Easy answer you could have come up with by yourself I think.
Crude oil, means oil straight from the ground and not refined yet.
Heavy metals means not light metals. So not iron or sodium but Lead and other heavy stuff.
Since oil comes from the ground and metals are mined from the ground, it makes sense that they could be found together.
So if the teacher wants a different answer he should have said "how is crude oil formed" or something like that.
If your question is "Is natural gas often found where crude oil is found?" then the answer is yes.
Natural gas is found along with crude oil in underground reservoirs because both are hydrocarbons formed from organic matter that decomposed over millions of years. This is why many oil fields also produce natural gas as a byproduct. Methane, the primary component of natural gas, can be found in conjunction with crude oil deposits.
Yes, methane can be found alongside crude oil in natural gas deposits. Natural gas is a mixture of hydrocarbons, with methane being the most abundant component. Methane can be extracted along with crude oil during the production process.
Oil in its natural state is called crude oil. It is a mixture of hydrocarbons that are found underground and is the raw material for producing various petroleum products.
Naphthenic based crude oil is a type of oil that contains a higher proportion of naphthenic hydrocarbons compared to other types of crude oil. These hydrocarbons have a cyclic structure, which can influence the oil's properties, such as viscosity and sulfur content. Naphthenic based crude oils are typically lighter and have lower sulfur content than heavy crude oils, making them easier to refine into gasoline and other products.
Heavy crude oil has a higher density and viscosity compared to light crude oil. Heavy crude oil also contains more impurities like sulfur and metals, which makes it more difficult and expensive to refine. Light crude oil is easier to extract, transport, and refine, making it more valuable in the market.
Impurities found in crude oil include sulfur compounds, nitrogen compounds, heavy metals, salt, and sediment. These impurities can affect the quality of the oil and must be removed through various refining processes to meet product specifications for use as fuels or petrochemical feedstocks.
Heavy crude oil is typically cheaper than light crude oil because it requires more processing to remove impurities and make it usable. This additional processing increases the overall cost of production, which is then reflected in the price of heavy crude oil compared to light crude oil. Additionally, heavy crude oil tends to have higher sulphur content, which can further increase the cost of refining.
Crude oil is mixture of many compounds. Most of the compounds are composed of hydrogen and carbon, so they are called hydrocarbons. Oxygen, nitrogen, sulfur and various trace metals also can be found in crude oil. When there is significant concentrations of sulfur, the crude is considered sour crude. See links.

If your question is "Is natural gas often found where crude oil is found?" then the answer is yes.
If your question is "Is natural gas often found where crude oil is found?" then the answer is yes.
Crude oil is found below natural gas reservoirs.
Cooking oil is but not crude oil.

There may be trace of gold in crude oil but it is not a significant component.
