Continuous gas lift system is a common artificial lift method employed by many oil companies to start up a well or to increase the production rate of the well. The concept aims at lowering the hydrostatic pressure inside the tubing through injection of lighter fluids into the annulus.The drop-in production brought about the implementation of the continuous gas lift system, which is aimed at maximizing production at an optimum economic gas rate. Furthermore, still on maximizing production, the valve port sizes where adjusted to observe the effect it has on the production. For the course of this work, prosper simulation software is used for matching data, model creation, designing the gas lift system and the adjustment of valve-type port size. After implementing the continuous gas lift system, the result gave an optimum production rate of 2666.6stb/day at a gas injection rate of 13MMscf/day with unloading depth 3526.13ft and operating valve depth 8389.29ft for well A03 at 60% water cut and the optimum production rate of 2756.55stb/day for well A04 at an injection rate of 7MMscf/day at 50% water cut at an unloading depth 3530.41ft and operating valve depth 6929.45ft. With the two wells running under the valve- type Camco R-20 normal or Valve type RP-60 Camco Normal.
