HT° prototype under development

Run on e-line, the EZ BHS system is the safest patented single-phase downhole fluid sampling tool available in the market. The oil filled pressure compensation system keeps the system under state of the art PVT considerations from reservoir to surface, thanks to the combination of dedicated piston and regulator that ensure together a controlled sampling rate.
New developments were validated up to 225°C (440°F) in High Temperature Geothermal wells. The 2-1/2” OD sampling system was built for extremely harsh environment, including CO2 and H2S resistance.
The EZ BHS instrument is the only downhole sampling system that allows the lab to analyze the sample in the exact fluid reservoir composition and conditions.
