摘要： The present invention relates to a method of breaking an aqueous based viscosified fluid having potassium ions present therein with a breaker comprising an alkali metal chlorite or hypochlorite through use of a breaker activator comprising a source of ammonium ion in the aqueous fluid. The method is particularly effective in providing a controlled break in a treatment fluid introduced into a subterranean formation having a static temperature in the range of from about 100.degree. F. to about 300.degree. F. In some instances, a second breaker activator comprising a source of thioglycolate ion also may be admixed with the viscosified fluid to further accelerate breaker activation at temperatures below about 200.degree. F.

摘要： The present invention relates to a method of controllably breaking an aqueous based viscosified fluid containing a gel stabilizer such as sodium thiosulfate, when the fluid is within a subterranean formation having a temperature above about 175.degree. F. The method is accomplished by the incorporation of a particular selected breaker comprising an alkali metal chlorite or hypochlorite in the viscosified fluid containing the gel stabilizer. The method is particularly effective in providing a controlled break in a treatment fluid introduced into a subterranean formation having a static temperature in the range of from about 200.degree. F. to about 300.degree. F.

摘要： It has been discovered that carbonate powders and bicarbonate powders are useful to increase the pH and corrosion resistance of high-density brines, such as zinc bromide brines, without significantly reducing their densities. The carbonates and/or bicarbonates should be water-soluble and may be sodium, potassium, magnesium and/or ammonium carbonates and/or bicarbonates and the like. The carbonates and/or bicarbonates are easily added in powder or other finely divided solid form and are completely dissolved in the brine prior to pumping the brine into a subterranean formation.
