Abstract
Observed reservoir compaction as a result of fluid withdrawal can be different from that predicted from core measurements. Possible reasons are: i) there is large uncertainty or systematic errors in the field data; ii) the laboratory test procedures are not adequate for simulation of in situ conditions; iii) core samples are not representative of the field material. This paper provides a systematic attempt to quantify the importance of the latter point, i.e. the fact that a core sample when drilled free from the surrounding formations is stress released in a way which may cause permanent core damage (Holt et al., 1994).
