The Patriot frac plug provides a means to isolate multiple zones during high pressure stimulation frac operations. The Patriot is a ball drop(flow thru) Frac Plug that allows from fluid to flow to above and below the isolation point until the ball is pumped down from the surface and seated on top of the composite frac plug. The operator can pressure up against the frac plug to achieve isolation. Due to the composition of the material, the plugs can be easily milled and circulated back to the surface.

Store the equipment in a cool, dry place out of the direct sunlight. Wrap the tool in bubble wrap or cardboard and tape it in place. It is recommended to store the tool in a wooden or metal crate if extended storage (five years maximum) is expected, to protect the tool from damage.
The best mill for milling a composite plug with jointed pipe is a blade-mill type. This type of mill will reduce the possibility of casing damage during mill-up of the composite plug. The proper bit size should be 92–95% of casing drift diameter. Drill collars for weight and centralization are recommended. A junk basket is recommended to prevent larger cuttings from settling on the plug while milling. Rotary speeds from 50–150 RPM are recommended.
These practices and techniques have been developed through testing and field runs with the goal of achieving the optimal technique. However, it should be noted that a variety of parameters could affect the milling out of a plug. The milling/drilling techniques can and should change to meet those changing conditions.
