Software reference. Computer programs are not given for the constant area models in Cases (a), (b),
(c) and (d) since the solutions already appear analytically in closed form. For the variable area
problem, both solid and open drillbit reflector models are hosted in C:\MWD-00\TENEQ22-
SUBSET-3.FOR. Plots similar to those shown above are automatically produced by the Fortran
code. An interface does not exist. Parameters are changed by editing Fortran source code directly.
