Sekhars Correlation between Oil Production Rate and Gas-Lift Rate

Abstract

The relationship between the rate of oil production from a well completion and the rate of gas-lift applied to the well completion can be described through a non-linear equation that uses four regression parameters.

1 . The specific equation that provides the relationship between the rate of oil production from a well completion and the rate of gas-lift applied to the well completion.  
   
   
       2 . The equation in  claim 1  is Q oil =A * (1−e −B*(gl−C) )−D * gl.  
   
   
       3 . Q oil  in  claim 2  represents the rate of oil production.  
   
   
       4 . gl in  claim 2  represents the rate of gas-lift.  
   
   
       5 . e in  claim 2  is the natural log base.  
   
   
       6 . A, B, C, and D in  claim 2  are non-linear regression parameters.  
   
   
       7 . Rate of oil production in  claim 1  is the amount of the simple or complex liquid mixture of hydrocarbons that can be produced from a well completion in a given period of time.  
   
   
       8 . Rate of gas-lift in  claim 1  is the amount of high pressure gas injected into the well completion in a given period of time.  
   
   
       9 . Well Completion in  claim 1  represents the tool assembly in the producing well that provides the liquid mixture of hydrocarbons a flow path.  
   
   
       10 . Producing well in  claim 9  refers to the well through which oil is produced in the fields where improved recovery techniques are being applied.  
   
   
       11 . Well in  claim 10  refers to a hole in the formation of the earth made by a drilling bit for the purpose of extracting hydrocarbons.
