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 ...
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 ...
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 ...
A comparative study of the lipid status (i.e., the total lipid and phospholipid concentrations and the percentage of fatty acids of the total lipids) of adult specimens of daubed shanny (Leptoclinus maculatus) from Svalbard waters (Isfjord) and slender eel blenny (Lumpenus fabricii) from the White Sea ...
Marine neurotoxins are natural products produced by phytoplankton and select species of invertebrates and fish. These compounds interact with voltage-gated sodium, potassium and calcium channels and modulate the flux of these ions into various cell types. This review provides a summary of marine neurotoxins, ...
Success of the shrimp aquaculture industry requires technological advances that increase production and environmental sustainability. Indoor, superintensive, aquaculture systems are being developed that permit year-round production of farmed shrimp at high densities. These systems are intended to overcome ...
Background Infectious Bovine Keratoconjunctivitis (IBK) in beef cattle, commonly known as pinkeye, is a bacterial disease caused by Moraxellabovis. IBK is characterized by excessive tearing and ulceration of the cornea. Perforation of the cornea may also occur in severe cases. IBK is considered 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 ...
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 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 ...
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 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 ...
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 ...
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 ...
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 ...
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 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 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 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 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 ...
