  • Method for acid stimulating a subterranean well formation for improving hydrocarbon production
    Patent number: 6719054
    Abstract: A method of stimulating a downhole formation according to which a plurality of jet nozzles are located in a spaced relation to the wall of the formation to form an annulus between the nozzles and the formation. An acid-containing, stimulation fluid is pumped at a predetermined pressure through the nozzles, into the annulus and against the wall of the formation. A gas is pumped into the annulus so that the stimulation fluid mixes with the gas to generate foam before the mixture is jetted towards the formation to impact the wall of the formation.
    Type: Grant
    Filed: September 28, 2001
    Date of Patent: April 13, 2004
    Assignees: Halliburton Energy Services, Inc., Petro-Canada
    Inventors: Alick Cheng, Jim B. Surjaatmadja, Matthew J. Rees, Abraham Khallad, Keith A. Rispler
  • System and method for fracturing a subterranean well formation for improving hydrocarbon production
    Patent number: 6662874
    Abstract: A method of fracturing a downhole formation according to which a plurality of jet nozzles are located in a spaced relation to the wall of the formation to form an annulus between the nozzles and the formation. A non-acid containing stimulation fluid is pumped at a predetermined pressure through the nozzles, into the annulus, and against the wall of the formation, and a gas is introduced into the annulus so that the stimulation fluid mixes with the gas to generate foam before the mixture is jetted towards the formation to form fractures in the formation.
