Title
(EN) METHODS FOR REDUCING CONDENSATION
(FR) PROCÉDÉS DE RÉDUCTION DE CONDENSATION
Abstract
(EN)
A method for reducing condensate in a subsurface formation is disclosed. The method comprises introducing a first reactant and a second reactant into the subsurface formation. The first reactant and the second reactant produce an exothermic reaction that increases temperature and pressure in the subsurface formation to greater than a dew point of the condensate. Increasing the temperature and pressure in the subsurface formation to greater than the dew point of the condensate vaporizes, and thereby reduces, condensate in the subsurface formation.
(FR)
La présente invention concerne un procédé de réduction de condensats dans une formation souterraine. Le procédé comprend l’introduction d’une premier réactif et d’un second réactif dans la formation souterraine. Le premier réactif et le second réactif produisent une réaction exothermique qui augmente la température et la pression dans la formation souterraine au-delà d’un point de rosée du condensat. L’augmentation de la température et de la pression dans la formation souterraine au-delà du point de rosée du condensat provoque une vaporisation du condensat, et réduit ainsi ledit condensat dans la formation souterraine.
