SureCore™ Real-Time Coring Technology

SureCore was designed by coring and MWD personnel to solve an industry-wide problem: knowing, with certainty, when a core has jammed off or continue coring with confidence that the core is still entering the inner barrel. Its development has progressed from core-level monitoring alone to understanding what is happening to the core and equipment downhole in real-time.

The latest generation adds dynamic sensors for inner barrel rotation, vibration and temperature. Downhole data is pulsed to surface in real-time and is also recorded throughout the run and the trip, so nothing is lost.

Why it matters: coring has always depended on an experienced engineer interpreting surface data — and even the best engineer can call a jam that isn't there or miss one that is. SureCore removes the guesswork, resulting in less lost time, less lost core and fewer damaged cores. It consistently improves core recovery and de-risks coring overall.

What Operators and Coring Engineers Have Told Us:

  • "It's like an insurance policy when conducting coring operations"
  • "We only see benefits running this tool with no downside"
  • "It could save us from redrilling a formation due to not losing the coring data"
  • "Run longer coring assemblies with confidence we won't mill away valuable core"
  • "Provides confidence to attempt connections and continue coring"
  • "We would have lost lots of core if we hadn't had the SureCore"

Jam Mitigation — JamBuster™

A jammed core usually means an unscheduled trip out of hole. Specialised Oilfield Services runs the Baker Hughes JamBuster anti-jamming coring system, whose concentric inner core barrel sleeves automatically telescope if a core jams, allowing coring to continue uninterrupted. The multi-jam activation system allows up to three jam-offs before coring must be terminated.

Combining the JamBuster with SureCore provides the most complete jam-management approach available to an operator today.
