摘要： A method of deep acid stimulation for a zone to be treated in an underground formation using an acidizing tool, the method including the steps of introducing the acidizing tool into the well bore, introducing the acid formulation onto the well bore wall at the treatment zone and introducing ultrasound energy into the underground formation at the treatment zone. The subsequent acid penetration depth is deeper than the initial acid penetration depth. A method of stress fracturing a portion of an underground formation includes the steps of introducing the acidizing tool into a well bore and introducing the acid formulation and the ultrasound energy at the focused treatment point. The weakened acidized spots in combination with the stress on the underground formation causes oriented stress-induced fractures to form that are fluidly coupled with the well bore. An acidizing tool includes an acid delivery system and an ultrasonic transmitter.

摘要： An aqueous buffered treatment solution for removing mud cake from a well bore treatment site is made by inducing an elevated temperature in an aqueous pre-buffer solution. The aqueous pre-buffer solution is made of an acid precursor that hydrolyzes into a treatment acid, a conjugate base salt that forms the conjugate base of the acid, and an aqueous fluid. Inducing the elevated temperature forms the treatment acid. The treatment acid is operable to remove mud cake. A method for removing a portion of mud cake from a treatment site using an aqueous buffered treatment solution to establish flow-back includes the step of introducing the aqueous pre-buffer solution to the treatment site. The introduction occurs such that the pre-buffer solution fluidly contacts the mud cake. The hydrocarbon-bearing formation induces the elevated temperature in the solution. Reaction between treatment acid and the acid-reactive constituents removes a portion of the mud cake.

摘要： An aqueous viscoelastic solution for use in a modified water alternating gas (WAG) hydrocarbon production method includes a viscoelastic surfactant and a salt in an aqueous base solution. A modified water alternating gas (WAG) method for producing hydrocarbons from a hydrocarbon-bearing formation includes the step of introducing the aqueous viscoelastic solution into the hydrocarbon-bearing formation. The method also includes the step of introducing a service gas into the hydrocarbon-bearing formation. The aqueous viscoelastic solution and the service gas are introduced separately and sequentially into the hydrocarbon-bearing formation. The hydrocarbon-bearing formation produces a production fluid in response to each introduction. The production fluid contains both water and hydrocarbons.
