... Abstract Modeling of chemical tracers represents one of the most powerful dynamic tools for reservoir characterization and estimation of oil saturation. However, the continuous monitoring during long times in partitioning inter-well tracer tests (PITTs), which extend to months or years in some...

... and in geothermal reservoirs. This paper describes performance test of NSA as chemical tracer in oil reservoir in direct comparison with proven conservative tracer, FBA by pairing an NSA tracer with a proven FBA tracer in the same injector well as part of IOR polymer pilot project. Six different types of NSAs were...

... Abstract Single well chemical tracer tests (SWCTT) have been extensively used in the field to estimate residual oil saturation in a reservoir for more than 50 years. They are often used as characterization methods to gauge EOR potential/performance. Therefore, an accurate estimation of S...

... analyses were used to make quantitative comparisons of both processes and allowed for several technical insights. This is the first time in literature that a quantitative comparison of surfactant-polymer flooding and polymer flooding alone has been presented. chemical tracer enhanced recovery...

... desaturation. The one-spot EOR pilot described in this paper was successfully executed by performing two Single-Well Chemical Tracer (SWCT) tests. For the first stage of the pilot, 200 bbl of produced water (up to 166,000 ppm TDS) were injected into the test well in an attempt to displace mobile oil out...

... Abstract The single-well chemical tracer test (SWCTT) is widely used in the determination of residual oil saturation (SOR) in the near-well region. SWCTTs typically require large amounts of chemicals and some days of well shut-down. In the present paper, we propose using thermo-sensitive...

The chemical tracer test was used to determine the residual oil saturation, which usually is not available in Arbuckle reservoirs as no waterflooding application was reported...

... Abstract Single well chemical tracer test is a technique for measuring residual oil saturation in a reservoir. For enhanced oil recovery applications, like waterflooding and chemical flooding (polymer/surfactant), it is essential to evaluate the efficiency of the process by determining...

... Abstract Single Well Chemical Tracer Tests (SWCTT) are widely used to estimate the remaining oil saturation after waterflooding (Sorw) and enhanced oil recovery including low salinity waterflooding. SWCTT have the advantage of being a more direct measure of Sorw than logs and unlike cores do...
