Background Metabolic syndrome has become a major public health concern, but the role of diet in the etiology of this syndrome is not well understood. This study investigated the association between major dietary patterns and prevalence of metabolic syndrome in a Japanese working population. Methods This ...
Phishing email is one of the major problems of today's Internet, resulting in financial losses for organizations and annoying individual users. Numerous approaches have been developed to filter phishing emails, yet the problem still lacks a complete solution. In this paper, we present a survey of the ...
Understanding the effects of climatic variability on marine mammals is challenging due to the complexity of ecological interactions. We used general linear models to analyze a 15-year database documenting marine mammal strandings (1994–2008; n = 1,193) and nine environmental parameters known to affect ...
Among the class of pollutants considered as ‘emerging contaminants’, antibiotic compounds including drugs used in medical therapy, biocides and disinfectants merit special consideration because their bioactivity in the environment is the result of their functional design. Antibiotics can alter the structure ...
Shellfish waste components contain significant levels of high quality protein and are therefore a potential source for biofunctional high-value peptides. The feasibility of applying a pilot scale enzymatic hydrolysis process to whole Mytilus edulis and, by fractionation, recover hydrolysates presenting ...
Abstract When changing out completions in producing wells, inflatable tubing plugs are frequently used to control fluid loss and to protect equipment below the work area from the debris that results from pipe recovery and workover operations. To navigate the narrow inside diameter (ID) of production ...
Abstract Thru-Tubing Gravel Pack Techniques have been receiving an increasing attention in the recent years as a cost effective solution for sand producing wells with either failed gravel packs or zones that started sand production at a later stage during the life of the well especially in mature fields ...
Abstract Ichnofossils and paleosols are powerful tools for reconstructing paleoenvironments and depositional histories of sediments in the coastal transition zone, where physicochemical factors of the continental and marine realms meet. Distinguishing alluvial, coastal-plain, deltaic, and estuarine ...
Abstract Legal license to design, construct, and operate a major project in any country is granted by the government and regulatory bodies of the respective country. Such is the case with the PNG LNG Project currently being built by ExxonMobil and its co-venturers in Papua New Guinea (PNG). ...
Abstract Inhibitor squeeze treatments have been regularly carried out to prevent both sulphate and carbonate scale depositions from reservoir to topside facilities in North Sea field since 1990s. Some of the wells, especially for the short perforation, high water production wells and relatively clean ...
Abstract Peciko is one of the giant gas fields located in the Mahakam area, Indonesia, operated by Total E&P Indonesie. Since start up in December 1999, until May 2012, the average wellhead pressure and temperature of its wells have decreased from 150 barg to 20 barg and from 95 °C to 60 °C, respectively, ...
Abstract In the past, containment of hydraulic fracture height growth has been evaluated based on an assumption of rock formation layers with contrasting conditions of minimum horizontal stress, and to a lesser extent, Young's modulus, leak off rates, and fracture toughness between adjacent rock layers. ...
Abstract A deepwater batch drilling project in north Borneo was planned to produce oil at full potential through water and gas injection wells. The field is located 75 miles offshore in water depths in excess of 3,300 ft. Failure of formation isolation valves (FIV) to open hydraulically in the two ...
Earth is a finite system with a limited supply of resources. As the human population grows, so does the appropriation of Earth’s natural capital, thereby exacerbating environmental concerns such as biodiversity loss, increased pollution, deforestation and global warming. Such concerns will negatively ...
Introduction: The subject well, located onshore in the Kingdom of Saudi Arabia, had approximately 9,000 ft of 2.00-in coiled tubing lost in the wellbore, and was requiring thru-tubing intervention to recover the parted string and subsequently abandon the well. The string was lost following a failed ...
Abstract Separated layer water injection is the important technology to realize the oilfield long-term high and stable yield. Through continuous researches and technological innovations, series separated layer water injection technologies have been developed to meet the technology needs of the different ...
Environmental DNA (eDNA) is being rapidly adopted as a tool to detect rare animals. Quantitative PCR (qPCR) using probe-based chemistries may represent a particularly powerful tool because of the method’s sensitivity, specificity, and potential to quantify target DNA. However, there has been little ...
Abstract This paper shares and discusses the challenges faced and activities that led to a significant discovery in a deep carbonate reservoir. It covers the successful well-testing design as well as the methods and procedures adopted to complete short term test of this well safely. A new structure ...
Abstract In 2012, in its first field trial, an electric-line-conveyed mechanical cutting tool was used to cut completion tubing in a well off the east coast of Russia. This e-line cutting tool required no explosives, no chemicals, and no subsequent run to dress the top of the cut, as is typically the ...
Abstract An operator had live perforating guns stuck in the casing at 14,100 ft. The wireline had been pulled out of the rope socket, leaving 67 ft of wireline tools, perforating guns, and plug assembly stuck in the wellbore with 8,300-psi surface pressure. To remediate this issue, a 144-ft tall snubbing ...
