摘要

Fracture permeability is often estimated from well tests. With the help of a case study, the fracture permeability estimated from well tests is compared with that estimated from radon tracer. Significant difference between the two estimated values of fracture permeability indicates the heterogeneity and range of variation in a naturally fractured reservoir. The value estimated from well tests represents the permeability of highly fractured flow path; the value estimated from radon tracer represents the average permeability of entire fractured reservoir. A quantitative means is presented in this paper to estimate fracture porosity and permeability using radon tracer.
