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 ...

The volume of shale (Vsh) is a critical parameter in petrophysical analysis that enables the accurate estimation other parameters like effective porosity, saturation and Net-to-Gross. This an important step characterization reservoirs as well valuation hydrocarbon potentials. GR (Gamma Ray), Neutron Density Potassium, Uranium Thorium logs were adopted to estimate analyze Vsh for sand 4 reservoi...

The article presents the results of lithological and petrophysical investigations reservoir rocks Eocene-Paleocene Formations, which is one main hydrocarbon prolific horizons in Central Eastern Ciscaucasia. These include characteristics pore space parameters for these stratigraphic intervals.

We had found functions can be used to fix bits [2] by given differences. We use these functions build a message expansion function. In the message expansion function, there are some bits include message bits and incremental bits produced from message bits, these bits will be used as parameter of date-depend function. This message expansion function will fixed at lease n × 5 . 5 bits with given ...

The Sand beds of the Sapele field have been evaluated to ascertain viability for hydrocarbon development using integration structural play and petrophysical indices. Pay sands were delineated quick look approach. A seismic horizon interest was picked a well control measure. reveal three major faults responsible migration entrapment mechanisms which contributed three-way closure in area. Litho-s...
