Adjusted Flow Time
Definition - What does Adjusted Flow Time mean?
Adjusted Flow Time is the estimated flow time that is used in the well testing phase of oil and gas production. It is the flow time used during a well test to check the difference in the flow rate before, during or after the well test. Adjusted Flow Time is measured as: t = cumulative well production divided by the flow rate of a well before shut-in. The cumulative production rate is taken since the last shut-in span. Whereas, the flow rate is taken prior to the shutting off of the well for a buildup test.
Petropedia explains Adjusted Flow Time
During the well testing phase, an oil well needs to be tested for its production capability. Adjusted Flow Time is a factor that helps engineers to understand the flow rate of the well. It is an approximate flow time that determines the variation in the flow rate that occurs before or during the well test. To find out the Adjusted Flow Time, cumulative production as well as the last flow rate of the well is important. It is calculated by dividing the previous cumulative production value with the last flow rate of the well. The Adjusted Flow Time is denoted by t.
