摘要： A method of controlling fines migration in a wellbore penetrating a subterranean formation, the method comprising: introducing into the wellbore a screen mesh in an unexpanded form disposed of a first tubular member having a body with apertures, the screen mesh comprising a degradable material; expanding the screen mesh; injecting a cement slurry into the wellbore to fill open spaces within the expanded screen mesh; allowing the cement slurry to set forming a set cement that reduces or substantially preventing the passage of formation particles from migrating from the subterranean formation into the wellbore; and removing the degradable material of the screen mesh forming a fluid pathway in the set cement, which allows a formation fluid to flow from the subterranean formation into the wellbore.

摘要： An embodiment of a downhole device includes an elongated body configured to be deployed in a borehole in an earth formation, the borehole including a borehole fluid. The device also includes a propulsion system attached to the body and configured to move the device through the borehole. The propulsion system includes one or more rotor blades configured to generate thrust using the borehole fluid. At least part of the one or more rotor blades is disposed external to the elongated body.

摘要： An example method includes implementing a flow control device at an injection point downhole in a borehole of a wellbore operation to collect flow rate data of a fluid injected into the borehole. The method further includes collecting the flow rate data using a flow sensor disposed in the flow control device. The method further includes controlling a chemical injection system based at least in part on the flow rate data.

摘要： A downhole power generator module having a body with one or more couplings that are configured to connect the body to a downhole tool string positioned downhole in a wellbore. An axial passageway is formed through the outer housing and couplings. The power generator module has a pressure-driven electric generator such as a triboelectric or piezoelectric generator positioned within the body. A port in the body enables communication of well fluids from the wellbore to the generator. Pressure changes in the well fluids are communicated to the pressure-driven electric generator, causing it to autonomously generate electric power downhole. The generated power is provided directly to other downhole tools without intervention from the surface.
