U.S. Geological Survey assessment of reserve growth outside of the United States

USGS Publication: Scientific Investigations Report 2015-5091
The U.S. Geological Survey estimated volumes of potential additions to oil and gas reserves for the United States by reserve growth in discovered accumulations. These volumes were derived by using a new methodology developed by the U.S. Geological Survey and reviewed by the American Association of Petroleum Geologists Committee on Resource Evaluation.

Reserve Growth of Oil and Gas Fields

Investigations and Applications

USGS Publication: Scientific Investigations Report 2013–5063
The reserve growth of fields has been a topic for ongoing discussion for over half a century and will continue to be studied well into the future. Understanding past methods of estimating future volumes based on the data assembly methods that have been used can lead to a better understanding of their applicability.

Remaining Recoverable Petroleum in Giant Oil Fields of the Los Angeles Basin, Southern California

USGS Publication: Fact Sheet 2012–3120, v. 1.1
Using a probabilistic geology-based methodology, a team of U.S. Geological Survey (USGS) scientists recently assessed the remaining recoverable oil in 10 oil fields of the Los Angeles Basin in southern California. The results of the assessment suggest that between 1.4 and 5.6 billion barrels of additional oil could be recovered from those fields with existing technology.

Assessment of Potential Additions to Conventional Oil and Gas Resources in Discovered Fields of the United States from Reserve Growth, 2012

Press Release & Publication
The U.S. Geological Survey estimated volumes of technically recoverable, conventional petroleum resources that have the potential to be added to reserves from reserve growth in 70 discovered oil and gas accumulations of the United States, excluding Federal offshore areas.

Assessment of Potential Additions to Conventional Oil and Gas Resources of the World (Outside the United States) from Reserve Growth

Press Release & Publication
The U.S. Geological Survey estimated volumes of technically recoverable, conventional petroleum resources resulting from reserve growth for discovered fields outside the United States that have reported in-place oil and gas volumes of 500 million barrels of oil equivalent or greater. The mean volumes were estimated at 665 billion barrels of crude oil, 1,429 trillion cubic feet of natural gas, and 16 billion barrels of natural gas liquids.

Assessment of remaining recoverable oil in selected major oil fields of the San Joaquin Basin

USGS Publication: Fact Sheet 2012–3050
The U.S. Geological Survey (USGS) recently completed an estimate of volumes of technically recoverable, conventional oil that could eventually be added to reserves in nine selected major oil fields in the San Joaquin Basin in central California. The mean total volume of potential oil reserves that might be added in the nine fields using improved oil-recovery technologies was estimated to be about 6.5 billion barrels of oil.

New U.S. Geological Survey Method for the Assessment of Reserve Growth

USGS Publication: Scientific Investigations Report 2011–5163
A new U.S. Geological Survey method was developed to assess the reserve-growth potential of technically recoverable crude oil and natural gas to be added to reserves under proven technology currently in practice within the trend or play, or which reasonably can be extrapolated from geologically similar trends or plays. This method currently is in use to assess potential additions to reserves in discovered fields of the United States.

Reserve Growth During Financial Volatility in a Technologically Challenging World

USGS Publication: Open-File Report 2010-1145
Reserve growth (growth-to-known) is the addition of oil and gas quantities to reported proved or proved-plus-probable reserves in discovered fields. The amount of reserve growth fluctuates through time with prevailing economic and technological conditions. Most reserve additions are the result of investment in field operations and in development technology.
