  • Patent number: 10408027
    Abstract: A method of extracting hydrocarbons from a subterranean formation comprises forming a suspension comprising reactive particles and a carrier fluid. The suspension is introduced into a subterranean formation containing a hydrocarbon material. At least a portion of the reactive particles are exothermically reacted with at least one other material within the subterranean formation to form a treated hydrocarbon material from the hydrocarbon material. The treated hydrocarbon material is extracted from the subterranean formation. An additional method of extracting hydrocarbons from a subterranean formation, and a method of treating a hydrocarbon material within a subterranean formation are also described.

  • Patent number: 10385260
    Abstract: An aqueous fracturing fluid comprises an environmentally friendly flowback aid. The flowback aid includes an amine oxide having the formula (CH3)NO(R1)(R2), where R1 and R2 are independently selected from linear or branched alkyl groups having from 8 to 16 carbon atoms. Optionally, the fracturing fluid may further comprise an alcohol ethoxylate of the formula R3—(OC2H4)x—OH, wherein R3 is a linear or branched alkyl group having from 6 to 18 carbon atoms, and wherein x ranges from 3 to 25. One example of an amine oxide is didecylmethyl amine oxide, and one example of an alcohol ethoxylate is ethoxylated isodecylalcohol (also known as ethoxylated isodecanol). The fracturing fluid is introduced through a well bore into the subterranean formation and pressurized to fracture the subterranean formation. The fracturing fluid is then allowed to flow back into the well bore from the subterranean formation.

  • Patent number: 10329907
    Abstract: A method for optimized matrix acidizing, including a method for determining fracture pressure of a formation as a function of bottom hole temperature. First and second cycles of a step up rate test may be performed on the formation to be acidized at first and second test temperatures, respectively. From the first and second cycles, a mathematical relationship for fracture pressure of the formation as a function of bottom hole temperature may be formulated and integrated into a fluid placement simulator. A design matrix acidizing treatment plan accounting for an effect of bottom hole temperature on fracture gradient may simulated, and matrix acidizing treatment thereafter performed according to the design plan, thereby resulting in more accurate matrix acidizing treatment and minimization of inefficient fluid placement by adherence to actual formation fracture pressure limits.

  • Patent number: 10240443
    Abstract: A process for altering a wettability characteristic of a carbonate formation to stimulate oil production includes selecting an oil bearing carbonate formation, injecting a silicide dispersion into the carbonate formation, and reacting the injected silicide dispersion with water. The reaction alters the wettability characteristic of the carbonate formation toward water wettability. The silicide dispersion can include an alkali metal silicide, such as sodium silicide. The reaction generates hydrogen, silicate, and heat that pressurizes the carbonate formation with the generated hydrogen, heats the carbonate formation with the generated heat, and reduces the viscosity of the hydrocarbons in the carbonate formation with the generated silicate. The reaction re-mineralizes the surfaces in the carbonate formation and alters the wettability characteristics of the carbonate formation as a calcium-silicon phase is formed. The hydrocarbons are recovered from the carbonate formation with a production well.
