Abstract
Methods and systems for optimizing drilling operations in a wellbore using a drill string are provided. The methods and systems include measuring a first formation characteristic with at least one sensor, measuring a second formation characteristic by means of a hydraulic test, the at least one second formation characteristic being different from the at least one first formation characteristic, generating a model to represent a formation around the wellbore, the model incorporating the first formation characteristic and the second formation characteristic, and performing a drilling operation based on the generated model.
Claims19
A method for optimizing a drilling operation in a wellbore using a drill string, the method comprising:
- measuring at least one first formation characteristic with at least one sensor;
- measuring at least one second formation characteristic by means of a hydraulic test, the hydraulic test is at least one of producing fluid from and injecting fluid into the wellbore, the at least one second formation characteristic being different from the at least one first formation characteristic;
- generating a model to represent a formation around the wellbore, the model initially based on the at least one first formation characteristic and subsequently and automatically updated based on the at least one second formation characteristic;
- and
- performing a drilling operation based on the generated and updated model.
A system for optimizing a drilling operation in a wellbore using a drill string, the system comprising:
- a carrier configured to be conveyed through the wellbore and carry a drill bit thereon;
- at least one sensor configured to obtain information related to at least one first formation characteristic;
- a hydraulic testing tool configured to obtain information related to at least one second formation characteristic by means of a hydraulic test, wherein the hydraulic testing tool is a pressure pump to at least one of inject and produce fluid;
- and
- a processor configured to optimize a drilling operation, the system configured to:
- measure the at least one first formation characteristic with the at least one sensor;
- measure the at least one second formation characteristic by means of the hydraulic test, the at least one second formation characteristic being different from the at least one first formation characteristic;
- generate a model to represent a formation around the wellbore, the model initially based on the at least one first formation characteristic and subsequently and automatically updated based on the at least one second formation characteristic;
- and
- perform a drilling operation with the drill bit based on the generated and updated model.
