PERFORM

Well PERFORMance Analysis , PERFORM is a graphical tool used for the analysis of single production/injection, oil/gas, onshore/offshore wells. Each of the well components is modeled using equations, correlations or mechanistic models to determine the pressure loss as a function of flow rate. The program is based on nodal analysis techniques that can increase production through an improved understanding of a reservoir's potential and an optimized well design and operation. PERFORM can be used for a lot of different tasks in both new and existing wells.

· Sizing of tubing and flowlines

· Sizing of coiled tubing and restrictions

· Designing offshore wells and flowlines

· Design of completions (perforations, gravel pack)

· Design of multilateral completions

· Modeling injection of water and gas

· Selection of separator pressure or compressor/pump horsepower

For existing wells, PERFORM can be used for:

· Improve well performance

· Evaluate future changes (water cut, GLR, declining reservoir pressure)

· Estimate unknown reservoir parameters

· Optimize gaslift operations

· Evaluate stimulation effectiveness

· Flow assurance (hydrates and scales)

· Estimate total skin factor

· Fluid heat transfer

· Information about PVT data, flow patterns, production per layers, etc.

· Answer ‘what-if’ questions related to workover results.
