149. In the case of fluid kicks or during drill-stem tests, the authorization holder must collect samples and must analyze the petroleum and groundwater encountered.
In the case of gas, the analyses must, in particular, identify its composition and, where necessary to differentiate a number of formations, characterize the carbon isotope ratios.
In the case of oil, the analyses must, in particular, identify its composition and characterize its viscosity and density.
In the case of groundwater, the analyses must, in particular, identify its composition in dissolved solids and petroleum and its physical characteristics, including the pH, the conductivity and the cloudiness.
The Minister may exempt the authorization holder from the requirement to collect certain samples where the Minister considers that he or she already has sufficient data to characterize the reservoir or the sealing rocks.
A holder who collects a sample must ensure to use a method preventing contamination of the sample.
