Summary

A new approach to testing of oil and gas wells by means of sinusoidal oscillations in flow and pressure instead of the traditional buildup test is proposed in this article. This approach allows faster testing and simultaneous testing of several wells, with no need for a dedicated test header; it can also be adjusted to strike an appropriate compromise between measurement precision and production loss. This study details various operating issues such as generation of input signals, choice of test frequencies, applicability, and interpretation of results. To demonstrate the method, both a synthetic test and several field tests are presented.
