Cement and drilling mud often exhibit major differences in their specific gravity. This differential in specific gravity will often result in the heavier cement swapping places with the lighter drilling mud. This change in the placement of cement can create a variety of problems. ™ The Para-Bow tool gets its name from the two umbrella-shaped bows that extend in opposite directions in the wellbore to form a temporary plug. When cement is pumped directly above the positioned Para-Bow tool, the success of the cement bond can be improved by as much as 50%—significantly enhancing wellbore integrity and minimizing environmental risks. 2 With Para-Bow tool Compounding these problems is the chemical reaction that can take place between the cement and the drilling fluid. If the fluids displace one another and mix together, the resulting fluid becomes a mud and cement mixture that may fail to offer the bonding characteristics required. A variety of fluid plugs have been tested over the years with mixed success. Our Para-Bow tool is the most cost-effective solution for achieving balanced plug cementing.

OD tool: 4 in. (105 mm) Min. ID string: 21/4 in. (57 mm) Length: 79 in. (2013 mm) Weight: 99 lbm (45 kg) Break circulation Activate Para-Bow device Set Para-Bow tool Pump cement Extrusion pressure: 580 psi (40 bar) Connection: 27/8-in. EUE Simple activation and a flexible design The single ball-drop activation makes it a simple, trouble-free procedure. After the optimum tool depth is reached, the ball is dropped and lands in the activator piston. Pressure is then applied to move the activator piston to close the upper circulation ports. Diverter tool included Once the upper circulation ports are closed, the ball is pushed through the activator piston, allowing the fluid to be pumped against the extrusion piston to push out the Para-Bow tool. The Para-Bow tool is designed for use in all cased or openhole sizes, from 6 to 20 in (15 to 50 cm). 1 2 3 4 5 6 7 8 Para-Bow extrusion tool 1. 27/8-in. EUE threads 2. Outer mandrel 3.
