| Definitionskos:definition | Core drilling using a diamond or tungsten carbide bit and a core barrel with fibreglass inner sleeves. 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. Used in the oil industry. |
