  • Patent number: 10982520
    Abstract: The fracturing methods can provide an advantage over the current fracturing methods. The fracturing methods can change the fracture gradient of the downhole subterranean formation. For example, one or more of the fracture gradients of the low and high stress zones of the downhole subterranean formation can be changed. Furthermore, the methods, in relation to current practices, can decrease the extent and/or degree of fracturing within low stress downhole formations and increase the degree of fracturing within high stress formations.

  • Patent number: 10961443
    Abstract: Oil field chemical delivery fluids containing a mixture of a base fluid and microcapsules having an oil field chemical contained within the microcapsule are described. Chemical groups in the outer surface of the microcapsules interact with the base fluid and promote the dispersibility of the microcapsules in the base fluid. Chemical groups in the outer surface of the microcapsules interact with the targeted areas of a hydrocarbon reservoir and promote the substantivity of the microcapsules to the targeted areas of the reservoir. The oil field chemical delivery fluids provide for the placement of microcapsules in a desired location within the well and/or reservoirs using properties such as the density of the microcapsules. Methods of making oil field chemical delivery fluids, systems containing oil field chemical delivery fluids, methods of fracturing rock in a reservoir and tracing the movement of fluid in a hydrocarbon reservoir using these fluids are described.

  • Patent number: 10947827
    Abstract: The invention allows for an increase in formation permeability and well flow rate. In a method for exerting a combined effect on the near-wellbore region of a producing formation, the following are fed separately and consecutively into the near-wellbore region: a process fluid No. 1 with a density of 1.3-1.4 g/cm3, followed by a process fluid No. 2 with a density of 1.6-1.8 g/cm3, which combines with the fluid No. 1. As a result, an exothermic reaction of heat and gas release occurs, producing an increase in temperature and pressure in the near-wellbore region. The process fluids contain hydroreactive mixtures, combustible oxidizing mixtures, and combustion initiators. Process fluid No. 1 contains, as combustion initiator, sodium hydride, NaH, and powdered nanoaluminium, Al. In a second step, a process fluid No. 3, an acidic solution containing hydrochloric acid, is fed into the wellbore.
