Reverse Circulation (RC) RC is a quicker and less expensive form of drilling which produces small centimetre-millimetre-sized rock chips.Ground truthing of geophysical survey results is essential to providing a more accurate depiction of the subsurface geology of a property. Whether one uses direct (e.g., drilling or excavations) or indirect (e.g., remote sensing and geophysical methods) methods, bedrock mapping presents a challenge. Without a doubt, confirming that the top of ...WHEN TO USE CORE DRILLING. Coring is the technology to use when your project requires clear definition of geologic formations. While other drilling technologies can produce data about the subsurface, some of them—such as mud rotary, for example—could potentially miss a thin 3-inch layer.
