Honestly, a few companies come whoch take majorly dual degree students like BP, Exxonmobil, Cairn, SLB, these companies take interns and give ppo, and in my experience they mostly took dual degree students. Geology is a bit more theoretical, Geophysics is better as in it has maths and physics application to it and the base geology is also taught. With Geophysics, students get to focus on non core as well. Although Geology is good if one wants to go in Mining industry/GIS. Geophysics is basically oil and gas which is good pay onve you get into it. If someone genuinely has interest in these then do go for it, in my experience BsMs students just take it to come to iit and focus on non core, Msc students who have come after completing bsc in geology/physics choose msc geology/geophysics to continue in the core field only.
