A new method to construct reservoir capillary pressure curves using NMR log data and its application;

Based on modern nuclear magnetic resonance log (nmrl), porosity interpretation model is improved and then a new approach to calculate the volume and capacity is pointed out by using cur data and conventional log data together.

This paper discusses a method of using nuclear magnetic resonance log (NMR) in formation damage e-valuation.

Being a fast developed new technology, nuclear magnetic resonance logging technology has become an important method to evaluate all kinds of reservoirs and distinguish oil and gas.

Using resistivity ratio of induction/laterolog-acoustic slowness crossplot,accurate calculation of irreducible water saturation,and application of array induction logging and nuclear magnetic resonance logging,a set of log interpretation and evaluation methods of low resistivity reservoir.
