Class VI Injection Well Step Rate Test Procedural Recommendations
This white paper provides an SRT method and procedure that has been accepted by regulators for determining the MAIP. An SRT consists of a series of injection rate steps each held for an equal time duration, with each injection rate progressively increased. Results are plotted and analyzed to observe the formation pressure response. An extended injection test at a constant rate followed by a pressure falloff test is recommended after the SRT.View/Download Document
