Whether an emulsion of oil and water turns into a " water-in-oil " emulsion or an " oil-in-water " emulsion depends on the volume fraction of both phases and the type of emulsifier ( surfactant ) ( see Emulsifier, below ) present.

After an oil drilling operation in 1903 in Dexter, Kansas, produced a gas geyser that would not burn, Kansas state geologist Erasmus Haworth collected samples of the escaping gas and took them back to the University of Kansas at Lawrence where, with the help of chemists Hamilton Cady and David McFarland, he discovered that the gas consisted of, by volume, 72 % nitrogen, 15 % methane ( a combustible percentage only with sufficient oxygen ), 1 % hydrogen, and 12 % an unidentifiable gas.

Secondary dolomitization of limestone is common, where calcite or aragonite are converted to dolomite ; this reaction increases pore space ( the unit cell volume of dolomite is 88 % that of calcite ), which can create a reservoir for oil and gas.

The exploding and burning of approximately 700 oil wells in Kuwait also created staggering levels of atmospheric pollution, spewed oily soot into the surrounding areas, and produced lakes of oil in the Kuwaiti desert equal in volume to twenty times the amount of oil that poured into the gulf, or about.

In addition, nearly all tanks containing oil or other hazardous chemicals are required to have containment barriers set up around them to contain 100 % of the volume of the tank in the event of a catastrophic tank failure.

Adding oil in no more than a 1: 1 ratio with the egg yolk by volume produces a water soluble medium with many of the color effects of oil paint, although it cannot be painted thickly.

Initially maritime VSAT was using Single Channel Per Carrier-SCPC technology-which suited large volume users like oil drilling rigs and oil platforms and large fleets of ships from one shipowner sailing within one or few satellite footprints.

For example, " brake fluid " is hydraulic oil and will not perform its required function if there is gas in it.

* Oil filter, a filter to remove contaminants from engine oil, transmission oil, lubricating oil, or hydraulic oil

* Diaphragm pumps-similar to plunger pumps, where the plunger pressurizes hydraulic oil which is used to flex a diaphragm in the pumping cylinder.

It is widely used on car engine oil pumps, and also in various hydraulic power packs.

They can be electromechanical actuators such as an electric motor or solenoid, pneumatic actuators which are controlled by air pressure, or hydraulic actuators which are controlled by the pressure of a liquid such as oil or water.

Derivatives of guar gum that has been further reacted is also used in industrial applications, such as the paper and textile industry, ore flotation, the manufacture of explosives and hydraulic fracturing ( fracking ) of oil and gas formations.

In 1947 Indiana Standard was the first company to drill off-shore, in the Gulf of Mexico, and in 1948 Stanolind Oil invented Hydrafrac, a hydraulic well fracturing process that increased oil production worldwide.

This version, after the mid-1970s, saw little change with the incorporation of electronic ignition in 1988, an anti-theft alarm system in 1990, a catalytic converter in 1991 ( as required by law ), as well as electronic Digifant fuel injection, hydraulic valve lifters, and a spin-on oil filter in 1993.

The study covered the energy sector, particularly in terms of process optimization fluids, nuclear or oil phase flow, hydraulic turbines, new energy sources

The Eagle Ford oil field was reported to be under development in 2011 with 3, 000 wells projected to extract oil by hydraulic fracturing from tight shale formations.

Around 2011, three new plants are opening on the east side of town to process sand for hydraulic fracturing of oil and gas wells.

A slow leak of highly flammable hydraulic oil was ignited by the burning heater, which in turn melted the plastic fluid lines further feeding the flames, and also resulting in the hydraulic pressure loss which caused the train to stop and the doors to fail.

Industry uses yearly 600-800 million pounds of castor oil and its derivatives have applications in the manufacturing of soaps, lubricants, hydraulic and brake fluids, paints, dyes, coatings, inks, cold resistant plastics, waxes and polishes, nylon, pharmaceuticals and perfumes.

In March, Statoil dropped about 1. 6 tons of pure hydraulic oil in the Barents Sea.

The cylinder contains a charge of compressed air, as well as hydraulic oil ; in operation, the barrel's energy is taken up in compressing the air as the barrel recoils backward, then is dissipated via hydraulic damping as the barrel returns forward to the firing position.

* Firewalls can be used to separate high value transformers at an electrical substation in the event of a mineral oil tank rupture and ignition.

The brazier, burning a match of linen or flax that produced intense heat and the characteristic thick smoke, was used to heat oil and the other ingredients in an airtight tank above it, a process that also helped to dissolve the resins into a fluid mixture.

The oil-filled tank often has radiators through which the oil circulates by natural convection.

Since the engine does not have an oil injection system, two-stroke oil has to be added to the fuel tank every time the car was filled up, at a 50: 1 or 33: 1 ratio of fuel to oil.
