Description: MCOT is a novel multiphase oil well tester algorithm which enables the calculation of an unseparated emulsion’s oil, water and gas components over certain ranges of WC and GVF flow regimes. The use of a GLCC bulk degasser greatly expands MCOT’s GFV operationing range.

Benefits: Lower cost, smaller footprint, low weight, multiphase meter, employing conventional hardware technology.

Sibex International Inc. (Sibex) presents two novel variants of its potentially game-changer MPFM solutions implemented through its mass-fractions-based, IP-registered Multi-Component Oilwell Tester (MCOT) technology.

The MCOT 4 DP variant employs a Coriolis MPM together with a differential pressure (DP) Meter.

The basic differences between MCOT 4 DP variant and other, similar MPFM solutions are:

MCOT 4 DP solutions are low-cost well-test measurement solutions with high reliability, repeatability and virtually zero field maintenance. MCOT 4 DP solutions are flow-through, 0% GHG emission, no radioactive isotope, no complex cross correlation technology, which provide for the monitoring, trending and anomaly detection of the produced oil, water and gas components in near-R.T., depending on the user’s DAC system’s sampling cycle.

Variant MCOT 4 DP Vis is a unique, in-situ, field-calibratable system. The Proof of Concept (PoC) tests indicate that this solution’s oil, water and gas component errors are comparable with the errors of the conventional oil well test separator. For set-up, the densities and viscosities of pure components (measured or calculated) shall be required at Po, To.
Variant MCOT 4 DP algorithm yields potentially allocation-quality component errors, but the Coriolis MFM (or it’s parelled twin) must be uninstalled and be sent to a MPFM lab if re-calibration is required, to measure and record the DP readings across the Coriolis of the pure, separated oil water and gas component flows at the well’s Po, To.

Please note: the PoC tests were conducted at Coanda R & D labs in Burnaby, BC, Canada, a professional organization employing an assembled-for-purpose MPFM test setup.

When the produced well emulsion exceeds a certain, Coriolis-determined %GVF limit (estimated at 15%GVF), the Coriolis must be installed into the liquid leg of a vertical, small footprint, flow-through type bulk degasser, such as an inline, gas/liquid cylindrical cyclone (GLCC) solution. The total gas shall be the bulk gas on the top of the GLCC plus the calculated under-carry gas.

Sibex is looking for a knowledgeable partner, to participate in the testing of a prototype of MCOT at a global industry-recognized MPFM test facility or in the field, where accurately measured, R.T component flowrate data is available.

Sibex would be interested in an on-line session to discus details.
