Method of servicing high temperature wells

Abstract

A method of servicing high temperature wells. A cooling chamber is secured in end to onto a wellhead of a high temperature well. A hot tubing string is raised from the high temperature well into the cooling chamber. A cooling fluid is injected into the cooling chamber to cool the hot tubing string prior to handling.

1 . A method of servicing high temperature wells, comprising:
 securing a cooling chamber onto a wellhead of a high temperature well;   raising a tubular member from the high temperature well into the cooling chamber;   injecting a cooling fluid into the cooling chamber to cool the hot tubing string prior to handling.   
     
     
         2 . The method of  claim 1 , wherein the cooling chamber is defined by a stack of spools attached in end to end relation onto the wellhead. 
     
     
         3 . The method of  claim 1 , wherein the tubular member has a temperature of at least 100° C. prior to entering the cooling chamber. 
     
     
         4 . The method of  claim 1 , wherein the tubular member is cooled to a temperature of less than 50° C. in the cooling chamber. 
     
     
         5 . The method of  claim 1 , wherein the tubular member is continuously raised through the cooling chamber. 
     
     
         6 . The method of  claim 1 , wherein the cooling chamber has a cooling fluid input and a cooling fluid output for circulating cooling fluid through the cooling chamber. 
     
     
         7 . The method of  claim 1 , wherein injecting the cooling fluid comprises maintaining the pressure of the cooling fluid in the cooling chamber at a pressure that avoids overbalancing the well. 
     
     
         8 . The method of  claim 1 , wherein the cooling fluid is in direct contact with the tubular member. 
     
     
         9 . The method of  claim 1 , wherein the tubular member is raised during a snubbing operation.
