Abstract:
1. A wellbore effluent analyzing device for downhole analysis of the wellbore effluent, comprising: a main conduit carrying in operation said wellbore effluent; a sample channel communicating through at least one opening with said main conduit; a first phase separation stage, wherein said first phase separation stage is configured to generate a forced flow of a sample of said wellbore effluent through a first phase separation member, and wherein said first phase separation member is configured to allow a pre-determined phase of said flowing sample to pass through said first phase separation member; a second separation stage configured to generate a forced flow of at least part of said pre-determined phase through a second separation member to provide a further separated sample, wherein said second separation member is configured to separate the at least part of said pre-determined phase according to chemical or physical properties; and a sensor unit to detect components of said further separated sample.
