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 plays an important role in EOR by establishing a baseline for estimating incremental volume swept and recovery factor. A key limitation to tracer testing is the time required to obtain a complete interpretation of the test results. Conventional interpretation methods require observing exponential decline in the tracer concentration from all producers; depending on the pattern size and processing rate, this can take many months or years. Meanwhile, the EOR flood is delayed, thereby eroding its value and reducing the remaining oil target. We have developed a method for analyzing tracer data from relatively early times based in part on a new way to extrapolate the tracer data, providing timely information to optimize flood performance. The extrapolation can be done shortly after the peak concentration is observed in the well with the slowest response. We illustrate the extrapolation procedure using a synthetic yet realistic dataset showing that the new methods result in a good approximation at much earlier times. We then compare swept pore volumes using early time data with the (correct) swept pore volumes using the complete tracer dataset. We also discuss how early time approximations can thus provide the opportunity to optimize chemical flood performance and field start-up of EOR floods in a timely fashion.
