Abstract
Methods and systems for determining risk of pipe deformation in a hydraulic fracturing operation include receiving a plurality of parameters pertaining to the well operation from a plurality of wells, developing a relationship between the plurality of parameters and a risk of pipe deformation, receiving the plurality of parameters pertaining to the well operation from a predetermined well, and determining the risk of pipe deformation in the predetermined well based on the plurality of parameters. The method further includes taking corrective action to prevent the pipe from deformation, such as improving the cementing conditions of the casing, performing cement bond evaluation, choosing safe locations for hydraulic fracturing or skipping zones of high risk or managing around pipe deformation by deploying flow-through bridge plugs, or dissolvable bridge plugs, or any other type of isolation method that does not require well intervention to remove the barrier or altogether re-drill a new well.
