Lift Curves (LC) = Tubing Performance Relation (TPR) = Vertical Lift Performance (VLP) = Vertical Flow Performance (VFP)
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).
