Polypropylene fiber has a significant effect on reducing the porosity and the permeability of the base cement. cement formulation polypropylene fiber...

... Abstract Source rock reservoirs have complex mineralogies and pore systems–their porosity varies from low to moderate, and their permeability varies from low to ultra-low and is in the nano-darcy range. The petrophysical evaluation of these complex reservoirs using only conventional logging...

... transverse relaxation time (T 2intrinsic ) spectrum was unaffected. Consequently the, T 2intrinsic spectrum was used to determine partial porosities and fractional fluid volumes. However, the total and effective porosities were not seriously impacted. 2D NMR (T 2intrinsic – Diffusivity) maps were used...
