Q: Does drilling for oil and gas cause or trigger earthquakes?
A: Research carried out by UTIG scientists suggests that earthquakes in some parts of Texas may be induced by the pumping of fluids at oil and gas fields, or by the injection of fluids to dispose of chemical wastes. The earthquakes in the Fashing-Pleasanton area southeast of San Antonio are almost certainly caused by or triggered by pumping; such earthquakes also seem to occur in the Texas Panhandle near Snyder, Texas.

I have been researching the claim of the earthquake on Aceh (Indonesia 12/26/2004) earthquake and tsunami caused by Oil/Gas drilling.
It seems that EXXON has a 60 BSCF/day facility near Aceh and in 4 years it withdraws the equal of about 1+ Cubic Mile of Natural Gas from the formations directly at Epicenter of the Earthquake.
Also note that the gas field there has been producing for quite some time not just 4 years.
It is also interesting to note that earthquakes in the order 4.0 have been caused by oil drilling etc for some time.
There have been earthquakes associated with large Hydro Dams for example Fontana Dam (USTVA North Carolina) has been associated with up to 4.0 earthquakes and routinely causes 2.5 some 50+ years after construction. I would expect the 3 Gorges Dam in China to create 7.0 or larger earthquakes and this represents pressures and masses in the same order as the Oil/Gas stuff. While I have no doubt of the regional earthquake history I could easily suspect a real and substantial component to the event of 12/26/2004.

Between 1977 and 2008, there were a total of 28 earthquakes recorded in Oklahoma and Lincoln Counties. However, in the last year and a half, there have been 134.
Many have asked if the oil and gas industry has had anything to do with the recent increase in quakes in Oklahoma.

Stump and other geologists said production wells have not been tied to earthquakes, but disposal wells, where the saltwater and other fluids used in oil and gas production are injected back into the earth have been shown, in some cases, to cause small quakes.
"Fluids of all kinds, when they're injected underground, do, in some cases, induce small earthquakes," Stump said.
