GEONAVIGATOR DRILLING MANAGEMENT CENTER

GeoNavigator Drilling Management Center (DMC) is the only such asset in Russia’s oil and gas industry offering integrated geological and technological engineering support of high-tech well construction processes in real time.

Gazprom Neft has run the DMC since 2012. It was established following a substantial increase in the number of drilled high-tech wells (horizontal, multi-lateral, multi-branch wells) that resulted from full-scale initiation of development of hard-to-recover reserves and the beginning of development of new major deposits in the Arctic and East Siberia.

Apart from that, construction of high-tech wells is an effective way to stabilize the output at the Company’s existing assets with high depletion rates, which will enable development of new, more complex reserves. Advanced drilling technologies are also used in the development of unconventional reserves, such as the Bazhen oil.

As of year-end 2017, over 62% of all the wells drilled at the Company’s oil fields were high-tech wells. From this perspective, Gazprom Neft is the leader of Russia’s oil and gas industry. GeoNavigator has the capabilities for 24/7 monitoring, control and remote engineering support of construction of more than 800 technologically complex wells at all of the Company’s deposits annually.

GeoNavigator Drilling Management Center enables real-time collaboration of geologists and drilling engineers, as well as continuous support of drilling operations 365 days a year and 24 hours a day.

Data picked up by drill pipe sensors is transmitted live to the DMC, where it is processed by a cross-functional team of engineers. Looking at the continuously updated information on reservoir properties and drilling parameters, DMC operators promptly adjust the drilling parameters and well path and introduce other engineering changes.

After the launch of GeoNavigator DMC, the efficiency of horizontal well drilling through oil-bearing formations increased from 65% to 92%.

Future evolution of the Drilling Management Center will involve introduction of innovative solutions, to include new-generation digital technologies.

Sensors that transmit drilling data are typically located several meters away from the drill bit, and operators who control the well construction process from the DMC acquire information on reservoir conditions with a 20-30 minute lag. This time may be enough for the well path to swerve away from the producing horizon. Addressing potential adverse effects of working in the blind zone is one of the major technological challenges these days.

One of the solutions is to build a self-correcting simulation model that will refer to such parameters as drill bit load, torque, vibration and drilling rate to determine the type of rock around the drill bit in real-time mode. This digital tool will help engineers refine the reservoir model adjust drilling parameters.

Determining the type of rock around the drill bit is not the only application of the simulation model. In the future, it will enable real-time calculation of reservoir productivity, recommend the optimal drilling parameters and even evaluate the economic benefits of drilling through a specific horizon. Additionally, application of this solution will help enhance occupational safety at the Company’s oil fields.
