There are techniques for the treatment of the same, but there isn t consensus on what are the best in terms of economic and environmental. One alternative for disposal of this waste and objective of this paper is the incorporation and immobilization of gravel clay matrix to assess their technological properties. The Raw Materials used were characterized by the following techniques: Chemical Analysis by X-ray fluorescence (XRF), mineralogical analysis by X-ray Diffraction (XRD), Grain Size Analysis (FA) and Thermal Analysis by Thermogravimetry (TG) and thermodiferential (DTA). After characterizing, samples were formulated in the following percentages: 0, 5, 10, 15, 25, 50, 75, 100% (weight) of gravel drilling, then the pieces were pressed, dried (110 ? C) and sintered at temperatures of 850, 950 and 1050 ? C. After sintering, samples were tested for water absorption, linear shrinkage, flexural strength, porosity, density, XRD and test color. The results concluded that the incorporation of gravel drilling is a viable possibility for solid masonry bricks and ceramic blocks manufacture at concentrations and firing temperature described here. Residue incorporation reduces an environmental problem, the cost of raw materials for manufacture of ceramic products / Um dos res?duos produzidos em grande escala durante a perfura??o de po?os de petr?leo ? o cascalho de perfura??o.

O cascalho de perfura??o ? um res?duo gerado em grande quantidade no processo de perfura??o de po?os e que pode provocar impactos ambientais, tais como a contamina??o do solo e consequentemente a contamina??o de len??is fre?ticos, caso descartados sem tratamento pr?vio. Surge ? necessidade de se desenvolver atividades cient?ficas e de pesquisar maneiras de adequar esses res?duos as normas ambientais vigentes. No caso dos res?duos s?lidos, a norma NBR 10004:2004 da Associa??o Brasileira de Normas T?cnicas (ABNT) classifica-os em res?duos classe I (perigoso) e classe II (n?o perigoso), onde estabelece quais os res?duos que podem ou n?o ser descartados no meio ambiente sem provocar impacto ambiental. Este trabalho apresenta uma inovadora alternativa para tratar o cascalho de perfura??o, que ? classificado como res?duo classe I (Abreu & Souza, 2005), removendo principalmente a n-parafina presente no mesmo, uma vez que este ? originado quando se usa fluidos de perfura??o base ?leo. Utilizando sistemas microemulsionados promove-se a remo??o deste contaminante de amostras de cascalho de perfura??o provenientes de po?os localizados em Alto do Rodrigues ? RN. Inicialmente, determinou-se a concentra??o de parafina utilizando o m?todo de infravermelho, em amostras previamente extra?das com ultrassom, obteve-se uma concentra??o de parafina na faixa de 36,59 a 43,52 g de parafina por quilograma de cascalho. Utilizou-se dois sistemas microemulsionados contendo dois tensoativos n?o i?nicos de diferentes classes, um ? um ?lcool etoxilado (UNTL-90) e o outro um nonifenol etoxilado (RNX 110). Os resultados indicaram que o sistema com tensoativo UNTL-90 possui melhor efici?ncia que o sistema com RNX 110. O estudo da influ?ncia do tempo de contato na extra??o mostrou que para tempos maiores que 25 minutos tem-se uma tend?ncia ao aumento do percentual de extra??o com o aumento do tempo de contato. Observou-se tamb?m que a extra??o ? r?pida, pois em 1 minutos de contato tem-se 22,7 % de extra??o. A reutiliza??o do sistema microemulsionado, sem a remo??o da parafina extra?da em etapas anteriores, mostrou redu??o de 29,32 no percentual de extra??o comparando a primeira e a terceira extra??o, mas comparando a primeira e segunda extra??es a redu??o ? de 8,5 no percentual de extra??o, logo a otimiza??o da reutiliza??o dos sistemas pode ser uma op??o para viabilizar economicamente a remo??o de parafina de cascalho. A extra??o com agita??o se mostrou mais eficaz no tratamento do cascalho, atingindo o percentual de extra??o de 87,04 %, ou seja, se obt?m um cascalho de perfura??o com 0,551 % de parafina. Utilizando o percentual de parafina empregado nos fluidos de perfura??o n?o aquosos e o limite m?ximo de fluido no cascalho para descarte estabelecido pela Ag?ncia de Prote??o Ambiental dos Estados Unidos (US Environmental Protection Agency - US EPA), chega-se ? conclus?o que o teor de parafina no cascalho n?o pode ser superior a 3,93 %. Conclui-se que a quantidade de parafina no cascalho tratado com o sistema microemulsionado e com agita??o est? bem abaixo do estabelecido pelo ?rg?o americano (US EPA), mostrando que o sistema microemulsionado utilizado foi