Abstract
Methods of completing poorly consolidated subterranean formations bounded by one or more consolidated formations to prevent sand production from the poorly consolidated formations are provided. The methods basically comprise the steps of drilling a well bore into the consolidated boundary formation adjacent to the poorly consolidated formation, creating a propped fracture communicating with the well bore in the consolidated boundary formation which extends into the poorly consolidated formation and producing fluids from the poorly consolidated formation into the well bore by way of the propped fracture.
