There are the results of a study factors determining formation and changes in filtration properties heap leaching stack formed from pelletized poor sandy-clay ores. An analysis methods investigation ore material for different stages plots functioning is carried out. Influence segregation process during dumping on zones with very permeability parameters has been established by experimental works...

El Mirador de los Túneles is a tube-shaped volcanic cave with sinuous structure in the Galápagos Islands formed due to cooled near-surface lava flows. Since this natural formation considered tourist site, large number of people frequent it daily; however, its safety conditions have not yet been defined by comprehensive geotechnical study. In research, stability analysis was carried out combinin...

The problem of roadway support in swelling soft rock was one of the challenging problems during mining. For most geological conditions, combinations of two or more supporting approaches could meet the requirements of most roadways; however, in extremely swelling soft rock, combined approaches even could not control large deformations. The purpose of this work was to probe the roadway deformatio...

Hydrocarbon production modifies the stress conditions in the subsurface and changes the model parameters previously estimated from the prospect. The capability to remotely monitor the changes in the reservoir using seismic data has strategic importance since it allows us to infer fluid movement and evolution of stress conditions, which are key factors to enhance recovery and reduce uncertainty ...

One of the costliest problems facing production hydrocarbons in unconsolidated sandstone reservoirs is sand once hydrocarbon starts. The sanding start prediction model very important to decide on control future, including whether or when should be used. This research developed an easy-to-use Computer program determine beginning sites driven area. based estimating critical pressure drop that occ...

Abstract. Realistic modelling of tightly coupled hydro-geomechanical processes is relevant for the assessment many hydrological and geotechnical applications. Such occur in geologic formations are influenced by natural heterogeneity. Current numerical libraries offer capabilities physics couplings that have proven to be valuable fields like gas storage, rock fracturing Earth resources extractio...
