Casing Drilling is an emerging technology for drilling and casing a well simultaneously. Using this technology, the casing is used to transmit mechanical and hydraulic energy to the bit, instead of using a conventional drill-string. The problem which really has to be solved is the evaluation and optimization of the well hydraulic in relation with casing drilling. Developing drilling mud technology follows the industrial needs but in the interest of reducing formation damage, the objective is choosing the most suitable drilling mud. This study aims at providing new information/data for improved hydraulics and the support of drilling mud selection when drilling into unusual depths and formation structures, particularly at high temperature high pressure (HTHP) conditions.
