Cable deployed electrical submersible pump jarring tool and method

Abstract

Improved installation speed and reliability for electrical submersible pumps may be realized through the system and methods disclosed herein. An adjustable jarring device is used to break a release pin, the force of the jarring device can be adjusted based on its height above the pin. In another aspect, the jarring device comprises a secondary weight configured to provide a second at break the shear pin of a tool without requiring resetting it. Another aspect is a tool catcher device that allows for catching and holding the jarring device and dropping it, as well as retrieval of the tool in the event the cable is disconnected.

What is claimed is: 
     
         1 . A jarring device, comprising: 
 an upper weight section, the upper weight section comprising an upper opening and a lower opening centered around an axis, and inner walls defining a housing between the upper and lower openings, and the upper weight section being configured to surround a cable extending through the upper opening;   a jar section, the jar section comprising an upper hole opening and configured to retain a terminal end of a cable in an interior hollow; and   the jar section configured to retain a sleeve that surrounds the terminal end of the cable and that has a larger circumference than the upper hole opening;   the upper weight section is configured to slide in relation to the cable and in relation to the jar section.   
     
     
         2 . The jarring device of  claim 1 , wherein the upper weight section comprises a first modular weight section and a second modular weight section. 
     
     
         3 . The jarring device of  claim 1 , wherein the device is configured to allow the sleeve to slide to an up and down position in the interior hollow of the jar section,wherein the sleeve abuts an interior surface of the interior hollow around the upper hole opening when in an up position. 
     
     
         4 . The jarring device of  claim 3 , further comprising a secondary shear pin coupled to the sleeve, wherein the sleeve is coupled to a secondary weight within the interior hollow, which upon the secondary shear pin breaking causes the secondary weight to drop. 
     
     
         5 . The jarring device of  claim 4 , wherein the secondary weight is of sufficient weight to break a primary shear pin in a running/pulling tool under the jarring device, thereby causing dogs of the running/pulling tool to release. 
     
     
         6 . The jarring device of  claim 4 , wherein the secondary shear pin includes two pins that each have a shear strength of 2,000 lbs to 10,000 lbs. 
     
     
         7 . A jarring device, comprising: 
 an upper weight section, the upper weight section comprising an upper opening and a lower opening centered around an axis, and inner walls defining a housing between the upper and lower openings, and the upper weight section being configured to surround a cable extending through the upper opening; and    a jar section, the jar section comprising an upper hole opening and configured to retain a terminal end of a cable in an interior hollow;   wherein the jar section includes a secondary weight in the interior hollow coupled to the cable via a secondary shear pin, the secondary shear pin configured to break upon the cable being pulled up with sufficient force.   
     
     
         8 . The jarring device of  claim 7 , wherein the secondary shear pin includes at least one pin that has a shear strength of 2,000 lbs to 10,000 lbs. 
     
     
         9 . The jarring device of  claim 7 , wherein the cable includes a power wireline inside. 
     
     
         10 . The jarring device of  claim 7 , wherein the cable has an outer diameter of 0.5 to 2 inches. 
     
     
         11 . The jarring device of  claim 7 , wherein the device is configured to allow a sleeve coupled to the cable to slide to an up and down position in the interior hollow of the jar section, wherein the sleeve abuts an interior surface of the interior hollow around the upper hole opening when in an up position. 
     
     
         12 . The jarring device of  claim 11 , wherein the secondary weight is of sufficient weight to break a primary shear pin in a running/pulling tool under the jarring device, 
       thereby causing dogs of the running/pulling tool to release. 
     
     
         13 . A method of using a jarring device, the method comprising: 
 installing a jarring device on a cable above the wellbore, the jarring device comprising an upper weight section and a jar section;   suspending the upper weight section above the top of the jar section;   dropping the upper weight section into a top surface of the jar section with an impact force;   wherein the impact force resulting from the dropping of the upper weight section is transferred to a primary shear pin in a tool below the jar section.   
     
     
         14 . The method of  claim 13 , wherein if the primary shear pin does not break, then exerting a force on a secondary shear pin that is coupling a secondary weight to the cable, thereby breaking the secondary shear pin;wherein upon breaking the secondary shear pin, the secondary weight is decoupled from the cable, and the secondary weight rams an interior bottom surface of the jar section with a secondary impact force. 
     
     
         15 . The method of  claim 14 , wherein the force is a shearing force and is exerted by pulling up on the cable. 
     
     
         16 . The method of  claim 14 , wherein the secondary impact is transferred to the primary shear pin of the tool, breaking the primary shear pin. 
     
     
         17 . The method of  claim 13 , wherein the tool comprises dogs that are released by the breaking of the primary shear pin. 
     
     
         18 . The method of  claim 13 , wherein a sleeve coupled to the cable is slidable to an up and down position in an interior hollow of the jar section, and the cable is coupled to a secondary shear pin through the sleeve. 
     
     
         19 . The method of  claim 13 , wherein the sleeve has a larger circumference than an upper hole opening of the jar section and the sleeve abuts an interior surface of the upper hole opening when in an up position. 
     
     
         20 . The method of  claim 13 , further comprising adjusting a weight of the upper weight section to be sufficient for breaking the primary shear pin by clamping a modular section to the upper weight section.
