Well bore fracture analysis
Electrical and acoustic image logs have been collected from well 58A-10 in crystalline rock on the eastern margin. Electrical image logs appear to be sensitive to variations in mineralogy, porosity, and fluid content that highlight both natural fractures and rock fabrics. These fabric elements account for about 50% of the total population of planar structures seen in the electrical image log, but locally approach 100%. Acoustic image logs reveal a similar natural fracture population, but generally image slightly fewer fractures, and do not reveal rock fabric. Both logs also record textural properties of deformed materials within fractures..
