ABSTRACT:
A logging while drilling (LWD) and measuring while drilling (MWD) method is disclosed for analyzing the porosity of geologic formations containing carbonate-formations. The method is based on a combination of T1and T2measurements that enables detection of diffusivity coupling and permits more accurate determination of pore size distribution, formation permeability and irreducible water saturation.
