Patent number: 8459356Abstract: A well treatment composition comprises a surfactant comprising a substituted ethoxylated phenol having at least one substituent, 1 to 14 moles of ethylene oxide, and the substituent being an alkyl, alkene, or alkyne with a carbon chain length in the range of 4 to 25, wherein the substituted ethoxylated phenol is selected from the group consisting of: ortho-, para-, or meta-substituted ethoxylated phenol; cardanol ethoxylate; derivatives thereof; and combinations of any of the foregoing. Preferably, the surfactant comprises cardanol ethoxylate, a substituted cardanol ethoxylate, and derivatives thereof. A method of cementing in a subterranean formation comprises: introducing a cement composition into the subterranean formation, wherein the cement composition comprises: (A) cement; (B) water; and (C) the surfactant; and allowing the cement composition to set.Type: GrantFiled: December 13, 2012Date of Patent: June 11, 2013Assignee: Halliburton Energy Services, Inc.Inventors: Abhijit Tarafdar, Trissa Joseph, Vineet Vasant Sathe

Patent number: 8394191Abstract: A cementitious composition including cement, water, and a rheology modifying additive (RMA) is provided. The inclusion of the RMA improves the cementitiuous composition's response to vibration, and dampens out differences due to minor fluctuations in initial slump of the composition. The RMA may include a dispersant for cementitiuous compositions. The cementitious composition may optionally include other admixtures or additives known in the industry. A method for making the cementitious composition is also provided.Type: GrantFiled: December 5, 2007Date of Patent: March 12, 2013Assignee: Construction Research & Technology GmbHInventor: Jeffrey R.
