SURFACTANT COMPOSITIONS FOR WELLBORE OPERATIONS, METHOD OF FORMING SAME AND METHODS OF USING SAME |
摘要 |
Surfactant compositions for wellbore operations comprise a first surfactant selected form alkyl polyglycosides having a C4 to C20 alkyl chain and ethoxylated alcohols. Such compositions can be obtained which will form Winsor Type III microemulsions in a water-oil mixture in a hydrophile-lipophile balance range of at least 9.8 to 10.8 at 130 ~F wherein the water may be a chloride brine. Also provided is a method of formulating the composition to have a predetermined solubilization parameter in oil and water and methods of using the compostions in wellbore operations, especially oil and gas well clean out operations, formation acidizing and well cementing operations.
