What you should know about drill cuttings

Using drill cuttings is a choice of quantity over quality. It is highly unlikely that you will ever get a perfect representative sample, but drill cuttings provide you with an abundance of representation and availability. A good analogy for drill cuttings is to think of a road map and imagine what the world was like before Google Maps.
