Injection of optimized chemistry water in enhanced oil recovery (EOR) has gained much interest in the past few years. Crude oil-water interfaces can have a viscoelastic character affected by the adsorption of amphiphilic molecules. The brine concentration as well as surfactants may strongly affect the fluid-fluid interfacial viscoelasticity. In this work we investigate interfacial viscoelastici...

The recent development of tight oil reservoirs has led to an increase in oil production in the past several years due to the progress in horizontal drilling and hydraulic fracturing. However, the expected oil recovery factor from these reservoirs is still very low. CO2-based enhanced oil recovery is a suitable solution to improve the recovery. One challenge of the estimation of the recovery is ...

A significant quantum of crude oil is trapped in reservoirs and often unrecoverable by conventional oil recovery methods. Further downstream, the petroleum industry is facing challenges to remove sulfur, metal, nitrogen as well as undesirable organic compounds from the crude. Conventional secondary recovery methods such as water and gas injections helped to increase the productivity of the well...

Gallbladder perforation with subsequent gallstone spillage can occur with higher frequency in laparoscopic cholecystectomy than in traditional open approach. Gallstone abscess formation from stone spillage post-cholecystectomy is extremely rare. We present a case of para-spinal abscess formation 5 years after spilled gallstones following laparoscopic cholecystectomy.

This study is aimed at verifying the relevance of Ucides cordatus as a bioindicator of oil contamination and PAH bioavailability in mangrove sediments. For this, crabs and sediment cores were sampled from five mangroves, including an area suspected of contamination derived from an MF380 oil spillage, and analyzed for the 16 PAH in the USEPA priority list as well as for the five series of alkyla...

Crude oil is the major source of energy worldwide being exploited as a source of economy, including Oman. As the price of crude oil increases and crude oil reserves collapse, exploitation of oil resources in mature reservoirs is essential for meeting future energy demands. As conventional recovery methods currently used have become less efficient for the needs, there is a continuous demand of d...

Gas Chromatography /Mass Spectrometry method of analysis was used to determine the presence and quantitative values selected Oxygenates Organic micropollutants in underground water oil spillage prone areas Lagos State Nigeria. The involved six samples with three collected from each sampled sites. were analyzed using GC/MS concentrations various oxygenates such as MTBE, Benzene, Methanol, Ethano...
