Oxsensis Ltd. won a bid with the UK governments Technology Strategy Board, worth £400,000, to develop down hole sensor technology with GE Measurement and Control Solutions for the Oil and Gas Sector. There is an un-met need in the Oil & Gas industry for a reliable method to make a high accuracy measurement of pressure and temperature down the length of an oil well. Devices for this type of application must be robust enough for permanent installation and be able to withstand the harsh environment (400°C) with low drift over time. Currently available electronic instruments have a limited lifetime at these elevated temperatures, therefore advanced sensor technology that could operate within this harsh environment would represent an enabler allowing a higher percentage of the oil and gas in the reservoir to be economically extracted.
