Coring Services

Coring System

• Coring Mechanism: We can remove an interval of core from the bottom of the hole without tripping the drill string, using core pipe sizes ranging from 1.5” to 6”, depending on the specific size
• When we are ready to remove the core, an overshot is lowered on the end of wireline thru the center of the drilling string
• The overshot attaches to the back of the inner tube, the inner tube disengages itself from the core barrel, and wireline is used to pull the core back to surface for retrieval.
• Then a second inner tube is dropped and pumped down the core pipe or drill pipe, locking into the core barrel, allowing for continuous coring runs.
