Fiber Crack Resistance Test

Fibers have proved reinforcing cement when the stone is hardened. It is especially important when downhole forces during drill-out, perforation, pressure testing, etc. will act directly on the cement. Broken cement chunks may fall on top of downhole equipment, BHA and/or damage surface equipment, hence endangering the whole process.
