Our Story & Vision

OpenField was launched in 2011 with the goal of making measurement systems based on microchip technology work in the harsh downhole conditions of the Oil & Gas industry. As world demand rises, the energy sector is pushing exploration into unknown territories, requiring faster and more accurate measurements as alternative energy markets develop similar needs for harsh environment monitoring. It was during his 20 year career with O&G world leaders that Eric Donzier realized the great potential of miniaturization to make this continued exploration safer and more productive.
OpenField has become an innovative actor in the instrumentation of harsh environments through continued research and development in micro sensing technology. Our goal is to improve efficiency, reliability, ease of use, and the accessibility of sensing technologies for harsh conditions at the bottom of wells and in emerging energy markets.
