Abstract
A method of estimating one or more properties of an earth formation includes acquiring formation fluid data indicative of a qualitative property of a formation fluid in a near-field region of an earth formation surrounding a borehole, the near field region including a surface of the borehole, and acquiring acoustic data based on acoustic signals transmitted into a far-field region of the formation, and estimating a property of one or more fractures in the far-field region based on the acoustic data. The method also includes combining the formation fluid data and the acoustic data, and estimating, by a processing device, at least one fracture characteristic of the formation in the near-field region and the far-field region based on the combined data.
