The discrete fracture networks (DFN) have become indispensable tools for geomechanical modelling of jointed rock masses. technology creates a three-dimensional (3D) representation geometry used in the construction surface and subsurface engineering projects mining, civil engineering, fracturing reservoir oil gas industry. approach depends on accuracy data obtained during site investigation to c...

This paper documents our effort to use a fully coupled hydro-geomechanical numerical test bed to study using low hydraulic pressure to stimulate geothermal reservoirs with existing fracture network. In this low pressure stimulation strategy, fluid pressure is lower than the minimum in situ compressive stress, so the fractures are not completely open but permeability improvement can be achieved ...

Particle Scale Reservoir Mechanics — This paper summarizes some developments and applications of discrete particle modelling based on the commercial code PFC (Particle Flow Code). The following examples with relevance to geomechanical reservoir behaviour are described: – Numerical and experimental results are shown illustrating nonlinear evolution of depletion-induced compaction and stress path...

margins contain vast reserves of gas hydrate, a frozen form of natural gas that is embedded in cold, near-seafloor strata. Published estimates suggest that the energy represented by gas hydrate may exceed the energy available from conventional fossil fuel by a factor of 2 or more. Understanding marine hydrate systems has become critical for long-term worldwide energy planning. Groups in several...

Geomechanical characterization plays a key role in optimizing the stimulation treatment of tight reservoir formations. Petrophysical models help classify rock as conventional or unconventional type and determine hydrocarbon-saturated zones. petrophysical are fundamentally based on well-log data that provide reliable high-resolution information, used to various relationships between measured bor...

Geotechnical models developed during the planning stages of open pit mines are three-dimensional so as to capture spatial variation in lithological, structural, hydrogeological, and geomechanical conditions. Geological that describe lithological structural (faulting folding) characteristics a deposit always 3D. Likewise, boreholes piezometers used develop properties groundwater drilled at offse...
