Abstract: Gravity driven reverse circulator tools are provided and methods of using same. One tool has nested pipes that when fully nested close a hole in one of the pipes, but when the drillstring is lifted, the pipes partially separate under the force of gravity to expose the hole. The other embodiment is similar, but the hole is hook shaped (hook on top as in a walking cane) and a protrusion from the other pipe fits in the hole. Thus, both lifting and rotation are needed open the tool.

Abstract: Methods of plugging a hydrocarbon well by using degradable plugs are provided. When the plug is no longer needed, a degradation fluid or fluids are pumped downhole under high pressure, typically via jet, such that the degradation fluid provides an erosive force to the degradable plug, thus both speeding its degradation and preventing or minimizing the leaving of solid plug material remnants in the well.

Abstract: Method of cleaning sucker rods using a portable cleaning tool containing a rotating brush assembly to remove scale and corrosion residue on the sucker rods is described herein. The brush is annular with an empty or hollow center, such that the rod can penetrate through the hole in the brush. The tool is powered by air compression, and also contains a mechanism of removing the collected debris for disposal. The cleaning tool assembly could be either a standalone device on site placed on a mounted rack, or could be attached to the rod to be cleaned.
