Non Productive Time Teduction as an Effective Parameter on Environmental Damages

As time goes by, increase in world energy demand forced oil and gas companies to drill deeper in order to produce more oil and gas for quenching the thirst of human needs. This requires drilling layers with various lithologies with variable characteristics and dealing with more drilling problems as going deeper. In this regard the most important point is to reduce cost, environmental damage and increase safety. There for serious consideration for reduction of non-productive time (Non-productive time is defined as time which drilling is ceased or penetration rate is very low) is a high importance issue. In this paper by determining exact mud weight window it would be attempted some drilling problems such as lost of circulation and stuck pipe which can lead to increase of drilling cost and damage of environment reduced or prevented.
