Abstract
The present invention relates to an autonomous chemical treatment system and method for drilling and completion probes, so that it allows the probe to carry out chemical treatments in subsea wells, dispensing the need to use the WSSV, which has a limited treatment capacity due to tank volumetry, generally smaller that the marine probes.
