The âPerc Testâ. A Perc Test (also known as âPerk Testâ, and more formally known as a Percolation Test), is a soil evaluation that tests the rate at which water drains through soil.
Core samples are small portions of a formation taken from an existing well and used for geologic analysis. The sample is analyzed to determine porosity, permeability, fluid content, geologic age, and probable productivity of oil from the site. Drilling is the only way to be sure that oil and gas fields exist and exactly what is present in the formation. Core samples reveal the physical and chemical nature of the rock. In this activity, you will create a model formation and âdrillâ for samples.
