The multiphase fluid produced from many oil and gas wells is composed of varying ratios of oil, water, gas and in many cases, small amounts of sand and paraffin. Traditional multiphase fluid transfer involves the use of separation equipment and compressors at the wellsite or satellite to separate the oil, water and gas. The gas can be flared off and the separated fluids are then transferred via multiple pipelines, barges or trucks to a central processing station.

Many older wells' gas-to-liquid ratios have increased over the years causing production to become marginal. The costs to install, operate and maintain the traditional multiphase fluid transfer equipment may not be justified by the production from the well or field.

Recently, efforts have been made to develop pumps capable of handling multiphase fluids. However, results indicate that most types of pumps are restricted by their inability to automatically adjust to rapidly fluctuating gas-to-liquid ratios. They can't handle sand or other solids in suspension or efficiently pump fluids with varying API gravities. Many have a tendency to emulsify the fluid making separation much more difficult.

Prompted by a market need for a more efficient multiphase fluid transfer solution, Moyno, Inc. developed the breakthrough Moyno® Tri-Phaze System. Its patented progressing cavity design effectively pumps oil, gas and water from the wellsite or satellite through a single pipeline to a remote processing station without degradation or emulsification of the fluids. It effectively transfers multiphase flows up to 29,000 BFPD at differential pressures up to 300 psi.

By significantly lowering wellhead pressures, the Moyno® Tri-Phaze System has been proven to increase production of even marginal wells. Furthermore, it can handle high gas void fractions, high sand cuts and changes in API gravity.
