Whether you want to try borehole image log interpretation yourself or just want to find out more about what information borehole image logs can contain then this section is for you.

OVERVIEW OF BOREHOLE IMAGING

Lai, J., Wang, G., Wang, S., Cao, J., Li, M., Pang, X., Han, C., Fan, X., Yang, L., He, Z. and Qin, Z., (2018). A review on the applications of image logs in structural analysis and sedimentary characterization. Marine and Petroleum Geology, 95, 139-166.

Comprehensive and up to date review paper including information on imaging tools, processing workflows, core orientation, image facies (with examples), fracture identification and classification, in-situ stress, structural analysis of dip data, and palaeocurrent analysis. Good reference list.

Pöppelreiter, C., García-Carballido, and Kraaijveld, M., (2010). Dipmeter and borehole image technology: AAPG Memoir 92.

A good, fairly recent, introduction to image logs covering all things from image data QC and processing to structural and sedimentological interpretation. Includes some nice case studies of fluvial and deep-water deposits.
