STAGE SEPARATIONMULTI FLOWING TUBING PRESSURE (FTP)
• Maximize use of reservoir energy as long as does not affect production rate.
• Keep each well in as high pressure system as possible for as long as possible.
• Manifold individual well flowlines to each stage to allow each well production to be routed individually without interfering with others.
