Also called  Lift Curves (LC) = Tubing Performance Relation (TPR) = Vertical Lift Performance (VLP).


Represents the relation between the bottom-hole pressure  p_{wf}  and surface flow rate   q  during the stabilised wellbore flow under a constant Tubing Head Pressure (THP)  p_s:

(1) p_{wf} = p_{wf}(q)

  which also depends on GOR and Yw.

The example of Lift Curves (LC) for single-phase fluid flow is shown on Fig. 1.1 (low-compressible) and Fig. 1.2 (high compressible).

The example of Lift Curves (LC) for dual-phase fluid flow shown on Fig. 2.


The examples of Lift Curves (LC) for  3-phase Oil + Gas + Water flow at various watercuts ( Y_w = \{ 20 \%, \, 50 \%, \, 80 \% \}) are shown on Fig. 3.
