Method of using gelled fluids with defined specific gravity to prevent ingress of unwanted fluids |
| abstract |
Gelled barrier fluids for preventing the ingress of undesired fluids from subsurface environments into subsurface apparatus have a specific gravity which is within 0.01 of the specific gravity of the undesired fluid e.g. sea water, fresh water or hydrocarbon; and the entire interior area of the apparatus, after being filled with the gelled barrier fluid, is free of gas. The gelled barrier fluid is preferably substantially free of gas and comprises a base fluid and a gellant system. The base fluid may be the combination of an alcohol and glycol e.g. methanol and ethylene glycol; and the gellant system may contain a viscosifying polymer and a crosslinking agent e.g. a crosslinked cellulosic or guar derivative. |
