One of the possible fluid-fluid interactions during water-flooding in oil reservoirs, that is still debated, effect injected brine salinity on asphaltene destabilization. If precipitation induced by changes reservoirs and surface facilities, this could have a massive impact economy low project. Therefore, study aims to investigate amount governing destabilization mechanisms. Direct measurements...

Exposure to water containing petroleum waste products can generate both overt and subtle toxicological responses in wildlife, including birds. Such exposure can occur in the tailings ponds of the mineable oil sands, which are located in Alberta, Canada, under a major continental flyway for waterfowl. Over the 40 year history of the industry, a few thousand bird deaths have been reported followi...

Oil sands process-affected water (OSPW), produced by surface-mining of oil sands in Canada, is alkaline and contains high concentrations of salts, metals, naphthenic acids, and polycyclic aromatic compounds (PAHs). Residual hydrocarbon biodegradation occurs naturally, but little is known about the hydrocarbon-degrading microbial communities present in OSPW. In this study, aerobic oxidation of b...

The alkaline lake source rocks of the Fengcheng Formation are developed in Mahu Sag Junggar Basin. Different from traditional continental fresh water and saltwater rocks, lack targeted evaluation criteria, it is unknown whether their hydrocarbon generation models consistent with models. Therefore, present study, standards discussed based on geological organic geochemical data a systematic summa...

Naphthenic acids (NAs) have been implicated as some of the most toxic substances in oil sands leachates and identified as priority substances impacting on aquatic environments. As a group of compounds, NAs are not well characterized and comprise a large group of saturated aliphatic and alicyclic carboxylic acids found in hydrocarbon deposits (petroleum, oil sands bitumen, and crude oils). Descr...

در طبیعت میکروارگانیسم ها به طور عمده به صورت جمعیت های استقرار یافته بر روی سطوح هستند که بوسیله ماتریکس خارج سلولی احاطه شده اند و بیوفیلم نامیده می شوند. میکروارگانیسم ها در داخل بیوفیلم ها از تحمل بسیار بالایی به ترکیبات ضد میکروبی برخوردار هستند که این ویژگی ریشه کنی آنها را بسیار دشوار می سازد. هدف از این مطالعه بررسی آخرین و مبهم ترین مرحله توسعه بیوفیلم که شامل پراکندگی هماهنگ سلول های ...
