SureCore Real-Time Measurement While Coring


The SureCore  is a real – time coring indication system that informs the operator if the core is jammed, milling, washing or still coring throughout a coring operation. The system uses  MWD technology inside a core barrel and can be run with Halliburton, BHI, NOV and Reservoir Group coring systems. 

SureCore not only lets the operator know if the core is jammed or not,  the latest advancement in the technology now includes dynamic sensors that provides real time inner barrel rotation, vibration and temperature. All the downhole data is pulsed to surface and is communicated directly to the coring engineer, which enables the core run to be optimised. SureCore also records the data during coring and whilst tripping.  This information is crucial as it can help eliminate lost core data and provide a better understanding of what occurred during a coring operation.  

Coring has been  very much dependent on the experience of the coring engineer in interpreting surface data. However even the most experienced engineer can make mistakes when picking or missing a jam off.  The SureCore will eliminate indecision  and uncertainty during coring and therefore can save a considerable amount of lost time, lost core data or damaged core.
