Effects of laser drilling on rate of penetration for oil and gas wells drilling

Abstract

Need for bring a new method of drilling oil and gas wells is necessary. drilling industry was developed, since the rotary drilling superseded cable tools drilling. One of the great parameters that effect on drilling process is ROP. The term ROP contracted, Rate Of Penetration. This paper describes result of research about laser systems in drilling rock samples that give from Iran’s formations. Although studying widespread about laser drilling in the world but, so far in Iran not to be done main study about laser drilling systems. The samples of stone which were experimented in this paper were took from various formation of Iran’s. the result were encouraging that ROP increase of 10 to 100 time faster by using with laser drilling to rocks penetrate. In this experiment we encountered with limited facilities, so laser system that using in this research have low power. However by using this power obtained precision result. Testing conducted with Free-Electron Laser (FEL) system that speed setup in 10mm/s with spiral drilling operation.Need for bring a new method of drilling oil and gas wells is necessary. drilling industry was developed, since the rotary drilling superseded cable tools drilling.
