    The completion approach chosen was to cement the production casing by using primarily foamed cement with a density low enough that the fracture pressure in the well was not exceeded. The placement of cement is always a potentially problematic operation, and if it is unsuccessful it can leave channels or pathways for fluid movement outside the casing.
