Abstract
A technique facilitates the pumping of fluids in a well related application while minimizing the number of system components. The system and methodology comprise a plurality of pumps for use at a well site to deliver a well treatment fluid to a desired location. A single driveline is coupled between the plurality of pumps and a motive unit without incorporating a splitter box. The driveline is driven by the motive unit to rotate the plurality of pumps.
Claims34
A system for pumping, comprising:
- a mobile platform;
- a motive unit mounted on the mobile platform;
- a plurality of pumps mounted on the mobile platform;
- a drive shaft forming a driveline driven by the motive unit, the drive shaft being coupled with a solid, direct connection to the plurality of pumps without splitting the driveline;
- and a pump release system in cooperation with the plurality of pumps to enable selective release of at least one of the plurality of pumps from delivering well treatment fluid downhole to perform at least one well treatment operation.
A method of delivering a well treatment fluid, comprising:
- providing a plurality of pumps at a well site;
- coupling a single driveline directly to the plurality of pumps in series without a splitter box;
- engaging the driveline with a motive unit for rotating the driveline and powering the plurality of pumps;
- and
- using a pump release system in cooperation with the plurality of pumps to enable selective release of at least one of the plurality of pumps from delivering well treatment fluid downhole to perform at least one well treatment operation.
A system, comprising:
- a plurality of pumps mounted at a surface location for use in delivering treatment fluid downhole in a well treatment operation;
- a motive unit;
- a single shaft coupling the motive unit to the plurality of pumps without splitting the single shaft;
- and
- a pump release system in cooperation with the plurality of pumps to enable selective release of at least one of the plurality of pumps from delivering well treatment fluid downhole to perform at least one well treatment operation.
