Abstract

A relocatable Managed Pressure Drilling system adapted to be operatively connected to an oil rig and comprising: a base; a tank secured to the base and adapted to contain gases used in Managed Pressure Drilling operations; optionally, a manifold secured to the base and operatively connected to the tank and adapted for use in Managed Pressure Drilling operations when connected to an oil rig; wherein said base is adapted to move from a first location to a second location on an oilfield without the use of a crane or picker.

Claims

1. A relocatable Managed Pressure Drilling system, said relocatable Managed Pressure Drilling system adapted to be operatively connected to an oil rig and comprising:

a base;

a tank secured to the base and adapted to contain gases used in Managed Pressure Drilling operations;

wherein said base is adapted to move from a first location to a second location on an oilfield without the use of a crane or picker; and

wherein the tank is equipped with hydraulics and is adapted to move from a horizontal position to a vertical position on said base.

2. The relocatable Managed Pressure Drilling system according to claim 1, further comprising a manifold secured to the base and operatively connected to the tank and adapted for use in Managed Pressure Drilling operations when connected to an oil rig.

3. The relocatable Managed Pressure Drilling system according to claim 1, wherein the tank comprises a stand, said stand comprising an upper extremity secured to the tank and a lower extremity comprising a pivot point connected to the base.

4. The relocatable Managed Pressure Drilling system according to claim 1, wherein the base further comprises a walking system adapted to move said relocatable managed pressure system from said first location to said second location on the oilfield.

5. The relocatable Managed Pressure Drilling system according to claim 4, wherein the walking system comprises:

a plurality of stomper pads secured to the base;

each of said plurality of stomper pads comprising a pair of perpendicular hydraulics;

vertical hydraulics and horizontal hydraulics;

wherein the vertical hydraulics are adapted to lift the stomper pads off the ground while the base rests on the ground and, while the base is off the ground, the horizontal hydraulics slide the stomper pads from a first proximal position to a second distal position.

6. The relocatable managed pressure drilling system according to claim 1, further comprising a wheel system secured to the base.

7. The relocatable Managed Pressure Drilling system according to claim 1, further comprising a cam wheels system adapted to move the relocatable Managed Pressure Drilling system from said first location to said second location on the oilfield.

8. A relocatable Managed Pressure Drilling system, said relocatable Managed Pressure Drilling system adapted to be operatively connected to an oil rig and comprising:

a base;

a tank secured to the base and adapted to contain gases used in Managed Pressure Drilling operations;

wherein said base is adapted to move from a first location to a second location on an oilfield without the use of a crane or picker; and

a cam wheels system adapted to move the relocatable Managed Pressure Drilling system from said first location to said second location on the oilfield.
