With a total of five patents to his name, Elliott's work has had a substantial impact on the oil and gas industry.

Latest Patents

Elliott's latest patents include the "Straddle Frac Tool with Pump Through Feature Apparatus and Method." This innovative fracturing tool features spaced releasable packers with an outlet in between. The housing has relatively moving components for opening the frac port between the packers with weight set on the lower packer. Once the frac port is opened, the upper packer is set, and the pumping begins. The upper packer can be released so that tension can be pulled on the lower packer to close the frac port and open a through passage in the housing. In one embodiment, the through passage can be located above the lower packer to a sand jet perforator to clean debris away from the lower packer if it is difficult to release the lower packer or to abrasively perforate through a tubular. The housing outlet can be below the bottom packer to perform a treatment further downhole or to operate another tool. The straddle tool can be run in on coiled tubing.

Another significant patent is the "Delayed Opening Pressure Actuated Ported Sub for Subterranean Use." This ported sub is operated with a pressure actuated shifting sleeve. A first rupture disc is set at a lower pressure than the test pressure for the tubing string that houses the ported sub. The first rupture disc breaks at a lower pressure than the string test pressure to expose well fluids to a disintegrating plug. The plug slowly disintegrates to then expose tubing pressure to a chamber and a second rupture disc, with the chamber configured to have no effect on moving the sliding sleeve. When the tubing pressure is then raised to a predetermined pressure below the test pressure for the string, the second disc breaks, exposing a piston to tubing pressure on one side and trapped low pressure being the opposite side of the string. The differential moves the sleeve to open a port to let tools be pumped into position without a need to perforate.
