Petrophysical properties including volume of shale, porosity and water saturation are significance parameters for petroleum companies in evaluating the reservoirs determining hydrocarbon zones. These can be achieved through conventional petrophysical calculations from well logs data such as gamma ray, sonic, neutron, density deep resistivity. The logging operations targeted limestone Mishrif Ns...

The study aims to implement a high-resolution Extended Elastic Impedance (EEI) inversion estimate the petrophysical properties (e.g., porosity, saturation and volume of shale) from seismic well log data. resolves pitfall basic EEI in inverting below-tuning resolution, dimensionality absolute value are improved by employing stochastic perturbation constrained integrated energy spectra attribute ...

The estimation of non-stationary random medium parameters petrophysical is the key to application theory in fine seismic exploration. We proposed a method for estimating using data. Based on linear model, relationship between data and porosity, clay volume, water saturation was described, principle autocorrelation parameter were introduced this study. Subsequently, specific steps applying power...

Estimation of reserves in tight gas and shale gas reservoirs is problematic due to the low to ultra-low permeability characteristics of these reservoir systems. The sole application of conventional decline curve analysis methodologies often yields erroneous reserve estimates. Therefore, the use of theoretically-based production analysis techniques has become a must to analyze well performance a...

Abstract Facies studies represent a key element of reservoir characterization. In practice, this can be done by making use core and petrophysical data. The high cost difficulties drilling coring operations coupled with the time-intensive nature have led researchers toward using well-log data as an alternative. Teapot Dome Oilfield, where are limited to those from only single well, we used for e...

This work presents a novel algorithm that achieves enhanced resolution of well logging signals, e.g., from 1 ft pulsed neutron mineralogy tool to 0.04 an imaging tool. The algorithm, denoted as “Digital Core,” combines mineralogical and sedimentological information generate high-resolution record the formation which can be consequently applied thin bedded environments. keystone philosophy this ...
