... Abstract Traditional history matching involves calibration of reservoir models using well response such as production or tracer data aggregated over multiple producing intervals. With the advent of novel tracer technologies, we can now obtain distributed water or tracer arrival time information...

... Abstract Tracer testing is a powerful tool for reservoir surveillance. Conducting and analyzing an interwell tracer test before starting an EOR flood provides the specific information required to balance the pattern's swept pore volume and optimize chemical or solvent use. Tracer testing also...

... targets. Typical parameters usually provided by reservoir simulation, such as total recovery, WAG ratios, slug sizes, etc. were determined using analog data and analytical techniques due to the lack of subsurface data and detailed performance information. The design techniques presented in this paper...

... placement in the reservoir. Viscoelastic properties such as G* (complex modulus), G′ (storage modulus) and G″ (loss modulus) define the gel strength and provide structural information such as crosslinking density. These parameters are essential to design the gel formulations (polymer and crosslinker type...
