Testing process for testing zero emission hydrocarbon wells in order to o btain general information on a reservoir, comprising the following steps: in jecting into the reservoir a suitable liquid or gaseous fluid, compatible wi th the hydrocarbons of the reservoir and with the formation rock, at a const ant flow-rate or with constant flow rate steps, and substantially measuring, in continuous, the flow-rate and injection pressure at the well bottom; clo sing the well and measuring the pressure, during the fall-off period (pressu re fall-off) and possibly the temperature; interpreting the fall -off data m easured in order to evaluate the average static pressure of the fluids (Pav) and the reservoir properties: actual permeability (k), transmissivity (kh), areal heterogeneity or permeability barriers and real Skin factor (S); calc ulating the well productivity.
