A Trajectory Optimization Design Method for the Directional Wells in Jintan Salt-Cavern Underground Gas Storage of Jiangsu

Shiyou jixie, 2021
The lower vertical section in the directional well of salt-cavern underground gas storage is too short, which leads to partial solution of salt cavity because the solution mining string is not vertical in the late stage.

Recovery Factor of Pure Helium Injection in Depleted Gas Reservoirs and Its Influencing Factors

Energy Science &Engineering, Volume 14, Issue 8, Page 3922-3934, August 2026.
This study employs compositional numerical simulation to systematically investigate the effects of injection rate, production rate, storage duration, and injection‐production scheme on pure helium recovery in depleted gas reservoirs. Low injection rates reduce viscous fingering while high production rates maximize near‐wellbore helium extraction ...

Systematic Approach for Carbonate and Volcanic Facies Classification Based on Textural and Structural Variations Observed in Brazilian Pre‐Salt Acoustic Image Logs

Journal of Petroleum Geology, Volume 49, Issue 3, Page 869-906, July 2026.
ABSTRACT Facies characterization in carbonate reservoirs remains challenging due to their pronounced textural and structural heterogeneity. Variations in grain packing, cementation, and diagenetic overprints produce contrasting acoustic responses in borehole image logs, often limiting the reproducibility of facies interpretation.

Potential risk of H 2 S generation and release in salt cavern gas storage [PDF]

Journal of Natural Gas Science and Engineering, 2017
Abstract The storage of natural gas in salt caverns can entail the risk of H2S generation, which in turn leads to gas pollution. H2S is generated by bacterial sulfate reduction. The bacteria use aqueous sulfate(aq) as an electron acceptor to oxidize the dissolved hydrocarbons and generate sulfide.
