Kharyaga field is a complex karstified carbonate reservoir located in a harsh arctic environment of Timan Pechora region on the North of Russia. The main Kharyaga reservoir, still under development, is subdivided on several layers and is characterized by an important heterogeneity (spacial distribution, fractures, karstified areas, etc.) leading to a very complex flow distribution in the reservoir (sweep efficiency) as well as in the well (water breakthrough, possibility of cross flow). In addition, the oil of this reservoir is waxy crude with high positive appearance pour point temperature.

High dynamic data quality and adequate real time follow up is mandatory for proper reservoir behavior understanding and characterization in order to be able to take effective operational decisions in due time and then maximize production level. Estimation of each layer contribution to the overall production allows proactive reservoir management including real time follow up and well intervention planning.

Fiber optic systems were installed as a part of the upper completion system below ESP in front of perforated interval. Each development pad is equipped with permanent DTS (Distributed Temperature System) to acquire temperature traces data in selected wells. An innovative system was implemented in order to ensure temperature traces acquisition, transfer and storage in real time to Moscow office, which allows reservoir engineer to interpret in real time and upon operational request any variation (well rate, watercut increase, Wax deposition evolution along the well, etc…) and take well-informed decision. This new procedure allowed to reduce drastically the time needed to integrate temperature information thanks to human interference reduction in the data transfer and data storage. Real time qualitative interpretation, thanks to real time data, allowed curative program and improving scrapping frequency leading to production gain.

We suggest a brief discussion after the presentation - How to build a career within operating company.
