Text Box: TWBS
Thermal Wellbore Simulator

  Detailed 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.

Latest Release: V5

-     Steam Circulation Period, Reservoir Temperature can be estimated as function of time using internal heat conduction model,

-     Reservoir Pressure for Steam injection, circulation entered at a datum depth. The reservoir pressure at segment depth will be calculated using fluid gradient from datum depth.

-     Segment Data Table summary color coded by pipe.

-     Review results of Pipe segments color coded by pipe.

-     Improved well schematic for plugged segments.

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.

 

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
