Multiphase pumps for oil-water-sand-gas mixtures

Wednesday, September 19th, 2018 von admin

The global hunger for oil and gas continues unabated, which means that exploration companies are striving to achieve higher and higher yields and are also increasingly developing difficult sources, such as heavy oils with an extremely high solid content. Methane from coal seams or highly viscous oil at more than 10,000 mPas are already of commercial interest today but are just as complicated to extract as oil-sand mixtures from the Sudanese desert. Conveying systems in particular have to be adapted to the media and the environment if production is to be efficient under such conditions. Netzsch Pumps & Systems has developed a multiphase pump precisely for this area of application. It can handle mixtures of oil, water and gas along with sand content, achieving flow rates of up to 600 m³/h.

Downhole progressing cavity pump with submersible drive

A German energy supplier had initially used a geological horizon for gas storage, but then decided to extract crude oil from the same deposit. Therefore, a suitable extraction system had to be acquired for transporting the multi-phase mixture with a high gas content to the surface from 1,200 m below. Due to the extreme conditions, a special pump technology was required:

Netzsch developed a progressing cavity pump system with submersible drive. As all moving parts are positioned deep down in the well, there is also no risk of environmental impact from leaks at the surface. (more…)

Multiphase pump installation allowing wells to come back to production

Wednesday, November 15th, 2017 von admin

Crosbys Creek Oil & Gas  LLC, based in Ridgeland, MS,  is an independent American producer producing in Choctow County in Northern Alabama, USA. These fields are older and have produced oil and gas for many years.  Over time the natural reservoir pressure has dropped off to a point where some wells are not able anymore to overcome the back pressure generated by the surface flow lines and the first stage separator of the process facility. The company had heard about multiphase pumping. This economic alternative caught the interest of the management as the production was expected to remain interesting for years to come.

Lewa: Safe pumping of sour crude oil

Thursday, May 7th, 2015 von admin

SauerölpumpeCritical applications of conveying mixtures of acidic hydrocarbon/water to the washing system are a challenge for any pump manufacturer. This was also the case in one recent project Lewa handled in the Emirate of Abu Dhabi. Lewa have designed and supplied 16 pumps to a major construction company in Abu Dhabi specifically designed to handle this critical application. Two processes required to pump

  • liquid hydrocarbons from the flare knock-out drum or the blow-down drum respectively and
  • convey the acidic hydrocarbon/water mixture back into the oil line to the washing system

Since the differences in these two processes are only minor, it was possible to supply 16 mechanically identical pumps of the Ecoflow series, driven by 55 kW electric motors.
