§
Detailed Segment Modeling of the flow of fluids and
energy in the various tubing strings of a vertical or horizontal well.
§
Computes the Oil, Water, Gas and Steam Rates in the
tubing strings and inflow/outflow to the reservoir.
§
Displays the Steady State Pressure, Temperature and
Fluid Saturation Profiles in the pipe strings.
§
Multiple Choke or Venturi FCDs - Liner or Tubing
Deployed
§
Computes Null flow points due to convergent or
divergent flow automatically.

APPLICATION:
DESIGN OF WELLS
►
Steam Circulation
►
Steam Injection
►
Producer with fixed rate profile or variable rate f(DeltaP)
►
Investigate artificial lift such as gas lift or pumps.
►
Optimize Injection and Production Flow Distribution,
FCD placement.
►
Optimize Operating Rates, tubing lengths and sizing.
►
Downhole Steam Generation using Electric Heater
►
Multicomponent Solvent and Steam Injection
SPECIFICS
►
Enter PVT data for up to 7 components. Internal Steam
Tables.
►
Import a Well Deviation survey. Automatically
subdivide the well trajectory into segments of various lengths
►
Specify and enter up to 5 pipes of various lengths and
diameters, concentric or side by side.
►
Model reservoir boundary conditions. Change reservoir
properties permeability, pressure, temperature, saturation along the well
length.
►
Set the inflow rates of oil, gas, water at each
reservoir segment, or calculate the variable influx based on current reservoir
and pipe conditions. Offtake and injection points may be set at any segment and
offtake/injection pressures specified. Injection rates, steam quality,
injection temperature may be set.
►
For calibration, observed data versus measured depth
can be entered
