The advantage of wireline coring over traditional coring lies mainly in the fact that the inner tube containing the sample can be retrieved (with the retrieval clamps / Overshot and a specific wireline winch) without having to pull up all the rods. This offers considerable and increasing time savings depending on the depth. As the equipment is more expensive, drilling companies generally consider that this method becomes profitable from a depth of about 50 metres. It is therefore the basic equipment for mineral exploration and deep geotechnical projects.
Another special feature is that each Wireline Core Drill must be used with its own associated drill string. In contrast to conventional corers, it is therefore not possible to use different rods for the same corer. The H WL corer can only be used with H WL rods, the P WL corer with P WL rods, etc.
Wireline corers are standard double corers, they can be converted to triple corers by exchanging the stop ring, extractor, extractor holder and crown. The sample is collected in a plastic sheath (to avoid handling the sample) or in a split half-shell tube (to be placed in a core box), either of which is placed inside the corer.
