RESERVOIR CHARACTERIZATION

Native State. Measurements made at native state conditions. The tracers operate in native-state wetability pore space contacting live crude oil, live water at reservoir temperature. The problems that make laboratory measurement of these parameters difficult are easily overcome by carrying out the measurement in situ.

Cost Effective. The entire series of tests can be carried out typically in less than 2 months at a cost similar to comparable laboratory work.

OPERATIONAL STEPS

1.	Measure connate water saturation by injection and production of oil plus tracers.
2.	Inject a small volume of water plus tracers to displace oil and measure fractional flow.
3.	Water out zone and measure residual oil saturation by tracer method.
4.	Return well to oil production status.
