Gas Lift Design & Optimization Using MS Excel
Description
Gas lift design is a sequence of calculations that suits a spreadsheet well: build the flowing gradient, find the deepest injection point available at the injection pressure, space the unloading valves so they open and close in order, size the ports and set the test rack pressures. Building this in Excel gives engineers a design tool they can check and adapt, and the ability to verify vendor designs.
The course builds the full design workbook and then extends it to optimisation. It starts with fluid properties and gradient calculations, then injection point determination, unloading design and valve spacing, port sizing and valve setting calculations for injection pressure and production pressure operated valves. It then builds gas lift performance curves, optimises injection rate for a single well, and extends to field-wide gas allocation under a compression constraint. The final part builds diagnostic tools: comparing measured gradient surveys against design, identifying multipointing and valve leaks, and screening wells for redesign.
The central gas lift calculation is straightforward: at every depth, compare the pressure available in the casing with the pressure in the tubing, and the injection point is where injection is possible. Everything else, including valve spacing, port sizing and setting pressures, follows from that comparison and from the requirement that each unloading valve closes once the next one starts injecting.
Optimisation is a separate calculation. For a single well, gas lift performance curves show the injection rate that maximises production and the point beyond which additional gas reduces it through friction. Across a field with limited compression, the optimum allocates gas to the wells with the steepest incremental response, which is a constrained optimisation problem that Solver handles well.
Diagnosis completes the picture. Comparing a measured flowing gradient survey against the design shows immediately whether the well is injecting where it should, whether more than one valve is passing gas and whether the operating valve has failed. Participants build that comparison as a working tool during the course.
By the end of this training, participants will be able to:
- Build fluid property and flowing gradient calculations for gas lift wells.
- Determine the deepest achievable injection point for a given injection pressure.
- Design unloading valve spacing and verify the unloading sequence.
- Calculate port sizes and test rack setting pressures for injection and production pressure operated valves.
- Build gas lift performance curves for a well.
- Optimise injection rate for a single well.
- Build field-wide gas allocation optimisation under compression constraints.
- Compare measured gradient surveys with design and diagnose deviations.
- Identify multipointing, valve leaks and insufficient injection pressure from data.
- Screen wells for gas lift redesign and quantify the expected gain.
