A new method for estimation formation radial effective permeability based on wireline formation testing

Testing interpreting is the most directly method to get formation radial effective permeability, but its testing cost is relatively expensive.The paper proposed a new method to get the permeability by combining wireline formation testing (WFT) to nuclear magnetic resonance (NMR) logging, based on the new method, permeability from NMR logging is calibrated by several point horizontal permeability from WFT, and then, the average permeability can be obtained by calculating average scaled NMR logging permeability, The average permeability shows both formation vertical heterogeneity and WFT effectiveness.The method had been applied in field testing, and the permeability from the method has higher precision than DST test, as well as, its cost is very low.
