| titleOfInvention | Subsurface release cementing plug |
| abstract | A subsurface release plug release apparatus comprising a mandrel comprising a bottom plug portion, a top plug portion, a work string attachment portion, a first release portion between the bottom plug portion and the top plug portion, wherein the first release portion comprises a controlled strength segment configured to fail structurally and thereby release the bottom plug portion at a first fluid pressure, and a second release portion between the top plug portion and the work string attachment portion, wherein the second release portion is configured to release the bottom plug portion at a second fluid pressure, wherein the first fluid pressure is less than the second fluid pressure, a bottom plug body disposed about the bottom plug portion of the mandrel, and a top plug body disposed about the top plug portion of the mandrel. |
