  • COMBINED TREATMENT PROCESS FOR REMOVING AND INHIBITING SCALE
    Publication number: 20230002667
    Abstract: The present invention proposes a combined treatment of scale removal and inhibition in reservoir rock (inhibition squeeze), by using inhibitors derived from organophosphonic acid, in acidic medium, aiming at minimizing the intervention time in well scale mitigation operations, in addition to reducing costs per treatment and the risks associated with the process.

  • ARRANGEMENT OF A LASER RADIATION FOR CATALYSIS IN COMPLEXATION REACTIONS
    Publication number: 20220410317
    Abstract: The present invention addresses to an adaptation of a laser system in a reactor for the application of laser radiation, promoting the thermal catalysis of the complexation reactions of barium sulfate (BaSO4), strontium sulfate (SrSO4) and CaCO3 with application in fields of drilling and completion of wells, as well as lifting and draining systems; in this case, aiming at the removal of scale at an appropriate temperature for the complexation and consequent dissolution of the scale salt in subsea equipment of the production systems.
