The range of Thermal Manometric Systems (TMS) operated in Rosneft’ Group Entities is quite broad and offered by a considerable number of manufacturers. Every system implemented its own unique data exchange protocol between its underground and on-ground components, which poses relevant limitations in the course of operations justified by the necessity of applying submersible and on-ground blocks of TMS of relevant manufacturer. In practice, upon breakdown of an on-ground block of TMS of certain manufacturer and with zero chance of its substitution (for instance, no warehousing reserve of such on-ground blocks of such manufacturer), an oil producing entity is forced to continue ESP units operation without control over TMS readings, which prevents obtaining and use of on-line information on downhole conditions, which, undoubtedly, triggers the risk of premature failures.
In the framework of the project certain volumes of work were performed for the purpose of development of pilot versatile TMS, and completed pilot production testing of controlled equipment of seven Russian manufacturers. Pilot commercial testing of versatile TMS for ESP units was acknowledged a success.
Ensuring compatibility of TMS supplied to Rosneft, including their control stations, through support of TRANSFER data exchange protocol, provides an opportunity for operation of such equipment in various combinations and without their tying in to specific manufacturer.
The project is of great significance, because at present more than 30 thousand wells of the Company (more than 70%), operated in artificial lifting mode with the use of electrical submersible centrifugal pumps (ESCP), are equipped with submersible telemetric systems (STMS). The Strategy of most of the Company’s Entities is aimed at 100% ESP well stock coverage by STMS.
