Abstract
A system includes at least one processing unit and a bottomhole assembly (BHA) that includes or communicates with the at least one processing unit. The BHA includes at least one drilling component and at least one acoustic transducer to convert drilling noise into one or more electrical signals. The at least one processing unit analyzes the one or more electrical signals or related data to categorize different components of the drilling noise as rock contact noise and mechanical noise. The at least one processing unit derives a data log, a plan, or a control signal based on the categorized drilling noise components.
Claims22
A system that comprises:
- at least one processing unit;
- and
- a bottomhole assembly (BHA) that includes or communicates with the at least one processing unit, the BHA comprising:
- at least one drilling component;
- and
- at least one acoustic transducer to convert drilling noise into one or more electrical signals;
- wherein the at least one processing unit analyzes the one or more electrical signals or related data to categorize different components of the drilling noise as rock contact noise and mechanical noise,
- wherein the at least one processing unit derives a data log, a plan, or a control signal based on the categorized drilling noise components to adjust drilling operations and adjust well completion plans.
A method that comprises:
- drilling a borehole;
- recording a drilling noise;
- categorizing different components of the recorded drilling noise as rock contact noise and mechanical noise;
- deriving a data log, a plan, or a control signal based on the categorized drilling noise components;
- and
- adjusting drilling operations and well completion plans using the derived data log, plan, or control signal.
