Patent number: 10494559Abstract: Cement slurries, cured cements, and methods of making cured cement and methods of using cement slurries are provided. The cement slurries have, among other attributes, improved rheology, such as improved flowability and pumpability and may be used, for instance, in the oil and gas drilling industry. The cement slurry contains water, a cement precursor material and a surfactant having the formula R—(OC2H4)x—OH where R is a hydrocarbyl group comprising from 10 to 20 carbon atoms and x is an integer from 1 and 10. The cured cement have improved strength and density properties due to reduced fluid loss and even placement during curing. The cured cement contains a surfactant having the formula R—(OC2H4)x—OH where R is a hydrocarbyl group comprising from 10 to 20 carbon atoms and x is an integer from 1 and 10.Type: GrantFiled: June 21, 2017Date of Patent: December 3, 2019Assignee: Saudi Arabian Oil CompanyInventors: Abdullah Al-Yami, Hussain AlBahrani, Vikrant Wagle, Ali Safran
