Laser rock spallation is a rock removal process that utilizes laser induced thermal stress to fracture and cause a break through the rock by creating small fragments before melting of the rock. In this paper we investigated the effects of CO 2 laser irradiation on limestone of Iran Sarvak formation. Since the limestone included heavy and light oil, we studied the amount of laser beam absorption by this oils for determining thermal fractured during the laser drilling laboratory process. In order to characterize this limestone spectrophotometry (from UV to NIR), scanning electron microscopy (SEM) have been used.

“…The laser power intensity distribution before and after the plasma absorption is measured in almost 3% of whole damages above the workspace surface (figure-6) [7] [25]. The influence dependence of the absorption of CO 2 laser in rock sample and oil with various API degree has been studied (figure-8) [6]. The measured absorption coefficient shows that heavy oil that could absorb very well, are good and simple attenuators for CO 2 laser radiation.…”

The capability level of rotary as well as first generation drilling operation could not be matched for deeply drilling programs. To reach that deep, the increasing in drill string length could also cause an additional constraint on hydraulic performance. The operation of slim hole drilling has significant potential to reduce well costs. This cost might be savings are especially important with increased demand for reduced capital finance under current economic conditions in the Iranian oil and gas industry. This savings achievement could be caused by use of smaller drilling rigs, work over rigs, reduced casing size, reducing requirement for drilling consumables and other costs associated with hole size. Otherwise, using laser irradiation for drilling operation can save cost little more higher look like do not using casing and perforation in reservoir layer for slim hole which are drilled by high power laser systems. As the matter of fact, Cost savings achieved from slim hole drilling could be offset by inability to effectively transmit the weight to the bit, increased mechanical failures of drill pipes and tools and reduced the well bore instability effects in particular, in drilling operation at greater depths This paper investigates the effects of borehole parameters during laser drilling operations in the case of slim hole.

Laser drilling is capable of reducing drilling costs and time. In laser drilling, a high rate of penetration (ROP) can be achieved, and the hole is cased due to laser interaction once it is drilled. In addition, laser technology can substitute conventional perforation techniques with no formation damage. Rock cutting with a laser beam is affected by various variables that fall within three categories; the rock parameters, purging system and experimental setup, and laser parameters. Each set of these categories affects the rock lasing process. Formation parameters include rock type, sample size, orientation, and the type of fluids saturating the rock sample. The purging system parameters include the type of purging system, application parameters, and the purging medium. Laser parameters involve laser type, laser application mode, beam power, duration, intensity, and frequency.This paper reviews several experimental works performed by institutes, researchers, and entities to provide the reader with a comprehensive knowledge base for further experimental work, modeling for laser drilling, and studies. Because performed laser drilling experimental work is huge and covers tremendous aspects, only the purging system and effect of formation parameters were considered in this review, while laser parameters will be presented in a later paper. Results showed that the laser can drill swiftly through all rock types in conventional vertical, directional, or horizontal drilling. For optimum laser drilling, the purging system and its parameters must be carefully chosen, including the type of system, purging gas, gas pressure, distance to the lased sample surface, and the purging angle. The optimum purging system uses nitrogen as a purging fluid.
