We have presented a theoretical study of the dust acoustic （DA） shock structures in a magnetized, electron depleted dusty plasma in the presence of two temperature superthermal ions. By deriving a Korteweg-de Vries-Burgers equation and studying its shock solution, we aim to highlight the effects of magnetic field and obliqueness on various properties of the DA shock structures in the presence of kappa-distributed two temperature ion population. The present model is motivated by the observations of Geotail spacecraft in the Earth＇s magnetotail and it is seen that the different physical parameters such as superthermality of the cold and hot ions, the cold to hot ion temperature ratio, the magnetic field strength, obliqueness and the dust kinematic viscosity greatly influence the dynamics of the shock structures so formed. The results suggest that the variation of superthermalities of the cold and hot ions have contrasting effects on both positive and negative polarity shock structures. Moreover, it is noted that the presence of the ambient magnetic field affects the dispersive properties of the medium and tends to make the shock structures less wide and more abrupt. The findings of present investigation may be useful in understanding the dynamics of shock waves in dusty plasma environments containing two temperature ions where the electrons are significantly depleted.

Majority of geologic CO_(2) storage sites for currently operated large-scale integrated carbon capture and storage projects(LSIPs)in operation around the world are depleted oil fields that have been undergone significant depletion and re-pressurization prior to injection of captured CO_(2).A better understanding of any of the implications associated with past depletion and re-pressurization histories to“out of injection zone”migration of injected CO_(2) can help in making monitoring strategies significantly more *** the geologic CO_(2) storage demonstration sites for two most active LSIPs in the US,the West Hastings and the Bell Creek Oil Fields are the main focus of present *** monitoring technologies that have been used/deployed/tested at both the normally pressured West Hastings and the subnormally pressured Bell Creek storage sites appear to adequately address any of the potential“out of zone migration”of injected CO_(2) at these *** would be interesting to see if any of the collected monitoring data at the West Hastings and the Bell Creek storage sites could also be used in future to better understand the viability of initially subnormally pressured and subsequently depleted and re-pressurized oil fields as secure geologic CO_(2) storage sites with relatively large storage CO_(2) capacities compared to the depleted and re-pressurized oil fields that were initially discovered as normally pressured.
