New Rimera Solutions Pass Quality Tests at Rosneft and Tomskneft Fields

30.04.2014



As part of pilot tests in field conditions, new equipment made by Alnas plant of Rimera Group has operated for 180 days in normal mode, retaining the plant-declared parameters, which is sufficient to pass acceptance tests by oil companies.

The experimental products include two corrosion- and wear-resistant pumps with a special assembly design: with a thrust bearing of the shaft and with a non-thrust bearing that is located inside the piston rod protector. Besides the pumps, acceptance tests were completed successfully on two energy-efficient submersible electric pumps with increased voltage, rated for 32 kW and 45 kW, belonging to 117 mm dimension group.
The new pumps tested in Purneftegaz wells demonstrate enhanced head and energy parameters with an efficiency factor that is 4-5% greater compared to serially-manufactured equivalents, making it possible to reduce electricity costs during production, thereby increasing the efficiency of the production process.
Motors with increased voltage also demonstrated high efficiency. During the operation of the tested electric motors rated for 32 kW and 45 kW in wells of Tomskneft, we recorded a reduction in electricity consumption by 28% and 17%, respectively. The energy-efficiency component of these motors involves using a higher supply voltage, which reduces the operating current by 2 to 2.5 times.
“Finding ways to raise energy efficiency without requiring a great deal of investment is one of the most exciting and challenging tasks for oil companies at the moment. New equipment of Rimera Group has been developed with these particular requirements in mind. Successful test results prove that our solutions live up to the contemporary expectations of petroleum engineering,” says Sergei Sibiriov, Director of the Rimera Group R&D Center.
Mass production of the new equipment has been launched. The major buyers of innovative Rimera products are the leading Russian oil companies Rosneft, Tomskneft, Slavneft, and Tatneft.
