Understanding Proved Undeveloped Reserves in Oil and Gas Law

Definition & Meaning

Proved undeveloped reserves refer to oil and gas reserves that are expected to be extracted from new wells on land that has not yet been drilled or from existing wells that require significant investment for recompletion. These reserves are typically associated with drilling units that are adjacent to productive units, where there is a reasonable expectation of production once drilling occurs. Claims for proved reserves on undrilled units can only be made if it is clearly demonstrated that production continuity exists from the current productive formations. Additionally, reserves cannot be counted if they rely on unproven techniques, such as fluid injection, unless those techniques have been validated through actual tests in the same area and reservoir.

Real-world examples

Here are a couple of examples of abatement:

Example 1: A company identifies an area adjacent to an existing oil field that has not been drilled. After conducting geological surveys, they determine that there is a high likelihood of discovering oil. They can classify these reserves as proved undeveloped reserves.

Example 2: A gas company plans to recomplete an existing well that has not been productive for several years but shows potential with a new technology. The company must invest significantly to bring the well back online, allowing them to classify the reserves as proved undeveloped reserves. (hypothetical example)

State-by-state differences

Examples of state differences (not exhaustive):

State Notes
Texas Proved undeveloped reserves are strictly regulated and require detailed geological assessments.
California State regulations may impose additional environmental assessments before classifying reserves.
Oklahoma Proved undeveloped reserves must meet specific criteria set by the Oklahoma Corporation Commission.

This is not a complete list. State laws vary, and users should consult local rules for specific guidance.

Comparison with related terms

Term Definition
Proved Reserves Reserves that are confirmed to be recoverable under existing economic and operating conditions.
Probable Reserves Reserves that are less certain than proved reserves but have a reasonable chance of being recovered.
Possible Reserves Reserves that are even less certain than probable reserves, with a lower likelihood of recovery.

What to do if this term applies to you

If you are involved in the oil and gas industry and believe you have proved undeveloped reserves, consider the following steps:

  • Conduct a thorough geological assessment to confirm the potential for production.
  • Consult with legal professionals to ensure compliance with state regulations and industry standards.
  • Explore US Legal Forms for templates related to resource management and investment agreements.
  • If the situation is complex, seek professional legal assistance to navigate potential challenges.

Quick facts
