What is Overlift and Underlift?

Overlift/Underlift means, in relation to the interest of the Seller in a Field, the amount in barrels by which the aggregate amount of Oil, or NGL products in metric tonnes, or Gas as described in the hydrocarbon accounts prepared by the Field Operator, lifted by the Seller on and before the Completion Date exceeds (in

Keeping this in consideration, what are p1 p2 and p3 reserves?

There are various different levels of "proven" oil reserves (P1, P2, P3) for crude oil reserves. They can be summarized as follows (from Jean Laherrere): Proved 1P - at least 90% probability. Proved + Probable 2P - at least 50% probability. Proved + Probable +Possible 3P - at least 10 % probability.

One may also ask, what is oil and gas accounting all about? Oil and gas operations have some of the most unique accounting issues found in any industry. Oil & Gas Accounting delves into acquisition, exploration, development, and production activities, covering many industry-specific accounting issues.

Hereof, what is the difference between proven and unproven reserves?

In the oil and gas sector, proven reserves have a reasonable certainty of being recovered, while unproven reserves have a decreased level of certainty in being recovered. Recoverable oil reserves are the amount of oil that can reasonably be recovered given current technical and economic conditions.

What is the oil reservoir called?

A petroleum reservoir or oil and gas reservoir is a subsurface pool of hydrocarbons contained in porous or fractured rock formations.

What are the three categories of reserves?

There are 3 main reserve categories under the Society of Petroleum Engineers (SPE) definition: proved; probable and possible reserves. For an oil or gas deposit to be classified as “reserves,” you first need to establish technical and commercial certainty of extraction using existing technology.

What is 2p and 3p reserves?

"2P reserves" = 1P (proven reserves) + probable reserves, hence "proved AND probable." "3P reserves" = the sum of 2P (proven reserves + probable reserves) + possible reserves, all 3Ps "proven AND probable AND possible."

What is 1p and 2p reserves?

The term 1P is frequently used to denote proved reserves, 2P is the sum of proved and probable reserves and 3P the sum of proved, probable and possible reserves. The best estimate of recovery from committed projects is generally considered to be the 2P sum of proved and probable reserves.

Where is there oil in the world?

Based on data from OPEC at the beginning of 2013 the highest proved oil reserves including non-conventional oil deposits are in Venezuela (20% of global reserves), Saudi Arabia (18% of global reserves), Canada (13% of global reserves), and Iran (9%).

What are proven and probable reserves?

Proved reserves sit at the top of the scale, at a 90-percent or above likelihood of commercial extraction. Probable reserves are those with the likelihood of recovery for between possible and proved reserves, or over 50-percent but under 90-percent.

What are 3p reserves?

3P oil reserves are the total amount of reserves that a company estimates having access to, calculated as the sum of all proved and unproved reserves.

What are proved undeveloped reserves?

Proved Undeveloped Reserves Law and Legal Definition. According to the Oil and Gas laws of United States, Proved Undeveloped Reserves means reserves that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion.

What is peak oil and why is it important?

Peak oil is important because it marks the peak of production of “cheap” oil, generally considered to be conventional crude oil.

How much oil is left in the world?

Now for some hard numbers. In its latest Statistical Review of World Energy, BP estimated the world had 1.7297 trillion barrels of crude oil remaining at the end of 2018. That was up from 1.7275 trillion barrels a year earlier and 1.4938 trillion barrels in 2008.

What are proven resources?

Proved reserves is a classification used in mining sectors that denotes the amount of hydrocarbon resources that can be recovered from the deposit with a reasonable level of certainty. Proved reserves is a common metric quoted by companies such as oil, natural gas, coal and other commodity-based companies.

What is a proven oil reserve?

Proven reserves are those quantities of petroleum which, by analysis of geological and engineering data, can be estimated, with a high degree of confidence, to be commercially recoverable from a given date forward from known reservoirs and under current economic conditions.

What does behind pipe mean?

Glossary:Behind pipe reserves. Behind-pipe reserves are expected to be recovered from zones in existing wells, which will require additional completion work or future recompletion prior to the start of production.

Are reserves considered part of references for fuel?

For fuels, the total occurrence includes the discovered and undiscovered deposits, economically recoverable or not economically recoverable. On the other hand, reserves are deposits of fossil fuels that are known to exist with a reasonable level of certainty based on geological and engineering studies.

What is a potential reserve?
