DiscovOre Prime P Surface

The DiscovOre Prime is a revolutionary coring system developed for drillers by drillers that is safer and faster than other available systems.

SAFETY

Like the regular DiscovOre, the Prime has built-in safety features that automatically engage and do not require additional manual steps, making it easier to assemble and disassemble. Lighter than the regular DiscovOre in P size, the Prime is easier for drillers to handle.

- No spring pins and no spearhead	- Automatic locking overshot
- Robust latches and spindle	- Improved conversion head for all hole orientations
- Improved latch engagement	- Stabilized bearing assembly

SPEED

Additionally, the Prime is faster than the DiscovOre, with a descent speed that is up to twice as fast as the L-Latch. Its increased inner tube retrieval speed leads to a quicker drilling cycle time and less wear and tear on wireline.

PRODUCTIVITY

The DiscovOre Prime is a premium product with a payback that can be achieved within a couple of days depending on drilling conditions. Contact your sales representative to inquire about the return on investment specific to your operations.

DiscovOre: A Different Core Barrel System