eficiente na remo??o da parafina do cascalho de perfura??o. / The oil industry is one of the activities that generates more waste to the environment. The drill cuttings is a waste generated in large quantities in the drilling process and that may cause environmental damage such as soil contamination and consequently the contamination of groundwater if disposed of without prior treatment. Arises the need to develop scientific activities and research ways to adapt these wastes the current environmental standards. In the case of solid wastes, the NBR 10004: 2004 of the Brazilian Association of Technical Standards (ABNT) classifies them into class I waste (hazardous) and class II (not dangerous), which determines which wastes may or may not be discarded in the environment without causing environmental impact. This study presents a novel alternative for treating drill cuttings, where this waste was classified as class I (Abreu & Souza, 2005), mainly by removing the n-paraffin present in it, since this arises when using drilling fluids base oil. Using microemulsion systems promotes the removal of this contaminant drill cuttings samples from wells located in Alto do Rodrigues - RN. Initially, we determined the concentration of paraffin using infrared method in samples were extracted with ultrasound, we obtained a paraffin concentration in the range from 36.59 to 43.52 g of paraffin per kilogram of cuttings. Used two microemulsion systems containing two nonionic surfactants from different classes, one is an alcohol ethoxylated (UNTL-90) and the other an nonylphenol ethoxylated (RNX 110). The results indicated that the system UNTL-90 surfactant has better efficiency than the system with RNX 110. The study of the influence of contact time at the extraction showed that for times greater than 25 minutes has a tendency to increase the percentage extraction with increasing contact time. It was also observed that the extraction is fast because at 1 minute contact has 22.7% extraction. The reuse of the microemulsion system without removing the paraffin extracted in previous steps, showed reduction of 29.32 in percentage of extraction by comparing the first and third extraction, but by comparing the first and second extractions reduction is 8.5 in percentage extraction, so the systems reuse optimization can be an option for economically viable removing paraffin from cuttings. The extraction with shaking is more effective in the treatment of cuttings, reaching the extraction percentage of 87.04%, that is, obtaining a drill cuttings with 0.551% paraffin. Using the percentage of paraffin employed in non-aqueous drilling fluids and fluid maximum limit on cuttings for disposal established by the Environmental Protection Agency of the United States (US EPA), one arrives at the conclusion that the level of paraffin on gravel cannot exceed 3.93%. Conclude that the amount of paraffin in the treated cuttings with the microemulsion system with shaking is below the established by US EPA, showing that the system used was efficient in removing the paraffin from the drill cuttings.

Control of environmental impacts caused by this waste represents a major challenge. Such impacts can be minimized when it is given an appropriate management by being properly treated and properly disposed or recycled. The properties of these materials can be greatly influenced when a waste is added to its composition. This work aims to study the incorporation of gravel waste oil-well drilling in the standard body for production of red ceramic from a ceramic industry in S?o Gon?alo do Amarante / RN. The success of the incorporation can minimize costs in the production of ceramic pieces and reduce the environmental impacts caused by waste. The raw materials used were collected, characterized, and formulated with the percentages of 0%, 20% and 40% by weight of substitution of residue were synthesized at temperatures of 900, 1.010 and 1.120 ?C using 30 minute firing intervals, 1 hour and 30min and 2 hours and 30 minutes, based on a factorial design 2?. Samples were then subjected to the tests of Water Absorption, Linear Retraction Firing, Flexural Rupture Strength, Apparent Porosity and Apparent Specific mass and Scanning Electron Microscopy (SEM) of break section. The results showed that the use of the residue for the manufacture of the ceramic products is possible (tiles, bricks and massive hollow bricks) replacing the clay to 40%, meeting the requirements of the standard and the literature for the technological properties of the final product.

