Coiled-Tubing Fluid-Lubricant Composition and Related Methods

Abstract

A method for performing a coiled-tubing process, the method having the steps of performing a coiled-tubing process using a fluid-lubricant composition that includes: a sulfurized component, and a chlorinated component, wherein the sulfurized component is a sulfurized C8 to C14 olefin, wherein the chlorinated component is a chlorinated fatty ester, a chlorinated paraffin, or a chlorinated olefin; and introducing the fluid-lubricant composition into a subterranean wellbore casing.

1 . A method for performing a coiled-tubing process, the method comprising the steps:
 performing a coiled-tubing process using a fluid-lubricant composition that includes:
 i) a sulfurized component, and 
 ii) a chlorinated component;
 wherein the sulfurized component is a sulfurized C8 to C14 olefin; 
 wherein the chlorinated component is a chlorinated fatty ester, a chlorinated paraffin, or a chlorinated olefin; and 
 
   introducing the fluid-lubricant composition into a subterranean wellbore casing.   
     
     
         2 . The method of  claim 1 , wherein the fluid-lubricant composition also includes an emulsifier component. 
     
     
         3 . The method of  claim 2 , wherein the emulsifier component is a polyethylene glycol or a polyethylene glycol ester. 
     
     
         4 . The method of  claim 1 , wherein the fluid-lubricant composition reduces the friction generated by steel sliding against steel surfaces by at least 40%. 
     
     
         5 . The method of  claim 1 , wherein the sulfurized component is a sulfurized (22% S) C9 olefin, a sulfurized (35% S) C9 olefin, a sulfurized (20%) C10 olefin, a sulfurized (38%) C10 olefin, a sulfurized (18% S) C12 olefin, a sulfurized (28% S) C12 olefin, a sulfurized (16% S) C14 olefin, or a sulfurized (25% S) C14 olefins. 
     
     
         6 . A method for performing a coiled-tubing process, the method comprising the steps:
 performing a coiled-tubing process using a fluid-lubricant composition that includes:
 a chlorinated fatty ester, a chlorinated paraffin, or a chlorinated olefin; and 
   introducing the fluid-lubricant composition into a subterranean wellbore casing.   
     
     
         7 . The method of  claim 6 , wherein the fluid-lubricant composition also includes an emulsifier component. 
     
     
         8 . The method of  claim 7 , wherein the emulsifier component is a polyethylene glycol or a polyethylene glycol ester. 
     
     
         9 . The method of  claim 6 , wherein the fluid-lubricant composition reduces the friction generated by steel sliding against steel surfaces by at least 40%.
