The lift gas response curve is fitted into the equation
Q.Liquid (from test) = + A * sqrt ( Q.gas ) - B * Q.gas + C
This equation is used to calculate the production rate verses injection gas
first assumed Q.gas to be injected then test the well at Q.gas assumed 500 Msacf.
repet the same procedure with different Q.gas assumed 1000 Mscf and 2000 Mscf.Finally we have three equation
for example:
700 BBl = + A * sqrt (500) - B * 500 + C Eq. 1
1500 BBl = + A * sqrt (1000) - B * 1000 + C Eq. 2
900 BBl = + A * sqrt (2000) - B * 2000 + C Eq. 3
From the three equation calculate the constant ( A,B,C )
and substitued in the general equation so we can predict the flow rate by assuming any a mount of injection gas and draw a graph injection gas Vs flow rate for individual gas lift wells.
My quesion is : Lift gas response curve equation used by some production company for their oil fields to optimize gas lift wells using the procedure which I mentioned
Please if any person that he knows how to integral this equation or any information related to this equation help me it's very interesting for me to have sufficent information about this equation.
Best regards
