One billion cubic metres (BCM) is equivalent to 35.31 cubic feet. This makes gas much more mobile in the reservoir than either oil or water. Here you take a model that consists of two plates one on top of the other. Under the same conditions a liquid with a low viscosity, such as water, will flow more quickly than a. More information Gas viscosity Just as the compressibility of natural gas is much greater than that of oil, water, or rock, the viscosity of natural gas is usually several orders of magnitude smaller than oil or water. Viscosity describes the condition of a liquid or gas. Molasses, for example, has a greater viscosity than water. Viscosity is the resistance to flow of a particular fluid. The reciprocal of the viscosity is called the fluidity, a measure of the ease of flow. Definition of viscosity (Newton’s law of fluid friction) Viscosity describes the internal resistance to flow of a fluid (internal friction). This resistance is a result of friction between the liquid undergoing deformation under shear stress and the solids and liquids present in the drilling mud. Viscosity, commonly depicted by the symbol, is a physical property of a fluid that describes its tendency/resistance to flow. Once the value of K is known, the viscosity can be determined by measuring the amount of time the test liquid flows between the two graduated marks. Means a billion cubic metres and is generally used to measure natural gas. viscosity, resistance of a fluid (liquid or gas) to a change in shape, or movement of neighbouring portions relative to one another. Where \(K\) is the value of a liquid with known viscosity and density such as water. The American Petroleum Institute gravity, or API gravity, is a measure of how heavy or light a petroleum liquid is compared to water: if its API gravity is.
