Identification and assessment of remaining oil resources in the Frio fluvial-deltaic sandstone play, south Texas Identification and assessment of remaining oil resources in the Frio fluvial-deltaic sandstone play, south Texas 1995

The Frio Fluvial-Deltaic Sandstone (Vicksburg Fault Zone) play of South Texas has produced nearly 1 billion barrels (Bbbl) of oil since field development began in the 1940's.

Holtz, M.H., McRae, L.E. Report of Investigations Bureau of Economic Geology
Depositional Environments of Unstable Shelf-Margin Deltas of the Oligocene Vicksburg Formation, McAllen Ranch Field, South Texas Depositional Environments of Unstable Shelf-Margin Deltas of the Oligocene Vicksburg Formation, McAllen Ranch Field, South Texas 1994

Cores and supporting petrophysical data from 20 wells in McAllen Ranch field were analyzed.

Langford, R.P., Combes, J.M. Report of Investigations Bureau of Economic Geology
Quantifying secondary gas resources in fluvial/deltaic reservoirs: a case history from Stratton field, south Texas Quantifying secondary gas resources in fluvial/deltaic reservoirs: a case history from Stratton field, south Texas 1994

Geologic and engineering studies were conducted within fluvial/deltaic strata of a mature South Texas field to determine the impact of reservoir compartmentalization on secondary gas recovery. Stratton is one of several mature South Texas fields containing fluvial and deltaic gas reservoirs.

Levey, R.A., Finley, R.J., Sippel, M.A. Report of Investigations Bureau of Economic Geology
Gas reservoir quality variations and implications for resource development, Frio Formation, south Texas: examples from Seeligson and Stratton fields Gas reservoir quality variations and implications for resource development, Frio Formation, south Texas: examples from Seeligson and Stratton fields 1993

Discovery of volcanic glass detritus in fluvial deposits of the middle Frio Formation (Seeligson and Stratton fields) of South Texas has resulted in a new classification of reservoir types (type I and type II) within this formation.

Depositional and ground-water flow systems of the Carrizo - Upper Wilcox, south Texas Depositional and ground-water flow systems of the Carrizo - Upper Wilcox, south Texas 1988

In the Rio Grande Embayment of South Texas, the Carrizo Formation (lower Eocene) consists of two sand-rich fluvial depositional systems that grade basinward into several deltaic complexes within the upper part of the Wilcox Group.

Hamlin, H.S. Report of Investigations Bureau of Economic Geology
Depositional framework, hydrostratigraphy, and uranium mineralization of the Oakville Sandstone (Miocene), Texas coastal plain Depositional framework, hydrostratigraphy, and uranium mineralization of the Oakville Sandstone (Miocene), Texas coastal plain 1982

The Oakville Sandstone (Miocene) of the Texas Coastal Plain comprises a major sand-rich fluvial system composed of deposits of several major and minor rivers that originated within Texas and surrounding states.

Geochemistry of ground water in the Miocene Oakville Sandstone -- a major aquifer and uranium host of the Texas coastal plain Geochemistry of ground water in the Miocene Oakville Sandstone -- a major aquifer and uranium host of the Texas coastal plain 1982

The Oakville Sandstone is a major aquifer and a major host of uranium deposits in the Texas Coastal Plain.

Henry, C.D., Galloway, W.E., Smith, G.E., Ho, C.L., Morton, J.P., Gluck, J.K. Report of Investigations Bureau of Economic Geology
Regional hydrodynamics and hydrochemistry of the uranium-bearing Oakville aquifer (Miocene) of south Texas Regional hydrodynamics and hydrochemistry of the uranium-bearing Oakville aquifer (Miocene) of south Texas 1982

The Oakville Formation consists of sediments deposited by several major fluvial systems that traversed the Texas Coastal Plain during the Miocene Epoch.
