Abstract Proppant is one of the major elements a hydraulic fracture process that can influence productivity an oil or gas well. The permeability propped may be determined through laboratory measurements, utilizing experimental relationships, using analytical methods. All methods have their advantages and disadvantages, this study attempts to offers solution combines various achieve practical so...

Interwell connectivity, an important element in reservoir characterization, especially for water flooding, is used to make decisions better oil production. The existing methods literature directly use related data of wells infer interwell but they ignore the influence between different wells. connection one well more than two (as often true field pattern) will impact accuracy connectivity analy...

This paper reviews the current research on the speciation and determination of mercury by various analytical instruments such as, atomic absorption spectrometer (AAS), voltammeter, inductively coupled plasma optical emission spectrometer (ICP-OES), ICP-atomic emission spectrometer (AES), ICP-mass spectrometer (MS), atomic fluorescence spectrometer (AFS), spectrophotometer, spectrofluorometer, a...

This paper presents a facile and selective method for the determination of the pharmaceutical compound nafronyl using heavy atom induced room temperature phosphorimetry (HAI-RTP) as analytical technique. The determination was performed in potassium iodide 1.6 M and sodium sulphite 0.002 M at a measurement temperature of 20 degrees C. The phosphorescence intensity was then measured at lambda(exc...

Purpose: To develop a simple yet sensitive, reliable and robust method for qualitative determination of cocaine and a series of its tropane metabolites in biological samples (blood, urine, etc.). The method should be optimized for routine forensic expertise in analytical toxicology. Material/Methods: Gas chromatography coupled with mass spectrometry (GC-MS) has been used as the method for analy...
