The standard configuration of the rotary MSCT mechanical sidewall coring tool reliably recovers up to 50 sidewall core samples. Optional configurations for recovering 75 core or 20 core-catcher (dictated by core-catcher capacity) samples are available. Each sample is isolated for positive identification, and a summary output at surface lists all samples with the exact depth and time that each was taken.
The real-time display at the logging unit confirms proper tool operation and sample acquisition. The MSCT tool is run in combination with a gamma ray tool to correlate with openhole logs for accurate, real-time depth control of the coring points.
Because the sidewall cores can be drilled from a wide variety of lithologies—from hard, brittle igneous rocks to friable sandstones, cemented carbonates, and ductile shale plays—they avoid the damage associated with percussion coring tools.
