摘要： A technique facilitates well servicing operations by utilizing a hopper system to introduce a dry additive into a mixing tank. The hopper system comprises a feeder and a hopper that delivers the dry additive into the feeder. The feeder, in turn, enables introduction of the dry additive into the cement mixing tank in a controlled manner. When the hopper system is used on a transportable cementing unit, the hopper system may be mounted on a cement mixing tank and also may incorporate a hopper that is both expandable to accommodate a greater amount of dry additive and contractible to facilitate transport.

摘要： An oilfield material reservoir is disclosed. The oilfield material reservoir has a body, the body having an upper end, a lower end, a sidewall extending between the upper and lower ends, the sidewall defining a recess within the body, an opening defined by the upper end, and a first orifice defined by the lower end. The oilfield material reservoir is also provided with a metering gate connected to the body at the lower end. The metering gate has a base having a second orifice aligned with the first orifice, and a knife gate connected to the base. The second orifice has a substantially trapezoidal shape. The knife gate is configured to slidably cover the second orifice. A method is also disclosed for controlling a discharge rate of oilfield material within the oilfield material reservoir by adjusting a metering open area of the second orifice according to mathematical modeling equations.

摘要： A system for generating variable frequency tube waves includes a high pressure multiplex pump having a number of plungers, with each plunger operatively coupled to a suction valve on a suction side and a discharge valve on a discharge side. The suction valve or the discharge valve of a first one of the plungers includes an opening, such that the modified plunger on a discharge stroke pushes fluid through the opening in the suction or discharge valve. The system includes a tubular fluidly coupling the high pressure multiplex pump to a wellbore, and a pressure sensor that receives tube waves generated by the high pressure multiplex pump and reflected from the wellbore.
