White Well Delivers First Results

The mean time between failures (MTBF) of White Well equipment in one of the Tomskneft wells has exceeded 365 days. White Well equipment has achieved this MTBF level while retaining the declared operating parameters.
The MTBF of equipment in this well increased by more than threefold (Severnoye Field, Well 254, Cluster 2). The average MTBF was previously 120 days. The wellstream is corrosive and contains mechanical impurities.
The equipment packages chosen for these well conditions by Rimera experts as part of the White Well project include sour-service tubing manufactured by Pervouralsk Novotrubny Zavod (part of ChelPipe Group) and modern corrosion- and wear-resistant compression-design pumps manufactured by Alnas plant, the Almetyevsk-based operation of Rimera Group. Tubing hangers are made of a steel grade with 3% chromium content.
"Effective selection, manufacture, and servicing of special-purpose packages of electrical submersible pump units and tubing designed for difficult wells ensures a synchronized increase in mean time between failures for all downhole equipment. This reduces the number of tripping operations and repairs with the attendant costs, translating into higher production volumes. Rimera covers a portion of financial risks involved in the implementation of the White Well project, which now represents a new standard of oil service. This is due to pilot operation of equipment supplied for this project and customer-friendly payment terms whereby customers pay only for actual results," Konstantin Samsonov, Rimera Group Commercial Director, comments on the features of the White Well project.
In addition to this well, Tomskneft is operating one more package of equipment with an MTBF close to 1 year at this point. The White Well project is also underway in two wells of LUKOIL - Western Siberia where the MTBF exceeds the standard level by 30%.
