Determination of in-situ stress parameters from measurements on cores
The minifrac technique has been extensively used to measure the vertical distribution of the minimum horizontal in-situ stress. However, its implementation is often hindered by technical and economic considerations. Consequently, the determination of the stress field on the basis of laboratory measurements of orientated core samples is investigated. New developments and the results of three methods are presented: anelastic strain recovery (ASR), differential strain curve analysis (DSCA), core discing analysis. The results obtained using these methods on cores extracted from several wells are described and discussed. A comparison is made with data available from minifracs, logs and regional tectonics.
