As time goes by, increase in world’s energy demand forced oil and gas companies to drill deeper in order to produce more oil and gas for balancing world`s offer and demand. Non Productive Time (NPT) is the main cause of delays in drilling projects . There are numerous occurrences or eventualities that cause stoppage of drilling operations or marginal reduction in advancement of the drilling progress leading to Non Productive Time (NPT). For any industry cost and time related to production and quality management or wastages reductions have important impact on overall expenditure. Emphasizing on it steps have been taken to investigate and eliminate wastages, that is, non -productive time in drilling rig in order to save time and cost and lessen down time. The focus of the present work is on the causes which are the reasons for down time and will to find out the key cause which causes the down time most of time. An industry may gain higher productivity and profitability by eliminating non-productive activities. In this work data were collected from eighteen rigs and analysis were done to find out the root causes of non-productive time in rig operations by Pareto analysis.
