... Abstract The results of stimulation treatments in southern Mexico's carbonate reservoirs have been significantly improved using a new fiber-assisted, self-diverting acid system. These reservoirs are thick, deep, and hot. Depths are usually greater than 15,000 feet, bottomhole temperatures reach...

... closure stress and conductivity measurement taken at different loads. Experiments clearly show that acid refracturing performance is influenced by the acid system. Enhancement of conductivity with acid refracturing depended upon the acid system with greatest enhancement with plain HCl and even...
