Scientists from Perm National Research Polytechnic University (PNRPU) have developed a new system for constructing and tracking the trajectory of horizontal well drilling using telemetry. The navigation system for wells has already been patented, tested and is ready for use: PNRPU has concluded a cooperation agreement with the company "Perm Complexes of Navigation and Rotor Controlled Systems".
The system can operate accurately and safely in a well with a diameter of up to 20 cm and at a depth of up to 3-4 km. The coordinates of the bottomhole are entered into it, and a trajectory to the target is laid along critical points. During the drilling process, a device with a fiber optic gyroscope follows the specified route exactly, collects information inside the formation and transmits it in real time to the drilling team above. If there is a deviation from the trajectory or another abnormal situation, a signal is sent to the surface, which allows the drilling team to change the route.
The program of strategic academic leadership "Priority 2030" helped Perm scientists to develop the system.
