Two filters, Models PPF-5 and PPF-5A, operating as part of Alnas-made pumps have currently reached a mean time to failure of more than 220 days. Operation of the filters has not raised any issues during the pilot tests, and they continue to operate to date.
The new Alnas product has an improved design that reduces hydraulic resistance as the reservoir fluid enters the pump. The bearing assemblies have a special design that rules out overheating and sticking of the bearings, which ensures reliability of the equipment. The bearing assemblies now include fewer parts and feature increased maintainability.
“The wound-wire filters have been developed by Rimera experts as an alternative to Model ZhNSh inlet filters. The first 50 downhole filters made by Alnas were shipped off to Slavneft early this year. They have proven their quality, and I hope that other consumers of our products will take an interest in them,” says Rimera Group R&D Center Director Sergei Sibiriov.