Their mineralogical characteristics depend on the geological formation present along the perforation. Upon reaching the surface, it is impregnated with drilling fluid used during the process. The use of this waste in soils has been discussed as it has limitations per se (e.g. high content of Fe, Mn, Zn, Cu) as a consequence of the drilling process (e.g. Ba, Na and hydrocarbons - HTP). The purpose of this study was to investigate the decrease of salinity after the application of gravel with castor cake to the substrate and using the castor bean BRS- 149 cv. Nordestina, as plant indicator, to infer about limitations on the combined use of these wastes. Pots were used (8 dm3) with proportional doses of gravel (control, 5, 15, 30, 45 and 60 Mg ha-1) associated with castor cake (control, 2, 4, 8, 16 and 32 Mg ha-1) in a factorial design with three replications for 97 days after planting (DAP). Improvements were observed in the morphological development of castor bean plants, with the application of 60 Mg ha-1 gravel associated with 16 Mg ha-1 of castor cake. However, the dose of 60 mg ha-1 of gravel caused stress due to accumulation of Na in leaves, the same for the 45 mg h-1 dose. The best ratio of gravel and pie in this respect was of 15 and 32 mg h-1, respectively. After the initial cultivation of castor bean plants, it was found that the application of 30 Mg ha-1 of gravel was sufficiently capable to neutralizing the toxic Al3+; raising the pH to values around 6.5 and thus making the nutrients more avalilable to the crop. Also, there was a marked HTP decomposition (above 92%) from the substrate metabolical microbiological increase, with the pie addition. It was therefore concluded that the use of gravel must follow specific guidelines especially due to salinity, to avoid possible impacts caused to the environmental and the crop (castor bean). / O cascalho de perfura??o ? um res?duo da ind?stria do petr?leo produzido durante a perfura??o de po?os terrestres e mar?timas, cujas caracter?sticas mineral?gicas dependem da forma??o geol?gica presente ao longo da perfura??o.

Foram utilizados vasos com capacidade de 8 dm3, utilizando doses proporcionais de cascalho (controle, 5, 15, 30, 45 e 60 Mg ha-1) associado a doses de torta de mamona (controle, 2, 4, 8, 16 e 32 Mg ha-1) em fatorial com tr?s repeti??es durante 97 dias ap?s plantio (DAP). Foram observadas melhorias no desenvolvimento morfol?gico da mamoneira, com a aplica??o de 60 Mg ha-1 de cascalho associado ? 16 Mg ha-1 de torta de mamona. Contudo, a dose de 60 Mg ha-1 de cascalho causou estresse por apresentar ac?mulo de Na nas folhas, o mesmo com a dose de 45 Mg ha-1, onde a melhor rela??o, de cascalho e torta, neste contexto, foi de 15 e 32 Mg ha-1, respectivamente. No que tange a melhoria do solo ap?s o cultivo inicial de mamona, foi constatado que a aplica??o de 30 Mg ha-1 de cascalho foi suficientemente capaz de neutralizar o Al3+ t?xico, na eleva??o do pH em torno de 6,5, e assim disponibilizando nutrientes para a cultura. Tamb?m verificou-se decomposi??o acentuada de HTP (acima de 92%) proveniente do metabolismo microbiol?gico no substrato, auxiliada pela adi??o de torta. Concluiu-se ent?o que o emprego do cascalho em solo deve seguir orienta??es espec?ficas e ponderadas, no que tange principalmente ? salinidade, para que n?o haja preju?zo ambiental e ? cultura da mamona.

