SANGASTECH – High-Precision Inertial Sensors for Extreme Environments

Our downhole pressure gauge deployed in the Middle East suffered an unexpected failure, calling for an urgent replacement of the quartz crystal pressure sensor. Enquiries across multiple suppliers returned a typical lead time of four months, putting the whole project at imminent risk of shutdown. Upon contacting Sangastech, Joyice responded instantly and coordinated production and shipment expeditiously. Within half a month, the goods arrived at the site. The replacement was carried out smoothly and the fault resolved completely. Thanks to such agile support, we successfully avoided heavy losses caused by operational downtime. Our sincere gratitude goes to Joyice and the team.

We weighed carefully between titanium alloy and 17-4PH during material selection. Following Sangastech’s expert recommendation tailored to our downhole conditions, we settled on 17-4PH. Deployed remotely in the Middle East, this thermal flask has operated continuously for six months in sulfur-bearing mud at 168°C. It maintains intact pressure sealing and steady thermal performance without corrosion or leakage. The internal temperature rise of the tool stays within design limits. Field results validate their solid engineering expertise. We are grateful for this practical application guidance.

When designing our hydraulic loops for logging tools , I was troubled by high costs and frequent failures of solenoid valves. Sangastech’s bidirectional plunger pump integrates directional control and eliminates the need for extra solenoid valves, simplifying our hydraulic architecture. It delivers stable flow and pressure in multiple local wells. It cuts component expenditure and reduces downhole failure risks, a highly practical solution.

Cross-border shipment of high-temperature logging lithium batteries has long been a major challenge for our project. We reached out to many suppliers but failed to find a proper solution. Thanks to Sangastech’s mature hazardous cargo shipping capability, they arranged the shipment smoothly. The goods arrived safely at our Oman site, resolving this long-standing logistics dilemma.

During the R&D of our camera stabilized platform, we struggled to balance sensor size and stabilization precision. Previous inertial sensors were either too bulky for the limited enclosure or lacked sufficient stability, resulting in shaky footage. Sangastech’s MEMS gyro delivers remarkable stability for smooth, shake-free imagery in a compact package, resolving our long-standing challenges in mechanical integration and stabilization control.

During the selection of quartz pressure sensors, we carefully evaluated single-crystal and triple-crystal configurations. Following Sangastech’s professional recommendation tailored for long-term static downhole acquisition, we opted for the triple-crystal solution. Although it comes at a higher cost, its stability and resolution exceeded our expectations in field deployment. The quality of long-term downhole data fully meets our strict requirements for well test interpretation, making this choice worthwhile.

When selecting pressure sensors for our long-distance oil and gas pipelines in Kazakhstan, we spent substantial effort comparing silicon resonant and piezoresistive solutions, and negotiated output interfaces with multiple suppliers. We finally chose Sangastech. Their application-oriented advice fits our pipeline conditions with large temperature swings and fluctuating pressure, saving us plenty of time on trial and research. Working with such a professional supplier makes everything far more efficient.
