Due to constructive role of technology developments in petroleum industry and their affects in reducing the costs of drilling, it is necessary to use future technologies. One of these new progresses taking very effective role in drilling industry is to get use of laser in drilling processes. The aim of this paper is to categorize and represent the different study results and also to analysis the principle and advantages of laser drilling. Compared to prevalent drilling, laser drilling is capable to augment the efficiency of drilling and solve its problems such as increasing the rate of penetration, monitoring the bottom hole, diminishing equipment and drilling process, but faces some problems such as laser beam transference, cleaning the down hole. As a result, the benefits of laser drilling overcome the problems and it can be replaced or combined in bits in early future. in this paper we showed the result of using laser technology during drilling operation. Also, In this paper we experiments on changing wavelength transmitted during fracturing and drilling.
