Core Laboratories Inc.
A specialist oilfield services company that runs laboratories to analyze rock cores, fluid, and gas samples pulled from underground reservoirs, helping oil and gas producers understand what lies beneath their wells and how to get more out of them. Founded in Dallas in 1936, Core Lab is credited with turning core analysis into a commercial service for the industry. Its name comes straight from that job—"core" being the cylindrical rock samples drilled out of the earth that its scientists study.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
