Capillary Pressures in Stratigraphic Traps
Capillary pressures between oil and water in rock pores are responsible for trapping oil, and the height of oil column, zo, in a reservoir may be calculated from the Hobson equation modified asExpand
Primary Migration by Oil-Generation Microfracturing in Low-Permeability Source Rocks: Application to the Austin Chalk, Texas
Fracturing of low-permeability source rocks is induced by pore-pressure changes caused by the conversion of organic matter to less dense fluids (oil and gas); these fractures increase theExpand
Method for Determining Permeability from Reservoir Rock Properties
ABSTRACT Porosity and permeability of reservoir sandstones can be related to the primary rock properties of composition, texture, and packing. Permeability is assumed to be largely a function ofExpand
FRANCONIA FORMATION OF MINNESOTA AND WISCONSIN
The Upper Cambrian Franconia formation in southeast Minnesota and west-central Wisconsin consists of glauconitic, quartzose sandstones that average 175 feet in thickness. Previous subdivision of theExpand
Estimating organic maturity from well logs, Upper Cretaceous Austin Chalk, Texas Gulf coast
ABSTRACT The Austin Chalk is both a source rock for oil and a fractured reservoir, and the evaluation of its organic maturity from well logs could be an aid to exploration and production. GeochemicalExpand
Mountain Flank Thrusting in Rocky Mountain Foreland, Wyoming and Colorado
The principal mountain ranges of the Wyoming and Colorado foreland were raised asymmetrically by Laramide uplift which began in latest Cretaceous time as dominantly vertical movement along arcuateExpand
Hydrodynamic Effects on Mission Canyon (Mississippian) Oil Accumulations, Billings Nose Area, North Dakota
Mission Canyon oil production on the south flank of the Williston basin provides an example of an area in the mature stage of exploration that shows significant hydrodynamic effects on oilExpand
Trilobites from the Peerless and Manitou formations, Colorado
An Upper Cambrian fauna of Franconian age is present in the Peerless formation in a unit of sandy glauconitic dolomite that formerly was called the Ute Pass dolomite. This fauna includes species ofExpand
Recognition of Barrier Environments
The vertical succession of sedimentary structures and textures at Galveston Barrier Island, Texas, is identical with vertical successions in two ancient barrier complexes, one in the Lower CretaceousExpand
Trapping capacity of faults in the Eocene Yegua Formation, East Sour Lake field, southeast Texas
The properties of a sheared zone in the Eocene Yegua Formation were investigated to evaluate the trapping capacity of faults. An 11-m core of Yegua sandstone at a depth of 3029 m shows highly shearedExpand
