The Cambrian Longwangmiao gas reservoirs in the Moxi area of Sichuan Basin have a complex associated accumulation history. Based on core and thin section examination, fluid inclusion analyses 1-D burial-thermal modelling, diagenetic evolution hydrocarbon processes Formation been reconstructed. Various events were identified, making up complete pore fill sequence as follows: solid bitumen/dolomi...

Sediments and rocks recovered in CRP-2/2A coring operations contain relatively little organic matter (average TOC=0.28%) and very small amounts of solvent-soluble organic matter. Because Early Oligocene sediment included significant amounts of coal detritus, TOC values are higher in Early Oligocene rocks than in younger rocks. TOC values are highest in the fine-grained rocks deposited as part o...

Bitumens fumes contain polycyclic aromatic compounds (PAC). There is a possibility of long-term health effects following chronic exposure by inhalation or skin contamination in asphalt road pavers and highway maintenance workers. Epidemiological and experimental studies on this topic are reviewed and the possible causes of cancer discussed with a primary focus on heterocyclic polyaromatic compo...

Moist exposed burn ointment (MEBO) is a fairly recent addition to the English burn literature for the local treatment of the burn wound. MEBO espouses the concept of wound healing in a moist environment by avoiding desiccation of the fragile burned areas. Though MEBO is as effective as conventional management, it is not the panacea for all burn wounds [1]. While using MEBO in the treatment of p...

The ageing of asphalt mixes, together with their exposure to low temperatures, causes a progressive increase of cracking. In this paper, the effect of ageing and temperature on the fatigue of asphalt concretes made with two types of binders, conventional (50/70) and polymer modified bitumen (PMB), is studied. For this purpose, specimens previously subjected to an accelerated laboratory ageing p...

The influence of natural rubber along-side with chlorine gas on the bitumen blends characteristics have inspected. modification performed through passing molten mix prepared using and latex variety percentages. Penetration, penetration index, ductility softening point tested. In addition, viscoelasticity, rutting resistance thermal stability measured dynamic shear rheometric analysis differenti...

Plastic (Polyethylene Terephthalate, PET) is now used as packaging material for a whole range of consumer products in addition to carbonated beverages. Although plastics are very useful product, but the disposal of these wastes has become a problem and is of great concern, particularly in our country. One of the solutions to the disposal of plastic wastes is recycling it...

This paper advances ideas and presents experiments on the flow characteristics of concentrated emulsions of Venezuelan bitumen in water plus surfactant. These emulsions are studied under a variety of flow conditions, namely between rotating cylinders, in a colloid mill and in pipes. The ideas advanced here concern the modeling of the highly viscous bitumen drops as solid spheres and their fract...

Manifestation of rheological properties of bituminous binders over a wide a range of temperature in real life pavements can be attributed to various factors viz. crude source, processing methods, oxidative aging and chemical composition. A clear understanding of the fundamental chemical and rheological properties of bitumen and their interrelationship is important to address issues related to b...
