"Pore Pressure through Earth Mechanical Systems" is a constitutive field theory that relates compactional strain to composition in the earth. Minerals and fluids are the dominant natural molecular matter in the earth. [Mass-energy] and [stress/strain] conservation are shown to be algebraically equivalent in a closed mathematical form in the earth. Relatively few measurements are needed to describe the earth's mechanical field. The physical basis for this theory is universal i.e. [forcebalance] under [mass-energy] conserved boundary conditions. Earth mechanics theory satisfies Niels Bohr's "correspondence principle". It simultaneously explains both the accepted and the newer theories. The earth's "molecular mechanics" theory uses Newtonian mechanics as a limit as did Niels Bohr's when he revealed Quantum mechanics. The earth's elastic and plastic mechanical limits are connected to each other by their common (mineral-fluid) constituents. Earth mechanics depends directly to the laws of Newton, Coulomb, and Hooke. Earth mechanics theory is firmly rooted in fundamental mechanics between Newton's and Bohr's. Subsurface engineering involves a quantitative balance between human regulated forces in a well and those that are drilled into the earth. Pressures and stresses in the earth that were derived from empirical forced-fits were treated with a great deal of skepticism and given large engineering uncertainties. Earth Mechanical Systems present a new [closed-form] analytical design approach to drilling and subsurface engineering. Mechanical systems tend toward the minimum energy state. Each of these [force-balanced] equation systems is in a [closed-mathematical-form]. The earth is composed almost entirely of minerals and fluid. This [closed-form] synthesis relates physical laws to matter in the earth's sedimentary crust. Contact phil@Force-Balanced.net for general information or to order this book.

For book collectors; this book is an earth domain parallel to Newton's Principia. The energy of gravity acts in concert with electrostatic energy in the earth's sedimentary crust. The book's subtitle, "The force-balanced physics of the earth's sedimentary crust", describes the resulting scientific advancement.

Author Biography
Scientist-engineer's biography Phil Holbrook received his Ph.D. in Geology from Penn State in 1973. His career in the oil industry involved exploration operations but mostly involved mathematically oriented research and development. He worked successively for Gulf Science and Technology 1973 and Exxon Production Research 1978. He joined Sperry-Sun Drilling Services in 1984 and began work on what is still the only mechanically representative pore pressure and fracture pressure prediction methodology. He developed, and successfully applied a computer program and methodology using over 300 wells in over a dozen basins worldwide. Earth mechanics is a force balanced constitutive mechanical theory that answers many questions including "How are stresses transmitted from the mantle to freshly deposited sediments through the earth's sedimentary crust?" The answers are all closed-form minimum energy mathematical expressions. The "first fundamental in situ [stress/strain] relationship" is a scalar plastic (force and material) balanced relationship that involves yielding over near infinite time. It is average mineral specific. Thus the earth is found to have both absolute and power-law symmetry.
