Abstract:
1. A method of cementing a liner hanger system in a wellbore, comprising: 1) providing a liner hanger system in a wellbore, the liner hanger system comprising a float shoe, a setting tool comprising a liner wiper plug, and a landing collar; 2) cementing the liner hanger system into the wellbore by pumping cement through the liner hanger system; 3) dropping a pump down plug into the liner hanger system, and landing the pump down plug in the liner wiper plug; 4) disengaging the landed pump down plug and liner wiper plug assembly from the setting tool, wherein the plug assembly travels through a portion of the liner hanger system and lands on the landing collar forming pressure seal; 5) opening a bypass on the liner wiper plug and pumping displacing fluid through the opened bypass to clear cement located in a shoe track area between the landing collar and the float shoe, wherein opening the bypass assembly comprises 6) curing the cement around the liner hanger system while leaving the shoe track area at least partly of cement and an area outside of the shoe track area at least partially free of cement, thereby allowing at least some fluid communication from within the liner hanger system to the formation surrounding the wellbore.
