More than 300 Wells have been completed in porous carbonate rocks in Xinjiang region, Halfaya in Iraq, KEC block 9, Kazakhstan and other areas, and the production enhancement was remarkable.


The target zone of MXX well is fractured limestone, porosity 15.8%,permeability 3.14 mD, use multi-stage perforation + high pumping rate + large acid volume of 3 stages alternate injection with fiber temporary plugging, and with liquid nitrogen injection, total fluid volume 289.2 m³,liquid nitrogen 15.8 m³, self-degradation fiber 200 kg, the production rate increase 2-3 time with almost no water production after stimulation.
