Avoiding parent-child friction seems unavoidable,especially in horizontal well pad infrastructure.To kick off field development parent wells are primarily drilled,completed and produced.But,once the adjacent child well is drilled,it enters a pressurized and stressed environment.The more infill wells that are drilled in a section often leads to a higher water,lower oil production ratio and,ultimately,results in a steep decline in EUR.The argument posed is whether or not this is the result of well spacing.
