Fig. 27From: Laser drilling: reviewing the effect of purging system and formation parametersThe effect of saturation fluid on granite and limestone sample lasing process for dry (orange), water (yellow), and heavy oil (gray) saturated samples. A and B shows the created hole depth variation with lasing, C and D shows the SE value variation with beam duration, and E and F shows the ROP recorded for the lased samples [75]Back to article page
