Since 1996, the Norwegian company Statoil has been stripping about a million tons of CO2 a year out of natural gas from the Sleipner West field under the North Sea and injecting it at high pressure into a saline aquifer.

A new vehicle that has direct injection, variable valve timing (and possibly lift) will usually (not a rule of thumb, though) run less timing due to the fuel being injected at higher pressures.

Not exact matches

Scientists have understood since the 1960s that injecting fluid into the ground at high pressure can cause earthquakes.

Fracturing deep shale deposits by injecting them with water, sand and chemicals at high pressure — with the aim of releasing the gas they hold — is causing concern worldwide.

Fracking, which injects liquids underground at high pressure to extract oil and natural gas from hard to reach places, can contaminate water (SN Online: 10/12/15) and air, due to chemicals used in the process.

InSAR uses a highly accurate radar to measure the change in distance between the satellite and ground surface, allowing the team to show that injecting water into the wells at high pressure caused ground uplift near the shallower wells, the release said.

This process involves injecting a slurry of water, chemicals and sand into wells at high pressure to fracture the rock and create veins that can carry trapped gas to the well.

Normally, the reaction happens too slowly to be useful, but injecting carbon dioxide into the rock at high pressure would speed things up considerably; the formation of magnesium carbonate could cause the rock to expand and crack, with the increased surface area spurring the reaction to continue.

In the right locations, CO2 injected into the ground at high pressure would react with those minerals to form stable carbonate rock.

The 600 - plus - page report that resulted looks at a variety of ways fracking could have an effect on local drinking water: withdrawing millions of gallons of water needed to frack a well, improperly mixing chemicals with the water at the well, injecting that fracking fluid into the ground at high pressure to fracture rock as much as two miles beneath the surface, handling the contaminated water then produced by the well and finally improperly storing or disposing of that water.

Hydraulic fracturing, or fracking, is a drilling process that injects millions of gallons of water, sand and undisclosed chemicals at high pressure into horizontal wells to crack...

Injecting fluids into the Earth at high pressure can have consequences: causing earthquakes; contamination of surface aquifers by the injected fluid; and by connecting together of shallow geological layers (like drinking water aquifers and shallow coals seams) by the numerous boreholes required, some of which will have faulting casing and cement jobs.

Developers drill into the shale formations and inject a mixture of water and sand at very high pressures.

We believe that fracking poses a tremendous threat to agriculture, to our drinking water, and to our climate, because when you are injecting millions of gallons of water, chemicals and sand, four or five miles underground at very high pressure and breaking open the rock and releasing gas there's all sorts of contamination that can happen.
