Publication number: 20110062085Abstract: A method for the removal of soluble metal ion contamination from fluids is disclosed. The method includes passing the contaminated fluid through a filter medium comprising a reducing metal and a filter aid, such as diatomaceous earth, and collecting a filtrate with lower concentration of soluble metal ion contamination. The reducing metal can have a reduction potential of from ?0.50 volt to ?3.10 volt and can be capable of reducing the soluble metal ions to insoluble metal, which can then be entrapped in the filter medium or otherwise separated.Type: ApplicationFiled: September 15, 2009Publication date: March 17, 2011Applicant: Halliburton Energy Services, Inc.Inventors: Jay P. Deville, Matthew L. Miller, Stephen W. Almond, Douglas J. Harrison
