Argentina’s Patagonian Plateau, Chaco Plain, and Pampas Grasslands span multiple climate zones. From arid pastures to large-scale farms, stable water sources are always the lifeline for agricultural production and community operations. In recent years, more and more drilling contractors in Argentina have been looking for cost-effective well digging rig alternatives, instead of only choosing traditional European and American brands. YG has delivered many units to multiple provinces in Argentina. Today we share two typical cases, from demand confirmation to actual drilling results, to help you understand the whole process.

Case 1: Ranch Irrigation Drilling Project in Córdoba Province
Customer Requirements: The customer manages a large farm and ranch in Córdoba Province, with nearly 3,000 hectares of ranch land. Due to low rainfall in recent years, water output from the original three shallow wells (around 60 meters deep) keeps dropping. They urgently need deeper water wells to supply livestock drinking water and irrigation water. The target depth is 200–250 meters. The formation mainly consists of sandstone and conglomerate, with local hard limestone layers. The customer has a limited budget and wants reliable water drilling equipment at a reasonable price.
YG Solution: We recommended the YG-200 model. It can drill down to 200 meters with a maximum hole diameter of 305mm. Fitted with a 65–70kW engine and rotary torque of 3500–4800 N · m, it easily handles sandstone and medium-hard limestone. We also offered a screw air compressor package to guarantee enough air volume for cuttings removal at 200 meters depth.
Sales Process: The customer contacted us through our website and compared three suppliers at first. The key turning point was that we shared construction videos taken under similar geological conditions in Argentina and detailed hydraulic system drawings of YG-200. The customer arranged for their technical consultant to check the machine via remote video inspection. Finally, the customer confirmed the order within two weeks, choosing a full package including main rig, spare drill pipes, and two sets of DTH hammers.
Operation Result: Assembly and drilling of the first well started within 15 days after the machine arrived at the port. A stable water vein was found at 220 meters. Daily water yield exceeded 80 cubic meters, fully meeting drinking water for 600 cattle and irrigation for 200 hectares of farmland. The customer reported the drilling speed was about 35 meters per hour, faster than expected. Later, they placed an extra order for a second set of drill pipe assemblies.
Case 2: Deep Water Source Development Project in Río Negro Province
Customer Requirements: The customer is a professional drilling company in Río Negro Province (Patagonia region). They take on government rural water supply projects. The project requires drilling water wells of 350–500 meters in multiple villages. The ground is mainly granite and weathered basalt, one of the hardest geological formations in Argentina. The customer’s two old machines can only reach 200 meters, so they urgently need deep water well drilling machines for deep well and hard rock drilling.
YG Solution: We recommended the YG-400 model with a designed drilling depth of 400 meters. It has a 92kW engine and rotary torque up to 6500–9000N·m, working air pressure reaches 3.5MPa. For hard rock conditions, we selected 102mm drill pipes and heavy-duty DTH hammers to secure impact efficiency and cuttings removal in granite layers.
Sales Process: The customer’s main concern was whether Chinese rigs can maintain stable performance drilling granite in Patagonia. We shared field records of the same series well drilling rig machine working in the Gobi Desert of Mongolia, which also features extremely hard rock. The records included drilling speed data, hammer wear data, and total drilled meters. The customer approved the technical parameters in the end. The contract included warranty terms and a commitment to long-term supply for wear parts.
Operation Result: After YG-400 arrived on site, the average drilling speed reached 28–32 meters per hour in granite formation at 380 meters on the first well. Although slower than sandstone drilling, this performance stands out among machines of the same class. Up to now, 4 deep wells have been finished. The deepest well reaches 470 meters, with a maximum daily water output of 120 cubic meters for a single well.
Well Digging Rig Daily Maintenance Guide
Whether it is the YG well digging rig or other brands of drilling rigs, regular maintenance is the foundation for extending service life and keeping high working efficiency.
- Hydraulic oil — Test oil quality every 500 working hours. Replace it every 2000 hours or once per year. Keep oil temperature below 70°C.
- Drill pipes and joints — Clean threads and apply grease after every use. Replace immediately if deformation or cracks appear.
- DTH hammer — Normal service life is 2–3 years. Listen for abnormal impact noise during operation. A weak sound means inspection is needed.
- Air compressor — Check oil level before daily startup. Replace air filter every 250 hours. Keep the screw air compressor well cooled and clean.
- Hydraulic outrigger cylinders — Check seals for leakage every month. Keep piston rod surface clean.
- Track chassis — Clear mud and stones regularly. Check track tension and drive wheel wear.
