Abstract
Methods of completing poorly consolidated, weak, or otherwise unstable subterranean formations bounded by one or more consolidated formations to prevent well bore stability problems and/or sand production from the poorly consolidated or unstable formations are provided. The methods basically comprise the steps of drilling a well bore into the consolidated boundary formation adjacent to the poorly consolidated or unstable formation, creating at least one flow channel communicating with the well bore in the consolidated boundary formation which extends into the poorly consolidated or unstable formation and producing fluids from the poorly consolidated or unstable formation into the well bore by way of the flow channel.
