We have an order to deliver 10 off esmerDual MPFMs to be used as fixed installations at the OGMs at Thar Jath and Mala Fields operated by Sud Petroleum Operating Co. (SPOC).
PSL has today announced the launch of its new MPFM and digital platform. esmerDual ™ comprises a cone that also acts as an impedance electrode. Physical properties (including GVF) are estimated by PVT modelling and tune up methodology developed by PSL. esmerDual is suitable for all fluid types and flow regimes (full watercut and GVF cover). For transmitters, esmerDual comprises a standard multivariable transmitter and a proprietary impedance circuit. For fitting, esmerDual can be dropped into the process line horizontally (light and compact). For wiring, a single RS485 digital cable is required between the field unit(s) and the PC in the control room (many-to-one). Calibration, processing and I/O tasks are carried out locally on the PC by esmerDigital ™ software. I/O tasks (including network connection for output) are implemented on the RS485- Ethernet- Modbus platform. The combination of esmerDual and esmerDigital reduces field electro-mechanics to a minimum. With esmerDual and esmerDigital, a multiphase flow meter per well (multiple wells) connected to the company network is in the realm of reality.
We gave two presentations at this annual conference - exhibition:
PVT - EOS Modelling in Multiphase Flow Metering: This was about diminishing returns of gamma ray densitometry and how EOS modelling can provide equivalent functionality for less money and greater reliability.
Project Experience in Large Scale Implementation of MPFMs in an Entire Oil Field: This was yet another lecture by PSL about “dos and donts” of MPFMs, lessons learned from field experience.

Finally, the big moment has arrived and passed ! Too quickly in our opinion. Many thanks to everyone visiting our stand - and there were indeed more of you than expected. It was a great pleasure meeting you all and showing you live on our stand world’s best and one-and-only gas-liquid metering system esmerGL and the remote control/display web application esmerWebApp. Look forward to meeting you all again in the near future.
PSL has presented a paper jointly with Gazpromneft Badra BV at the SPE Conference in Moscow. The paper is entitled Multiphase Flow Metering – A Case Study from Badra Oil Field
Petroleum Software Ltd is taking part in the MultiFlowMet II JIP which is coordinated by TUV NEL and supported by The European Metrology Programme for Innovation and Research – EMPIR. A number of leading MPFM suppliers and multiphase flow laboratories are taking part in the new JIP which is a follow up to the preceding EMRP project ENG58 at which a small reference network (of three laboratories) was established based on a single multiphase metering technology. MultiFlowMet II will expand the reference network itself and incorporate a wider range of industrially-relevant flow conditions that are proven across a more representative range of field- deployed MPFM technologies.
PSL has presented its latest multiphase flow meter model esmer D2+ at the Iran Oil Show (21st international Oil and Gas Show 5-8 May 2016). The show, held at an exhibition park at the center Tehran, was better attended this year. The lifting of the sanctions has given an uplift to the exhibition. We have noticed a larger number of international exhibitors this year. Discussions with NIOC engineers who have visited our stand have confirmed that projects which had stalled in recent years will be revived during 2016.
PSL engineers were at Badra Iraq at the beginning of February to validate the well head MPFMs (17 off) against a mobile 3-phase horizontal test separator. As with all measuring instruments, inline MPFMs need to be proven at intervals. In the case of MPFMs it is more practical to do the job in-situ and a conventional horizontal gravity separator is best suited for the task. Thus, the provision of a conventional separator was included in the project scope from the beginning at PSL’s initiative. According to the present project plan, the operator will take direct responsibility for use of the mobile separator for the validation and in-situ calibration of the MPFMs instead of relying on a third party well test service company as per usual practice. This would permit a regular test plan to be put in place. The separator, manufactured by China Oil HBP Science & Technology (http://www.china-hbp.com), was designed to handle maximum flow rates of up to 18,000 bpd /day of oil and 20mmscfd of gas at a maximum pressure of 43 bar and 120C. Care was taken for optimizing the size of the vessel to achieve mobility between 17 well heads. Despite such care, weight of the separator assembly is 38 tons empty / 57 tons’ full frame dimensions are: 12.5m (L) x 3.6m (W)x 6m (H)). A size worthy of attention but the lifting gear and the trucks were more than a match for the challenge. The separator was lined up in series with MPFMs and measurements were carried out simultaneously and compared. MPFMs were seen to be performing within design uncertainty limits.
Readers of this column will be aware that PSL has delivered twenty ESMER MPFMs to Gazprom’s Badra Field since 2013. Drilling is ongoing at the field and MPFMs are being brought on line in stages as new wells are completed. Another MPFM has just been brought on line in December, bringing the total number of MPFMs commissioned to 7, still a little short of half way mark!
esmer C2+ system was delivered to IOOC for installation on a new wellhead platform constructed within the scope of the Foroozan Field Development Project. The FOROOZAN complex is located in Iran and Saudi Arabia border, 110 KM from KHARG Island. ESMER C2+ MPFM will be used for well testing purposes.
Further deliveries of esmers have been made to the Badra Oil field bringing the total supplied since October 2013 to 17 off 6” well head MPFMs and three off 14" production line MPFMs. The operator is Gazprom and contractor is CPPMec.NOVEMBER 2013 Petrol Kuyuları Sistemleri Ticaret ve Sanayi A.Ş.

