Norwegian Barents Sea multi-well QEMSCAN (QS1) stratigraphy/provenance/engineering/drilling studyC. Augustsson, A. Escalona, H. Hodne, P. Nadeau, T. Puntervold, S. Strand
Project goals: Train Engineers & Geoscientists to create an integrated multi-well database, characterize basin-fill geohistory, tectonic evolution, provenance and drilling records for key Barents Sea/NSC wells, develop wellsite support for cutting analysis to increase drilling efficiency, safety and environmental performance.
Partners: FEI, Heavy Mineral Research Associates/University of Aberdeen, ArkadiaGeoScience AS, & Well Logging Services candidates, NPD-Well cuttings/cores.
Seeking support for Analytical facilities, Research assistants, MSc/PhD projects, 10-20 candidate wells, 5-10k samples.See poster & project link:http://force.org/en/IE/Project-groups/Projects---Improved-Exploration---overview/

Drilling Efficiency, Safety & Performance
C. 80% of Drilling Problems/Incidents Related to Borehole Stability Issues
QEMSCAN Wellsite (QSW) gives Early Warning of Caving, & Identifies the Source Interval(s) with High Confidence
QSW Detects Drilling Components, Equipment Breakdown Debris & Mechanical/Chemical Failures
Estimates for c. 3-30 saved drilling days per well depending on Depth, Temperature, Pressure and Sub-Surface Conditions
Safety & Environmental Performance Improvements also Expected, and with Increased Competence/Experience

Reduced Drilling Costs & Exploration/Production Competiveness
C. 50% of all exploration/production cost are related to drilling Greatest Safety and Environmental Risk Exposures also related
to NSC drilling operations QSWellsite has the potential when effectively implemented by
trained engineer/geoscience teams to reduce overall NSC costs by an estimated 10-40%
Major Safety/Environmental Risk Exposure Reductions Provides Key Sub-surface data for Enhanced Exploration
Efficiency, Basin/Play Analysis, & Discovered Volumes
