Patent number: 10865628Abstract: Systems and methods are provided for maintaining the performance and operational stability of an RF (radio frequency) antenna that is positioned in a hydrocarbon-bearing formation, for heating the formation using electromagnetic energy in the radio frequency range. Contaminants such as water or brine, metallic particulates and ionic or organic materials frequently occur in a wellbore being prepared for RF heating, or in an RF antenna installed in the wellbore. Prior to applying RF electrical energy to the formation, the antenna is decontaminated by circulating a preconditioning fluid through the antenna and recovering a spent fluid for treating and recycle. Decontamination is continued while the spent fluid from the antenna includes, but not limited to, water, metallic particles, ionic species, organic compounds contaminants, etc. An operational power level of radio frequency electrical energy is then applied to the decontaminated antenna for providing thermal energy to the hydrocarbon-bearing formation.Type: GrantFiled: December 18, 2018Date of Patent: December 15, 2020Assignee: CHEVRON U.S.A. INC.Inventors: Gunther H. Dieckmann, Cesar Ovalles

Patent number: 10137486Abstract: Contaminant-containing soil can be remediated by subjecting the soil to microwave irradiation to heat the soil to a combustion temperature of from 150° C. to 1200° C. to initiate combustion. A target amount of the contaminant in the soil is destroyed. An oxidizer gas can be flowed through the soil using a gas blower and at least one gas injection line and controlled at a rate such that a self-sustaining smoldering combustion front is formed that moves through the soil. A microwave absorber additive can be added to the soil to accelerate the heating of the soil. At least one waveguide connected to a source of microwave energy directs microwaves into the soil.Type: GrantFiled: February 27, 2018Date of Patent: November 27, 2018Assignee: CHEVRON U.S.A.
