The variation of permeability with depth can be probed indirectly by various means, including hydrologic models that use geothermal data as constraints and the progress of metamorphic reactions driven by fluid flow. Geothermal and metamorphic data combine to indicate that mean permeability (k) of tectonically active continental crust decreases with depth (z) according to log k ! )14–3.2 log z, ...

This paper presents a Buckley-Leverett analytical solution for non-Darcy displacement of two immiscible fluids in porous media. The multiphase non-Darcy displacement is described using a Forchheimer equation or other non-Darcy flow correlations under multiphase flow conditions. The analytical solution is used to obtain some insight into the physics of displacement involving non-Darcy flow effec...

The forecast for oil production from an reservoir is made with the aid of simulations. model parameters in simulations are uncertain whose values estimated by matching simulation predictions history. Bayesian inference (BI) provides a convenient way estimating mathematical model, starting probable distribution parameter and knowing BI techniques history require Markov chain Monte Carlo (MCMC) s...

A study of the reservoir characteristics Tournaisian formation in Yablunivske oil and gas condensate filed shows that pore structure this area is complex permeability varies widely. Based on logging response characteristics, core analysis data curves GR, DT normal resistivity curves, mud content, porosity, permeability, bound water saturation parameters were calculated by statistical regression...
