Modeling of Subsidence and Reservoir Compaction under Waterflood Operations
(American Society of Civil Engineers, 2004)A full-field, three-dimensional (3D) computer model has been developed to numerically simulate reservoir compaction and surface subsidence for a weak, water-sensitive, hydrocarbon reservoir during field-wide water-injection ... -
Numerical Study of the Bearing Behavior of Piled Rafts
(American Society of Civil Engineers, 2004)Based on a numerical study by means of three-dimensional finite-element analysis, this paper discusses investigations of the bearing behavior of piled rafts in -
Multiple Fracture Propagation Model for a Three-Dimensional Hydraulic Fracturing Simulator
(American Society of Civil Engineers, 2004)Multiple nonplanar hydraulically induced fractures are often observed or assumed to exist in well stimulation sites of petroleum and geothermal reservoirs. Although such multiple and nonplanar features of the fractures ... -
Radioactive Marker Measurements in Heterogeneous Reservoirs: Numerical Study
(American Society of Civil Engineers, 2004)A numerical study is performed to simulate the vertical deformation of a depth interval representing a marker spacing (10.5 m) located in a deep heterogeneous sedimentary reservoir. Realistic lithostratigraphic sequences ... -

Lateral Resistance of Short Single Piles and Pile Groups Located Near Slopes
(American Society of Civil Engineers, 2004)Many transmission towers, high-rise buildings, and bridges are constructed near steep slopes and are supported by large-diameter piles. These structures may be subjected to large lateral loads, such as violent winds and ... -
Effect of Nonlinear Soil Behavior on Inelastic Seismic Response of a Structure
(American Society of Civil Engineers, 2004)The characteristics of the earthquake motions at the base of a structure are affected by the properties of the underlying soil through the soil amplification and soil–structure interaction phenomena. In this paper the ... -
Effective Stress in Unsaturated Soils: Review with New Evidence
(American Society of Civil Engineers, 2004)The application of the effective stress principle to unsaturated soils is critically reviewed, and the reasons underlying the difficulties in previous investigations of the effective stress in unsaturated soils are ... -
Plasticity Model for Stress-Release Induced Damage
(American Society of Civil Engineers, 2004)Stress-release damage in rocks may result in a permanent alteration of the rock properties, which has to be quantified and modeled in order to describe the in situ behavior of the rock based on tests from core specimens. ... -
Discrete Element Modeling Applied to Laboratory Simulation of Near-Wellbore Mechanics
