“Early & Accurate Quantification of Mercury Contaminant Levels in Gas-Condensate Reservoirs”.
John Babadimas (Woodside Energy)

Abstract:
Mercury is a trace contaminant present in natural gas and condensates. Production facilities must be designed to remove anticipated mercury contamination in natural gas streams to meet process safety, health, environmental, regulatory and sales requirements. Early and accurate quantification of mercury concentration levels is therefore critical for the safe and economic development of gas resources. This presentation introduces reservoir fluid sampling and mercury analysis techniques demonstrated to accurately determine the mercury concentrations in gas-condensate reservoirs.
By implementing a combination of procedural changes, sampling tool modifications and improved measurement techniques, it is possible to acquire reservoir fluid samples with formation sampling tools and accurately measure mercury concentrations representative of that produced from the reservoir.
The case study of a gas-condensate field is used to demonstrate that by following novel techniques, reservoir fluid samples acquired from wells using formation sampling tools and analysed for mercury can accurately represent the mercury concentration levels measured later during the production phase. Processing facilities can then be appropriately designed or modified early in the field development lifecycle to remove any anticipated mercury in natural gas process streams.
