Abstract

The collection system (10) for collecting drilling cuttings removed from drilling fluid returns during borehole drilling for the purpose of sampling. The collection system (10) has a conveyor means (21), a transfer (23), and a loading means (25). The loading means (25) is provided for sequentially positioning a plurality of sample collection containers (27), such as sample collection bags, at a collection zone (24) to receive discrete quantities of the drilling cuttings via the transfer (23) The sample collection bags may be supported in holders (29). The discrete quantities of the drilling cuttings provide representative samples to be stored individually in the sample collection containers (27). The loading means 25 comprises a carousel (33) adapted to support the sample collection containers (27) and index them sequentially into position at the collection zone (24). Once a filled sample collection bag moves away from the collection zone (24) upon indexing of the carousel (33), the filled sample collection bag can be removed from its holder (29) and replaced with an empty bag in readiness to be filled when next at the collection zone (24).
