Rimera's Almetyevsk-based Alnas has successfully completed pilot tests of its upgraded gas separator model at the wells operated by RN-Purneftegaz, Rosneft's business unit based in Gubkinskiy.

Rosneft Recommends Alnas' Innovation for Serial Production

During the pilot tests the equipment was operating as expected, with both technical and energy parameters in the normal range. The client's representatives signed an act to certify pilot testing success and recommended the innovation to be put into serial production. At present the equipment is in operation.
5М1E series gas separator unit was designed specifically for wells with increased mechanical impurities rate. By canceling the diagonal stage of the supercavitating wheel and trimming the entry blades of the separating drum the designers have eliminated the chance of having the housing cut open by mechanical impurities in maximum wear zones. The separating drum is entered via a convergent-divergent channel, which ensures good separation properties. The movable parts of the new unit are made of hard Ni-resist. The combination of the above design solutions has resulted in equipment with increased MTBF.
Looking back, at the end of last year a new 0215ECNAKI5-200М1-2250 series pump unit also demonstrated acceptance-level performance at Purneftegaz wells in Gubkinskiy. The new pump has been proven to be 7% more power efficient compared to its series-produced counterpart, which will greatly reduce electricity costs incurred in oil production. Following the successful tests, the client recommended Alnas to start serial production of the new unit.
“In 2013 our new equipment sales have reached a 10-year record level, accounting for almost 25% of our total sales, or more than RUR 500 million. This year we are going to keep this up and sell more than RUR 600 million worth of new equipment,” says Sergey Sachenko, Alnas Executive Director.
