A scale removal agent may effectively be introduced into a well having a formation temperature of 300° F. The scale removal agent is a component of a gelled fluid containing an amine oxide viscoelastic surfactant.

Methods for transporting scale removal agents into a well

A fluid for use in hydraulic fracturing contains underivatized guar or a guar gum derivative as viscosifying or gelling polymer, a crosslinking agent, carbon dioxide as foaming agent and urea and, optionally, a bifunctional organic compound containing at least one hydroxyl group and at least one quaternary group and, optionally, a non-gaseous foaming agent. The fluid may be characterized by a low pH such as a pH than or equal to 3.0 and less than or equal to 5.0.

Methods of using energized well treating fluids

A gel composition for use in treating subterranean formations is provided. The gel composition is a non-aqueous based oil gel system that can include a hydrocarbon liquid capable of gelation, a phosphate ester, and a cross-linking agent. The gel composition can include the oil gel which results from adding a phosphate ester, a crosslinking agent and a delay additive to the hydrocarbon liquid.
