Variable-Permeability Well-Testing Models and Pressure Response in Low-Permeability Reservoirs with non-Darcy Flow
This paper proposes the concept of variable-permeability effect and sets up the one-dimensional and two-dimensional non-Darcy well testing models. The finite difference algorithm is employed to solve the differential ...Universidad Nacional de Colombia Revistas electrónicas UN Earth Sciences Research Journal. -
Variación horaria de la humedad relativa del aire en el observatorio meteorológico nacional santafé de bogotá - colombia
Se determinan los valores medios horarios y la variación de la humedad relativa del aire para cada mes y el ano, con base en las observaciones horarias realizadas en la estación Observatorio Meteorológico Nacional-Ciudad ...Universidad Nacional de Colombia Revistas electrónicas UN Earth Sciences Research Journal. -
Vertebrates of the marília formation (late maastrichtian) from the peirópolis paleontological site: toward a better understanding
The Peirópolis paleontological site (Late Cretaceous, Maastrichtian) in Minas Gerais State, Brazil yielded an important assemblage of fossil vertebrates. The typical occurrence of South American widespread taxa in Peirópolis ...Universidad Nacional de Colombia Revistas electrónicas UN Earth Sciences Research Journal. -
Vichada meteorite impact effects from simulation of regional environmental consequences of a meteoroid impact on Earth
This study estimates the regional environmental consequences of the impactor extraterrestrial body that could produce the probable Vichada impact crater structure on the Vichada Plain, in Colombia, South America. This paper ...Universidad Nacional de Colombia Revistas electrónicas UN Earth Sciences Research Journal. -
Water temperature prediction in a subtropical subalpine lake using soft computing techniques
Lake water temperature is one of the key parameters in determining the ecological conditions within a lake, as it influences both chemical and biological processes. Therefore, accurate prediction of water temperature is ...Universidad Nacional de Colombia Revistas electrónicas UN Earth Sciences Research Journal. -
Wave equation datuming to correct topography effect on foothill seismic data
The current seismic processing applies Static Corrections to overcome the effects associated to rough topography, based in the assumption that velocity in near surface is lower than in the substratum, which force going up ...Universidad Nacional de Colombia Revistas electrónicas UN Earth Sciences Research Journal. -
X-ray color maps of the zoned garnets from silgará formation metamorphic rocks,santandermassif, eastern cordillera (colombia)
The metamorphic rocks of the Lower Paleozoic Silgará Formation of the Santander Massif, Eastern Cordillera (Colombia), were affected by a Barrovian-type metamorphism under low to high temperature and medium pressure ...Universidad Nacional de Colombia Revistas electrónicas UN Earth Sciences Research Journal. -
Zeolitisation of neogene sedimentary and pyroclastic rocks exposed in paipa (boyacá), in the colombian andes: simulating their natural formation conditions
The present study concerns the synthesis of zeolites from Neogene sedimentary and pyroclastic rocks exposed around the Sochagota Lake, Paipa (Boyacá). Two synthesis methods were used: conventional hydrothermal treatment ...Universidad Nacional de Colombia Revistas electrónicas UN Earth Sciences Research Journal. -
