Abstract
A technique is provided to limit the number of vehicles required during a well project involving a plurality of well construction related procedures. The technique utilizes a modular unit, e.g. a vehicle, and a plurality of modules that may be interchanged on the modular unit according to the scheduled well procedure. A separate crane unit can be used to move the modules to and from the vehicle as required for specific phases of well construction.
Claims9
A method for reducing the number of oilfield equipment carrying vehicles comprising:
- deploying a first vehicle adjacent a wellbore penetrating a subterranean formation, said first vehicle comprising a cement pumping unit and a first mounting region, wherein a first interchangeable well process module is mounted on said first mounting region;
- deploying a second vehicle adjacent the wellbore, said second vehicle comprising a crane, a second mounting region, and a third mounting region, wherein a second interchangeable well process module is mounted on said second mounting region and a third interchangeable well process module is mounted on said third mounting region;
- performing a first oilfield operation at the wellbore by utilizing the first interchangeable well process module;
- replacing, with the crane, the first interchangeable well process module with the second interchangeable well process module;
- performing a second oilfield operation at the wellbore by utilizing the second interchangeable well process module;
- further comprising a control system located in the first vehicle or the second vehicle, the control system being designed to control one or more of the first oilfield operation and the second oilfield operation.
