Abstract: Testing process for testing hydrocarbon wells at zero emissions in order to obtain general information on a reservoir. The process includes injecting into the reservoir a suitable liquid or gaseous fluid, compatible with the hydrocarbons of the reservoir and with the formation rock, at a constant flow-rate or with constant flow rate steps, and substantially measuring, in continuous, the flow-rate and injection pressure at the well bottom. Then, the well is closed and the pressure is measured during the fall-off period (pressure fall-off). The measured fall-off data is interpreted in order to evaluate the average static pressure of the fluids (Pav) and the reservoir properties including actual permeability (k), transmissivity (kh), areal heterogeneity or permeability barriers and real Skin factor (S). Then, well productivity is calculated.
