Method in an oil and/or a gas production system

Abstract

A method in an oil and/or a gas production system including a plurality of oil and/or gas wells and parameter testers adapted for oil and/or gas production parameter testing. The method is adapted to compare a plurality of options related to the oil and/or gas throughput in the oil and/or gas production system. A plurality of parameter samples are drawn from a parameter distribution. A performance measure is generated for each parameter sample by using the parameter sample and a characterizer for each of the options. An aggregated performance measure is generated for each of the options by using the performance measures.

1 . A method in an oil and/or a gas production system comprising a plurality of oil and/or gas wells and parameter testers adapted for oil and/or gas production parameter testing, wherein said method is adapted to compare a plurality of options related to the oil and/or gas throughput in the oil and/or gas production system, said method comprising:
 drawing a plurality of parameter samples from a parameter distribution;   generating, for each parameter sample, a performance measure by using said parameter sample and a characterizer for each of said options, and   generating an aggregated performance measure for each of said options by using said performance measure, said parameter distribution is generated by using historical and/or online measured and/or estimated data obtained from the oil and/or gas production system.   
   
   
       2 . The method according to  claim 1 , wherein said parameter distribution and the generation of the performance measure are obtained by a statistical analysis. 
   
   
       3 . The method according to  claim 1 , wherein said aggregate performance measure for each of said options are used to select an optimal option. 
   
   
       4 . The method according to  claim 1 , further comprising:
 generating at least one aggregation of said at least one aggregated performance measure.   
   
   
       5 . The method according to  claim 4 , wherein said aggregation comprises a reference to at least one option or characterizer. 
   
   
       6 . The method according to  claim 5 , wherein a routing valve is manipulated using said reference to at least one option or characterizer. 
   
   
       7 . The method according to  claim 1 , wherein said parameter testers adapted for oil and/or gas parameter testing comprise a test separator. 
   
   
       8 . The method according to  claim 1 , wherein at least one characterizer of said options comprises information that a specific well should be tested. 
   
   
       9 . The method according to  claim 1 , wherein at least one characterizer of said options comprises information on the availability of a flow measurement device. 
   
   
       10 . The method according to  claim 1 , wherein at least one characterizer of said options comprises information on using of a test separator, or measurement of flow rate, pressure, temperature, fluid composition, gas-oil ratio, or water-oil ratio. 
   
   
       11 . The method according to  claim 1 , wherein said performance measure reflects the value associated with the oil production rate, oil production volume, profit rate, profit or expenses, or any combination thereof. 
   
   
       12 . The method according to  claim 1 , wherein said aggregated performance measure is generated using the average value of a plurality of performance measures for said option or characterizer. 
   
   
       13 . The method according to  claim 1 , wherein said aggregated performance measure is generated using the average value or sum value of said performance measures. 
   
   
       14 . The method according to  claim 1 , wherein a testing of a well obtains information of the content of water, oil and/or gas. 
   
   
       15 . The method according to  claim 1 , wherein a reference to at least one option or characterizer is presented to the user. 
   
   
       16 . The method according to  claim 1 , wherein said parameter testers adapted for oil and/or gas parameter testing comprise a multiphase flow measurement device. 
   
   
       17 . A computer program product, comprising:
 a computer readable medium; and   computer program instructions recorded on the computer readable medium and executable by a processing unit in a computer based system, for carrying out a method in an oil and/or a gas production system comprising a plurality of oil and/or gas wells and parameter testers adapted for oil and/or gas production parameter testing, wherein said method is adapted to compare a plurality of options related to the oil and/or gas throughput in the oil and/or gas production system, said method comprising:   drawing a plurality of parameter samples from a parameter distribution;   generating, for each parameter sample, a performance measure by using said parameter sample and a characterizer for each of said options, and   generating an aggregated performance measure for each of said options by using said performance measure, said parameter distribution is generated by using historical and/or online measured and/or estimated data obtained from the oil and/or gas production system.
