Saudi Aramco's 'EXPEC research center has announced successful field testing of a 'downhole drilling microchip.' The device is a low cost combination of sensors and data recorder that can be injected into the drilling mud, recording mud pressure and temperature as it circulates down the drill string and back up to the surface.Aramco's 'drill pill' has been developed in a four-year joint program between EXPECand Tulsa University's drilling research project (TUDRP). The idea developed when Aramco's Shaohua Zhou met up with TUDRP associate director Mengjiao Yu at a meeting of the Society of Petroleum Engineers. Zou explained, 'Our idea was for low-cost downhole data acquisition system that could help optimize mud and cement formulations while drilling and reduce data acquisition cost.'
