Experience suggests that enough time also needs to have elapsed since the broken-out section of the well was drilled for these fractures to propagate, coalesce and give rise to spalling. Probably, drill-pipe abrasion during drilling also assists the development of breakouts. Judging by the prevalence of breakouts in oil and gas wells, these requirements are frequently met by shales and often by sandstones. Many limestones also exhibit breakouts and they have even been recorded in salt.
