Abstract
A method of determining the quality of seismic data comprises the steps of defining a predetermined threshold (step 12) from a characteristic of a first set of seismic data and translating the difference between the predetermined threshold and the corresponding characteristic of a second set of seismic data into a measure of quality of the second set of seismic data (step S16).
Claims22
A method of determining a quality of a second set of seismic data from a first set of existing seismic data, comprising the steps of:
- (a) retrieving said first set of existing seismic data;
- (b) determining, from said first set of existing seismic data, a minimum acceptable threshold associated with a characteristic of said first set of existing seismic data;
- (c) acquiring said second set of seismic data, said second set of seismic data having one or more corresponding characteristics, whereby said one or more corresponding characteristics of said second set of seismic data must remain above said threshold in order to determine that said second set of seismic data is of acceptable quality in accordance with a set of defined objectives;
- (d) comparing said one or more corresponding characteristics of said second set of seismic data with said threshold;
- (e) determining that said second set of seismic data is of acceptable quality when said one or more corresponding characteristics of said second set of seismic data is equal to or greater than said threshold;
- and
- (f) determining that said second set of seismic data is not of acceptable quality when said one or more corresponding characteristics of said second set of seismic data is not equal to or greater than said threshold.
An apparatus for determining a quality of a second set of seismic data from a first set of existing seismic data, comprising:
- first means for retrieving said first set of existing seismic data;
- second means for determining, from said first set of existing seismic data, a minimum acceptable threshold associated with a characteristic of said first set of existing seismic data;
- third means for acquiring said second set of seismic data, said second set of seismic data having one or more corresponding characteristics, whereby said one or more corresponding characteristics of said second set of seismic data must remain above said threshold in order to determine that said second set of seismic data is of acceptable quality in accordance with a set of defined objectives;
- fourth means for comparing said one or more corresponding characteristics of said second set of seismic data with said threshold;
- fifth means for determining that said second set of seismic data is of acceptable quality when said one or more corresponding characteristics of said second set of seismic data is equal to or greater than said threshold;
- and
- said fifth means determining that said second set of seismic data is not of acceptable quality when said one or more corresponding characteristics of said second set of seismic data is not equal to or greater than said threshold.
A method of determining a quality of seismic data, comprising the steps of:
- defining a predetermined threshold associated with a characteristic of a first set of seismic data;
- and
- translating a difference between said predetermined threshold and a corresponding characteristic of a second set of seismic data into a measure of quality associated with said second set of seismic data.
