Well Logging

Well logging is the main way of acquiring information about the oil field throughout its lifecycle, from estimation of reserves to development planning, drilling and exploitation. Without well logging, there is no way to prove geologists’ assumptions of oil presence and reservoir potential, or to make the best decisions during completion and development operations.

Gazpromneft STC provides planning, support, interpretation and analysis of data acquired in the course of geophysical well logging (GWL), production well logging (PWL) and well test (WT) operations across all producing assets of Gazprom Neft. These include over six thousand operations per year. GWL helps identify producing intervals in a formation and determine their oil saturation at well completion stage, PWL — at well operation stage, and WT helps evaluate reservoir properties.

STC pursues to mainstream new technologies at all stages of well logging operations, from experiment design to post-processing of data interpretation results. New equipment and measurement instruments are being tested all the time to support the increase in the number of high-tech wells at Gazprom Neft and boost their performance. Logging data interpretation techniques and algorithms are being constantly improved with a focus to ultimately use 100% of data acquired during normal well operation. STC also develops its own software used to acquire, process and analyze well logging data.
