Currently, frequent oil spill accidents caused by transportation, storage, and usage may lead to extensive damage marine ecosystems. Effective methods for spillage recovery from offshore environments are still urgently in demand. A superhydrophobic sponge (MS@PVC@SiO2) was obtained via a facile two-step method rapid adsorption, piece of novel collection equipment loaded with MS@PVC@SiO2 develop...

The growths of oil and gas exploration and production activities have increased environmental problems, such as oil spillage and the resulting pollution. The study of the methods for cleaning up oil spills is a critical issue to protect the environment. Various techniques are available to contain oil spills, but they are typically time consuming, energy inefficient and create secondary pollutio...

various researches on laboratory and field scale illustrate that manipulating the ionic composition and the ion concentration of injected water can affect the efficiency of water flooding and the interaction of injected water with rock and other fluids present in porous media. the objectives of this paper are to investigate parameters that affect low salinity water flooding; mainly the effect o...

The objective of this study was to evaluate and obtain mathematical models, using the experimental design methodology, capable predicting contamination benzene, toluene, ethylbenzene xylenes (BTEX) in cases oil spillage at sea, acute toxicity soluble petroleum fraction (FSA). factorial planning developed describe concentration each compound according variables: °API, contact time oil/seawater a...

Uen-Chin Liang National Tsinghua University Department of Atomic Science Hsinchu 30043, Taiwan Abstract. Oil spillage in a body of water has been of great environmental concern. We present in this paper an automatic oil-spill detection system, which employs thin-film and wavefront-splitting interference techniques to determine the existence of surface oil or oil drops in water. Two independent ...

The hue and cry about the stark despoliation of the Niger Delta has been ongoing; and the issues at stake have centered mostly on the gross and glaring underdevelopment in the area despite the vast resources that have accrued to the Nigerian state from the region. Perhaps the most disturbing, is that oil exploration and exploitation in the Niger Delta is carried out without regard to internatio...

A short-term study was conducted after the oil spillage from the tanker Tasman Spirit to analyse seawater and sand samples taken from Karachi beach for hydrocarbon/organic contents. Blood samples were collected from people who were working or living in the vicinity of the beach. Lymphocyte and eosinophil levels were slightly increased. About 11 people had raised serum glutamic pyruvic transamin...

gas injection into heavy oil reservoirs could result in high ultimate recovery of oil. experimental studies showed that an application of a combined technology of gas assisted gravity drainage (gagd) and vapor extraction (vapex) could increase final oil recovery of a candidate viscous oil reservoir. in this paper the results of laboratory investigation are presented, including pressure-volume-t...

This contribution describes the procedure used during the Prestige oil-spillage event, by means of an Operational Oceanography System, and the behaviour of the present prediction tools (hydrodynamic and dispersion models) applied to it. The accuracy of these tools is estimated by a reanalysis of field data transmitted by a sea surface drifting buoy, released at the time of the oil spill. The nu...
