Application of Horizontal Wells To Reduce Condensate Blockage in Gas/Condensate Reservoirs Academic Article uri icon


  • Much of the world's gas reserves can be found in gas/condensate reservoirs. These reservoirs, from a recovery and deliverability standpoint, can have significant differences from oil reservoirs. When the pressure, either in the wellbore or in the reservoir, drops below the dewpoint pressure, a condensate phase appears that reduces gas production significantly. In this study, horizontal wells were used in a giant gas/condensate reservoir (North field, Qatar) to reduce the condensate blockage. Critical questions are: What fraction of a horizontal well's increased gas production results from the increased formation contact and what fraction results from reducing condensate blockage?.
