Latest Patents

One of his notable inventions is a casing annulus remediation system designed to lower a flexible hose into an annulus between strings of casing in a petroleum well. This system operates by pressurizing the hose, allowing it to maintain rigidity and be forced down the annulus. The invention addresses the issue of pressure build-up in the annulus due to leaks in the casing. By pumping a heavy liquid, sealant, or other media through the hose, the pressure is effectively reduced. The system includes a tubing nose affixed to the lower end of the hose, which can be inserted hundreds of feet into the well. The internal pressure in the hose is maintained to prevent it from winding during deployment. Once the hose reaches the desired depth, the operator can increase the pressure to open a check valve, allowing the heavy liquid to flow out and displace the lighter well product.

Another patent by Bobbie is similar in function, focusing on overcoming challenges associated with lowering a flexible hose into the annulus for brine displacement. This system also utilizes a nozzle with a burst disk to hold pressure until the desired depth is reached. The heavy liquid is then allowed to flow out, displacing the lighter well product. An injection sealer at the surface seals around the hose, and a gate valve is included for emergency situations.
