SureRock™ enhanced sidewall coring solution

Learn how SureRock solution enables recovering cores in reservoirs previously deemed impossible. But it’s more than just core recovery. It revolutionizes how to analyze those cores when recovered to surface—an end-to-end solution to help accelerate your field development.

Discover a new way to core.

Understand the reservoir rock and its fluid contents. Better data for better decisions.

Complementing logging and wireline formation testing, sidewall coring is a faster, cost-effective alternative to conventional cores and avoids the ambiguity introduced by the depth uncertainty of drill cuttings. Rotary sidewall cores are recovered with miniature diamond-tipped drill bits that preserve the rock pore structure when they cut a round plug of the formation directly from the borehole wall. Because rock integrity is maintained, a wealth of geological, geomechanical, and petrophysical data can be obtained through laboratory analysis of the sidewall cores.
