Embodiments of the disclosure include an unmanned submersible vehicle for use in surveying subsurface wells. The unmanned submersible vehicle may be inserted into a well and may acquire measurements while traversing the well and at various measurement locations in the well. The unmanned submersible vehicle may include propulsion units having propellers and an arm pivotably attached to a body of the vehicle. The propellers of the propulsion units may be used to measure flow velocity of a fluid when the unmanned submersible vehicle is in a well. The unmanned submersible vehicle may include a measurement unit for measuring temperature, pressure, and gradient.
