Caracterização De Rochas Reservatório Por Microtomografia De Raios X

Abstract: RESUMOReservatórios de petróleo são rochas sedimentares com porosidade e permeabilidade suficientes para armazenar e permitir o fluxo de hidrocarbonetos. Testemunhos das rochas reservatório são coletados para a caracterização e obtenção de dados petrofísicos como, por exemplo, porosidade e permeabilidade. Atualmente, a caracterização de rochas reservatório envolve diversas análises como microscopia óptica e/ou eletrônica, medição de porosidade e permeabilidade através de injeção de gás nitrogênio, etc. Estas a… Show more

“…Microstructures can be analyzed threedimensionally by isolating mineral phases for individual analysis. Palombo et al (2015) estimated the porosity of four samples of rocks, being two of limestone and two of sandstone, from the analysis of digital images of X-ray microtomography. Three-dimensional visualization of pore network led the authors to conclusions concerning the form and spatial distribution of the pores, its degree of interconnection and the possible occurrence of a preferred direction for the pores network.…”

“…Therefore, the NT technique is highly desirable in studying oil in mineral samples. Carbonate deposits are one of the main oil and gas reservoirs in the world's most relevant petroleum systems, Calcite and Dolomite are the main constituent minerals of carbonate rocks [1][2][3][4][5][6][7][8][9][10]. The objective of the present paper was investigating the distribution and concentration of the oil EMCAplus® 070, usually employed in permeability experiments to reproduce conditions of natural oil reservoirs [11], in Dolomite, using the NT facility of the Brazilian Institute for Nuclear Technology IPEN-CNEN/SP.…”
