Abstract
A method for adjusting a parameter of a wellbore operation includes: conveying a carrier through the wellbore; performing a resistivity measurement on the formation using a resistivity tool disposed on the carrier; performing an acoustic measurement on the formation using an acoustic tool disposed on the carrier; generating with a at least one processor a map of the formation using the resistivity measurement and the acoustic measurement, and adjusting the parameter using the map.
Claims21
A method for adjusting a physical parameter of a wellbore operation, the method comprising:
- conveying a carrier through a wellbore;
- performing a resistivity measurement on a formation surrounding the wellbore using a resistivity tool disposed on the carrier;
- performing an acoustic measurement on the formation using an acoustic tool disposed on the carrier;
- generating with at least one processor a map of the formation,
- interpreting with the at least one processor one or more geological structures of the formation based on the acoustic measurement and updating the map by using a constrained inversion of the resistivity measurement based on the one or more geological structures of the formation to provide an updated map;
- and
- adjusting the physical parameter of the wellbore operation using the updated map.
An apparatus for adjusting a physical parameter of a wellbore operation, the apparatus comprising:
- a carrier configured to be conveyed through a wellbore;
- a resistivity tool disposed on the carrier and configured to perform a resistivity measurement on a formation surrounding the wellbore;
- an acoustic tool disposed on the carrier and configured to perform an acoustic measurement on the formation;
- at least one processor configured to:
- generate a map of the formation,
- interpret one or more geological structures of the formation based on the acoustic measurement and updating the map by using a constrained inversion of the resistivity measurement based on the one or more geological structures of the formation to provide an updated map;
- and
- adjust the physical parameter of the wellbore operation using the updated map.
