Abstract:
The drilling industry is currently investigating different ways of decreasing costs through multitude ofenterprising. The stuck pipe is classified as one of the main difficulties because it happens regularly andleads to substantial loss of drilling time. It usually happens in high pressure wells and leads to enormousdelays and costs in Iran, every year. Even if distinctive techniques and procedures have been developed toreduce the probability of happening of this phenomenon and these have saved drilling industry millions ofdollars, they suffer from exclusive prognostication of this event. Many attempts have been made todetermine the reasons of stuck pipe and to outline operating practices that will minimize the incident of theproblems. In this paper, according to the potential drilling challenges in each drilling section, we presentedthe planed drilling fluid and the most efficient decisions to prevent stuck pipe in 23 , 16 , 12 ¼ and 8 ½ holes during the drilling of a well in the this field. Also the best lost circulation and stuck pipe strategies foreach drilling section are expressed.
