Only a small percentage of induced seismicity comes from fracking processes that
inject liquid into the ground to break up rock layers to free
oil and gas for
recovery.
Instead, the proliferation of hundreds of small earthquakes in that part of the U.S. is thought to be caused primarily by massive amounts of wastewater
injected back into the ground after
oil and gas
recovery.
Industrial - scale carbon capture facilities like the Great Plains Synfuel Plant in Beulah, North Dakota (which pipes CO2 to Canada, where it is
injected into
oil wells to improve
oil recovery), already exist, and leaks have never been detected.
They looked both at wells used for enhanced
oil recovery — in which fluid is
injected to flush lingering
oil from a depleted reservoir — and at those used to dispose of wastewater from conventional
oil and gas extraction or from hydraulic fracturing (fracking).
In the U.S., these earthquakes have been linked primarily to massive amounts of wastewater
injected back into the ground after
oil and gas
recovery.
CO2 has been
injected in many oilfields for over 40 years now, for enhancing
oil recovery, and none, to my knowledge have reported verifiable CO2 leaks.
CO2 has been
injected in many oilfields for over 40 years now, for enhancing
oil recovery, and none, to my knowledge have reported verifiable CO2 leaks.
Likewise, the extraction of
oil and natural gas using enhanced
recovery techniques, and handling of
injected and produced water, raise state and federal concerns for
oil, gas, and geothermal energy production.
But to win money from the newly - available federal Clean Coal Power Initiative, Southern now promised to also use TRIG to capture most of the plant's carbon dioxide, which would be compressed and piped out to older underproducing
oil fields and
injected into the ground to drive more
oil to the surface — a process called enhanced
oil recovery.
This technology was also well known, since the
oil industry had been
injecting limited quantities of CO2 to enhance
oil recovery.
When storage is combined with enhanced
oil recovery to extract extra
oil from an
oil field, the storage could yield net benefits of US$ 10 — 16 per tonne of CO2
injected (based on 2003
oil prices).
Instructs the Secretary of Energy to: (1) establish a competitive grant program for
oil and gas producers to implement projects to
inject carbon dioxide to enhance
recovery of
oil or natural gas while increasing carbon dioxide sequestration; and (2) assess and report to Congress on the economic implications of the dependence of Hawaii on
oil as its principal source of energy.
Meanwhile the demand is rising for carbon dioxide to
inject into depleted
oil wells, a technique known as enhanced
oil recovery.
Sure, CO2 can be
injected into wells — I think it's a fairly common technique used to increase
recovery from marginal
oil wells.
The separation process could increase the amount of fuel obtained by enhanced
oil recovery using carbon dioxide
injected into existing reservoirs.
