Petroleum Extraction

The development of petroleum extraction and transport technology does not ensure complete isolation of these substances from the natural environment. This problem is exacerbated by the location of mining equipment on the sea shelf and the fact that numerous submarine pipelines, tankers and handling terminals can also emit oil pollution. Therefore, the possibility of detecting oil dispersed in the water is particularly important. This paper reports the efforts to identify methods of characterization of the water containing the crude oil emulsion in a very low concentration (a few to several tens of ppm). Due to this, the effect of emulsion concentration on the possibility of its objective characterization using synchronous fluorescence spectra was studied. The similarity of spectra at various oil concentrations was analysed. It has been shown that the stabilization of the shape of synchronous fluorescence spectra occurs at relatively low oil concentrations.

Developing scientific practices and procedures for finding the characteristics of various crude oils from different geological sources based on fluorescence spectra fingerprints would be beneficial to the petroleum industry. Laser-Induced Fluorescence (LIF) has gained relevance worldwide because of its advantages in crude oil analysis. Presently, the use of this technique in the characterization of crude oils from the oil fields in Ghana has not been studied. The study employed the LIF technique to determine some physical qualities of crude oils from Jubilee Oil Field, Tweneboa Enyenra Ntomme (TEN) Oil Field and Saltpond Oil Field. Specifically, this study used multivariate analysis methods to link the spectral signatures of the crude oils to their properties for identification and classification. The LIF technique was applied on four crude oil samples. Fluorescence spectra were obtained using a continuous wave 405.0 nm laser. The excitation source revealed five (5) peak wavelengths after deconvolution. Using Principal Component Analysis (PCA), Linear Discriminant Analysis (LDA) and Hierarchical Cluster Analysis (HCA), the crude oil samples were classified accurately.

Analysis of environmental materials is very important for the environmental assessment, especially for the crude oil-contaminated water. This paper investigated the degradation of crude oil in the polluted water under the irradiation of UV light, and used the UV absorption, synchronous fluorescence spectra and gas chromatograph to analysis the changes of the environmental materials in the crude oil polluted water during the irradiation. All of the absorbance substances, fluorescent substances and saturated hydrocarbons in the crude oil polluted water decreased with the UV light irradiation. In addition, the dissolved organic matters in the seawater had significant influence on the photodegradation of crude oil.

We are investigating by Raman microprobe measurements the superconducting and related phases in the LnBa2Cu3O7-x (for x=0 to 1) system where yttrium has been replaced by several of the lanthanide (Ln = Nd,Sm,Eu,Ho,Er) elements. The aim is to relate the observed optical spectra (Raman and fluorescence) to the compositional and structural properties of these solids as part of comprehensive materials characterization. The results are correlated with the methods of synthesis, the processing techniques of these materials, and their superconducting properties. Of relevance is the substitutional chemistry of these isostructural systems, the differences in the spectra, and their microanalytical usefulness for the detection of impurity phases, and the assessment of compositional homogeneity. The Raman spectra of most of these compounds are well understood from accounts in the literature.The materials examined here are mostly ceramic powders prepared by conventional solid state reaction techniques. The bulk samples are of nominally single-phase composition as determined by x-ray diffraction.
