MacroSeal™
In applications where cement bond is poor but present remedial cementing can be ineffective as placement may be impossible, cement can be gas cut before it sets, and the frac gradient is often exceeded thus exacerbating existing integrity issues by creating additional leakage pathways.
MacroSeal™ is a low-viscosity fluid system that rapidly crystalizes to form an impermeable, limestone barrier stronger than existing cement. MacroSeal™ can be injected into poorly cemented intervals, is impervious to gas cut, and is placed with precision pumping systems that ensure the frac gradient is not exceeded making it a more effective solution for restoring cement integrity.
