ABSTRACT:
A method of preventing gas coning or fingering from a gas cap in an oil producing well is provided. A silicate solution and a delayed activator are injected into the gas cap under conditions such that the activator causes the silicate to gel after a predetermined period of time to form a substantially impermeable zone or layer above the oil bearing formation to prevent gas from flowing into the oil well during production.
