Sodium nitrite and ammonium chloride are the most widely used thermochemicals in the oil
and gas industry. The kinetics of this reaction when activated with acids or acid precursors …

Currently, most explored oil fields in Russia are at a late stage of development, and in order
to maintain high levels of oil production, it is rational to put into operation fields with hard-to …

Emulsification serves various purposes, including controlling the reactivity of highly reactive
chemicals. Thermochemical fluids (TCFs), such as ammonium chloride (NH 4 Cl) and …

When cold fluid is injected into low-temperature, low-pressure, low-permeability reservoirs
containing wax-bearing heavy oil, cryogenic paraffin deposition and heavy oil condensation …

The cleanup of fracturing fluids, involving polymer degradation and well flowback, is crucial
for the success of the fracturing operations and revenue generation. Breakers, such as …
