Abstract
A method, system, and apparatus for determining the location of a tool traveling down a wellbore by measuring a first borehole magnetic anomaly with respect to time at two known locations on a tool, comparing the time difference between the two measurements, then calculating the velocity of the tool based on the comparison, then further calculating the distance traveled by the tool in the wellbore based on the velocity calculation, then executing a series of commands at a predetermined location in the wellbore.
Claims19
A method for locating a downhole tool comprising:
- inserting an autonomous tool into a borehole;
- activating the autonomous tool by removing a safely clip attached to a lanyard when the autonomous tools is released into the borehole;
- moving the autonomous tool down the borehole;
- centralizing the autonomous tool in the borehole;
- programming the autonomous tool to execute a command at a predetermined location within the borehole;
- detecting a set of borehole magnetic anomalies at a first location on the autonomous tool;
- detecting the set of borehole magnetic anomalies at a second location on the autonomous tool;
- comparing the detection at the first location with the detection at the second location;
- calculating the velocity of the autonomous tool based on the comparison the set of borehole magnetic anomalies measured at the first location and second location;
- calculating the position of the tool based on the calculated velocity;
- automatically braking the autonomous tool as it approaches a predetermined location;
- arming an explosive device using a plurality of safety switches;
- holding the autonomous tool at a predetermined location;
- and
- autonomously activating at least one downhole device at the predetermined location.
