Dernaika; Shehadeh Masalmeh; Bashar Mansour; Osama Al Jallad; Safouh Koronfol In carbonate reservoirs, permeability prediction is often difficult due to the influence of various geological variables that control fluid flow. Many attempts have been made to estimate permeability from...

...Xiongyan Li Due to the complexity of lithologies and pore types, the permeability calculation of complex carbonate reservoirs has always been a difficult problem. To accurately calculate the permeability of complex carbonate reservoirs, a data mining technique is introduced. The technical process...

... reservoirs with vugs and fractures?" The purpose of this paper is to answer the above questions. We first explain why the values of m from core plugs and whole core are not suitable for evaluation of carbonate reservoirs by using the scale model of core plugs, whole core and logs. We then propose a new...

... cutoff s, which usually vary by rock type. The study performed in the different carbonate reservoirs yielded permeability cutoff s varying between 0.01and 1 mD. Practical examples from Tengiz, Karachaganak, PZ, West Africa and Permian basin validate the consistency between methods and the validity...

... is trained was obtained from different wells in a giant carbonate reservoir that covers a wide range of values. To translate the FN model into a simple mathematical form, neural functions and empirical coefficients were extracted from the trained FN model. This allowed us to develop FN-based equivalent...
