Chapter 2: General Information
Auxiliary Intermediate Well
What You Should Know
In all the power sweeps, the well which is immediately next to the center well is the auxiliary intermediate
well. There will be a need to use the auxiliary intermediate well if the center well is plugged or if there is
any difficulties in opening the center well during the gravity unloading process.
1. The auxiliary intermediate well (61) is the intermediate well closest to the center well (53) and will be
operated by the smaller diameter control rod.
2. The auxiliary well control rod (81) is assembled as rod-in-rod with the larger diameter intermediate
well control rod (75) and can be connected to the rack and pinion assembly (77) tube by placing a
5/16" x 1-1/2" HHCS bolt (17) through the rack and pinion assembly (77) tube to the auxiliary well
control rod (81).
NOTE: During gravity unloading, if the center well (53) is plugged, the auxiliary intermediate well
gate (116) must be opened independently from the rest of the intermediate well gates (70).
Make sure to remove the 5/16" x 1-3/8" safety pin (80) to open the auxiliary well gate (116)
alone.
