A novel associative model was developed to predict petroleum well performance after remedial treatments. This application is of interest, particularly for non-uniform oilfields such as naturally fractured ones, and can be used in decision support systems for water control or candidate well selection. The model is based on the Gamma classifier, a supervised pattern recognition model for mining p...

The toxicology of synthetic chemicals is compared to that of natural chemicals, which represent the vast bulk of the chemicals to which humans are exposed. It is argued that animals have a broad array of inducible general defenses to combat the changing array of toxic chemicals in plant food (nature's pesticides) and that these defenses are effective against both natural and synthetic toxins. S...

Abstract Oil and gas recovery may cause formation damage during drilling, completion, production phases. As a result of fundamental chemical, thermal, mechanical, biological interactions, can occur due to impairment permeability porosity, causing undesirable operational economic problem. The fluid-rock interactions resulting from oilfield chemicals injection enhanced oil (EOR) such as chemical ...

Abstract The Gaoshangpu block of Jidong Oilfield is a hot for increasing production and storage in Oilfield. High-quality efficient drilling completion can shorten the operation time have huge economic social benefits. Aiming at problems large well depth, complex geological conditions, poor stratum drillability, low machinery efficiency, long cycle Oilfield, this paper optimizes its drill bits,...

A study was carried out and an analysis made of the features operation oilfield control center. The technical solutions for management power supply facilities oil field are considered

background: one of the most important environmental risk factors for kidney cancer is occupational exposure to chemical carcinogens. since the isfahan province is one of the major industrial centers in iran and various chemical industries operating in the province, this study was conducted to determine the association of kidney cancer and occupation. methods: this case-control study was conduct...
