High nitrogenous natural gas

Up to the present, two high nitrogen natural gas (HNNG) fields have been discovered in Poland. These are Cychry and Sulęcin fields, situated in the Polish Lowlands and characterized by nitrogen content over 90 %. HNNG is good quality raw material for production of liquid nitrogen but it is more often used for correcting nitrogen content to specification of natural gas pipelines of the domestic distribution network. However, its utility for the latter purpose is smaller than that of gas from the fields with a lower nitrogen content but not smaller than 70 %, which are not differentiated as a separate group of HNNG fields.

Accepted abbreviations:

  • B - for solid minerals - mine in building process, for fuels - prepared for exploitation or trial period of the exploitation
  • E - exploited
  • G - underground natural gas storage facilities
  • M - deposit crossed out of the annual report of mineral resources during analized period
  • P - deposit covered by preliminary exploration (in C2+D category, for fuels – in C category)
  • R - deposit covered by detailed exploration (in A+B+C1 category, for fuels – in A+B category)
  • Z - abandoned deposit
  • T - deposit exploited temporarily
  • K - change of the raw material in deposit
