👉 Oil tightness is a property that describes how well an oil reservoir can resist the flow of fluids. It refers to the ability of the oil to resist the movement of liquids, such as gas or water, through the borehole or well. In drilling and production, the concept of oil tightness is important because it helps in determining whether a well is capable of producing oil or other valuable products from a reservoir. The higher the oil tightness, the more likely it is that the reservoir will be
