The MSCT mechanical sidewall coring tool reliably recovers up to 50 sidewall core samples in a single trip. Optional configurations can recover up to 75 cores or 20 core-catcher samples.

Confirmed sample acquisition

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. Each sample is isolated in the tool for positive identification, and a summary output at surface lists all samples with the exact depth and time that each was taken.

Preserved sample integrity

Because sidewall cores can be drilled from a wide variety of lithologies—hard, brittle igneous rocks to friable sandstones, cemented carbonates, and ductile shale plays—they avoid the damage associated with percussion coring tools.

Applications:

• Lithology analysis
• Secondary porosity analysis
• Porosity and permeability determination
• Confirmation of hydrocarbon shows
• Determination of clay content
• Determination of grain density
• Lithology determination
• Detection of fracture occurrence
