It is commonly known that when an oil well is first completed, the natural reservoir energy causes the fluid to flow to the surface for some period of time. However, most oil wells, at some point during their economic life, require artificial lift in order to increase the reservoir energy needed to raise fluid to the surface and obtain the maximum recovery of oil for maximum profit to the producer well. Artificial lift systems include rod pumping, gas lifting, hydraulic pumping, and centrifugal pumping. Continuous gas lift is the most commonly used artificial lift system in the oil industry. It is inherently a high volume method and the only one which makes use of the reservoir gas energy.
This paper discusses the use of a multiphase flow meter to optimize gas lift field operations. In particular, it will compare analysis methods for individual well’s performance using Multiphase Flow Meter versus Standard Nodal Analysis. This paper will also tackle GUPCO’s field experience of gas lift offshore operations.
