Drill-Bit Metamorphism Generates Artificial Hydrogen: A Challenge for the New Energy Exploration

Summary This study was stimulated by mud gas logging observation of likely drill-bit metamorphism-generated H2, and need of unbiased H2 distribution along wells drilled in exploration for naturally occurring hydrogen. The proven existence of the DBM gas by-products can flag and de-risk crucial mud gas logs for critical subsequent sampling, testing and completions decisions during hydrocarbons and H2 exploration. These successful experiments pave the way for systematic investigation of the DBM process to a wide extent, as a cautionary tale about practices used during exploration for petroleum and natural hydrogen.
