Abstract: Correct measurements of the water content and crude oil composition are essential for an accurate yield allocation. Especially in the cases of maturing production fields or locations where sand in combination with high water contents can be present, unreliable measurements on the quantity of oil being produced can occur resulting in significant measurement errors. Furthermore, with offshore locations commonly having constrained in electrical power, pipework configurations, and footprint size available, this can be a big issue and challenge. A new mixing method for pipeline sampling was found to cope with these limitations. The new mixing technology, e-Jetmixing, made use of the eductor principle and was tested with the support of Aker BP at the NEL low-pressure multiphase facility. A comparison was made between the e-Jetmixer and traditional jet mixing designs. Tests were performed on oil/water flows up to 65 % water cut by volume. The new and traditional mixing technologies were compared for both horizontal and vertical pipeline configurations. Test results showed that the traditional jetmixer required a high amount of power/energy to reach a homogeneous oil/water mixture and showed the unexpected layering of oil/water at low flowrate regimes. The new e-jetmixing design (with eductor), was tested under the same conditions and reached a homogeneous oil/water mixture with a substantially lower amount of required energy. Furthermore, it was found that the new e-jetmixing design showed a more consistent performance irrespective of the flow conditions, indicating an improvement of the overall measurement uncertainty. We can conclude that the new e-jetmixing design (with eductor) tested at the NEL facility has proven that a substantial reduction in power required and footprint can be achieved, together with more consistent performance. This paper will detail the advancements on the technology, the test work completed at an independent National Measurement Institute facility and describe the benefits it can offer end users.
