HAWK SAFETY TOOL FOR BLOWOUT PREVENTERS

Testing

We have gradually proven the method in size, flow rate, and pressure. The last tests completed demonstrated the feasibility of creating an entanglement in an 11" wellbore with and without a drill pipe. We also demonstrated the ability of the tangled continuous structure to clog an open aperture of 3" diameter in that wellbore and hold a back pressure of at least 10,000 psi. Currently updating this section of the website. Photos coming soon.
