This document introduces the cross-hole sonic logging test principle, methods and interpretation. Based on practice at Ras Markaz Crude Oil Park Project in Sultanate of Oman, cross-hole sonic logging test is used to detect the integrity of concrete secant piles for seawater intake well, which points out its role in concrete quality control for cast-in-place pile, and demonstrates that the cross-hole sonic logging test method is highly efficient, accurate, and costless.
