This is what it takes to support the guys in the field running a three rig program in the L48:
4 x Drilling Managers
4 x Chief Engineers
40 x Drilling Engineers
40 x Completion Engineers
12 x Drilling Techs
8 x Miscellaneous
This is all supported by Global Wells with:
1 x VP
2 x Chiefs
1 x Technology team and manager of a dozen or so
1 x Technical support team of a dozen or so
6 x Miscellaneous
(Assuming a burden if 25% thats an extra 8 people for three onshore rigs)
