Abstract
A technique facilitates a drilling operation, e.g. a land-based drilling operation, by enabling a substantial reduction in the number of equipment components. According to an embodiment, a mud pump assembly is provided with at least one mud pump located on a rig positioned at a wellsite. Electric power is provided to the rig to enable operation of the rig, including operation of the mud pumps when pumping mud downhole to facilitate drilling of a borehole. The rig's electric power also is used to operate a cement mixer for mixing a cementing fluid. This cementing fluid may be pumped downhole during a cementing operation by the same mud pumps employed during the mud pumping operation.
Claims15
A method for reducing equipment employed in a drilling operation at a wellsite, comprising:
- providing a mud pump assembly with mud pumps positioned on a rig located at the wellsite;
- delivering electric power to the rig to enable operation of the rig;
- using the electric power provided to the rig to operate a cement mixing system to mix a drilling mud;
- using a transformer to adjust a voltage of the electric power supplied to the cement mixing system;
- using the electric power provided to the rig to operate the mud pumps during a mud pumping operation in which the drilling mud is pumped downhole to facilitate drilling of a borehole;
- further using the electric power to operate the cement mixing system to mix a cementing fluid;
- and
- subsequently utilizing the mud pumps to pump the cementing fluid during a cementing operation.
A system for use in a well, comprising:
- a rig located at a wellsite, the rig having a rig power supply;
- one or more drilling components positioned on the rig;
- a mud pump assembly having a plurality of mud pumps, the mud pump assembly being positioned on the rig;
- a cement mixing system coupled to the rig, the cement mixing system being operable to mix a cementing fluid which is used during a cementing operation with respect to the well, wherein the one or more drilling components, the mud pump assembly and the cement mixing system are powered via the rig power supply;
- and
- a generator interface box to enable connection and disconnection of the cement mixing system to the rig power supply without disruption of the rig power supply for the one or more drilling components and the mud pump assembly.
