NQ3 UNDERGROUND WIRELINE DOUBLE TUBE CORE BARREL ASSEMBLY
Despite its many benefits, the double tube core barrel does have some limitations. It is not well-suited for drilling in areas with high water content or loose soil, as these conditions can cause the sample to become contaminated or lost. Additionally, it can be more expensive and time-consuming to use than other drilling methods.
