The possibility of producing stable oil-in-water (O/W) emulsions containing oil droplets surrounded by multiple layer interfacial membranes from food grade ingredients has been demonstrated. These emulsions were produced using a three stage process that relies on the adsorption of charged biopolymers to oppositely charged surfaces. Emulsions (0.5 wt % corn oil, 0.1 wt % lecithin, 0.0078 wt % ch...

Girth weld cracking is one of the main failure modes in oil and gas pipelines; girth weld cracking inspection has great economic and social significance for the intrinsic safety of pipelines. This paper introduces the typical girth weld defects of oil and gas pipelines and the common nondestructive testing methods, and systematically generalizes the progress in the studies on technical principl...

A collaboration between WPI and ENSIC was undertaken to investigate the properties of emulsions as a drug delivery system. The use of biocompatible amphiphilic polymers as emulsifiers for controlled drug delivery is a relatively new technology. The emulsifier acts as a barrier between phases in oil-in-water emulsions to increase stability. Oil soluble drug substances can then be encapsulated wi...

Synthetic Aperture Radar (SAR) technology has the ability to image surface oil seeps that originate by slow leakage from oiland gas-filled traps. Multi-temporal satellite data over such seeps delineate prospective areas and provide the locations for follow-up surface sampling from which key geochemical information of the reservoir oil can be obtained. Satellite radar can offer the oil industry ...

The high cost of commercial active carbon has motivated the study of new adsorbents materials with the aim to reduce costs of the residuary waters treatment by means of adsorption process. Among then, the pyrolyzed oil shale has demonstrated adsorbents characteristic and has been studied as adsorbent material for organic and inorganic pollutants. In oil refineries, before deciding for the impla...

Essential oils are used in a wide variety of consumer goods such as detergents, soaps, toilet products, cosmetics, pharmaceuticals, perfumes, confectionery food products, soft drinks, distilled alcoholic beverages (hard drinks) and insecticides. The world production and consumption of essential oils and perfumes are increasing very fast. Production technology is an essential element to improve ...

Color and size are two important attributes for quality evaluation of most food and bioproducts. Many of the quality factors affecting oil palm and white powder starch are determined primarily by visual inspection. Such inspections determined market price and to a certain extent consumers' preferences. However, the inspection of oil palm and white powder starch is a very repetitive and tedious ...

CO2 EOR and Storage in Oil Reservoirs — CO2 injection into tertiary oil reservoirs has been widely accepted as an effective technique for enhanced oil recovery (EOR), and has been used by the oil industry for over 40 years. Concerns over greenhouse gas emissions are leading to the investigation and realisation of its potential as a carbon storage method in recent years. With the right reservoir...

36 JPT • NOVEMBER 2014 To estimate reserves, optimize well recovery, and place future development wells more accurately, operators require increasingly detailed understanding of complex oil and gas reservoirs. Highresolution geological data from the borehole—core samples and wireline microresistivity images—are essential to fully characterize reservoir architecture, guide and constrain reservoi...

As the offshore market faces deepwater production challenges, the oil and gas industry is investing in new technologies to bring down the costs in the subsea fields exploitation. A breakthrough technology solution is the development of a subsea centrifugal compressor module installed on the seabed, transporting the wellstream to a central platform or directly to shore. The typical application o...
