During percussion sidewall coring, an explosive charge is used to fire a short core barrel into the formation at high speed. The barrel, along with a core of approximately 1" in diameter and around 1" - 2" long, is then retrieved. A percussion-core wireline tool can typically provide several dozen cores in one run. This method of coring does not yield the quality of rock material produced by conventional or rotary coring, but has the advantage of being a much faster and less expensive way to retrieve rock material.
