The transportable rig of claim 1 , further comprising a control unit to automatically control said transportable drilling rig in real time, wherein said control unit calibrates movement of said moveable pipe arm between raised and lowered positions, depending on the position of the mast assembly relative to said pipe arm base after positioning said transportable drilling rig relative to said well.
8. The transportable rig of claim 1 , further comprising a pipe tub connected to said pipe arm base for holding pipe for said pipe arm.
9. A transportable rig for use with a well, comprising a rig carrier comprising a motorized unit operable for transporting said transportable rig;
a mast assembly mounted to said rig carrier for movement between a lowered position and an upright position;
a first support base connected to said mast assembly and a second support base connected to said mast assembly, wherein said first support base and said second support base are on opposite sides of the well and the mast assembly, wherein said first support base and said second support base further comprise wide flat mats, and wherein said wide flat mats are at least 50 percent and less than 200 percent as wide as said mast assembly;
a pipe arm base connected to said rig carrier, wherein said pipe arm base and said rig carrier are on opposite sides of the well;
a moveable pipe arm operably mounted to said pipe arm base for moving pipe to said mast assembly when said mast assembly is in said upright position; and
at least two connectors mountable on opposite sides of said well which connect said rig carrier with respect to said pipe arm base whereby a relative position of said mast assembly and said pipe arm base is affixed.
10. The transportable rig of claim 9 , wherein said first support base and said second support base extend outwardly from sides of said rig carrier, and wherein said first support base and said second support base extend substantially perpendicular to the well.
11. The transportable rig of claim 10 , further comprising at least one hydraulic actuator which levels said at least one support base to be substantially perpendicular with respect to said mast assembly, wherein said wide flat mats are pushed downwardly by said at least one hydraulic actuator, and wherein said wide flat mats fold upon each other or unfold during retraction and deployment.
12. The transportable rig of claim 10 , wherein said at least one support base is telescopingly extendable in width.
13. The transportable rig of claim 9 , wherein said at least two connectors are directly attached to said pipe arm base and said rig carrier and further comprise hydraulic operators for precise positioning between said pipe arm base and said rig carrier.
14. The transportable rig of claim 9 , further comprising a control unit to automatically control said transportable drilling rig in real time, wherein said control unit calibrates movement of said moveable pipe arm between raised and lowered positions, depending on the position of the mast assembly relative to said pipe arm base after positioning said transportable drilling rig relative to said well.
15. The transportable rig of claim 9 , further comprising a pipe tub connected to said pipe arm base for holding pipe for said pipe arm.
16. A method of erecting a transportable drilling rig for drilling a well, comprising:
providing a rig carrier comprising a motorized unit for transporting said transportable drilling rig;
providing a mast assembly mounted to said transportable drilling rig for movement between a lowered position and an upright position;
providing a first support base connected to said mast assembly and a second support base connected to said mast assembly;
providing a pipe arm base connected to said mast assembly;
providing a moveable pipe arm operably mounted to said pipe arm base for moving pipe to said mast assembly;
lowering said first support base and said second support base to be perpendicular to the transportable rig, wherein said first support base and said second support base extend substantially perpendicularly to the well and are positioned on opposite sides of the well and said mast assembly;
raising said mast assembly to be above said well; and
placing the pipe arm base opposite the well with respect to the transportable drilling rig and providing at least two connectors mountable on opposite sides of said well for connecting said transportable drilling rig with respect to said pipe arm base, whereby a relative position of said mast assembly and said pipe arm base is affixed.
17. The method of claim 16 , wherein said first support base and said second support base are relatively flat and extend outwards from said transportable drilling rig.
18. The method of claim 17 , further comprising providing at least one hydraulic actuator which levels said first support base and said second support base for positioning said first support base and said second support base against a ground surface to support said mast assembly, and wherein said first support base and said second support base further comprise wide flat mats that are pushed downwardly by said at least one hydraulic actuator, and wherein said wide flat mats fold upon each other or unfold during retraction and deployment.
