first one of each sensor pair is of a first type and a second one of each sensor pair is of a second type. A computing apparatus records a first set of data acquire by the first type of sensor and a second data set acquire by the second type of sensor. The computing apparatus then removes noise from the first data set using the second data set.
