Apparatus and method for performing earth borehole operations

An apparatus for connecting the tubing of a coiled tubing injector to a bottom hole assembly comprising:

• a base;
• a mast mounted on said base;
• a top drive mounted on said mast for longitudinal movement therealong, said top drive having an opening therethrough;
• a coiled tubing injector mounted on said mast above said top drive such that coiled tubing from said coiled tubing injector can pass through said opening in said top drive;
• and
• a rotary table mounted on said base, said rotary table being operable to engage and manipulate a first component of a bottom hole assembly, said top drive being operable to engage and manipulate a second component of a bottom hole assembly, said top drive and said rotary table being cooperatively operable to make up a complete bottom hole assembly, said coiled tubing injector being selectively operable to move coiled tubing through said opening in said top drive into and out of engagement with said complete bottom hole assembly.

A method of performing earth borehole operations comprising:

• providing a base;
• providing a mast mounted on said base;
• providing a top drive mounted on said mast for longitudinal movement therealong, said top drive being operable to engage and manipulate components used in earth borehole operations, said top drive having an opening therethrough;
• providing a coiled tubing injector mounted on said mast above said top drive such that coiled tubing from said injector can pass through said opening in said top drive;
• providing a rotary table on said base;
• selectively using said top drive to engage and manipulate a component used in earth borehole operations while said coiled tubing injector is substantially inoperative;
• and
• selectively using said coiled tubing injector to inject coiled tubing into said earth borehole while said top drive is substantially inoperative, said coiled tubing passing through said opening in said top drive.

An apparatus for performing earth borehole operations comprising:

• a base;
• a mast mounted on said base;
• a coiled tubing injector mounted on said mast for longitudinal movement therealong;
• a top drive mounted on said mast for longitudinal movement therealong, said top drive being mounted below said coiled tubing injector, said top drive having a first position wherein said coiled tubing injector can pass through said top drive and a second position wherein coiled tubing from said coiled tubing injector can pass alongside said top drive.
