Abstract:Maintaining the viscosity and fluid loss ability during drilling operation is core for a drilling fluid to perform its functions effectively. The unfriendly conditions such as high temperature and pressures encountered as drilling operations cut deeper into formations require robust drilling mud formulae that would provide thermal stabilization of the drilling fluids while maintaining their rheological integrity. This research work investigates the stability of the oxides of Iron nanoparticles on the rheological properties of water based bentonite mud. The work focused on the effect of the nanoparticles on the rheology of the bentonite drilling fluid, as well as, their degree of thermal stabilization on the working fluid. The interactive effects of the iron oxide nanoparticles, temperature and shear rate on the shear stress of the drilling were also analyzed. We also showed quantitative relationship of the nanoparticle, temperature and shear rate at the optimization points of the shear rate.

“…Нефть, дизельное топливо и минеральное масло -это самые распространен-ные дисперсионные среды буровых растворов на углеводородной основе (Khodja et al, 2010), они характеризуются высокой токсичностью по отношению к живым организмам (Cunningham, Philp, 2000). В этой связи была изучена деструктивная активность выделенных микроорганизмов по отношению к данным дисперсион-ным средам (нефтепродуктам) РУО, которые вносили в минеральную среду М9 в качестве единственного источника углерода и энергии в концентрации 0.4% (по весу).…”

“…Известно, что в дизельном топ- ливе преобладают простые неразветвленные н-алканы (Heath et al, 1997). И хотя метаболизм н-алканов (С 6 -С 12 ) возможен, многие из них действуют как раствори-тели, разрушая клетки посредством частичной солюбилизации мембранных фос-фолипидов, оказывая, таким образом, токсическое действие на многие микроорга-низмы (Khodja et al, 2010). Возможно, исследованные нами бактерии также оказа-лись подвержены токсическому действию низкомолекулярных алканов дизельного топлива.…”

Поступила в редакцию 04.09.16 г.Особенности деградации углеводородов бактериями, выделенными из буровых шламов. -Плешакова Е. В., Беляков А. Ю., Деев Д. В. -Показано, что выделенные из буровых шламов микроорганизмы -Bacillus circulans НШ, B. firmus ОБР 1.1, B. firmus ОБР 3.1, Solibacillus silvestris ОБР 3.2, B. circulans ОБР 3.3, Halomonas sp. ОБР 1 и Erwinia rhapontici ОБР 4.1 -способны к деструкции нефти, минерального масла и дизельного топ-лива. Установлено, что бактерии B. circulans НШ и B. firmus ОБР 1.1 деградируют нефть в щелочной среде (рН 9) на 62 и 36% за 14 сут., в минерализованной среде (10% NaCl) на 42 и 22%. Продемонстрировано, что бактерии B. circulans НШ и S. silvestris ОБР 3.2 эффективно деградируют нефтяные углеводороды в условиях повышенной солености и щелочности среды не только самостоятельно, но и в комбинации с нефтеокисляющим микроорганизмом Dietzia maris АМ3. Эффективность деструкции нефти ассоциацией B. circulans НШ + D. maris АМ3 выше, чем монокультурой.Ключевые слова: буровые шламы, нефтяные углеводороды, микробные штаммы, деградация.Percularities of hydrocarbon degradation by bacteria isolated from drill sludge. -Pleshakova Ye. V., Belyakov A. Yu., and Deev D. V. -Some microorganisms isolated from drill sludge (Bacillus circulans NSh, B. firmus OBR 1.1, B. firmus OBR 3.1, Solibacillus silvestris OBR 3.2, B. circulans OBR 3.3, Halomonas sp. OBR 1, and Erwinia rhapontici OBR 4.1) have been shown to be capable of degrading crude oil, mineral oil, and diesel fuel. It has been established that the B. circulans NSh and B. firmus OBR 1.1 bacteria degrade 62 and 32% of crude oil, respectively, in an alkaline medium (pH 9) for 14 days and degrade 42 and 22%, respectively, in a saline medium (10% NaCl). It was demonstrated that under high salinity and alkalinity conditions the B. circulans NSh and S. silvestris OBR 3.2 bacteria effectively degraded petroleum hydrocarbons not only solely but also in combination with the crude-oil-oxidizing Dietzia maris AM3 microorganism. The efficiency of crude oil degradation by the B. circulans NSh + D. maris AM3 association was higher than that by each monoculture.

WELLS. The growing global concern about the environment associated with academic and government efforts are enabling a number of alternatives for sustainable development. Within this perspective one can include the search for value-added products using waste from renewable energy sources, such as those from the production of biodiesel. The rapid development of biodiesel production in Brazil directly affected the supply of glycerin and therefore the sector is seeking a market that can absorb this waste. Thus, with the increasing search for environmentally friendly products, formulation of a drilling fluid using a co-product of biodiesel production to replace the n-paraffin is of great importance to the oil industry for meeting the requirement of environmental regulation and, in addition, considerably reducing the cost of raw materials. In this context, the aim of this study was to characterize different glycerins to evaluate their potential as basis for drilling fluids for oil wells and gas. The glycerins were stable under the conditions evaluated without phase separation and precipitation of solids, exhibited good rheological profile and low value of interface tension. The results indicate a strong possibility of use of these glycerins as basis for drilling fluids and applicability by the oil industry.Keywords: glycerin; drilling fluids; petroleum industry. INTRODUÇÃOFluidos de perfuração para poços de petróleo e gás são dispersões complexas de sólidos, líquidos e/ou gases, usualmente constituídas de uma fase dispersante ou base (aquosa ou orgânica) e outra dispersa, cuja complexidade depende da natureza dos produtos dispersos, dos requisitos e das funções necessárias para operação de perfuração, tais como manutenção da integridade da parede do poço, remoção dos cascalhos gerados durante o processo de perfuração, resfriamento e lubrificação da coluna de perfuração e da broca. 1 Dependendo da composição de sua fase dispersante, os fluidos de perfuração podem ser à base de água (Water-Based Drilling Fluids -WBDF), à base de gás (Gas-Based Drilling Fluids -GBDF) e à base de óleo (Oil-Based Drilling Fluids -OBDF), que inclui fluidos de base oleosa sintética (Synthetic-Oil-Based Drilling Fluids -SOBDF).Desde o início da utilização de fluidos de perfuração, quando se utilizava a água para auxiliar as ferramentas na construção dos poços de água subterrânea, seu desenvolvimento permanece até hoje como um grande desafio para a indústria do petróleo, na busca por um fluido que seja de baixo custo, de fácil manipulação, com propriedades técnicas adequadas e ambientalmente correto. 2 A indústria do petróleo investe permanentemente em pesquisa e desenvolvimento de novas tecnologias, tanto em produtos (aditivos) quanto em novas bases para sistemas de fluidos de perfuração, especialmente no Brasil, à medida que os poços de petróleo e gás se tornam mais profundos e novos cenários mais complexos vão surgindo, tais como os poços de petróleo perfurados no cenário do pré-sal e poços com geometria complexa envolvendo trechos de alta...
