Paper Number: SPWLA-2025-0010
... ABSTRACT NMR log relaxation time distributions (T2 or T1) are essential for deriving petrophysical properties such as porosity and pore structure. However, their accuracy is often constrained by factors such as data quality, activation sequences, and inversion techniques. Traditional...

... calculation of the sample's internal porosity. Integrating this analysis with advanced mathematical statistical methods facilitates a thorough evaluation of the sample's internal pore structure and fluid distribution. Analyzing the T 1 spectra alongside imaging facilitates a direct assessment...

...) and porosity, and acoustic PAR provides an indicator of the effect of dolomitization on rock quality. Integration of these analyses indicates that dolomitization alters rock quality through changes to pore structure, including PAR, pore size, and porosity. The main objective of this study is to further test...

Paper Number: SPWLA-2025-0039
... ABSTRACT The estimation of permeability from well logs is a challenging task in formation evaluation. The models usually employed calculate permeability from a function of porosity. The average permeability of an interval will be underestimated when using low-resolution porosity logs, which...

... and permeability. To obtain a reliable interpretation, it was essential to have precise knowledge of reservoir characteristics, such as total porosity, permeability, connate water salinity, and Archie's coefficients (m and n). These properties play a vital role in defining water saturation and in predicting...

... underbalanced coil tubing drilling. As well known, various polarization mechanisms give rise to the dielectric effect at LWD frequencies and make the dielectric permittivity especially dispersive at this frequency range. In addition, formation porosities may be derived from wireline (WL) dielectric...

... of the components. For example, one can construct a rock with 60% calcite shrubs with an average radius of 200 micrometers and a standard deviation of 50 micrometers, with 30% dolomites among them, resulting in 10% inter-crystalline porosity. Subsequently, the calcite shrubs can be partially dissolved or replaced...

... solubility in water was investigated by dissolving CO 2 in brine and then aging carbonate rock samples in the carbonated brine. The aging was conducted at 2,500 psi and 90°C for 1-, 3- and 6-month periods to simulate reservoir conditions. Petrophysical measurements of porosity, permeability, ultrasonic...
