In SWCT Sor testing, water with dilute chemical tracers is injected and subsequently recovered from the same well.  A natural extension of this method is to inject the tracers in oil to measure connate water saturation.  The stationary phase is accurately measured in the SWCT method.  This can be residual oil saturation or connate water saturation.  

 

We offer a complete service package of SWCT field testing. We provide custom field equipment dedicated to fluid metering, fluid injection, media filtering, and chemical tracer injection and on-site analysis.

 

Carried out on wells that produce nearly 100% oil.

 

Non-destructive, in situ method for measuring S_wc.

 

Can be carried out in cased or open hole completions.

 

Results typically represent hundreds of barrels of pore space in the test zone.

 

S_wc results usually measured within ±2 saturation units.

 

Test sequence is completed in about two-three weeks.
