Wellsite Tests at Purneftegaz Confirm Reliability of Rimera Group’s Alnas Products

29.07.2016



The Alnas plant (part of Rimera Group) has successfully accomplished the field trial of a new-size pump with increased flow passages at Purneftegaz’s Yuzhno-Tarasovskoye oilfield well. The new equipment has been recommended for batch production.

Series 0215 Size 5 pump with a capacity of 20 m3/day with increased flow passages has worked away 180 days in the normal operation mode, retaining the technical and power consumption parameters. It raised no criticism during the operation. The pump keeps running now.

Size 5 pump with a capacity of 20 m3/day based on the floating and compression assembly principles, is Alnas’s new series of high performance pumps to be run in harsh environment. Flow passages increased by 30% for the guide wheel and by 45% for the impeller versus serial equivalents, help to reduce the impact of scaling and solids on the pump performance and increase its mean time before failure. The pump’s design deploys solid two-piece impeller-type stages that help prolong the unit’s service life and cut the costs per unit of produced oil.

“The effective collaboration of engineers and oilfield workers has yielded a new machine that resolves the issue of operating parts plugged with solids and scale at marginal wellsites. The certificate we received confirming the continuous operation through 180 days, proves the high reliability of the pump. Currently, 7 more pumps are running under field trials at various oil companies. The results will help evaluate in more detail the efficiency of using that equipment and market it in an integrated manner,” says Sergey Sibirev, Director of Rimera Group’s R&D Center.
