Brand Going Global | Made-in-China Downhole Motor Break Through "Difficult Drilling Zones" – DUPT's Customized Technologies Set New Record for 3,015-Meter Horizontal Well
Recently,DUPT's customized downhole motor, with a drilling depth of 3,015 meters in thehorizontal section, helped the customer set a new construction record. With itsstrong technical capabilities, it has won customers' recognition ofMade-in-China!
"NewAbsolute Record"
Inearly 2025, at an oilfield site in a Russian-speaking region, the client'sproject leader fixated on the flickering data monitors. As the drill bitpierced through the 3,015-meter mark, the control center erupted into cheers.This moment signified that DUPT's custom-built Model 4-3/4'' downhole motor hadsuccessfully shattered the regional horizontal well drilling record,establishing a new milestone for Made-in-China drilling equipment in the area!
Ina recent thank-you letter, the client specifically highlighted: "A newabsolute record has been set in the region." Behind this honor liesChina's technological breakthrough in defying geopolitical constraints andboldly venturing into "highly challenging drilling zones" amid globalgeopolitical shifts.
Cross-BorderChallenges Overcome, Strength Recognized
Severalyears ago, the client’s drilling specifications stillexplicitly stipulated: horizontal wells exceeding 1,200 meters must useimported rotary steering systems. Against the backdrop of shiftinginternational supply chain dynamics and a surge in demand for technologicalalternatives, DUPT’s Marketing Center received aninquiry for an "extreme challenge"—requirements forultra-long horizontal section drilling, high torque, and multi-reservoirpenetration, which directly pushed against the limits of existing technologies.
Theclient’s local geological conditions presented a dauntingtest: alternating complex rock formations of contrasting hardness and softness.Riphean carbonate rocks, as strong as armor, alternated with Vendian clasticrocks, as soft as crumble, posing an extremely high risk of wellbore collapse.Additionally, thin and scattered oil reservoirs demanded that the drillingtools achieve the "threading a needle" precision to hit reservoirtargets in ultra-long horizontal wells. This was a severe trial imposed by theclient’s harsh geological conditions.
Facedwith such a market opportunity, the DUPT team took immediate action, with themarketing and R&D departments launching a cross-border collaborative effortto tackle the challenges. Foreign drilling experts repeatedly deduced drillingprocess curves, while R&D engineers conducted multiple rounds of motordesign simulations. Based on the client’s operationalrequirements, they finally developed a customized Model 4-3/4‘’ downhole motor, which wassuccessfully tested.
Insubsequent field verification, this downhole motor demonstrated remarkableperformance in ultra-long horizontal section drilling. It not only solvedproblems such as easy pressure loss and unstable directional control in thehorizontal section but also set a new record for the client’s longest horizontal wellsection with a length of 3,015 meters. With such strength, it earned the client’s recognition ofMade-in-China!
GlobalizationStrategy, A New Energy Silk Road
3,015 meters is not just anumber—it is a yardstick marking China's high-end equipmentbreaking through technological barriers. The conquest of "highlychallenging drilling zones" stands as a brilliant footnote to DUPT'sglobalization strategy, and a testament to the technical depth ofMade-in-China. But the journey does not end here. In the future, we will continueto leverage customized innovation, deepen cooperation with countries along the"Belt and Road," and provide more efficient and greener Chinesesolutions to the global oil and gas industry!
