Deterministic Earth Mechanical Science (Phil Holbrook, 2005)is modern physics that applies to the earth's sediments, sedimentary rocks, and SiAlic crust! This science is to the earth’s inner space what Newtonian mechanics is to the earth's surface, and outer space. This book also fills the physical-logical gap between Newtonian and Quantum mechanics. Natural mineral and fluid molecules are the working units of earth mechanics. Both books synthesize the mechanical laws of Newton, Coulomb, and Hooke. These intuitive men are justly honored by placement on the books' covers. Our earth’s slowly moving continental and oceanic plates are shown as one background which is explained by this synthesis of physical laws. The forces that we measure around an open borehole are shown on the other book's cover. Both mechanical explanations are supported by the same minimalist constitutive mechanical theory. Explaining earth and borehole mechanics extends Newton’s gravitational synthesis inward by accounting for the earth's internal forces. Gravity and the Effective Stress Theorem apply simultaneously in the earth's [mass-energy] synthesis. These two books are a significant advancement in physics through their revelation of molecular mechanics. Earth mechanics are completely scalable from molecular electron clouds which affect borehole walls in basins on drifting continental plates. These two books provide mathematically causal explanations for the earth's subsurface mechanical energy field. The Venn diagram below illustrates the overlapping characteristics of physical, and inorganic chemical laws with deterministic earth mechanics. These Deterministic Sciences spring from the same <symmetrically balanced> foundation that is illustrated in a central ellipse. The common pattern of the deterministic sciences will be revealed and explained in a newer book.The dashed lines extending outward symbolize direct algebraic connections to essential physical laws . The whole diagram represents physical realities that have been discovered in nature. The physical and conservation laws that compose the earth's minimum energy equation matrix in Normal Fault Regimes are shown at the bottom of this web page. The other two tectonic regime specific equation matrices are in "Deterministic Earth Mechanical Science".

The mechanics of the earth has both plastic and elastic limits. These limits are deterministically linked as shown below. Earth [stress/strain] reactions are usually near one of the two most recent limits. These hinge at the peak loading limb point. The slight differences from perfect linearity have additional physical explanations such as time lags. and strain properties. In both cases, Strain is a force balanced distance relationship that is governed by a mineral's molecular electron clouds.
Well planning requires earth load and fluid pressure information that depend directly on the earth's plastic compactional mechanical system. The elastic and Grain matrix compactional [stress/strain] limits are physically coupled as indicated by the panel immediately above. For an overview of earth constitutive mechanical systems limits, see earth mechanical systems limits.This is a quantum step in understanding the relationship between rock properties and their deterministic causes. Earth mechanics and pore pressure are co-dependant in accordance with [mass-energy] conservation and energy minimization principles! Drilling , setting casing, reservoir evaluation and compaction during hydrocarbon production are all carried out within the earth's mechanical field. The inter-dependencies within the earth's mechanical field can be used to engineering advantage Geomechanics, rock mechanics, and soil mechanics are parts of the same sediment-to-rock physical continuum. The energies in the earth's mechanical systems are transmitted through their respective molecular mineral and fluid electron clouds. A Constitutive Mechanical System Equation Matrix summary
Engineering forced-fits commonly bring their own special semantic confusions. Constitutive mechanical systems are an unambiguous natural basis for subsurface geology and engineering. The equation matrix shown above links previously accepted physical and conservation laws.M inimum energy mechanics are just that. A person that can perform simple mathematical operations can produce deterministically predictive answers. The energy expended in learning the inter-related laws is well worth the effort. Training is recommended for geologists and engineers that are or might be directly involved in earth mechanics. Good judgment in application comes from knowledge and experience. |
