Some of those quakes can continue years after the
fluid injection is stopped.
"The commission has long recognized the possibility of induced seismicity related to
fluid injection; that's why the [commission] has in place some of the most stringent rules in the nation to address the issue," she said.
With a 0.014" guidewire deployed through the RX lumen into the main branch, the OTW lumen can be used for guidewire exchange, subsequent delivery of a second guidewire into a side branch, or
fluid injection to a desired distal vessel segment.
The injection pump is capable of continuous
fluid injection at a specified constant rate (0.01-50 cc/min) and injection pressure as high as 10,000 psi.
"However, we do know that many earthquakes in Oklahoma have been triggered by wastewater
fluid injection."
However, a
fluid injection injury could easily be incurred if pressurised fluid from such a leak makes contact with the inspector's skin.
"The PDA-Human Amniotic
Fluid Injection is a great treatment option for relieving chronic pain without having to endure the undesirable downtime and cost of surgery." -Patient, 64 years old
The device features a built-in deployed endometrial sampling brush, a low profile malleable insertion catheter, a repositionable cervical sealing mechanism for uterine distension designed to not obscure the lower uterine segment, and a 50-cc refillable
fluid injection bag.
If the slow sliding could be monitored, the
fluid injection rate could possibly be tweaked to avoid earthquakes, geophysicist Francois Cornet writes in an accompanying commentary.
The first and most famous example of man-made earthquakes or "induced seismicity" due to
fluid injection was reported at the Rocky Mountain Arsenal in the 1960s and 1970s.
