Some positive effects of earthquakes:-
Earthquakes are very useful to humans because they provide a picture of what's going on underground. This can make oil and gas extraction more efficient, and allows scientists to monitor the progress of water during geothermal energy extraction.
Answer:
Like many other natural hazards, earthquakes provide many natural service functions. Thus the positive effects of earthquakes include: influencing the flow of underground water, oil and natural gas, make mineral resources available, landform development, monitoring the inside of Earth and producing seismic hazard assessments for designing earthquake-resistant structures.
Explanation:
Artificially made seismic waves have been used for both tertiary recovery and well stimulation purposes. The idea behind using this method for enhancing recovery came from a number of real examples, in which a kick in oil production has been seen following an earthquake. Most published information has addressed the United States and earlier Soviet Union regions. This paper documents the results of observations regarding the effect of earthquake waves on well production from Khami carbonate gas condensate reservoir in the Marun field, in the northern Persian Gulf. The response of three wells in this reservoir (referred to as wells A, B, and C) to a magnitude earthquake at an approximate distance of 217 km away is discussed. After this earthquake, there was a sharp significant increase in production from well A. The flowing wellhead pressure of this well suddenly increased from 4263 to 5042 psig and went back to its normal condition after five months. The two other wells behaved differently and showed no change in production. Analyses showed the removal of near wellbore formation damage caused by a condensate dropout in well A using natural seismic waves.
