CO2 capture and utilization (CCU) is currently a global topical issue, and is viewed as one possible route to reduction of CO2 concentrations in the atmosphere. The core issues of development, economy and the environment which the world faces in current times are identified to be dependent on the provision ...
Abstract Oil spill dispersants (OSD) are known to be efficient tools needed to clean and disperse many oil spills. Dispersants are used to disperse oil and prevent them from reaching the shorelines. There are two major concerns in the use of dispersants on our environment. Their toxicity, because the ...
Abstract Surfactant Polymer (SP) flooding-a chemical EOR method, involves the injection of surfactants into the reservoir to reduce interfacial tension between oil and water and thus reduce capillary pressure for easy mobilization of oil. Polymers are also injected alongside to reduce mobility ratio ...
Abstract Over the past decade, system management approach has been evolving into a core business practice in government and industry. This approach is helping in the coordination of the efforts of people to accomplish goals and objectives using available resources efficiently and effectively, especially ...
Abstract This paper proposes solutions to safety issues by means of modifications to equipment engineering designs. Additionally, instilling a design-for-safety (DFS) philosophy helps further promote a safety culture. DFS is a key component of engineering. It is essential to anticipate and visualize ...
Abstract Supply chain in upstream oil & gas is complex and riddled with unique challenges. An E&P company transports a variety of materials ranging from an oil rig to a fastener. Large volume of import material is transported across international waters and then hauled to work sites deploying ...
Abstract Reservoir uncertainties, increasing water cut, vertical lift performance, well integrity issue along with decline in production are some of the typical challenges of a mature asset. These coupled with ageing facilities and lower production efficiencies are key issues that an operator faces ...
Abstract Adequate and efficient environmental monitoring is a key element of the environmental risk reduction process in the Oil & Gas industry, all the more where sensitive areas in harsh environmental conditions are at stake. This is the case in remote and extreme cold places such as the Arctic, ...
Abstract Current processes of globalization and integration of the companies into the world economy necessitated the unification of financial reporting to the third parties and external users, its transparency and uniformity of financial calculations and calculation procedures. International Financial ...
Abstract Extracted natural and associated petroleum gases contain water vapor, amount of which is determined by pressure, temperature, gas composition and salinity degree of formation water. The amount of water vapor in natural gas is regulated, because the moisture can condense in technological pipelines ...
Abstract The idea of using wellhead data for pressure transient analysis is very attractive, as if it is successful it spares us from the need to deploy any type of downhole tools, which are costly and wireline conveyed tools pose various mechanical risks including planting fish in the wellbore. The ...
Abstract Tahe Oilfield is an important oilfield of Sinopec in Northwest China. The reservoir temperature is up to 130°C, and the salinity is as high as 223,000 mg/L. Water production problem is getting worse along with the continuous water injection, but no gels can be successfully applied for water ...
Cement production is a major source of metals and metalloids in the environment, while exposures to metals and metalloids may impact human health in the surrounding communities. We recruited 185 participants living in the vicinity of a cement plant in the northeast U.S., and measured the levels of aluminum ...
While the commercialization of single-walled carbon nanotubes (SWCNTs) is rapidly expanding, the environmental impact of this nanomaterial is not well understood. Therefore, the present study evaluates the acute aquatic toxicity of SWCNTs towards two freshwater microalgae (Raphidocelis subcapitata and ...
The content of 12 elements in Cambodian dried striped snakehead fish was determined using inductively coupled plasma mass spectrometry. The present study compares the level of the trace toxic metals and nutritional trace elements in the fish processed using solar drying system (SDS) and open sun drying ...
Acute promyelocytic leukemia (APL) is classically characterized by chromosomal translocation (15;17), resulting in the PML-RARA fusion protein leading to disease. Here, we present a case of a 50-year-old man who presented with signs and symptoms of acute leukemia with concern for APL. Therapy was immediately ...
Objectives. To determine the dietary patterns of middle-aged Thais and their association with metabolic syndrome (MetS). Methods. The Thai National Health Examination Survey IV data of 5,872 participants aged ≥30–59 years were used. Dietary patterns were obtained by factor analysis and their associations ...
National Oceanic and Atmospheric Administration (NOAA) Method NMFS-NWFSC-59 2004 is currently used to quantitatively analyze seafood for polycyclic aromatic hydrocarbon (PAH) contamination, especially following events such as the Deepwater Horizon oil rig explosion that released millions of barrels ...
A gas chromatography equipped with mass spectrometer (GCMS) method was developed and validated for determination of 16 polycyclic aromatic hydrocarbons (PAHs) in fish using modified quick, easy, cheap, effective, rugged, and safe (QuEChERS) method for extraction and solid phase extraction for sample ...
Armor plate changes in sticklebacks are a classic example of repeated adaptive evolution. Previous studies identified ectodysplasin (EDA) gene as the major locus controlling recurrent plate loss in freshwater fish, though the causative DNA alterations were not known. Here we show that freshwater EDA ...
