reshade image enlarger 3.0 full crack ips cracking tips One of the key problems in modelling flow in oil reservoirs is our lack of precise knowledge of the variations in flow properties (e.g. permeability) across the field. At best we can infer the statistics of these variations from field observations or analogue outcrops. The challenge is then to determine the statistics of the flow itself (flow rates, pressures etc.) from the statistics of the permeability variations. These calculations are conventionally done by Monte Carlo simulations. use of crack software We aim to demonstrate the use of a path integral formulation for this problem. Originally developed by R. P. Feynman as an alternative formulation of quantum mechanics, it has become a tool for use with stochastic differential equations (see, for example, Ref. [1]). To demonstrate how this methods works, we start with the one dimensional Darcy flow problem: q(x)=-K(x)dp(x)/dx where p(x) is the pressure, q(x) is the flow rate and K(x) is the rock permeability. The randomness of the porous medium is modelled by regarding K as a stochastic quantity which is assumed to follow Gaussian statistics [2]. Because of the randomly varying rock structure, there is a variety of conceivable pressure realisations p(x). The path integral Z is an integral over all realisations with an appropriate probability measure. Once Z is evaluated, either analytically, or by standard Monte Carlo methods [3], any observable of interest, including pressure correlations can be easily obtained. portable penetrator wifi wep wpa wpa2 wps cracker Extension of our approach to three dimensions requires simulated annealing. In all dimensions, the agreement between the conventional method and the path integral method is very good.
