Abstract
  Estimation of rock type, porosity and saturation are the main applications of petrophysical logs. Several equations are presented for mentioned estimations, and deficiencies of these equations are widely investigated. In this paper, general deficiency of well logs processing methods is discussed.

Volume 23, Issue 90 , March 2014, , Pages 239-246

https://doi.org/10.22071/gsj.2014.44008

Abstract
  Rock physics is the major tool to describe physical property of reservoir rocks; such as porosity, permeability, degree of saturation, property fluid that saturated, shape of pores, compressibility and etc via studying ultrasonic wave transmitting through a rock sample. Between these parameters, porosity ...  Read More
