Abstract
A method for evaluating an earth formation from a well bore, that includes: collecting at least one of geochemical data, petrophysical data and geomechanical data from a wellbore; and identifying depositional facies of the earth surrounding the wellbore. A computer program product and a system are provided.
Claims23
A method for evaluating an earth formation from a wellbore, the method comprising:
- collecting, by a logging sonde in the wellbore, at least one of geochemical data, petrophysical data and geomechanical data from the wellbore;
- identifying, by a processor, depositional facies of the earth surrounding the wellbore, wherein identifying the depositional facies comprises estimating a weight fraction of one or more of apatite, carbonate, pyrite and uranium in the depositional facies;
- and
- determining, by the processor, a zone of optimal fracture initiation based on the estimating the weight fraction of one or more of apatite, carbonate, pyrite and uranium in the identified depositional facies.

- and
- classifying, by the processor, a zone in the wellbore as one of a perforation zone and a zone of fracture energy attenuation according to the estimating at least the weight fraction of the one or more of apatite, carbonate, pyrite and uranium.
