Abstract
An untethered sensing object able to sense and record well fluid and wellbore parameters. The untethered sensing object is adapted to transmit recorded data towards a communication module of a toolstring, whereas the toolstring is conveyed from surface and reaches a proximity distance with the untethered sensing object inside the well fluid of a wellbore. The untethered sensing object includes at least one sensor, an acquisition module, a recording module and a transmitting module.
