WPA Workflow
The workflow is similar to other modules, with a
control panel guiding the engineer through the
default steps; defining the problem, input PVT,
define the well, calculate the VLP and the IPR and
run sensitivity analyses.
Defining the problem and PVT
The user defines the type of well, producer or
injector, the reference phase and the PVT is the same
standard black oil PVT used in other modules.
Defining the well
Wellbore and flow line can be treated independently
or together. Wellbore flow may be tubular or annular,
with trajectory, ID, roughness, detailed completion
with any number of restrictions included. A well
sketch uses a library of pre-defined completion
components.
Vertical Lift Profile (VLP)
Multiple pressure drop models may be defined
with one required as the reference. Each model
can be assigned factors to honor observed data. A
temperature profile must be loaded or calculated.
The built-in temperature model uses a segmented
model incorporating convection, conduction, and
thermal compressibility effects.
The VLP option generates traverses (p vs. depth)
and VLP plots (p vs. q). For each scenario user data
can be input manually, from a file, or picked from
production data. On validation, each scenario is run
and the corresponding plot built. The plot content
can be customized interactively.
