An Introduction to Optimize IT Gas Lift Optimization

The Gas Lift Optimization software package will, based upon the available gas-lift rates and the given inputs, optimally distribute the gas lift rates to the wells.


In general, the optimization is divided into a 2-stage process:
1. Generation of gas lift performance curves using the Production metering software, (see previous page) or manual input.
2. Calculation of optimum gas lift distribution



The operator/engineer needs to provide the software with following input:
- Available gas-lift rate
- Choke positions
- Verification of process I/O values

The output includes:
- Recommended optimal lift gas distribution between the gas-lifted wells, with respect to maximum oil production
- Gas, oil and water production from each well and in total

The Gas Lift Optimizer will seek to increase the gas injection rate to the well with the highest ratio between increased (or decreased) oil production rate to increase in gas-lift rate, i.e. d/Qoil)/(dQgl). Based upon the available gas-lift rates and the given inputs, the Gas Lift Optimizer will optimally distribute the gas lift rates to the wells. The optimum point is found when d/Qoil)/(dQgl) is the same for all wells.
Optimal gas lift distributions between the gas lifted wells and other output results are presented for the operator through the GUI. In turn, the results can easily be exported to standard software like Excel for reporting.

Running on a Windows® 2000 or XP PC, and utilizing the most common industry standards for program implementation and communication, the Gas Lift Optimization software can easily be integrated with any kind of production control system. The information provided by the Gas Lift Optimization tool can be transferred to the production control system database, and may be sent to a remote operations center for closer analysis.
