In the course of operations under the rental contract with INK-Service, the DRU4-172RSF motor from Radius-Service demonstrated a high rate of penetration during drilling in the Ayansky (West) licensed block.

The DRU4-172RSF motor delivered superior drilling efficiency compared to conventional motors. The average rate of penetration was 18.82 m/h - 25% above the target ROP.

The gain in the penetration rate saved 8 hours of well construction time.
