Conventional coring is a method of drilling and acquiring rock samples. To retrieve the core samples, the complete rod string and core barrel assembly has to be removed from the hole. Conventional coring is much more time consuming than wireline coring, as each rod has to be removed from the hole individually, then lowered back into the hole to continue to advance the boring and collect the next core sample. Hole Products offers conventional coring systems in DCDMA sizes B, N, H, and P. Optional triple tube designs are available to enable core recovery when drilling in soft or highly fractured formations.
