Helium reserves or resources-what's the difference?

摘要

In recent years,due to recurring shortages of helium and its increased commercial value,there has been an unprecedented amount of activity related to exploration for new helium sources.There are currently 10-20 companies actively involved in helium exploration,including a handful that are publicly traded.Some of these companies are issuing frequent press releases,as they look to raise money to fund their project.It is difficult for a potential investor or business partner to evaluate these opportunities without a general understanding of reserve and resource nomenclature.When it comes to the chances of commerciality and risk of recovery,there is a lot of difference between reserves and resources.This article for gasworld will discuss the meanings and differences between'Reserves','Contingent Resources',and'Prospective Resources'(a table later in this article lists criteria comparing the various types of resources).
