Based on the fact that NMR T 2 distribution and capillary pressure curves can reflect the
reservoir pore structure, a novel method was presented to calculate reservoir permeability …

Tight sandstone gas zones displayed such characteristics as low porosity and low
permeability. At present, it was a challenge for log analysts to gain reservoir absolute …

It is very important to understand reservoir pore structure information in finding interested
zones and formulating advisable recovery scheme. Capillary pressure data is critical …

By analyzing hundreds of capillary pressure curves, the controlling factors of shape and type
of capillary pressure curves are found and a novel method is presented to construct capillary …

Nuclear magnetic resonance (NMR) core experimental analysis is a new developing
technique in experi-mental geology. Based on the principles and methods of NMR core …

Predicting permeability from nuclear magnetic resonance (NMR) logging data using SDR
model and Coates model provides a quick and relatively reasonable value for reservoir …

It has been a great challenge to determine permeability in tight gas sands due to the
generally poor correlation between porosity and permeability. The Schlumberger Doll …

The relative permeability (K r) measurement of tight sandstones is challenging due to its low
porosity, low permeability, and complex pore structure. Nuclear magnetic resonance (NMR) …

It is difficult to accurately obtain the permeability of complex lithologic reservoirs using
conventional methods because they have diverse pore structures and complex seepage …

Permeability, irreducible water saturation and other information associated with the pore
size, such as capillary pressure, are very important input parameters in tight gas reservoir …
