In underbalanced drilling, the wellbore pressure inside the annulus is to be kept less than that of the reservoir pressure. This allows reservoir influx...

Introduction The phase behavior characteristic of gas condensate reservoirs is that as reservoir pressure drops below the dew point of the gas, liquid condensate is formed in the reservoir. Some of this liquid dropout may be trapped in the pore spaces and not be recoverable. Thus...

In a recent paper 1 , the mechanisms that lead to this increased productivity were outlined and the suitable reservoir types conducive to cold production techniques were identified. In this paper, these mechanistic concepts are extended to practical...

Production declines are difficult to interpret since production losses could be due to a lack of reservoir pressure, increasing near wellbore damage, relative permeability effects or the transition from transient to steady state flow.
