Laboratory Study of Production Mechanisms Application to a Gas Condensate Reservoir

摘要

Laboratory simulations of the primary depletion of a critical hydrocarbon mixture carried out on long petrophysical models in conditions nearest possible to field conditions were performed in order to study the production mechanism. This is a complex mechanism in which the gravity forces are stronger than the capillary ones in spite of the weak matrix permeability. They show that an exploitation by primary depletion can be used for the studied field. In this field, the particular properties of the initial fluid (critical gas condensate system) can assume a good recovery, like a classical type field produced by pressure maintenance, but respecting two conditions: production by the bottom of the formation and production at a flow rate in order to allow gravity and fractures to have a favorable effect.
