The oilfield soil was contaminated for years by large quantities of aged oil sludge generated in the petroleum industry. In this study, physicochemical properties, contents of main pollutants, and fungal diversity of the aged oil sludge-contaminated soil were analyzed. Results revealed that aged oil sludge significantly changed physical and chemical properties of the receiving soil and increased the contents of main pollutants (petroleum hydrocarbons and heavy metals) in soil. Meanwhile, the internal transcribed spacer (ITS) sequencing by Illumina Miseq platform at each taxonomic level demonstrated that the toxicological effect of oil pollutants obviously influenced the fungal diversity and community structure in soil. Moreover, it was found that the presence of three genera (Cephalotheca, Lecanicillium, and Septoriella) appeared in aged oil sludge-contaminated soil. And oil pollutants promoted the growth of certain genera in Ascomycota (70.83%) and Basidiomycota (10.78%), such as Venturia, Alternaria, and Piloderma. Nevertheless, the growth of Mortierella (9.16%), Emericella (6.02%), and Bjerkandera (0.00%) was intensively limited. This study would aid thorough understanding of microbial diversity in oil-contaminated soil and thus provide new point of view to soil bioremediation.

Oil sludge resulting from crude oil processing in the petroleum industry could have a negative impact on the environment. Oil sludge could also be classified as hazardous waste and able to damage the environment and human health. Therefore, it was necessary to solve this issues. Oil sludge hydrocarbon utilizing to get higher value was one of solution offered by these research. In the utilization process, filtration method was used at first procedure and followed by diesel mixing at ratio 1:0.1, 1:0.2, 1:0.3, 1:0.4, and 1:0.5. The mixture was then analyzed for several parameters such as heating value, moisture content, ash content, and flashpoint. The results of heating values ranging from 5.966 calories/ gram to 7.210 calories/ gram, the flashpoint was from 38 ⁰C to 76 ⁰C, the water content was from 51.89% to 54.52%, the ash content was from 12.3% to 18.03%. The results showed that utilization of oil sludge could be used as liquid fuel alternative energy.  Keywords: oil sludge, energy alternative, liquid fuel

Rare-earth phosphates are of particular interest because of their catalytic properties associated with the hydrolysis of many aromatic chlorides in the petroleum industry. Lanthanum phosphates (LaPO4) which have been doped with small amounts of copper have shown increased catalytic activity (1). However the physical and chemical characteristics of the samples leading to good catalytic activity are not known.Many catalysts are amorphous and thus do not easily lend themselves to methods of investigation which would include electron microscopy. However, the LaPO4, crystals are quite suitable samples for high resolution techniques.The samples used were obtained from William L. Kehl of Gulf Research and Development Company. The electron microscopy was carried out on a JEOL JEM-100B which had been modified for high resolution microscopy (2). Standard high resolution techniques were employed. Three different sample types were observed: 669A-1-5-7 (poor catalyst), H-L-2 (good catalyst) and 27-011 (good catalyst).
