Is Tapis crude oil?

Tapis is a light sweet crude oil grade produced in southeast Asia (Malaysia). Tapis has traditionally been used as a regional benchmark crude for Asia, especially for pricing light sweet crudes.

What are the 4 main types of crude oil?

Types of Crude Oil

• Class A: Light, Volatile Oils. These oils are:
• Class B: Non-Sticky Oils. These oils have a waxy or oily feel.
• Class C: Heavy, Sticky Oils. Class C oils are characteristically:
• Class D: Nonfluid Oils. Class D oils are:

What is the best grade of crude oil?

Sulfur content and weight are the two qualities by which crude oil is typically judged. High-sulfur, heavy oils are the lowest quality and the least expensive on the global market. Low-sulfur, light oils bring the highest price because they are of the highest quality.

What is meant by crude assay?

Crude oil assay consists of a compilation of data on properties and composition of crude oils. The assay provides critical information on the suitability of crude oil for a particular refinery and estimating the desired product yields and quality.

What is Tapis oil used for?

Tapis crude oil is used as a pricing benchmark in Singapore. Tapis is very light, with an API gravity of 43°-45°, and very sweet, with only about 0.04% sulphur. While it is not traded on a market like Brent Crude or West Texas Intermediate, it is often used as an oil marker for Asia and Australia.

Where is Tapis crude from?

The Tapis field, located off the coast of Terengganu in the South China Sea was discovered in 1969 with production starting in 1978. ExxonMobil holds a 30% stake, the rest being held by state-owned Petronas. As of 2018, production is approximately 300,000 barrels per day.

How many grades of crude oil are there?

API gravity is a commonly used index of the density of a crude oil or refined products. API stands for the American Petroleum Institute, which is the industry organization that created this measure.

Why is Nigeria crude oil the best?

Nigeria’s crude oil is light and sweet; low in sulfur and yields a generous amount of diesel, jet fuel and gasoline, which are the most profitable products for global refineries. These crudes also normally command a significant premium over Dated Brent.

Why is crude assay important?

Assay data help refineries determine if a crude oil feedstock is compatible for a particular petroleum refinery or if the crude oil could cause yield, quality, production, environmental and other problems.
