T029 Borehole Breakouts and Sand Production in Porous Sandstone G. Dresen* (GFZ German Research Centre for Geosciences) & S. Stanchits (GFZ German Research Centre for Geosciences) SUMMARY 71 st EAGE Conference & Exhibition — Amsterdam The Netherlands 8 - 11 June 2009Introduction Borehole instability and sand production cause major problems in the operation of wells penetrating poorly consolidated and highly porous sandstones of hydrocarbon and geothermal reservoirs. Sand production from perforated casings or open hole sections poses a common problem in weak reservoir rocks and understanding the sanding mechanisms is important in optimizing well production. Localized damage around the wellbore
