| titleOfInvention | PROCEDURE FOR THE DETERMINATION OF THE PRESENCE OF BORE FILTER IN A WELL SAMPLE. |
| abstract | Process for determining the presence of sounding filtrate in a well sample characterized in that it comprises the steps of: preparing a sounding mud with a known concentration of nitrate ion, using said mud in the wellborehole; do a well test to obtain a sample of fluid; analyze the sample to determine the presence of nitrate ion and compare the concentration of nitrate found in the sample with the concentration of nitrate ion present in the drilling mud to determine the invasion of the liquid sample by the drilling mud filtrate.
