Self-healing cements – the key to maintaining the integrity of cement sheath. Part 1

To control water production, it is necessary to seal the channels of 20–25 mm thickness in the cement sheath at a depth of hundreds and thousands of meters. The most promising solution is the use of self-healing cements. The concept of self-healing materials has been known since the 1980s due to th...
