Gas lift pipesim correlations1/2/2023 ![]() This method is more accurate than the horsepower conversion method because the pump efficiency is a function of the capacity but is iterative. The pump curve method requires that the user supply a pump curve for a specific pump to the model and the software iteratively determines the pressure boost and temperature change for the prevailing well conditions. Pump Curve method (a pump curve is a series of curves including the pump head (pressure boost) versus capacity (flow rate), power input (horse power) versus capacity, and pump efficiency versus capacity – all plotted on the same graph). ![]() There are two ways to generate the tubing performance curves for ESP wells/completions: Current generation well hydraulics software has options for all common downhole devices including (but not limited to) downhole pumps, gas lift valves, chokes, sub-surface safety valves (SSSV), gravel packs, perforations, etc.Ī well completion with a downhole ESP device is shown in Figure 7.24. A downhole device is a piece of oilfield equipment with known rate pressure-rate behavior. ![]() This is done by adding Downhole Devices into our well model. To perform the analyses, a segmented well hydraulics model (discussed in Lesson 6) must be designed to generate the appropriate tubing performance curves for use in the analysis. The design of ESPs and gas lift systems can also be considered in the IPR-TPC analysis. We will only discuss two methods of artificial: ESPs and gas lift.
