EverReady™ is a technology that uses the Earth’s magnetic field to measure the distance and direction between two wellbores. It is a non-intrusive method that can be used to locate wellbores safely and accurately, even in difficult or remote locations.
EverReady™ works by measuring the disturbance to the Earth’s magnetic field caused by the presence of a nearby wellbore.
This disturbance is triggered by the casing or drillpipe in the wellbore, which creates a magnetic field of its own. This MWD/Passive Magnetic Ranging system measures this disturbance and uses it to calculate the distance and direction between the two wellbores.
Wellbore Intersection
This is the process of intentionally connecting two wellbores. MWD/Passive Magnetic Ranging can be used to accurately locate the target wellbore and ensure a safe and successful intersection.
Plug and Abandonment
This is the process of permanently closing a well. MWD/Passive Magnetic Ranging can be used to locate the wellhead and ensure that the plug is properly placed.
Fishing Operations
This is the process of retrieving a lost or damaged object from a wellbore. MWD/Passive Magnetic Ranging can be used to locate the object and safely retrieve it.
Safety
Non-intrusive method; does not require the use of wireline tools. This eliminates the risk of wellbore kicks and blowouts.
Accuracy
Typical accuracy of ±1 foot. This accuracy is essential for drilling operations that require precise wellbore placement, such as wellbore intersection and plug and abandonment.
Efficiency
Can be performed on short notice and done remotely. This saves time and money and allows for more efficient drilling operations.
