A process for killing and suspending mixtures of hydrocarbonaceous fluid production, particulary oil, in a formation containing same which minimizes formation damage. First, a "spacer volume" of liquid containing a surfactant is directed into the formation's productive interval. Thereafter, a solidifiable pumpable gel mixture is placed via a wellbore into the formation's productive interval and also within said wellbore. Said mixture solidifies in the formation and forms a gel plug within the wellbore. Thereafter, a light weight cement is placed over said gel plug effectively "Killing" and suspending the production of hydrocarbonaceous fluids.
