A recent patent titled “Systems and Methods for Identifying Natural Hydrogen Sweet Spots in a Subsurface Formation” addresses emerging need by offering an innovative method to locate these resources more effectively.
The core concept of this patented system lies in identifying natural hydrogen sweet spots located deep within the Earth’s subsurface formations. To achieve this, the process begins with obtaining rock samples from these regions, followed by performing pyrolysis. Pyrolysis is a thermal decomposition process that helps in determining the amount of hydrogen that can be generated from the rock samples.
Once the hydrogen generation capability of the rock samples is established through pyrolysis, the next step is to determine kinetic parameters. These are based on the pyrolysis results and the thermal history of the subsurface formation. This information is then used to simulate hydrogen generation within the formation. The simulation predicts target maturity data, which is crucial for assessing the hydrogen richness of different areas within the formation.
Beyond simulation, this method involves a meticulous analysis of the rock samples’ total organic content and their maturity data. By measuring these aspects, researchers can gain a more comprehensive understanding of the formation’s characteristics. The collected data serves as a guide in identifying potential sweet spots where natural hydrogen is concentrated and can be extracted efficiently.
The ultimate goal of this patented system is to pinpoint hydrogen sweet spots in the subsurface formations. This identification is based on comparing the target maturity data with the total organic content and the measured maturity data from the rock samples. By doing so, the method provides a clear pathway to locate and exploit natural hydrogen sources optimally.
