Abstract
Embodiments disclosed provide a pump assembly including a first pump for delivering at least one fluid. The first pump may include a first inlet coupled to the first pump for delivering at least one first fluid to the first pump, a second inlet coupled to the first pump for delivering at least one second fluid to the first pump, a first discharge coupled to the first pump for delivering the at least one first fluid at a first pressure, and a second discharge coupled to the first pump for delivering the at least one second fluid at a second pressure. In some embodiments, the first discharge and the second discharge are isolated from each other.
Claims20
A pump assembly comprising:
- a first pump for delivering at least one fluid, the first pump comprising;
- a first inlet coupled to the first pump for delivering at least one first fluid to the first pump;
- a second inlet coupled to the first pump for delivering at least one second fluid to the first pump;
- a first discharge coupled to the first pump for delivering the at least one first fluid at a first pressure;
- and
- a second discharge coupled to the first pump for delivering the at least one second fluid at a second pressure,
- wherein the first discharge and the second discharge are isolated from each other.
The pump assembly further comprising:
- a second pump for delivering the at least one second fluid, the second pump comprising:
- a third inlet coupled to the second pump for delivering the at least one second fluid to the second pump;
- a third discharge coupled to the second pump for delivering the at least one second fluid at the second pressure;
- wherein the third inlet is further coupled to the first inlet to receive the at least one first fluid and the third discharge is further coupled to the first discharge for delivering the at least one first fluid at the first pressure.
A well operation facility comprising:
- a first pump for delivering at least one fluid to the borehole;
- a first inlet coupled to the first pump for delivering a first fluid to the pump;
- a second inlet coupled to the first pump for delivering a second fluid to the pump;
- a cement mixing system for delivering a cement slurry to the first inlet;
- a mud mixing system for delivering mud to the second inlet;
- a first discharge coupled to the first pump for delivering the cement slurry to a rig cementing line;
- and
- a second discharge coupled to the first pump for delivering the mud to a rig mud line.
A method of delivering a fluid to a borehole, the method comprising:
- feeding a first fluid to a first pump;
- pumping the first fluid to the borehole through the first pump and a first discharge;
- feeding a second fluid to the first pump;
- circulating a second fluid through the first pump and the first discharge to clean the first pump;
- feeding a third fluid to the first pump;
- and
- pumping the third fluid to the borehole through the first pump and a second discharge.
