SAUDI ARAMCO: MULTI-FUNCTIONAL NANO-TRACERS WITH IN-SITU DETECTION

摘要

Chemical and radioactive tracers have been used for decades in the oil industry to track injected fluids as passive (to map interwell permeable paths) and active (by detecting residual oil saturation tracers). These conventional tracers have many drawbacks, including: 1. High cost (about $3,000/kg); 2. Time-consuming sample collection with high safety hazards for both collection and transportation; and 3. Lengthy laboratory analysis (about eight weeks), which often can mean loss of data integrity.
