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.
Claims20
A method for evaluating an earth formation from a wellbore, the method comprising:
- 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 comprising machine readable instructions stored on machine readable media, the instructions for classifying a property of a zone in a wellbore traversing a facies of shale, the product implementing a method comprising:
- receiving input data comprising at least one of geochemical data, petrophysical data and geomechanical data;
- estimating at least one weight fraction of a mineral present in the input data;
- and
- classifying the zone in the wellbore as one of a perforation zone and a zone of fracture energy attenuation according to the estimating.
A system for evaluating properties of an earth formation, the system comprising:
- an input for receiving input data comprising at least one of geochemical data, petrophysical data and geomechanical data descriptive of earth surrounding a wellbore;
- a processor for processing the input data and estimating at least one of a weight fraction and a concentration for at least one mineral in the earth;
- and
- an algorithm for classifying properties of the earth formation according to at least one of the weight fraction and the concentration.
