re: Lawmakers rush to stop 'catastrophic-level event' at Texas oil fields

Water production is standard during oil & gas production. But I have 2 questions for you oil baws.

1. Aside from organic material/pollutants/etc deposited during climatic events(ex: peat accumulation in bottomlands after percolation/evaporation post-flood events), isn't virtually everything dissolved in brine, and oil for that matter, derived from the local minerals/soils? Take calcium for instance. Limestone is Calcium carbonate. If you have excess water in that soil horizon/formation(due to an aquifer for instance), some of the limestone would dissolve and the resultant solution would contain calcium ions, no? And the amount would increase with volume of water, temperature/heat, and/or appearance of catalysts(CO2) that could aid in increasing solubility

2. If 1 is true, then mineral extraction is essentially just removing large amounts of sub-surface soil using drilling fluid and other chemicals to aid in dissolving whatever soil(mineral found in it) is the target. I would assume the only reason this doesn't cause major ecological issues(land slides, sinkholes, earthquakes) is due to cementing at each end of the well bore and replacing what was extracted with an equivalent volume of water. But if evaporites, salt formations, were to be drilled into/extracted, wouldn't it cause those 3 ecological issues? Replacing the volume removed would be almost impossible due to salts high solubility in water

Seems to me that if enough salt were removed, it would cause a cataclysmic land slide/migration and the end result would be a surface that looks something like grand canyon
