Patent number: 11391105Abstract: A method and system for downhole pulse generation determines an optimal frequency and, in some embodiments, amplitude of axial pressure pulses to maximize the rate of penetration. Specifically, one or more sensors may be disposed on or near an axial oscillation tool that provides near real-time raw sensor data relating to speed, velocity, and acceleration of the tool. With this sensor data, an optimal set of parameters, namely an optimal frequency and, in some embodiments, amplitude may be determined based on the hydraulic conditions and frictional forces of the actual drilling environment. An optimizing control system may directly communicate these parameters to the axial oscillation tool or pass the parameters to an axial oscillation tool control system that controls the operation of the tool. Advantageously, frictional forces may be substantially reduced, the rate of penetration may be substantially enhanced, and power consumption may be intelligently managed.Type: GrantFiled: July 2, 2020Date of Patent: July 19, 2022Assignee: QUANTUM ENERGY TECHNOLOGIES LLCInventors: David A.

Publication number: 20010029701Abstract: There is provided a water-hydrocarbon mixture. In one example, the mixture includes low-molecular weight hydrocarbon and between about 5% and about 70% water. The mixture is in the gaseous state, and is at a pressure that is below the critical pressure of the mixture. The mixture temperature is above about 28° C. less than the boiling point temperature of water at the mixture pressure and is below about 450° C. The mixture provides a local environment of water molecules, tending to limit hydrocarbon polymerization and other undesirable side reactions and keeping the hydrocarbon from precipitating from the mixture, for a faster, more complete combustion cycle characterized by lower emissions of carbon monoxide, unburned hydrocarbons, and volatile organic and polyaromatic hydrocarbons. The hydrocarbon preferably includes hydrocarbon micro-droplets of a diameter of no more than about 1 &mgr;m.Type: ApplicationFiled: January 24, 2001Publication date: October 18, 2001Applicant: Quantum Energy TechnologiesInventors: Brian S.

Patent number: 6240883Abstract: There is provided a water-hydrocarbon mixture. In one example, the mixture includes liquid hydrocarbon and between about 5% and about 70% water. The mixture is at a pressure that is below the critical pressure characteristic of the mixture and is at a temperature that is at least the greater of about 250° C. and about the boiling point temperature of water at the mixture pressure. The mixture provides a local environment of water molecules, tending to limit hydrocarbon polymerization and other undesirable side reactions and keeping the hydrocarbon from precipitating from the mixture. This provides for a faster, more complete combustion cycle that is characterized by lower emissions of carbon monoxide, unburned hydrocarbons, and volatile organic and polyaromatic hydrocarbons.

Patent number: 5958573Abstract: An electroluminescent device is disclosed which has an electron conductor fabricated from a stable low electron affinity substance in combination with an emitting species and a hole conductor. The hole conductor and the electron conductor transport to opposed sides of the emitting species holes and electrons respectively that cause the emitting species to undergo a quantum change of state and generate light. In one embodiment the electron conductor is comprised of a plurality of structured particles, each in electrical communication with each other, where the plurality of structured particles are small enough so as their properties deviate from the bulk properties of the substance from which the structured particles are fabricated. In this embodiment the plurality of structured particles are also crystalline in nature. The plurality of structured particles are also in contact with an emitting species and act as an electron conductor.Type: GrantFiled: February 10, 1997Date of Patent: September 28, 1999Assignee: Quantum Energy TechnologiesInventors: Mark Spitler, Christina Lampe-Onnerud, Per Onnerud
