July 2010 ESMER Water-in-Oil Meter

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).

April 2010 ESMER Mobile

Do you feel that you are you paying too much for well testing services? Are you finding it difficult to operate and maintain a mobile separator? Are you finding it difficult to move around tons and tons of equipment?

We may have just the solution for you. ESMER Mobile is now available for hire. ESMER Mobile is easy to operate. It takes one day to learn to operate ESMER Mobile. Mounted on an off-road trailer complete with its robust and light accesories, ESMER Mobile is easy to transport to the well head. Once at the well head, all that remains is to branch the flexi-hose into the pipeline and click on the start button on the flow-computer hosted inside the portacabin on the trailer

The meter hosted on the mobile skid can be any ESMER MPM selected from the usual range (2" to 6") and enjoys the same advantages of wide range and high accuracy of fixed meters. ESMER MPMs are non-instrusive (no sand trapping problems) and non-nuclear (oil industry standard sensors).

October 2006 ESMER V2 Meters Commissioned at Thar Jath field WNPOC Sudan

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.
