This research aims to decrease the cost of last production stages
through decreasing the cost of potential casing repair by avoiding the
problems that casing string may be exposed to. Such problems are
caused by the temperature effect of salt dril
ling fluids as well as other
fluids normally existed in the annular behind casing at the nonecemented
intervals.
This research aims to increase the production lifetime of oil and gas
wells through avoiding the problems that production casing string
may be exposed to. Such problems are caused by the effect of different
drilling fluids as well as other fluids normally existed in the annular
behind casing at the none-cemented intervals.
