A combination of subsurface borehole imaging data and drilling logs were used to characterize the fractures and lithology in 40 bedrock wells at the fractured-rock research site in the Mirror Lake area in Grafton County, New Hampshire. The purpose of the research was to determine whether subsurface lithology and fractures have an effect on the hydraulic conductivity of the crystalline-rock aqui...

Diminish of error ratio to expecting the lithology reservoir formation is considered as mean concerning geology nowadays. The aim research minimize wrong reading data extract facies by preparing using Interactive Petrophysics program (IP) make cluster analysis multi well logs data. Log Kirkuk oil field used in this included: Gamma ray (GR), sonic, neutron (N), bulk density (BD), Caliper and Res...

Abstract The Provincial Government of East Nusa Tenggara Eastern Indonesia has intended to construct a new regional landfill site in Pitay–Kupang, which would accommodate municipal waste two cities. Considering that environmental degradation sites been substantial issue for many developing cities Indonesia, this study evaluates the pre-determined on local scale based geology parameters. It empl...

The effects of geological conditionwere assessed on density of Soil Organic Carbon (SOC) and Nitrogen (N)in a sequence of hillslope landscape, derived from different lithology i.e. loess deposit, reworked loess, marl with mixed siltstone and shale, reddish brown clay deposits and older loess in the semiarid area of northern Iran. However, other factors can influence SOC and N density such as la...

Abstract The Upstream Cibeet sub-watershed is part of the Citarum watershed and with an area 69.35 km 2 . Hydrologically, upstream usually functions as a recharge area, its development should be geared towards land conservation erosion mitigation. Parameters rainfall, soil type texture, geology, lineament density, drainage geomorphology, cover are used in predicting most potential catchment are...

The Qiulitage structural belt in Tarim Basin has a large reservoir burial depth and complex geological conditions. Challenges such as ultra-depth, high temperature, pressure stress lead to significant problems related well control safety project efficiency. To solve these key technical issues that set barriers the process of exploration development, drilling technology via integration geology eng...

A Bayesian model coupled with a fuzzy neural network (BFNN) is developed to alleviate the difficulty of using geophysical data in lithology estimation when cross correlation between lithology and geophysical attributes is nonlinear. The prior estimate is inferred from borehole lithology measurements using indicator kriging based on spatial correlation, and the posterior estimate is obtained fro...