esmer WIO Meter measures the flow rates of individual phases in two-phase oil-water production lines which remain in the oil continuous phase (*). esmer WIO is based on a cone differential meter which also acts as a capacitance sensor.
(*) esmer WIO measures oil-water mass flow rate as well as water composition.
esmer WIO works in the range 0-50% water cut and can tolerate up to 5 % GVF within its accuracy specification. esmer WIO is particularly suitable for use in production lines and in the liquid leg of separators. Effect of oil density and temperature is taken into account in the factory calibration of the meter. Field measurements are automatically compensated for changes in oil density and temperature Salinity does not affect the measurement made by esmer WIO Meter – which is based on the characterisation of the dielectric property of the fluid.
esmer WIO field unit makes two primary measurements which are combined in the flow computer to provide the oil flow rate in mass or volumetric units. The primary measurements are those of dielectric constant (water composition) and differential pressure across the cone (mass flow rate).

Petroleum Software has announced today that it has successfully commissioned six esmer V2 multiphase flowmeters at the Thar Jath oil field in Sudan operated by White Nile Petroleum Company (WNPOC). The meters were installed and made operational in May 2006 and have been running trouble free to date. With its robust straight through electromechanical design and state-of-the-art technology founded on simple sensors and neural net based software, esmer was an ideal fit for the new Thar Jath development which is located in the south of Sudan. esmer was a good fit for WNPOC's requirements for another reason; the operator wanted a flow meter which did not employ radioactive sensors.
esmer V2 at Thar Jath
As part of the site acceptance testing well tests were conducted at each one of the six gathering stations where esmer meters of identical design are installed. A total of 24 wells were tested at intervals over a period of three months to date. It has been observed that the mass balance obtained from measurements carried out by six esmer meters agreed with the total production measured at the Central Processing Facility to within 10% despite the fact that there were large variations in total production over this period. It is also worth noting that this accuracy was achieved without any tuning or adjustments to the factory calibration of the meters.SEPTEMBER 2006 Petroleum Software Ltd signs technology licence with Siemens
Siemens has awarded a technology licence to Petroleum Software Ltd for manufacturing flow through electrode capacitance sensors based on active shield technology developed by Siemens. The technology is particularly suitable for use in multiphase measurement applications due to its fast response times. esmer neural nets use features extracted from the capacitance electrodes at high frequencies to determine water composition in the presence of gas across the full GVF and water composition range.AUGUST 2006 ESMER V6 Tested at NEL Wet Gas Loop
