The Utilization Of Underbalanced Drilling Technology May Minimize Tight Gas Reservoir Formation Damage: A Review Study

Abstract — as many oil & gas reservoirs are depleting every day around worldwide, the demand for fossil fuel has been dramatic. Therefore, the international oil & gas companies & operators are trying to find out new hydrocarbons energy sources for instance, heavy oil and tight sand gas. Nowadays, tight gas reservoirs are one of the most attractive new energy sources for oil & gas companies and researchers as well. Tight gas reservoir refers to hydrocarbons reservoir that content unconventional gas. Tight gas reservoir usually possesses low permeability rocks that make the gas tricky and difficult to produce (Noeth, 2004). Tight gas reservoirs are distributed in many part of the world for example, Australia, Asia and North America. However, the largest accumulations of it are in two major regions, North America and Russia. Tight gas formation is usually damaged due to its low permeable rocks. In fact, hydrocarbons formation damage is a
