Abstract

The present invention provides a sampling apparatus (13) for use in extracting a sample from cuttings which are delivered to the sample apparatus (13) entrained in a gaseous stream. The apparatus (13) comprises a separation means to separate the cuttings from the gaseous stream and a sampling assembly (17) adapted to receive the cuttings from the separation means to allow samples to be taken therefrom. The separation means comprises a cyclone (11) to which the cuttings entrained in a gaseous stream is delivered. The cyclone (11) has an outlet (47) through which the cuttings pass from the cyclone, and a vent (27) through which the gaseous stream passes. The cyclone comprising an inner rotating body (33) wherein the body (33) is cleaned as it rotates.

Abstract

The present invention provides a splitter assembly (15) for distributing particulates, such as cuttings from a drill rig. The splitter assembly comprises an inlet (121) for receiving the particulates, a diverting chamber (119) into which the particulates are received, a distribution means (127) for distributing the particulates, and a sampling outlet (123) through which the cuttings are channeled to a sampling assembly (17) for taking a sample.

Abstract

The present invention provides a splitter assembly (15) and a sampling apparatus (13) which comprise the splitter assembly. The splitter assembly mixes particulates, such as cuttings from a drill rig. The splitter assembly comprises an inlet (121) for receiving the particulates and a mixing region (119) into which the particulates are received. The splitter assembly also comprises a mixing means for mixing the particulates, and a sampling outlet (123) from which a sample of the cuttings is channelled in an unbiased manner.
