Abstract
A process for killing and suspending mixtures of hydrocarbonaceous fluid production, particularly oil, in a formation containing same which minimizes formation damage. First, a 'spacer volume' of liquid containing a chemical blowing agent is directed into the formation's productive interval. Said blowing agent decomposes in the formation and generates gas sufficient to force hydrocarbonaceous fluids away from a wellbore in said formation. 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.
