A reactive fluid dissolving the surface of a uniform fracture will trigger an instability in the dissolution front, leading to spontaneous formation of pronounced well-spaced channels in the surrounding rock matrix. Although the underlying mechanism is similar to the wormhole instability in porous rocks there are significant differences in the physics, due to the absence of a steadily propagati...

Rock fracture and its failure with time due to external forces other factors such as fluids, temperature have always been a major concern in rock engineering construction. Based on thermodynamics theory of solid physics, authors propose an energy criterion for rheological rock, which considers two effects: (1) dissipation reduces strength rock; (2) confining pressure increases rock. Subsequentl...

Stochastic models that account for sudden, unforeseeable events play a crucial role in many different fields such as finance, economics, biology, chemistry, physics and so on. That kind of stochastic problems can be modeled by stochastic differential equations driven by jumpdiffusion processes. In addition, there are situations, where a stochastic model is based on stochastic differential equat...

Abstract Pre-stack seismic inversion based on sensitive elastic parameters is critical in reservoir lithology prediction and geofluid identification. The ability of a single attribute to identify depends its sufficient sensitivity distinguish the target from surrounding sediments. In general, high-dimensional data space composed multiple attributes more conducive describing characteristics. The...

Turbidite systems are complex heterogeneous siliciclastic deposits calling for a new approach to geophysical and geostatistical reservoir characterization. The aim of this paper is to demonstrate the integration of seismic amplitude and rock physics data into realistic geological scenarios using a novel geostatistical approach. Avseth (2000, 2001 with others) presented an integrated rock physic...
