CTI is the world's leader in Single-Well Chemical Tracer (SWCT) technology and experience.
In 1968 the single-well chemical tracer testing method was developed by Harry Deans. Charlie Carlisle, president of CTI, began working with Harry Deans performing tests in 1979.  With over 37 years of field experience we can help bring any enhanced oil recovery program from the laboratory to the field and accurately evaluate its efficiency under native reservoir conditions.
Technical Leader
Measuring Sor via the Single-Well Chemical Tracer (SWCT) method is the skill and experience trademark of Chemical Tracers, Inc. (CTI).  With over 600 field tests completed across 37 plus years in almost every oil producing region in the world CTI stands alone as the premier technical leader in this very specialized area of well testing.
Looking to the Future
We have an extensive testing portfolio performing single-well chemical tracer tests in both offshore and onshore environments.
Renewed interest in Enhanced Oil Recovery has led to vigorous demand for our One-Spot Pilot test series to provide in situ evaluation of prospective EOR techniques.
