Greetings !
underbalance= FP > ECD > BP : geomechanics stated that due this, we need less pressure (hydraulic and mechanic), less WOB (in comparisson with overbalance conditions in the same environment) to break the rocks. Its a wide subject but this is the main idea...i suggest you to read any paper related to underbalance principles.......anyway, i will check if i have any file to share with u....
regards
