The need to identify the major parameter with an overwhelming impact on estimated hydrocarbon volume has been a challenge for stakeholders in oil and gas industry. To address this challenge, investigation of depositional facies petrophysical parameters was carried out field located within Niger Delta using 3D geologic models. Different modeling techniques were employed study; each technique pro...

Sarvak Formation as the oil reservoir with the most hydrocarbon potential in Yaran oil field is of special importance. The present research was conducted to study the reservoir parameters of this Formation. For this purpose, petro-physical crude data was first prepared and using the Geolog6.7 software, a petro physical plot was drawn. Afterward, petro-physical properties of reservoir were done ...

Reservoir characterization of W-field, onshore Niger Delta was carried out using petrophysical evaluation well logs. Three reservoir sand intervals (A, B, C) were identified and correlated across four wells (W1, W2, W3, W4) in W-field the gamma ray, while fluid identification each achieved resistivity log. The C interval selected utilized for interpretation penetrated at depths 11741-11945ft, 1...

Hydraulic fracturing and matrix stimulation are two major methods of the reservoir stimulation. Hydraulic fracturing, which is the newest technique and technically more complex, is very useful in low permeability reservoirs. Although it has been used widely in hydrocarbon production wells, it is a new method in Iran. In this paper, the effect of sufficient barrier layers on hydraulic fracturing...

The metabolism of toluene by natural populations of marine bacteria, stored to enhance their activity, gave hyperbolic kinetics with saturation at only K, = 0.6 to 3.4 pg liter-‘. Similarly Kl in fresh seawater was 0.26 pg toluene liter-‘. Freshly collected populations could be moderately active toward toluene, affinity azA = 1.1-37.5 liters g-cells-l h-l. These moderate affinities taken togeth...

In this paper, I introduce a new mathematical model of the IP effect based on the effective-medium theory, which provides a unified mathematical method to study heterogeneity, multi-phase structure, and polarizability of rocks. The geoelectrical parameters of a new composite conductivity model are determined by the intrinsic petrophysical and geometrical characteristics of composite media: mine...

In most envisioned applications, the full utilization of a graphene-carbon nanotube (CNT) construct requires maintaining the integrity of the graphene layer during the CNT growth step. In this work, we exhibit an approach toward controlled CNT growth atop graphene substrates where the reaction equilibrium between the source hydrocarbon decomposition and carbon saturation into and precipitation ...

Determining saturation and pore pressure is relevant for hydrocarbon production as well natural gas [Formula: see text] storage. In this context, seismic methods provide spatially distributed data used to determine fluid migration. A method developed that allows the determination of reservoir from data, more accurately rock-physics attributes velocity, attenuation, density. Two models based on ...
