The rheological properties of four different Kuwaiti crude oils in the presence of polyacrylamide (PAA) were investigated. PAA was varied at three different concentrations of 25, 50, and 75 ppm to study the viscoelastic properties in the untreated samples. Four different temperatures (25, 30, 35, and 40 °C) were used to evaluate different viscoelastic parameters of the treated and untreated Kuw...

The study has been carried out with two broad objectives – to observe the effect of crude oil contamination on consolidation properties of soil and to predict the change in the properties in the form of mathematical correlation. The properties studied here are co efficient of compression (Cv) and compression index (Cc). Four types of naturally available soil (CH, CL, CI and SC) collected from d...

Crude oil blending is an important unit operation in petroleum refining industry. A good model for the blending system is beneficial for supervision operation, prediction of the export petroleum quality and realizing model-based optimal control. Since the blending cannot follow the ideal mixing rule in practice, we propose a static neural network to approximate the blending properties. By the d...

Investigations were made on the effect of Bonny light crude oil on stem sprouting of Talinum triangulare. Five concentrations of crude oil viz, 2.5mls, 5.0ml, 7.5ml, 10.0mls and 12ml were applied to 7kg of dry soil in perforated polyethene bags. The experiment was carried out on a completely randomized design (CRD) and replicated 6 times. Data on the number of days to sprouting, number of branc...

The use of laser induced fluorescence (LIF) spectroscopy to characterize crude oil has privileges compared to conventional techniques in terms of reducing the size of sample, rapidity of measurements, high sensitivity and simplicity of sample handling and possibility of in situ measurements. The fluorescence radiation emitted from crude oil is the result of the interaction between the aromatic ...

The toxicity resulting from exposure to oil droplets in marine fish embryos and larvae is still subject for debate. The most detailed studies have investigated the effects of water-dissolved components of crude oil in water accommodated fractions (WAFs) that lack bulk oil droplets. Although exposure to dissolved petroleum compounds alone is sufficient to cause the characteristic developmental t...

Accurate estimation of reservoirs fluid properties, as vital tools of reservoir behavior simulation and reservoir economic investigations, seems to be necessary. In this study, two important properties of crude oil, bubble point pressure (Pb) and formation volume factor (Bob), were modelled on the basis of a number of basic oil properties: temperature, gas solubility, oil API gravity and gas sp...
