What is Oil Reserves?

Oil reserves are an estimate of the amount of crude oil located in a particular economic region with the potential of being extracted. Reserves are calculated based on a proven probable basis and oil pools situated in unattainable depths are not considered part of a nation's reserves.

Definition

Oil reserves refer to the estimated quantities of crude oil located in a specific economic region that can potentially be extracted. These reserves are calculated based on empirically reasonable foundations, and oil deposits located at unreachable depths are not considered part of a country's reserves.

Origin

The concept of oil reserves originated in the early 20th century when oil became a crucial resource for the global economy. As technology advanced and geological exploration deepened, methods for estimating oil reserves have gradually improved.

Categories and Features

Oil reserves are typically classified into proven reserves, probable reserves, and possible reserves. Proven reserves are known quantities that can be economically extracted; probable reserves are those that might be extracted under current technological conditions; possible reserves are those that might be extracted with future technological advancements. Proven reserves have the highest reliability, while possible reserves carry the greatest risk and uncertainty.

Case Studies

A typical case is the Ghawar Field in Saudi Arabia, the largest conventional oil field in the world, with significant proven reserves impacting the global oil market. Another example is the shale oil revolution in the United States, where hydraulic fracturing technology significantly increased U.S. oil reserves, altering the global energy landscape.

Common Issues

Investors often misunderstand the estimation of oil reserves, assuming all reserves can be immediately extracted. In reality, the extraction of reserves is influenced by technological, economic, and political factors. Additionally, the uncertainty in reserve estimation can lead to investment risks.

Interest Rate Future

An interest rate future is a futures contract with an underlying instrument that pays interest. The contract is an agreement between the buyer and seller for the future delivery of any interest-bearing asset.The interest rate futures contract allows the buyer and seller to lock in the price of the interest-bearing asset for a future date.

Historic Pricing

Historic pricing is a unit pricing method used to calculate the value of an asset using the last valuation point calculated. Historic pricing is used when the value of an asset does not update in real time.

Rational Behavior

Rational behavior refers to a decision-making process that is based on making choices that result in the optimal level of benefit or utility for an individual. The assumption of rational behavior implies that people would rather take actions that benefit them versus actions that are neutral or harm them. Most classical economic theories are based on the assumption that all individuals taking part in an activity are behaving rationally.

Discrete Distribution

A Discrete Distribution, also known as a Discrete Probability Distribution, refers to a probability distribution in statistics and probability theory where the random variable can take on a finite or countably infinite number of specific values. Common examples of discrete distributions include the binomial distribution, Poisson distribution, and geometric distribution. In a discrete distribution, each possible value has an associated probability, and the sum of these probabilities is equal to 1. Discrete distributions are widely used in finance, insurance, engineering, and other fields to describe and analyze the probabilities of discrete events. For instance, the number of times a stock price changes, the number of insurance claims, and similar discrete occurrences can be modeled and analyzed using discrete distributions.

White Elephant

A white elephant is something whose cost of upkeep is not in line with its usefulness or value. From an investmentperspective, the term refers to an asset, property, or business that is so expensive to operate and maintain that it is extremely difficult to actually make a profit from it.White elephants also tend to be illiquid assets, meaning they cannot be easily or quickly exchanged or sold for cash without the seller experiencing a significant loss.

Lehman Formula

The Lehman formula is a compensation formula developed by Lehman Brothers to determine the commission on investment banking or other business brokering services. Lehman Brothers developed the Lehman Formula, also known as the Lehman Scale Formula, in the 1960s while raising capital for corporate clients.
