Early in November, on the Urievsk oil field, Weatherford completed the first Russian engineering and technical maintenance operations during construction of horizontal well sections with the use of full range of 4 ¾ in. LWD Triple Combo (conventional assembly of three combined logging while drilling sensors).
The operations were conducted by Weatherford Directional Drilling PL specialists. The operations were conducted in the interval of 2961-3430 meters (in vertical section of 2657-2660 meters). While gathering data for processing and interpretation of logging data while drilling (Logging-while-Drilling or LWD), the communication channel for real time data transfer (Weatherford Real Time Solutions WITSML) was successfully operated.
Interpretation of obtained logging data was conducted and delivered to the Customer two times per day. Upon retrieval from the memory unit the data was interpreted utilizing the Interactive Petrophysics software and the final conclusion was provided to the Customer in a form of plot record, report as LAS-files processing with logging data and interpretation results.
The Customer highly appreciated the pilot operation performed. Currently the equipment is ready and Weatherford specialists waiting for commencement of operations on the next horizontal well but on a different field under more complicated drilling conditions.
