The emerging nanoscience, nanotechnology and nanomaterials can be used for various industrial applications to enhance reliability, performance, stability and functional capability. Their application in the design and development of tools and materials used in oil and gas industry for extreme drilling conditions could overcome the current limitations of conventional tools and the various fluid systems used by the industry. The functional limitations such as poor physio-chemical stability in acid gas environment, frequent mechanical failure and malfunctioning in complex geological environment, thermal degradation in high temperature environment, etc. of currently used conventional tools and fluid systems are associated with extreme operating conditions due to a shift of the drilling operation from low risk to high risk geological environments, onshore to offshore locations, shallow water to deep water environment, etc. The progressive shift to increasingly higher risk operating environments is unavoidable as the energy demand of global community has increased manifold and is expected to increase further in future. Moreover, the probability and likelihood of finding easy oils and gas resources in low risk areas are diminishing quickly. That is why the oil and gas companies are constantly shifting to extremely challenging environments to meet the global energy demand. This is reflected by the expansion of drilling activities in complex geological areas, deep water environments, extreme-HPHT environments, etc. As the current tools and equipment and also the additives and chemicals often fail and/or lose their functional ability due to the detrimental effect of exposure of extremely harsh conditions, the industry needs tools and equipment, chemicals fluid additives that are highly reliable, chemically resistive, thermally and mechanically stable to ensure safe and trouble free drilling operations. It has been demonstrated in several fields of study that nanostructured materials and additives exhibit improved mechanical, chemical, thermal, electrical and tribological properties that can significantly increase the stability and durability of the tools and equipment along with the chemical and thermal stability of additives required for high performance fluid design. This review article captures the recent developments about the application of nanomaterials in the design and development of tools, equipment, additives, chemicals and smart materials to overcome current and future technical challenges of the oil and gas industry. Finally, the conventional of rule of mixtures of composite materials design and the current nanotechnology-based research conducted by various researchers have been highlighted to demonstrate potential of nanotechnology to enhance the physical, mechanical, chemical and thermal property of tools, equipment and various fluid systems used by the oil and gas industry.

“…Drilling horizontal well with gas recently has been considered as an innovative technique for tight gas sandstone reservoir and shale gas reservoir development. It can increase footage capacity by nearly 60% (Ford et al, 2011) and reduce drilling cost. However, unlike conventional mud drilling, gas drilling can't improve hole cleaning efficiency by optimizing the drilling fluid's rheological properties.…”

Given the downturn of natural-gas prices in North America, it is vitally important to reduce the cost of drilling shale-gas wells. Gas-percussion drilling with nitrogen gas recently has been used in shale-gas field development. It has increased footage capacity by approximately 60%. Because the rate of penetration (ROP) is fast in gas-percussion drilling, it requires injection of an adequate quantity of nitrogen gas to clean the hole. However, a high rate of gas injection often causes wellbore erosion and deviation problems. It is imperative to determine the optimal range of the nitrogen-gasinjection rate that can mitigate the problem.This paper presents an analytical method for predicting the optimal range of the nitrogen-gas-injection rate required to balance the borehole-cleaning and -integrity issues. The optimal gas-injection rate was sought between the minimal value required for hole cleaning and the maximal permissible value to avoid hole erosion. The minimal value was determined on the basis of Angel's kinetic-energy theory for cuttings removal modified with Charles' theory of particle-grinding energy. The maximum required value was estimated by use of the sonic flow criterion at the bit. Good consistency was observed between the predicted optimal range of gas-injection rate and field problem-free nitrogen-gas-injection rates. This paper provides drilling engineers a practical tool for designing the optimal range of nitrogen-gas-injection rate to cut shale-gas drilling cost.
