Previous issue date: 2011-02-28 / Petr?leo Brasileiro SA - PETROBRAS / Waste generated during the exploration and production of oil, water stands out
due to various factors including the volume generated, the salt content, the presence of oil
and chemicals and the water associated with oil is called produced water. The chemical
composition of water is complex and depends strongly on the field generator, because it
was in contact with the geological formation for thousands of years. This work aims to
characterize the hydrochemical water produced in different areas of a field located in the
Potiguar Basin. We collected 27 samples from 06 zones (400, 600, 400/600, 400/450/500,
350/400, A) the producing field called S and measured 50 required parameter divided
between physical and chemical parameters, cations and anions. In hydrochemical
characterization was used as tools of reasons ionic calculations, diagrams and they
hydrochemical classification diagram Piper and Stiff diagram and also the statistic that
helped in the identification of signature patterns for each production area including the
area that supplies water injected this field for secondary oil recovery. The ionic balance
error was calculated to assess the quality of the results of the analysis that was considered
good, because 89% of the samples were below 5% error. Hydrochemical diagrams
classified the waters as sodium chloride, with the exception of samples from Area A,
from the injection well, which were classified as sodium bicarbonate. Through
descriptive analysis and discriminant analysis was possible to obtain a function that
differs chemically production areas, this function had a good hit rate of classification was
85% / Dos res?duos gerados durante a explora??o e produ??o de petr?leo, a ?gua se
destaca devido a v?rios fatores, entre eles o volume gerado, o conte?do salino, a presen?a
de ?leo e de produtos qu?micos e essa ?gua associada ao petr?leo ? denominada ?gua
produzida. A composi??o qu?mica dessa ?gua ? complexa e depende fortemente do
campo gerador, pois a mesma esteve em contato com a forma??o geol?gica por milhares
de anos. Esse trabalho tem como objetivo caracterizar hidroqu?micamente a ?gua
produzida em diferentes zonas de um campo localizado na Bacia Potiguar. Foram
coletadas 27 amostras provenientes de 06 zonas (400, 600, 400/600, 400/450/500,
350/400, A) produtoras do campo denominado S e medidos 50 par?mentos divididos
entre par?metros f?sico-qu?micos, c?tions e ?nions. Na caracteriza??o hidroqu?mica foi
utilizado como ferramentas c?lculos de raz?es i?nicas, diagramas de classifica??o
hidroqu?mica sendo eles o diagrama de Piper e o diagrama de Stiff e tamb?m a estat?stica
que auxiliou nas identifica??es de assinaturas padr?es de cada zona de produ??o inclusive
a zona que fornece a ?gua injetada nesse campo para a recupera??o secund?ria de
petr?leo. O erro do balan?o i?nico foi calculado para avaliar a qualidade dos resultados
das an?lises que foi considerada boa, pois 89% das amostras apresentaram erro abaixo de
5%. Os diagramas hidroqu?micos classificaram as ?guas como Cloretadas S?dicas, com
exce??o das amostras da zona A, proveniente do po?o injetor, que foram classificadas
como Bicarbonatadas S?dicas. Atrav?s da an?lise descritiva e da an?lise de discriminante
foi poss?vel a obten??o de uma fun??o que distingue quimicamente as zonas de produ??o,
essa fun??o apresentou uma boa taxa de acerto de classifica??o que foi de 85%
