GEOLOG upgrades rigsite gas sampling tubes

Published by , Editor
Oilfield Technology,

GEOLOG has recently upgraded the design, manufacture and QA procedures for their rigsite gas sampling tubes. To align with this evolution, the improved gas sample container is being relaunched as the GeoTube.

The manufacturing quality assurance process has been fully revised, with a rigorous batch-testing procedure implemented to ensure that each tube is evacuated to a consistent level of vacuum for more reliable sampling. The shipping carton has been redesigned to ensure full compliance with IATA rules, allowing boxes of 48 filled tubes to be transported on standard passenger flights.

The tubes provide a highly cost-effective alternative to other gas-sampling containers available on the market, typically being less than 20% of the cost of the main competitor. This enables many more samples to be taken for the same cost, allowing much greater depth resolution in sampled gas. The tube is filled from a front mounted port fitted to every GEOLOG mudlogging gas distribution system; therefore, no additional equipment is required to take samples. Although the tubes are much more compact than alternative products, modern laboratory equipment requires only small volumes to carry out analysis: the volume contained within the tube being sufficient for multiple analyses to be performed. Compatibility of the design with advanced auto-loading technology allows the tubes to be quickly and efficiently analysed in the laboratory.

As GEOLOG increasingly performs advanced gas analysis studies in the GeoTech Laboratories, the GeoTube as a highly reliable and cost-effective method of taking samples at the rigsite for further laboratory analysis.
