Plant-microbe interactions are considered to be important processes determining the efficiency of phytoremediation of petroleum pollution, however relatively little is known about how these interactions are influenced by petroleum pollution. In this experimental study using a microcosm approach, we examined how plant ecophysiological traits, soil nutrients and microbial activities were influenc...

Fuzzy C-means is a widely used clustering algorithm in data mining. Since traditional fuzzy C-means algorithms do not take spatial information into consideration, they often can’t effectively explore geographical data information. So in this paper, we design a Spatial Distance Weighted Fuzzy C-Means algorithm, named as SDWFCM, to deal with this problem. This algorithm can fully use spatial feat...

This paper presents the S-Chart framework, an approach for semantic image interpretation of line charts; and the InteliStrata system, an application for semantic interpretation of gamma ray profiles. The S-Chart framework is structured as a set of knowledge models and algorithms that can be instantiated to accomplish chart interpretation in all sorts of domains. The knowledge models are represe...

Decision analysis applied to petroleum field development is always strongly related to risk due to the uncertainties present in the process. Methodologies to quantify the impact of uncertainties are still not well established due to the amount of variables that have to be considered. The complete analysis usually depends on geological, economical and technological uncertainties that have differ...

The rock strata of Cretaceous sedimentary system represented by Aptian to Maastrichtian age occurs as isolated patches outcropping in the western margin of the Cauvery Basin bordering the Archaean granite and gneiss basement. The Cretaceous system is well known as “Cretaceous of Trichinopoly” containing diverse fauna and flora including dinosaur remains, commercially exploitable limestone, lign...

The characterization of fluid-transport properties of rocks is one of the most important, yet difficult, challenges of reservoir geophysics, but is essential for optimal development of hydrocarbon and geothermal reservoirs. Production of shale oil, shale gas, heavy oil and geothermal energy, as well as carbon-dioxide sequestration, are relatively recent developments where borehole fluid injecti...

The primary use of technical computing in the oil and gas industries is for seismic imaging of the earth’s subsurface, driven by the business need for making wellinformed drilling decisions during petroleum exploration and production. Since each oil/gas well in exploration areas costs several tens of millions of dollars, producing high-quality seismic images in a reasonable time can significant...

Mari Bugti hills and surroundings belong to Sulaiman basin (fragment of Gondwana) lies under the territory Balochistan, South Punjab North Sindh (Pakistan) but luckily have diverse marine terrestrial sediments varying in age from Triassic Recent, petroleum a large number mineral resources especially huge gypsum cement resources, numerous suitable anticlinal structures world-famous paleontology....

OBJECTIVE To test the tensile properties of knotted suture made of 4 different suture materials and exposed to petroleum gauze. STUDY DESIGN We tested the tensile strength of United States Pharmacopeia size 0-0 gauge polydioxanone, polyglyconate, glycolide/lactide copolymer, and silk when exposed to petroleum packing or saline. Suture materials were randomized, and knots were tied and then ev...

Since the end of previous century, the role of petroleum as a raw material of synthetic surfactant gradually deflated due to the reasons such as decreasing of the relative abundance of petroleum, leading to soared prices of petroleum and increasing of carbon dioxide emission by heavy utilization of petroleum. Instead, the industries concerning in the surfactants and detergents are focusing on t...
