In this study, eighteen compressional P-wave seismic refraction profiles survey was conducted on the western side of Gulf Suez, Egypt, to map bedrock topography, which is vital information in foundation pole placement and design for large factory construction. The configuration consists 10 metres geophone intervals (12 24 channels) with a total length 3150 length. wave velocity distribution rev...

Hydrothermal-reactor experiments were conducted to investigate the potential formation of chlorite and microquartz grain coatings on detrital quartz feldspar grains, understand their role in inhibiting (albite) overgrowths. Modern-day proximal distal unconsolidated sediment from Bute Inlet (British Columbia, Canada) with known amounts precursor clay content, used as starting material. The sampl...

Measurements of pore shapes from Scanning Electron Microscope (SEM) images for three sandstone samples (the Navajo Sandstone, the Weber Sandstone, and the Kayenta Sandstone) are compared to the aspect ratio spectra obtained from inverting laboratory velocity versus pressure data using the method of Cheng and Toksiiz (1979). The results indicate that the inversion method is in very good agreemen...

Nuclear magnetic resonance (NMR) relaxation-time measurements can provide critical information about the physiochemical properties of water-saturated media and are used often to characterize geologic materials. In unconsolidated sediments, the link between measured relaxation times and pore-scale properties can be complicated when diffusing water molecules couple the relaxation response of hete...

Research has been conducted into the diagenesis of the Luxembourg Sandstone. Literature studies were followed by a visit to the outcrop, after which thin sections were studied. The Luxembourg Sandstone Formation has been deposited in the Hettangian and Sinemurian, both lower Jurassic ages. A sea strait connecting the Northern German Basin and the Paris Basin was located in present day Luxembour...

Small-scale probe permeability measurements on differently oriented faces of highly compacted and quartz-cemented Viking Formation sandstones yield detailed permeability distributions that appear to be diagnostic of the grainand lamina-scale fabric of the samples. Permeability anisotropy of a single ‘structureless'-appearing sample is low, reflected by a kV / kH-ratio of 0.7; corresponding k-di...

Abstract Deformation bands (DB) are known to influence porosity and permeability in sandstones. This study aims predict the occurrence of DB quantify their impact on reservoir properties based field measurements steeply dipping limb a kilometer-scale fold Yasamal Valley, western South Caspian Basin. An integrated approach characterizing effect included natural gamma radioactivity using portable...

The production of heavy oil at Dong Do field located in CuuLong basin is a success the application advanced technologies. marginal project Vietnam, so its development requires to overcome several challenges, such as high water-cut from early stage, highly unconsolidated sandstone reservoir, flow assurance problems sour and viscous crude oil, power artificial lift system, complex treatment topsi...

The use of gravity data has demonstrated capability for monitoring lithological changes on a large scale as consequence differentiating basement and sedimentary buried valleys. Gravity anomalies are associated with lateral contrasts in density therefore deformation by faulting or folding will be manifested if accompanied changes, otherwise, the vice versa is true. study’s objective to evaluate ...

Abstract In oil and gas industry, sand can be carried with gas, when producing from unconsolidated sandstone reservoirs. The existence of particles fluids flow lead to severe damages production system’s components. Therefore, control techniques are needed prevent potential damages. Standalone screens (SAS) widely used because they provide reliable low cost complexity. However, SAS application b...
