Oil well drilling operation is the subject of many activities, and for each part of its works and activities there is a particular tender for time schedule, quality and cost. I want to go back over an event which began in 2009 and finished 15 months later after continuous operation; the Bazian exploration oil well, Bn-1. As far as I am concerned, the most important point that I want to convey is the relation between the three main points above, giving attention to these aspects and asking some questions in this regard, which will be easy for me to answer because I was working there and I was a part of those operations. New technology, a professional team, logistic support, security, skilled staff and team work were all main elements hidden within the above-mentioned main activities.

The aforementioned uses only a normal running of casing pipes, and these operations will normally take one day, but in the Bazian Bn-1 exploration oil well the time taken was more than one month. In this paper I want to make a very quick review of most of the operations performed for running 9-5/8” casing for the interval from 1195m to 2028m, which will clearly show that after three attempts we were not able to run the casing 100% as planned, and I will provide a technical recommendation for future operations in a similar situation.
