Lead Deposits in Dutch Natural Gas Systems

SPE Production & Facilities, 2001
Summary During the production of natural gas from Dutch Rotliegend and Kupferschiefer sediments that are next to "conventional" carbonate and sulphate scales, lead deposits sometimes also form. These deposits, which vary in composition from galena (lead sulphide) to elemental (metallic) to lead and complex lead (hydr)oxides, may form a ...

Modelling of sulphur deposition in natural gas

2005
The appearance of a solid deposit of sulphur, in the gas pressure regulation stations of the regional gas supplier Gaz du Sud-Ouest (GSO) leads to an increase in maintenance and costs. Several hypotheses have been made as to why the sulphur deposit appears. To study this phenomenon, we have modelled gas expansion by using a Flash.

Resource Potential of Natural Gas Hydrate Deposits Offshore Trinidad

SPETT 2012 Energy Conference and Exhibition, 2012
Abstract Seismic data and gravity cores indicate that natural gas hydrate deposits are present in the Columbus Basin off the East Coast of Trinidad. These data led to the initiation of a research program aimed at delineating and characterizing this unconventional resource. Already the areal extents of deposits in two offshore blocks have

Coalification and natural gas deposits in northwestern Germany

Geological Society, London, Special Publications, 1986
Summary In northwestern Germany most natural gas deposits have been sourced by coalification gases derived from the coal-bearing Upper Carboniferous. This is the reason why a new coalification map for the top surface of the Carboniferous (1:500 000) is presented as a supplement and revision of a former map published in 1979 by the same ...
