Russian oil and gas companies rebuild and look for effective approaches and technologies to continue their activities under sanctions pressure in 2022. Many companies in the oil and gas sector are currently working on the systematic replacement of imported equipment and software. Telemetry measurements and logging while drilling (LWD) is one of the areas, where oil and gas industry dependend on foreign technologies and equipment. Horizontal wells drilling allows Rosneft to maintain the level of hydrocarbon production at a high level and remain one of the main taxpayers of the Russian Federation. The transition from imported equipment to domestic (or equipment of "friendly countries") does not happen simultaneously, companies need some time. This work is carried out everywhere with local developers and suppliers.
Rosneft Oil Company annually drills more than 3,000 horizontal wells and horizontal sidetracks. The number of wells with a complex design (multi-latteral) is constantly growing; the diversity of the geology of the target formations is increasing. It is very important for the company to maintain the variability of the logging while drilling programs for effective geological support of well drilling and to obtain the maximum amount of geophysical information. In this situation, the fast adaptation of the current plans and LWD programs to the changed conditions comes very important. In this regard, this article will describe several examples of the use of the new industry indicator Geosteering Difficulty index (GDI) of wells when adjusting current plans for directional drilling or LWD programs.
