Workshop Description

Gas condensate fields are getting more important due to an increasing share of gas produced from these fields within the global structure of gas production. One of the essential problems of gas condensate field development is condensate recovery optimization. Development of depleted gas condensate fields is followed by reservoir pressure depletion and retrograde condensation of higher boiling hydrocarbons (condensate) with some dropped out in liquid phase and lost to formations due to the fact that this condensate becomes immobile regardless of further fluid flow. As a result, up to 30-60% of initial condensate reserves can remain in the formation. So far only one stimulation technique is used for condensate recovery enhancement and that is cycling-process, which is a reinjection of dry gas into the formation. However, in many cases the application of cyclingprocess is not applied due to economic and other reasons. Thus, the gas industry is in desperate need for updating existing stimulation techniques applied in gas condensate fields and is in search of new technologies to enhance condensate recovery by both, maintaining the reservoir pressure thereby preventing condensate loss to formation, and by extracting retrograde condensate already dropped out in formation.
