Abstract
Aspects of the subject technology relate to systems, methods, and computer-readable media for synthesizing sonic logs for downhole environments. Data associated with a wellbore in a formation is accessed. A model configured to identify one or more characteristics associated with sound traveling through one or more formation is accessed. The data is applied to the model to predict a characteristics of the formation that is identifiable through sonic logging.
Claims20
A method comprising:
- accessing data associated with a wellbore in a formation;
- accessing a model configured to identify one or more characteristics associated with sound traveling through one or more formations;
- applying the data to the model to predict a characteristic of the formation that is identifiable through sonic logging;
- synthesizing sonic logs based on the predicted characteristic of the formation by substituting the predicted characteristic of the formation for the data missing from the sonic logs;
- selecting a type of drill bit for drilling the wellbore through the formation based on the predicted characteristic and the synthesized sonic logs;
- and
- controlling a speed of the drill bit while drilling the wellbore through the formation based on the predicted characteristic and the synthesized sonic logs.
A system comprising:
- one or more processors;
- and
- at least one computer-readable storage medium having stored therein instructions which, when executed by the one or more processors, cause the one or more processors to:
- access data associated with a wellbore in a formation;
- access a model configured to identify one or more characteristics associated with sound traveling through one or more formations;
- apply the data to the model to predict a characteristic of the formation that is identifiable through sonic logging;
- synthesizing sonic logs based on the predicted characteristic of the formation by substituting the predicted characteristic of the formation for the data missing from the sonic logs;
- select a type of drill bit for drilling the wellbore through the formation based on the predicted characteristic and the synthesized sonic logs;
- and
- control a speed of the drill bit while drilling the wellbore through the formation based on the predicted characteristic and the synthesized sonic logs.
A non-transitory computer-readable storage medium having stored therein instructions which, when executed by one or more processors, cause the one or more processors to:
- access data associated with a wellbore in a formation;
- access a model configured to identify one or more characteristics associated with sound traveling through one or more formations;
- apply the data to the model to predict a characteristic of the formation that is identifiable through sonic logging;
- synthesizing sonic logs based on the predicted characteristic of the formation by substituting the predicted characteristic of the formation for the data missing from the sonic logs;
- select a type of drill bit for drilling the wellbore through the formation based on the predicted characteristic and the synthesized sonic logs;
- and
- control a speed of the drill bit while drilling the wellbore through the formation based on the predicted characteristic and the synthesized sonic logs.
