摘要： A mixing apparatus includes an outer housing, or pressurized chamber, and an inner housing rotatably disposed in the outer housing. A bulk material inlet is defined at the upper end of the inner housing. The outer housing has a liquid inlet for the introduction of liquid. The inner housing has a plurality of liquid inlet ports for receiving liquid from the inner housing. The bulk material and liquid are mixed in the rotatable inner housing and pass through an exit of inner housing into the pressurized chamber. The slurry then passes out of the pressurized chamber through an outlet in the pressurized chamber. A rotor is disposed in and is connected to the inner housing. Rotation of the rotor causes rotation of the inner housing.

摘要： Changes occurring downhole during a fracturing process can create or reflect pressure signals. Capturing and evaluating such pressure waves during fracturing enables personnel to monitor, in real time or later, what happens downhole. When a fracture extends, a burst of acoustic noise is embodied in a pressure wave or signal, as is noise coming from other sources. By transforming time-based pressure signals to a frequency base, one can monitor this acoustic noise. In a particular implementation, a waterfall plot of frequency spectra at successive time slices of the original signal is used to determine frequency ridges, such as a ridge of decreasing frequencies indicates fracture extension and a ridge of increasing frequencies indicates either closure or proppant backing up in the fracture. Filtering, such as wavelet filtering, can be used. A fracturing process can be controlled in response to determining whether the fracture is extending.

摘要： A method and apparatus for generating foam cement and placing foam cement in an annulus between a casing and a wellbore. The method includes the steps of displacing cement downwardly in the casing and injecting a gas, preferably nitrogen, into the cement at a predetermined location downhole in the casing. The nitrogen may be injected through a ported sub. The ported sub may be connected in a tubing string that is lowered in the casing. The ported sub has a plurality of ports, which may have nozzles connected therein, that communicate a central opening through the ported sub with an annulus between the ported sub and the casing. The rate at which nitrogen is injected into the cement preferably increases from a leading edge of the cement to a trailing edge of the cement so that a consistent foam cement quality is achieved.

摘要： A surface switchable down-jet/side-jet apparatus. The apparatus comprises a housing with a valve sleeve slidably disposed therein. When the valve sleeve is in a first position, fluid pumped into the apparatus will be jetted out of at least one longitudinally directed port. An actuator, such as a ball, is dropped into the apparatus to seat on the valve sleeve, and when pressure is applied thereto, forces the valve sleeve downwardly, shearing a shear pin. The valve sleeve is moved downwardly to a second position in which at least one transverse port in the housing is uncovered and the longitudinal port is closed. Additional fluid pumped into the apparatus is jetted radially outwardly through the transverse port.
