The X field is located in the southwestern part of block NX89 Kentan Basin Libya. This produced from Hailan multilayer consolidated sandstone with moderate rock property and a relatively low energy supplying. reserve subsurface sources declining years. Therefore, techniques were combined to achieve optimization increase hydrocarbon recovery. In order understand formation reservoir facilitate oi...

In mature multilayer gas reservoirs, it is a common problem to evaluate whether potential reservoir still productive after casing. Monitoring of unproduced or developing formations can guide production action plans. Intervention in unperforated zones with high density increase production, whereas intervention low uneconomical. An RPM instrument stratum model was established by using the Monte C...

We extend the concept of graph isomorphisms to multilayer networks, and we identify multiple types of isomorphisms. For example, in multilayer networks with a single “aspect” (i.e., type of layering), permuting vertex labels, layer labels, and both of types of layers each yield a different type of isomorphism. We discuss how multilayer network isomorphisms naturally lead to defining isomorphism...

Petro physics, rock physics and multi-attribute analysis have been employed in an integrated approach to delineate porosity variation across Tamag Field of Niger Delta Basin. Gamma and resistivity logs were employed to identify sand bodies and correlated across the field. Petro physical analysis was undertaken. Rock physics modelling and multi-attribute analysis were carried out. Two hydrocarbo...

The method for studying the adsorption characteristics of coal seam has density method, mercury-pressing and method. In this experiment, a low temperature nitrogen was used to determine relative data coal-like porosity by using surface area meter TriStarI3020 arrangement molecules on samples. Before beginning samples Yang dong reservoir were prepared, weighed, devaporation time set at 2h, kept ...

We designed multilayer wavelength-selective reflector films by stacking thin-films of transparent polymer. The optimum structure of the multilayer is determined using a combination of characteristic matrix method and a version of genetic algorithm. Such multilayer films can be used in LCD devices to enhance the color saturation of the display. key words: optical design, multilayer, color enhanc...

Porosity is considered as an important petrophysical parameter in characterizing reservoirs, calculating in-situ oil reserves, and production evaluation. Nowadays, using intelligent techniques has become a popular method for porosity estimation. Support vector machine (SVM) a new intelligent method with a great generalization potential of modeling non-linear relationships has been introduced fo...

Extremely anisotropic metal-dielectric multilayer metamaterials are designed to have the effective permittivity tensor of a transverse component (parallel to the interfaces of the multilayer) with zero real part and a longitudinal component (normal to the interfaces of the multilayer) with ultra-large imaginary part at the same wavelength, including the optical nonlocality analysis based on the...

Litho-facies classification is an essential task in characterizing the complex reservoirs petroleum exploration and subsequent field development. The lithofacies at borehole locations detailed but lacks providing larger coverage areas. acquired 3D seismic data provides global for studying reservoir facies heterogeneities study area. This applies six supervised machine learning techniques (Rando...
