If the pressure required to inject waste fluid through a disposal well has increased by an order of magnitude then either the formation is full or the rate of injection is quicker than the waste can disperse .

Common sense dictates that injection should stop .

Thus the examples of earth tremors and quakes are the result of bad practice from greedy / cash strapped operators and ineffective regulators .

Neither of these are inherent in the oil and gas industry whether using hydraulic fracturing and a manufacturing approach or not .
