Crude oil natural gas ratio
The individual flowrates of crude oil, natural gas and water three-phase mixture are measured separately by using a single phase flowmeter. The microwave technique is used to measure the water to oil and gas ratio. This instrument is not temperature or salinity sensitive - a shortcoming of the capacitance and conductivity probes. The capacitance cross-correlation method is used to measure the overall flowrate of a three-phase fluid.

A summary treatment of crude oil follows. For full treatment, see petroleum , petroleum production , and petroleum refining. Crude oil is a mixture of comparatively volatile liquid hydrocarbons compounds composed mainly of hydrogen and carbon , though it also contains some nitrogen , sulfur , and oxygen. Those elements form a large variety of complex molecular structures, some of which cannot be readily identified. Regardless of variations, however, almost all crude oil ranges from 82 to 87 percent carbon by weight and 12 to 15 percent hydrogen by weight.
Crude oils are customarily characterized by the type of hydrocarbon compound that is most prevalent in them: paraffins , naphthenes , and aromatics. Paraffins are the most common hydrocarbons in crude oil; certain liquid paraffins are the major constituents of gasoline petrol and are therefore highly valued. Naphthenes are an important part of all liquid refinery products, but they also form some of the heavy asphalt like residues of refinery processes.
Aromatics generally constitute only a small percentage of most crudes. The most common aromatic in crude oil is benzene , a popular building block in the petrochemical industry. Because crude oil is a mixture of such widely varying constituents and proportions, its physical properties also vary widely. In appearance, for instance, it ranges from colourless to black. Possibly the most important physical property is specific gravity i. In laboratory measurement of specific gravity, it is customary to assign pure water a measurement of 1; substances lighter than water, such as crude oil, would receive measurements less than 1.
Liquids lighter than water, such as oil, have API gravities numerically greater than On the basis of their API gravity, crude oils can be classified as heavy, medium, and light as follows:. Sweet crudes have sulfur contents of 0. Generally, the heavier the crude oil, the greater its sulfur content. Excess sulfur is removed from crude oil during refining, because sulfur oxides released into the atmosphere during combustion of oil are a major pollutant.
In the United States, the conventional practice for the petroleum industry is to measure capacity by volume and to use the English system of measurement. For this reason, crude oil in the United States is measured in barrels , each barrel containing 42 gallons of oil. Most other areas of the world define capacity by the weight of materials processed and record measurements in metric units; therefore, crude oil outside the United States is usually measured in metric tons. Crude oil occurs underground, at various pressures depending on depth.
It can contain considerable natural gas , kept in solution by the pressure. In addition, water often flows into an oil well along with liquid crude and gas. All these fluids are collected by surface equipment for separation. Clean crude oil is sent to storage at near atmospheric pressure , usually aboveground in cylindrical steel tanks that may be as large as 30 metres feet in diameter and 10 metres 33 feet tall.
Often crude oil must be transported from widely distributed production sites to treatment plants and refineries. Overland movement is largely through pipelines. Crude from more isolated wells is collected in tank trucks and taken to pipeline terminals; there is also some transport in specially constructed railroad cars. Overseas transport is conducted in specially designed tanker ships.
Tanker capacities vary from less than , barrels to more than 3,, barrels. The primary destination of crude oil is a refinery. There any combination of three basic functions is carried out: 1 separating the many types of hydrocarbon present in crude oils into fractions of more closely related properties, 2 chemically converting the separated hydrocarbons into more desirable reaction products, and 3 purifying the products of unwanted elements and compounds.
The main process for separating the hydrocarbon components of crude oil is fractional distillation. Crude oil fractions separated by distillation are passed on for subsequent processing into numerous products, ranging from gasoline and diesel fuel to heating oil to asphalt.
Given the pattern of modern demand which tends to be highest for transportation fuels such as gasoline , the market value of a crude oil generally rises with increasing yields of light products. Crude oil.

The oil price to natural gas ratio compares prices of crude oil and natural gas and is used as a measure of demand for each commodity. Energy analysts, traders and investors use the ratio when gauging the market of oil versus that of natural gas. In the oil price to natural gas ratio formula, the oil price is the numerator and the price of natural gas is the denominator. Crude oil and natural gas are both energy commodities that trade on commodities markets and have a common use as fuels for heating. The higher the oil price to natural gas ratio, the greater the demand for oil. If the ratio declines, then the difference in the prices of the two commodities is narrowing.
Futures Pairs: Crude Oil vs. Natural Gas
It is commonly refined into various types of fuels. Components of petroleum are separated using a technique called fractional distillation , i. It consists of naturally occurring hydrocarbons of various molecular weights and may contain miscellaneous organic compounds. A fossil fuel , petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae , are buried underneath sedimentary rock and subjected to both intense heat and pressure. Petroleum has mostly been recovered by oil drilling natural petroleum springs are rare. Drilling is carried out after studies of structural geology at the reservoir scale , sedimentary basin analysis, and reservoir characterisation mainly in terms of the porosity and permeability of geologic reservoir structures have been completed. The use of petroleum as fuel causes global warming and ocean acidification. According to the UN 's Intergovernmental Panel on Climate Change , without fossil fuel phase-out , including petroleum, there will be "severe, pervasive, and irreversible impacts for people and ecosystems ". Petroleum, in one form or another, has been used since ancient times, and is now important across society, including in economy, politics and technology.
Crude oil and natural gas are both energy commodities. As such, we use these fuels to heat and cool our homes or supply other energy needs.

Natural gas also called fossil gas is a naturally occurring hydrocarbon gas mixture consisting primarily of methane , but commonly including varying amounts of other higher alkanes , and sometimes a small percentage of carbon dioxide , nitrogen , hydrogen sulfide , or helium. The energy that the plants originally obtained from the sun is stored in the form of chemical bonds in the gas. Natural gas is a non-renewable [3] hydrocarbon used as a source of energy for heating, cooking, and electricity generation. It is also used as a fuel for vehicles and as a chemical feedstock in the manufacture of plastics and other commercially important organic chemicals. Natural gas has an effect on climate change ; it is a greenhouse gas itself, [4] and creates carbon dioxide during oxidation. Natural gas can be used in place of coal , for example, to generate electricity , which may lower net carbon dioxide emissions in absence of carbon capture. Natural gas is found in deep underground rock formations or associated with other hydrocarbon reservoirs in coal beds and as methane clathrates. Petroleum is another resource and fossil fuel found close to and with natural gas. Most natural gas was created over time by two mechanisms: biogenic and thermogenic. Biogenic gas is created by methanogenic organisms in marshes , bogs , landfills , and shallow sediments.
Crude Oil vs Natural Gas - 10 Year Daily Chart
The ratio between the spot prices of crude oil and natural gas has been generally increasing since January , but it has climbed rapidly in recent months see chart. Analysts calculate the ratio in different ways to assess the value of crude oil relative to natural gas; two methods are shown in the chart above. The ratio increased because of both increasing crude oil prices and decreasing natural gas prices. The crude oil-to-natural gas spot price ratio has implications for production and consumption. Several factors underpin the increase in global crude oil benchmarks since the start of the year. Natural gas spot prices have been near year lows as a result of warmer-than-normal temperatures, ample natural gas in storage, and growing production. In terms of production implications, a higher crude oil-to-natural gas ratio encourages drilling for oil in preference to natural gas and makes natural gas liquids developments relatively more attractive than the development of dry natural gas resources.
