Abstract

A field test was conducted to investigate the effectiveness of methanol as a solvent for removing condensate blockage.On the basis of laboratory results and a single-well numerical simulation, a field test was conducted on a gas well that suffered from gradual productivity decline caused by condensate banking in the Hatter's Pond field in Alabama.The well chosen for treatment was producing 250 MMscf/D of gas with 87 BOPD of condensate.After methanol treatment, both gas- and condensate-production rates increased by a factor of two over the first 4 months and by 50% thereafter.
