Sammendrag
Well instability in shale formations has been a very major problem due to physiochemical interactions between drilling fluid and formation. In this thesis, chemical, thermal and diffusion effects on the well collapse strength are evaluated in order to investigate the dominating driving forces. A case study on the designed Heidrun well program was also performed in order to study the dynamics of the collapse pressure during drilling phase due to various driving forces.
