The 6in. hole was drilled over 660m in depth of 4, 400m in Niigata prefecture by Teikoku Oil Company. In high pressure and high temperature formation, strength of drill strings and fishing tools were considered carefully. Field investigation of DC's total revolution and magnetic particle test were carried out carefully. No DC failure was resulted due to these inspections.<br>In some previous wells, DC failures occurred in many times. After that, magnetic particle test was decided to carry out regularly in order to prevent DC failures. No DC failures have occurred in the wells of Teikoku Oil Company after this magnetic particle test was introduced.Even though magnetic particle test was carried out by the skilled person in the first stage, currently this method is done by the drilling crews as routine work.<br>Even though data about bit selection and bit life are not enough, results of actual experience, 50 hours bit life for tri-cone insert bit and 132m/135.5hrs bit performance for impregnated bit with down hole motor were attained.<br>In this paper, field experience of slim hole drilling method in HPHT and several technical issues, which played the important role, are reported.
