The graph of Maximum Set-Down Weight vs Depth tells you how much push, if any, you can apply at the end of the toolstring at each depth. This is the same as Maximum Weight On Bit (WOB), an extremely important parameter in drilling operations. Note that Cerberus is able to predict WOB with considerable accuracy given only surface weight and depth, and without the need for downhole MWD type measurements, a feature which is exploited in the real-time mode.

Since cable is unable to support compression (you can't push a rope), this result is less useful in wireline mode. However, there are some situations where it can still come in handy, especially when there is a heavy toolstring used to shift a sliding sleeve or set a gas-lift mandrel in a moderately deviated well.

Note that the results are negative. This is the sign convention used in Cerberus, where upward force (tension) is positive and downward force (compression) is negative.
