  • Patent number: 9944843
    Abstract: Formulations and methods for stimulating the production from wells in nano-darcy shale formations. In one embodiment, the method includes injecting a treatment mixture containing a metal complexing agent into a nano-darcy shale formation adjacent to a well at a pressure below the fracture pressure of the formation. A sufficient contact time is allowed and then the treatment mixture is pumped from the subsurface. This has been shown to stimulate well production in shale formations. Without being held to a particular theory it appears that the metal complexing agent is binding with naturally occurring metals in the shale formation, and particularly divalent metal ions, which are then extracted with the spent fluid. This removal of naturally occurring metals may be increasing the permeability of the formation in the contact region adjacent to the well, thereby causing the observed increased production.

  • Patent number: 9109992
    Abstract: One of the challenges of modern hydrocarbon production is the efficient sealing of a lost circulation zone. It has been discovered that it is possible to efficiently seal the fractures of lost circulation zones by formulating a fracture sealing composition based on a width of the fracture. In particular, it has been found that when the spurt loss volume is less than or equal to the fracture volume capacity of the fracture, then the sealing fluid can be pumped into the wellbore to form a sealing relationship with the fracture.

  • Patent number: 8985204
    Abstract: The invention describes a method for treating near-wellbore zones involving the steps of injecting a magnesium metal with a catalyst into the desired area of the formation to be treated. Subsequently, combustive-oxidizing solution (COS) is injected into the zone of the formation to be treated. The COS initially reacts with the magnesium, which in turn initiates a vigorous oxidation reaction of the COS. The reaction gases and heat produced by the COS oxidation reaction are harnessed to enhance the productivity of the well by creating fractures in the treatment zone and by melting of paraffin and resin deposits in the treatment zone. As a final step, acid is injected into the formation to react with the formation thereby further enhancing the porosity of the fractures. In one embodiment, the COS uses ammonium nitrate as the oxidizer, and in another, urea or ethylene glycol may be added as a reaction fuel.

    Abstract: The present invention discloses liquid quaternary ammonium salts that can be used to treat and coat the surfaces of the proppant sand or inorganic particles that are used in down-hole oil well fracturing operations as well as the containment structure and that these treated surfaces will cause water and oils to flow faster through the porous structure. These liquid quaternary ammonium salts can be chosen from a list that includes but is not limited to cocobis(2-hydroxyethyl)ethylammonium ethyl sulfate, benzylcocobis(hydroxyethyl)ammonium 2-ethyl-hexylsulfate, dibenzylcocobishydroxyethyl ammonium phenolsulfonate, didecyldimethyl-ammonium dodecylbenzenesulfonate and tallow-bis(2-hydroxyethyl)ethylammonium ethyl sulfate.

  • Publication number: 20150034315
    Abstract: A method includes providing an oilfield treatment fluid including an aqueous HCl solution having greater than 15% HCl by weight, and a fixing agent (FA) in a molar ratio of FA:HCl of between 0.5 and 2.5 inclusive. The FA is urea and/or a urea derivative. The oilfield treatment fluid further includes a viscosifying agent that is not a plant-based polysaccharide gum. The method further includes providing the oilfield treatment fluid to a high pressure pump, and operating the high pressure pump to treat a formation fluidly coupled to a wellbore.

  • Publication number: 20150000911
    Abstract: Apparatus and methods of treating a subterranean formation including introducing a coiled tubing string into a wellbore to a wellbore zone, wherein the string comprises a packer on a bottom hole assembly; introducing an acid fracture treatment through the string; introducing bridging fluid comprising particulates through the string; circulating a portion of fluid in the wellbore; introducing a final portion of fluid with a higher concentration of particulates to further form and consolidate bridge-packer, wherein the concentration of particulates in the final portion of fluid is higher than the introducing the bridging fluid comprising the particulates; squeezing the bridging fluid to isolate a perforation into the zone; moving the string to next zone; and repeating introducing and moving.

  • Publication number: 20140374108
    Abstract: A method of hydraulically fracturing a subterranean formation is provided. The method comprises generating a primary fracture using a fracturing fluid. The method further comprises extending the primary fracture and/or creating micro fractures about the primary fracture by initiating a chemical reaction such as an exothermic reaction at about the primary fracture. In one embodiment, the fracturing fluid is used to convey one of the reactive components participating in the chemical reaction.
