  • Patent number: 11187068
    Abstract: A downhole tool can be advanced downhole a wellbore. The downhole tool can include an electromagnetic source, a directional antenna, and a casing. The casing can either completely or partially consist of ceramic materials. The directional antenna can be oriented to direct electromagnetic radiation generated by the electromagnetic source towards the ceramic materials of the casing. In response to receiving the electromagnetic radiation, the ceramic materials can absorb the electromagnetic radiation, which can cause the ceramic materials to rapidly increase in temperature.

  • Patent number: 11174714
    Abstract: The proposed method is an improved chemical flooding of an oil reservoir, especially one containing heavy oil or bitumen, that is cheaper than traditional chemical flooding techniques. This is obtained by viscosifying the displacing phase with a polyol, such as glycerol and/or its derivatives. Glycerol and its derivatives are an excellent additive because they are cheaper than the more commonly used chemicals, work only as a viscosifying agent, do not alter the reservoir properties, and have a wide range of viscosity facilitating the displacement of a wider range of heavy oils. This improved chemical flooding can be used with any other enhanced oil recovery technique, including thermal means, solvent assisted and polymer floodings.

  • Patent number: 11168244
    Abstract: Disclosed herein are compositions and methods for increasing recovery, or flowback, of hydrocarbon compounds from hydrocarbon-containing subterranean reservoirs. The flowback compositions include an anionic sulfonated surfactant, an amphoteric surfactant, water, and a coupling agent. The flowback compositions convert oil-wet rocks to water-wet, yet exhibit a low tendency of composition components to sorb to the rock. The flowback compositions do not cause formation of emulsions with hydrocarbon compounds within the subterranean environment. The flowback compositions are particularly useful for increasing the yield of hydrocarbons recovered from tight shale reservoirs.

  • Patent number: 11125068
    Abstract: The present invention relates to a channel fracturing method with alternative injection of conventional and capsule-type soluble proppants. The method includes the following steps: injecting pad fluid into a wellbore to break a formation and form fractures in the formation; alternately injecting a sand-carrying fluid containing conventional proppant and a sand-carrying fluid containing capsule-type soluble proppant into the wellbore in sequence to support fractures in the formation and continue to fracture the formation; injecting displacement fluid into the wellbore to completely displace the sand-carrying fluids in the wellbore into the fractures. The conventional proppant of less dosage is used. The capsule-type soluble proppant is less difficult to be developed and its solubility is sensitive to the fracture closure, which is conducive to the quick flowback after fracturing.
