Abstract
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.
Claims16
A method of operating a well cementing unit, comprising:
- automatically expanding the capacity of an expandable hopper that is open to the atmosphere and is able to accommodate a predetermined amount of fibrous fluid-loss reduction additive, the hopper being positioned above a feeder equipped with integral constant-pitch dual screws;
- delivering the fibrous fluid-loss reduction additive into the hopper;
- and operating the feeder to meter the fibrous fluid-loss reduction additive into a mixing tank of a transportable cementing unit, the mixing tank being located below the feeder.
A method for use in well servicing operations, comprising:
- delivering a fibrous additive into a hopper that is open to the atmosphere and mounted on a transportable well servicing unit;
- automatically expanding the capacity of the hopper to guide the additive into a feeder positioned below and equipped with integral dual screws;
- and operating the feeder to meter the fibrous additive into a mixing tank at a controlled rate.
