Gas Effect on Compressional Slowness 

Gas Effect on Compressional Slowness
Description: This chart illustrates the effect that gas in the formation has on the slowness time of sound from the sonic tool to anticipate the slowness of a formation that contains gas and liquid. Enter the chart with the compressional slowness time (Δtc) from the sonic log on the y-axis and the liquid saturation of the formation on the x-axis. The curves are used to determine the gas effect on the basis of which correlation (Wood’s law or Power law) is applied. The slowing effect begins sooner for the Power law correlation. The Wood’s law correlation slightly increases Δtc values as the formation liquid saturation increases whereas the Power law correlation decreases Δtc values from about 20% liquid saturation.