The soil-cement bricks are one of the alternatives to masonry construction. These elements, after a short curing period, provide compressive strength similar to that of solid bricks and ceramic blocks, and the higher the resistance the higher the amount of cement used. We used the soil from the city of S?o Jos? do Mipibu / RN, the banks of the River Baldun, cement CPIIZ-32 and residue of drill cuttings from oil wells drilling onshore wells in the town of Mossley, RN, provided Petrobras. To determine the optimum mix, we studied the inclusion of different residues (100%, 80%, 70%, 60% and 50%) where 15 bodies were made of the test piece. The assessment was made of bricks made from simple compression tests, mass loss by immersion and water absorption. The experimental results proved the efficiency and high utilization of the waste from the drilling of oil wells, making the brick-cement-soil residue with a higher strength and lower water absorption. The best result in terms of mechanical strength and water absorption for the ternary mixture was 10% soil, 14% cement and 80% residue. In terms of binary mixtures, we obtained the best result for the mix-cement residue, which was 14% cement incorporated in the residue / O presente trabalho consiste no estudo das caracter?sticas e propriedades tecnol?gicas de tijolos solo-cimento formulados a partir de misturas bin?rias e tern?rias de cimento Portland, areia, ?gua, com e sem adi??o de cascalho proveniente da perfura??o de po?os de petr?leo, que poder?o ser utilizados pela ind?stria, com o objetivo de melhorar seu desempenho e diminuir seu custo utilizando o res?duo e, conseq?entemente, aumentando sua vida ?til. Os tijolos de solo-cimento constituem uma das alternativas para a constru??o em alvenaria. Esses elementos, ap?s pequeno per?odo de cura, garantem resist?ncia ? compress?o simples similar ? dos tijolos maci?os e blocos cer?micos, sendo a resist?ncia tanto mais elevada quanto maior for ? quantidade de cimento empregada. Foi utilizado o solo proveniente do Munic?pio de S?o Jos? do Mipib?/RN, as margens do Rio Baldun, cimento CPIIZ-32 e res?duo de cascalho de perfura??o de po?os de petr?leo proveniente da perfura??o de po?os Onshore, no munic?pio de Mossor?/RN, fornecido pela Petrobras. Para a determina??o da mistura ?tima, estudou-se a inclus?o de teores de res?duos diferenciados (100%; 80%; 70%; 60% e 50%) onde foram confeccionados 15 corpos-de-prova. A avalia??o dos tijolos confeccionados foi feita a partir de ensaios de compress?o simples, perda de massa por imers?o e absor??o de ?gua. Os resultados experimentais comprovaram a efici?ncia e o elevado potencial de utiliza??o do res?duo proveniente da perfura??o de po?os de petr?leo, tornando o tijolo de solo-cimento-res?duo com uma maior resist?ncia mec?nica e menor absor??o de ?gua. O melhor resultado, em termos de resist?ncia mec?nica e absor??o d ?gua, para a mistura tern?ria, foi de 10% de solo, 14% de cimento e 80% de res?duo. Em termos de misturas bin?rias, obteve-se o melhor resultado para a combina??o cimento-res?duo, que foi de 14% de cimento incorporado no res?duo

Much research has been carried out both by academia and the productive sector, sometimes reintroducing them in the same production line that generated them, sometimes in areas unrelated to their generation, as in the production of concrete and mortar for the construction, for example, but each one in an isolated way. In this research, the aim is to study the combined incorporation of the waste drill cuttings of oil well and the residue of the polishing of porcelain, generated in the final stage of finishing of this product in a clay matrix, for the production of red pottery, specifically bricks, ceramic blocks and tiles. The clay comes from the municipality of S?o Gon?alo, RN, the drilling waste is from the Natal basin, in Rio Grande do Norte, and the residue of the polishing proceeds from a ceramic porcelain of the State of Para?ba. For this purpose, we used a mixture of a plastic clay with a non-plastic, in a ratio of 50% each, settling formulations with the addition of these two residues in this clay matrix. In the formulations, both residues