contact us· HOUSTON–Natural gas wells are often thought of as free flowing with no need for artificial lift. However, many gas wells produce some liquids–condensate, water or both–at some stage in their life cycles. If this liquid is not removed from the well, it will accumulate in the well bore, inhibit gas production and limit the ultimate recovery of gas from the reservoir.
