... to stimulate oil and gas wells. This work includes the measurement of the stability of emulsified acid and the reaction weight loss as a function of the concentration of these agents at different periods of heating time. The tests are conducted at 135°C with a concentration of 28 wt% HCl and an acid-to-oil...

... were found to be the most effective in stearic acid release followed by sodium, calcium and magnesium. Thermogravimetric analysis confirmed the observed trend and the calcite weight loss due to stearic acid decomposition decreased with decreasing brine ionic strength and confirmed the fact...
