Mechanics of gas-condensate flows with non-equilibrium phase structure in porous reservoirs

Objective



Extremely unusual phenomena as yet unexplained by recent theories have been observed in some gas-condensate fields of the NIS, which were exploited under conditions of high flow rate. They consist of considerable oscillations in time of the liquid benzene well production with a large period and amplitude. During the maximum oscillation periods the condensate production is sharply increased and the exceptional importance applied to this phenomenon has been clarified.

The main questions that will be solved by this project are as follows: Under what conditions do the oscillation regimes exist? How can they be created? How can they be controlled in order to increase the condensate recovery?

Preliminary investigations show that these phenomena can be induced by a special type of dissipate structure creation in the porous layers. This object, called non-equilibrium structures and consisting in the time and spatial consequences of the evaporation and condensation domains, is induced by non-linear flow, porous medium heterogeneity and phase transition non-equilibrium.

This project will elaborate a new hydrodynamics theory, including the numerical and experimental modelling at the microlevel, construction of the macroscopic process equations, qualitative theory of structures and chaos origin, and applications for gas-condensate fields.

All studies include three main stages: laws governing the transport of gas-condensate mixtures in porous media; kinetics of gas-condensate phase transitions; and applied aspects of this theory for enhancing condensate recovery.

The following results are expected: development of the theory of relative permeabilities for gas-condensate (g/c) mixtures; development of the theory of relative inertial coefficients for two-phase flow with high rate; understanding of the kinetics of phase transitions for g/c mixtures; development of the qualitative theory of phase structure creation under g/c flow through porous media; averaged models of g/c flow with transitions between microscopic phase structures; methods of g/c well investigation; and methods of governing the g/c porous flow in order to enhance condensate recovery.
