Nexus Acid Enhancer is an environmentally friendly single phase Hydrochloric Acid retarder that improves wormhole penetration and reservoir contact during acid fracturing and matrix acidisation.

Calcite reservoirs represent a significant portion of hydrocarbon resources in subterranean formations. Most acid-based stimulation treatments for carbonate and sandstone reservoirs – particularly those under high temperatures – encounter a fundamental problem, in that the etching rates are so fast that the treatment fluid is fully expended before it can penetrate deeper into the formation, resulting in an ineffective matrix treatment. Nexus Acid Enhancer modulates the critical etching rate of Hydrochloric Acid so that it can penetrate deeper into the formation, generate a more extensive and robust wormhole network, and foster higher production.
