Marine bivalves, which include many species worldwide, from intertidal zones to hydrothermal vents and cold seeps, are important components of the ecosystem and biodiversity. In their living habitats, marine bivalves need to cope with a series of harsh environmental stressors, including biotic threats ...
The polyether toxin, okadaic acid, causes diarrhetic shellfish poisoning in humans. Despite extensive research into its cellular targets using rodent models, we know little about its putative effect(s) on innate immunity. We inoculated larvae of the greater wax moth, Galleria mellonella, with physiologically ...
Abstract ADNOC Offshore operates more than 1300+ numbers of oil, gas and water offshore wells of age 59 years on wards, at 300+ well head platforms located in shallow to intermediate water depth of 7m-34m for various fields. Well conductors being outer pipes of the well construction, its functionality ...
Abstract An offshore gas field located in a cold area; with an average temperature of 13 Celsius degree and −1.2 Celsius degree under sea level. The reservoir is located 200 meters under the sea floor, where the sea floor is 850-1100 meter depth and 120 Km away from shore. The objective is to develop ...
Abstract In congested districts of offshore Oil & Gas Industry, merchant ship traffic, offshore operations or fishing activity may interfere with pipelines in service, which rest exposed on the seabed. Despite the shortcomings of existing technology and knowledge, operators' concerns still emerge after ...
Abstract Plasma-based technology for various upstream applications has been under development for a couple of years. The first commercial application is for wellbore tubular removal or "milling" for Well Plug and Abandonment the main focus being the North Sea and Gulf of Mexico. In parallel to this ...
Abstract Wireline cable sticking is most frequently experienced during formation fluid sampling. In this situation, if the cable cannot be freed, strip-over fishing is the only remedy; this is a cost and risk-intensive activity which may extend the logging job by several days and result in further ...
Abstract The scope of this paper is to describe the advantages of utilizing Elastomeric Wraps for repairing and protecting offshore boat landing piles located in the splash-zone, which is a challenge worldwide, and to make comparison between this new protective Wraps and our existing repair practice. ...
Abstract More than two decades that the Gulf of Thailand (GOT) has been installed with petroleum hydrocarbon production platforms, currently over 400 platforms were installed and operated. Since mercury is a common contaminant in petroleum hydrocarbon production in Southeast Asia, minimal risk and ...
Abstract The nuclear envelope serves as important messenger RNA (mRNA) surveillance system. In yeast and human, several control systems act in parallel to prevent nuclear export of unprocessed mRNAs. Trypanosomes lack homologues to most of the involved proteins and their nuclear mRNA metabolism is ...
The prevalence of diabetes is steadily rising, and once it occurs, it can cause multiple complications with a negative impact on the whole organism. Complications of diabetes may be macrovascular: such as stroke and ischemic heart disease as well as peripheral vascular and microvascular diseases—retinopathy, ...
Background Nucleoplasmin 2 (npm2) is an essential maternal-effect gene that mediates early embryonic events through its function as a histone chaperone that remodels chromatin. Recently, two npm2 (npm2a and npm2b) genes have been annotated in zebrafish. Thus, we examined the evolution of npm2a and ...
Many pharmaceuticals have negative effects on biota when released into the environment. For example, recent work has shown that the commonly prescribed antidiabetic drug, metformin (N,N-dimethylbiguanide), has endocrine disrupting effects on fish. However, effects of metformin on aquatic primary producers ...
Abstract The daily drilling report (DDR) contains the daily activities and parameters during drilling and completion (D&C) operations that can be used to identify the bottlenecks and improve efficiency. However, the datasets are large, unstructured, text heavy, not correlated to other datasets, ...
Abstract In a global first, Mubadala Petroleum in Thailand has successfully completed a three-month trial of a new technology designed to improve the operational performance of the regular program of well maintenance workovers required for its Gulf of Thailand fields. The trial tested the use of an ...
Abstract Conventional Coiled tubing well intervention has been carried out in oil and gas wells for more than 30 years with not real-time data acquisition. With the advent of Coiled Tubing Telemetry (CTT) e-line/fiber optics/mono conductors in coiled tubing industry, a wide variety of opportunities ...
An injector well drilled from an artificial island in UAE left a non-magnetic fish during well control operations across lower Cretaceous reservoirs below the 9-5/8-in. casing shoe, exposing all upper Jurassic reservoirs flow units. The situation was a serious concern to field developing and reservoir ...
Abstract Sidetracking a preexisting drilled and cased wellbore poses numerous challenges. When sidetracking in an openhole environment, additional verifications of hole conditions are needed, which contribute additional unique challenges. In this type of wellbore, the operators must plan by selecting ...
Abstract Since 2014, ADNOC Onshore has utilized the potential of hoists and commissioned its operational significance, which allowed saving in rig time (4 – 6 rig years per year over 5 years business plan period) and generating a cost saving opportunity. During this period we have faced many challenges ...
