    Tubing and casing were sized so the tubing cross-sectional area and the
    annular cross-sectional area are nearly equal, isolating the effect of
    flow path geometry (circular vs annular) on friction:

        Tubing: 4.5" OD, 0.50" wall -> ID=3.50", area=9.62 in2
        Annulus: 6.25" OD casing, 0.30" wall -> ann area=9.17 in2 (ratio 1.05)

    Expected: with similar areas, reverse circulation (production up tubing)
    would have slightly less oil than forward (production up annulus) because
    the tubing imposes more friction on the multiphase production stream.

    Actual: reverse produced significantly more oil (217 vs 143 bopd). Likely
    caused by Beggs & Brill performing poorly in annular geometry — the
    hydraulic diameter correction for an annulus may overpredict friction.
    Test asserts the two directions produce different results, without
    asserting which is higher, until the annular multiphase model is better
    understood.
