Further Discussion on Pressure Drawdown and Buildup in the Presence of Radial Discontinuities
By H. K. VAN POOLLEEN, W. Hurst, H. C. Bixel
In an earlier publication* I showed the development of the instantaneous point source solution for a well producing at a constant rate at the center of a system of two radial, adjoining sands of diffe

Reservoir Engineering - General - Some Theoretical Aspects of Underground Combustion in Segregated Oil Reservoirs
By B. S. Gottfried
This paper is concerned with possible transport mechanisms which occur during segregated burning (i.e., burning in an oil reservoir in which the oil-bearing formation is overlain by a "clean" porous z

Technical Notes - Energy Requirements in Size Reduction
By Y. Oka, H. Majima
When a rock particle is subjected to an external force, internal stresses and deformations are experienced by the particle. Assuming that the breakage of a rock is mainly due to tensile stresses gener

Laws Of Rock Behavior In The Earth's Crust
By Neville J. Price
In order that the reader may not be misled, I feel it necessary to comment upon the title of this paper. "Laws of Rock Behavior," one may take as being part of the all-embracing "Law of Nature" and th

Hardening Effects Resulting From The Formation Of Both A Precipitate Phase And A Superlattice
By M. R. Pickus, I. W. Pickus
ORDINARILY age-hardening is thought of as being associated with a limited solubility of one metal in another. Much less has been written about the type of age-hardening that attends the formation of s
