The emulsifier comprises (1) a carboxylic acid terminated fatty amine condensate or (2) a modified tall oil or (3) a blend of (1) and (2) that is converted to its alkali or alkaline earth metal salt and spray dried.Type: GrantFiled: January 18, 2006Date of Patent: September 4, 2012Assignee: Georgia-Pacific Chemicals LLCInventors: Phillip Wayne Hurd, Gary D. Fultz, Jalandar Y. Jadhav

Patent number: 8252730Abstract: A water-based wellbore treatment fluid contains: one or more viscoelastic-gelling carboxylic acids and/or alkali metal salts thereof; and one or more solubilizing alkylolamines. The carboxylic acids and/or alkali metal salts and the alkylolamines are present in the fluid in respective amounts such that, at 25° C., the alkylolamines solubilize a sufficient portion of the carboxylic acids and/or alkali metal salts to render the fluid viscoelastic. A remaining portion of the carboxylic acids and/or alkali metal salts forms a suspension of solid particulates in the fluid.Type: GrantFiled: February 19, 2008Date of Patent: August 28, 2012Assignee: Schlumberger Technology CorporationInventors: Robert Seth Hartshorne, Trevor Lloyd Hughes, Timothy Gareth John Jones, Gary John Tustin, James Francis Westwood
