Previous drilling result shows that the lithology, pore size, porosity, moveable oil volume, etc. vary greatly in different fault units. To better reveal the characteristics of this offshore...

... common approach to determine irreducible water saturation and free fluid porosity in the laboratory and borehole using of T 2 cut-offs. Since the transverse relaxation time, T 2 , is related to the size of pores and throats, then such T 2 values can be chosen, below which all fluids will be belonging...

..., we propose a novel interpretation method that utilizes machine learning algorithms to perform carbonate porosity partitioning (micro, meso, and macro) using standard log measurements (e.g., resistivity, density, neutron, sonic, and gamma-ray). We trained the machine learning model in key wells...
