5 ResultsThis chapter is structured as follows:• Section 5.1 – an overview of the drilling progress of KFM06C.• Section 5.2 – geometrical data and technical design of KFM06C.• Section 5.3 – results from percussion drilling of KFM06C.• Section 5.4 – results from core drilling of KFM06C.Well Cad-plots are composite diagrams presenting the most important technical and geoscientificresults from drilling and investigations made during and immediately after drilling. WellCad-presentations of borehole KFM06C are shown in:• Appendix A (percussion drilled part of KFM06C).• Appendix B (the complete KFM06C).• Appendix C (absolute pressure, borehole section 351.0–636.0 m).5.1 Drilling progress KFM06CDrilling of borehole KFM06C was carried out during two periods, between March 9 th 2005and April 13 th 2005 (percussion drilling) respectively April 27 th 2005 to June 29 th 2005 (coredrilling), see Figure 5-1.5.1.1 Percussion drilling periodPercussion drilling is normally a rapid drilling method compared to core drilling. However,the relatively complex approach applied for the drilling, and especially the grouting sequenceswhen drilling KFM06C, resulted in a rather long total working period.The durations of the different operations of the percussion drilling from 2005-03-09 to2005‐04‐13 are presented in Figure 5-2.KFM06C 2004 2005March April May June July AugustPercussion drilling KFM06CInstallation of core drilling equipemen KFM06CCore drilling KFM06CFigure 5-1.
