Relating pore fabric geometry to acoustic and permeability anisotropy in Crab Orchard Sandstone: A laboratory study using magnetic ferrofluid [PDF]
, 2003 Pore fabric anisotropy is a common feature of many sedimentary rocks. In this paper we report results from a comparative study on the anisotropy of a porous sandstone (Crab Orchard) using anisotropy of magnetic susceptibility (AMS), acoustic wave ...

Evaluation of mineralogy per geological layers by Approximate Bayesian Computation
, 2019 We propose a new methodology to perform mineralogic inversion from wellbore logs based on a Bayesian linear regression model. Our method essentially relies on three steps.

Energy Science &Engineering, EarlyView.On the basis of core and log data, a Bayesian‐Optimized Random Forest model achieved 92.76% accuracy in classifying tight sandstone reservoirs. A gray relational analysis‐derived evaluation index shows > 80% consistency with actual gas zones. ABSTRACT Tight sandstone gas (TSG), an unconventional oil–gas resource, has heterogeneous reservoirs ...

Journal of Applied Sciences and Environmental Management, 2023 Petrophysical properties are used to characterize a reservoir. Hence, this study evaluates petrophysical properties of the Sapele shallow field in the Niger Delta Area of Southern Nigeria with the aid of log data such as gamma-ray, density, neutron, and
