    摘要: Hydraulic compositions comprising a setting accelerator, a water-soluble cellulose ether having a degree of alkyl substitution of 1.6 to 2.5 which is a water-soluble alkyl cellulose or a water-soluble hydroxyalkyl alkyl cellulose, and water are useful as self-leveling compositions having an excellent self-leveling capability, a minimal change with time of fluidity, and a short setting time, or as cement mortar compositions having a long open time and a short setting time.

    摘要: Surfactant compositions for wellbore operations consisting essentially of a first surfactant selected from the group consisting of alkyl polyglycosides containing alkyl groups containing an odd number of carbon atoms from about 9 to about 13 carbon atoms and a second surfactant selected from the group consisting of alkyl polyglycosides containing alkyl groups containing from about 12 to about 18 carbon atoms and a third surfactant selected from the group consisting of linear ethoxylated alcohols containing from about 8 to 12 carbon atoms and from about 2 to about 8 ethylene oxide groups and a method for formulating such surfactant compositions.
