Abstract
Embodiments of the invention relate to methods, systems, and software for identifying and quantifying subsurface hydrogen, helium, carbon dioxide, or other fluids using multiple indicia from geophysical well logs, other wireline logging tools, or mudlogging tools.
Claims17
A method for drilling a borehole to a depth of geologic hydrogen in a rock formation, the method comprising:
- identifying a geological area of interest;
- determining a rock matrix type of the rock formation at the geological area of interest;
- determining a porosity of the rock formation;
- determining a fluid density of a fluid within a pore space of the rock formation;
- determining an acoustic slowness of the fluid within the pore space;
- differentiating the geologic hydrogen from hydrocarbon fluids or other subsurface fluids within the fluid using geophysical acoustic logs;
- differentiating the geologic hydrogen from water within the fluid using geophysical density logs;
- flagging the differentiated geologic hydrogen, wherein the flagging includes providing the depth within the rock formation having geophysical properties indicative of a presence or an amount of the differentiated geologic hydrogen;
- and
- in response to determining the differentiated geologic hydrogen, drilling a borehole in the rock formation to the depth of the differentiated geologic hydrogen.

A system for drilling a borehole to a depth of geologic hydrogen in a rock formation, the system comprising:
- a computing device having a processor and memory storage operably coupled to the processor, the memory storage storing one or more operational programs including machine readable and executable instructions that, when executed, cause the computing device to:
- determine a rock matrix type of the rock formation at a geological area of interest;
- determine a porosity of the rock formation;
- determine a fluid density of a fluid within a pore space of the rock formation;
- determine an acoustic slowness of the fluid within the pore space;
- differentiate the geologic hydrogen from hydrocarbon fluids or other subsurface fluids within the fluid using geophysical acoustic logs;
- differentiate the geologic hydrogen from water within the fluid using geophysical density logs;
- flag the differentiated geologic hydrogen, wherein flagging includes providing the depth within the rock formation having geophysical properties indicative of a presence or an amount of the differentiated geologic hydrogen;
- and
- a drill rig configured to drill the borehole in the geological area of interest to the depth of the differentiated geologic hydrogen in response to the computing device determining the differentiated geologic hydrogen.
