Down hole tool and method
First Claim
1. A down hole apparatus comprising:
- a body adapted to operate in a bore hole without a wired connection to the surface;
a power supply located within the body; and
a control system located within the body and designed such that while the body is operating in a bore hole without a wired connection the apparatus can operate independently without requiring intervention from the surface.

Abstract
A down hole tool and apparatus is described for logging and/or remedial operations in a wellbore in a hydrocarbon reservoir. The tool comprises an autonomous unit for measuring down hole conditions, preferably flow conditions. The autonomous unit comprises locomotion means for providing a motion along the wellbore; means for detecting the down hole conditions; and logic means for controlling the unit, the logic means being capable of making decisions based on at least two input parameters. It can be separably attached to a wireline unit connected to the surface or launched from the surface. The connection system between both units can be repeatedly operated under down hole conditions and preferably includes an active component for closing and/or breaking the connection.
