  • Patent number: 12319873
    Abstract: A diverter acid fluid composition for use in the stimulation of oil wells during exploration thereof, named Quovadis is disclosed. The diverter acid fluid may be used for stimulating oil wells during matrix acidification. The role thereof is to improve the efficiency of processes of stimulation of wells by acid treatment allowing the fluid to come into contact with regions of low permeability of the carbonate rock matrix, i.e., regions of difficult access. The diverter acid fluid also removes permanent formation damage around the well, allowing for greater coverage of the treatment and, consequently, better use of the treatment.
