● The Circulating Cap ( swage )is an attachment to the casing that provides the ability to circulate fluids prior to the cementing operation.
● Hole conditioning is very important as it prepares the well for better displacement of the cement slurry, improved fluid movement, removal of residual gases in the drilling fluid, and
removal of any gelled drilling mud and formation filter cake which may be present after drilling is completed.
● The circulating fluid is transmitted from the pumper truck through the pump line and into the circulating cap ( swage) via the 2" Fig. 1502 inlet on top of the assembly.
● Remove the lift plug to attach the pump line.
● The bottom sub may be threaded with an API or Premium connection to attach to the casing string.
