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.
Some of the comments and feedback we receive from drilling, geology and coring people are:
This type of technology is long overdue
We only see benefits running this tool with no downside
It's like an insurance policy when conducting coring operations
This could help us understand reservoirs better in order to plan more efficiently
It could save us from redrilling a formation due to not losing the coring data
Indicate that we have not actually jammed and are just coring a hard stringer (Do Not POOH) & adjust parameters
Save time by having confidence on what is happening down hole so a quick informed decision can be made
Use the tool for more accurate depth correlation of the core
Run longer coring assemblies with confidence we won't mill away valuable coring data
Specialised Oilfield Services own all the SureCore and CLR technology patents outright.
