The National IOR Centre of Norway, SWCTT, oil saturation, SOR

Synopsis

The main objective has been to improve the prevailing single-well chemical tracer push-and-pull technique, SWCTT, for measurement of residual oil saturation (SOR) in defined pay zones in a single well test [1,2,3] after water injection on the following subjects:

   • Improvement in tracer detection limits by a factor > 1000
   • On-site or even on-line detection of tracer signal in true time
   • Reduction in the needed amount of tracer by a factor of > 1000
   • Reduced footprint on production platforms during tracer operation

The intended audience and technology users are oil and service companies.
