A new research report on the use of the tracer dilution technique for the in-situ verification of multiphase flow meters has just been put on-line. The report highlights the potential of this type of approach and recommends how it should be researched and developed.
“The Multiphase Flow Meter report is a literature review on tracer dilution techniques,” says its author Zak Latif, who is NEL’s Section Leader for Erosion and Produced Water. “We found that these techniques have been applied to check flow measurement both in the oil and gas, and geothermal industries. We also found evidence that they may be sufficiently accurate to be used to verify MPFMs in-situ.”
The report is one important output of a larger body of research which is looking at ways in which companies can save costs by using data analysis and other strategies to assess the performance of their meters in the field – removing the expense of taking meters back to the lab for testing.
MPFMs are commonly used for well test, allocation and production management in the oil and gas industry. More recently these devices have been deployed for subsea or other challenging environments where they are not easy to access. As a result, there is a growing need for validating the performance of these MPFMs in-situ.
The Tracer Dilution study assesses applicable tracer dilution techniques and looks at the current and potential market for tracers and associated equipment. It also reviews previous research work and patents in this field.
According to the study, those involved in developing the techniques seem to have anticipated the use of such techniques for MPFMs verification in situ in the future, as both tracer chemistry and sensor developments advance.
“We recommend that a thorough cross-discipline scientific investigation should be done to systematically assess the potential of the techniques for MPFM verification,” Zak says. “Following this, promising techniques should be developed for practical implementation. Issues of implementation under challenge environments should also be investigated.”
