An operator of a well service rig can retrieve and monitor a display of
data on the position of a block during rod and tubing insertion and
removal. The operator inputs into the system a minimum and maximum height
range that he wants the block to operate within. Data is provided to the
operator, in real-time, on a charted display relative to the maximum and
minimum position input by the operator to assist the operator in
evaluating the position of the block prior to a crown-out or floor-out.
In addition methods are provided for evaluating the activities conducted
by a rig based on evaluation of the block position data in order to
supervise a rig operation from an off-site site location. Furthermore,
the technology allows the operator or supervisor to determine the speed
of the block during operations by evaluating encoder velocity data
provided by an encoder velocity chart.
