A New Correlation for Calculating Wellhead Production Considering Influences of Temperature, GOR, and Water-Cut for Artificially Lifted Wells

Several classical wellhead production correlations have been<br>developed and widely used all over the world for naturally<br>flowing wells. For artificially flowing wells, many important<br>well and fluid parameters are ignored in these correlations.<br>This results in erroneous results and inaccurate predictions<br>when these correlations are applied. These current correlations<br>are mainly function of tubing head pressure, bean size (which<br>has almost no effect for artificially flowing wells), and gasliquid<br>ratio only.
