Product Description
AP-2 is a amine-based clay stabilizer which can be used in high-performance water based drilling fluid or completion fluids. AP-2’s amine compounds on molecular chain give it a greater inhibition and can effectively restrain the hydration expansion of clay particles. It mainly depends on the special structure which firmly absorbs on the clay to reduce the layer spacing to stabilize clay and borehole. AP-2 can effectively reduce borehole instability and reservoir damage caused by clay hydration expansion. The recommend dosage is 0.5-1.0% (v/v).
