It is crucial to ensure the safety and integrity of underground gas storage (UGS) infrastructure for energy reliability in California, many other places around world. To address risk management need UGS industry, we take advantage recent advances downhole fiber optic monitoring coupled well-reservoir simulation provide unprecedented understanding flow wells at sites. We have combined advanced o...

Several low-cost opportunities exist for scrubbing CO2 from waste gas streams, utilizing spontaneous chemical reactions in the presence of water and inexpensive or waste alkaline compounds. These reactions convert CO2 to bicarbonate or carbonate in dissolved or solid form, thus providing CO2 capture and low-risk CO2 storage underground, in the ocean, or in some cases on land. Useful by-products...

Underground gas storage is the best choice for natural resource reserve and peak value. Storage capacity of underground single well injection production are key indicators shaving capacity. This paper focuses on research expansion stimulation a basin in Western China. Firstly, based study two-phase seepage law water, numerical simulation model coupling high velocity non-Darcy effect gas-water t...

The share of molecular hydrogen as a source “green energy” is currently significantly increasing. It proposed to use existing underground natural gas storage facilities store large volumes hydrogen. In Russia, depleted oil and fields (DOGFs) deep aquifers are used for storage. purpose this work was determine microbial diversity in DOGF by cultural 16S rRNA gene-based approaches the effect H2 on...

Underground storage of natural gas represents an efficient solution to cover fluctuations in consumption during the cold season and/or special situations like emergencies. The paper aims presents underground storages technologies saline deposits and depleted reservoirs, as well pros cons features using those methods..
