Abstract: Reports on tubular failure experienced during horizontal drilling of wells in the Middle East. The wells, drilled from land rigs and using drill pipe and heavy weight drill pipe are outlined experienced an abnormal amount of cracks. Investigations into the cause. These looked at well designs, particularly individual rig well programs, the planned build rates and the length of horizontal sections. Lubinski's modified equations were used in the fatigue analysis. Lubinski's modified equations can be used to predict drill pipe fatigue damage in horizontal and directional wells. To demonstrate the effectiveness of these equations, the investigations carried out at the drill pipe and heavy-weight drill pipe (HWDP) used by land rigs operating in the Middle East are discussed
