Testing of a new generation horizontal soil sampler

摘要: Sampling using horizontal directional drilling allows the collection of soil samples from suspected zones located beneath structures and other surface-subsurface obstacles. However, current sampling techniques are time consuming thus expensive. This paper describes design testing a new multiple-port sampler for directionally drilled boreholes. The device uses methodology to improve cost-effectiveness sample quality.Key words: drilling, wells, design, remediation, site characterization, sampling.