were incorporated with a minimum percentage of 2.5% and maximum of 12.5%, varying from 2.5% each, in each formulation, which the sum of the waste be no more than 15%. It should be noted that the residue of the polishing of ceramic porcelain is a IIa class (not inert). The materials were characterized by XRF, XRD, TG, DTA, laser granulometry and the plasticity index. The technological properties of water absorption, apparent porosity, linear shrinkage of burning, flexural tensile strength and bulk density were evaluated after the sintering of the pieces to 850 ?C, 950 ?C and 1050 ?C, with a burning time of 3 hr, 3 hr and 30 minutes, and 3 hr and 50 minutes, respectively, with a heating rate of 10 ?C/minute, for all formulations and landing of 30 minutes. To better understand the influence of each residue and temperature on the evaluated properties, we used the factorial planning and its surfaces of response for the interpretation of the results. It was found that the temperature has no statistical significance at a 95% of reliability level in flexural tensile strength and that it decreases the water absorption and the porosity, but increases the shrinkage and the bulk density. The results showed the feasibility of the desired incorporation, but adjusting the temperature to each product and formulation, and that the temperatures of 850 ?C and 950 ?C were the one that responded to the largest number of formulations / A ind?stria de produ??o de porcelanatos para uso na constru??o civil e a do petr?leo, na fase de explora??o e produ??o, exercem um papel importante na produ??o de res?duos. Muitas pesquisas t?m sido realizadas tanto pela academia quanto pelo setor produtivo, ora reintroduzindo esses res?duos na mesma linha de produ??o que os gerou, ora em setores alheios ao de sua gera??o, como na produ??o de concretos e argamassas para a constru??o civil, por exemplo, mas cada um de forma isolada. O objetivo desta pesquisa ? estudar a incorpora??o combinada do res?duo de cascalho de perfura??o de po?o petrol?fero e do res?duo do polimento do porcelanato, gerado na fase de acabamento final do produto, numa matriz argilosa, para a produ??o de cer?mica vermelha - especificamente tijolos, blocos cer?micos e telhas. A argila utilizada ? oriunda do munic?pio de S?o Gon?alo do Amarante, RN; o res?duo de perfura??o, da bacia potiguar, no Rio Grande do Norte; e o do polimento ? de uma cer?mica de porcelanato do Estado da Para?ba. Utilizou-se a mistura de uma argila pl?stica com uma n?o pl?stica, numa propor??o de 50 % de cada uma (que ? o percentual de mistura adotado na cer?mica fornecedora dessa argila), estabelecendo-se formula??es com a incorpora??o dos dois res?duos nessa matriz argilosa. Nas formula??es, os dois res?duos foram incorporados com um percentual m?nimo de 2,5 % e m?ximo de 12,5 %, variando-se em 2,5 % cada um, em cada formula??o, de modo que a soma dos res?duos fosse no m?ximo 15 %. ? oportuno registrar que o res?duo do polimento do porcelanato ? de classe IIa (n?o inerte). Os materiais foram caracterizados por FRX, DRX, TG, DTA, granulometria a laser e pelo ?ndice de plasticidade. As propriedades tecnol?gicas de absor??o de ?gua, porosidade aparente, retra??o linear de queima, tens?o de ruptura ? flex?o e massa espec?fica aparente, foram avaliadas ap?s a sinteriza??o das pe?as a 850 ?C, 950 ?C e 1050 ?C, com ciclo de queima de 3 h , 3 h e 30 min e 3 h e 50 min, respectivamente, com taxa de aquecimento de 10 ?C/min. e patamar de 30 min., para todas as formula??es. Para melhor compreender-se a influ?ncia de cada res?duo e de cada temperatura nas propriedades avaliadas, utilizou-se o planejamento fatorial e suas superf?cies de resposta para interpreta??o dos resultados. Verificou-se que a temperatura n?o tem signific?ncia estat?stica no n?vel de 95 % de confiabilidade na tens?o de ruptura ? flex?o e que ela diminui a absor??o de ?gua e a porosidade, mas aumenta a retra??o e a massa espec?fica aparente. Os resultados mostraram a viabilidade da incorpora??o pretendida, adequando-se a temperatura a cada produto e cada formula??o, e as temperaturas de 850 ?C e 950 ?C foram as que atenderam ao maior n?mero de formula??es
