The map of permeability distribution in the reservoirs is considered one most essential steps geologic model building due to its governing fluid flow through reservoir which makes it influential parameter on history matching than other parameters. For that, petrophysical properties that are tuned during matching. Unfortunately, prediction relationship between static petrophysics (porosity) and ...

Geostatistical modeling of petrophysical properties is a key step in modern integrated oil and gas reservoir studies. Recently, generative adversarial networks (GAN) have been shown to be a successful method for generating unconditional simulations of poreand reservoir-scale models. This contribution leverages the differentiable nature of neural networks to extend GANs to the conditional simula...

Hydraulicproperties of soils could play an important role in affecting the partitioning precipitation critical zone. In addition to traditional approaches, last two decades, many geophysical methods have been used aid hydrologic characterization and measurement geological materials. particular, self-potential (SP) method shows great potential these hydrogeophysical applications. The objective t...

In this article objective have been made to reviews different geostatistical methods available to estimate and simulate petrophysical properties (porosity and permeability) of the reservoir. Different geostatistical techniques that allow the combination of hard and soft data are taken into account and one refers the main reason to use the geostatistical simulation rather than estimation. Uncert...

We developed several novel two-dimensional (2D) NMR core analysis techniques, which not only enhance the analysis of fluid-saturated rock samples, but also open up an unexplored area for petrophysical research. This is different from the conventional one-dimensional (1D) NMR core analysis, in which only the proton population versus relaxation times, i.e., T1,2 distribution, is displayed to char...

Abstract During the conventional petrophysical interpretation fixed (predefined) zone parameters are applied for every (depth intervals). Their inclusion in inversion process requires extension of a likelihood function whole zone. This allows to define extremum problem fitting parameter set full interval model layers crossed by well, both associated with depth points (e.g. porosity, saturations...
